Description

The present disclosure relates to an adhesive set and a method of manufacturing an article using the adhesive set.

In the manufacturing process of an article, a coating bonding method using a liquid adhesive is used to bond each member constituting the article. Examples of the liquid adhesive include a one-component adhesive (Patent Document 1) in which the reaction is started by oxygen and moisture in the air, and a two-component adhesive in which the main agent and the curing agent are separated. As the two-component adhesive, for example, a two-component mixed adhesive in which the reaction is started by mixing the main agent and the curing agent, a liquid material containing the main agent and a liquid material containing the curing agent are separately applied. There are two-component separate coating type adhesives (Patent Documents 2 to 5) in which the reaction starts when they are brought into contact with each other. The two-component separate coating type adhesive is also generally called a honeymoon type adhesive, a non-mixed type two-component curable adhesive, or the like.

Further, a double-sided adhesive tape is also used instead of the liquid adhesive for adhering the members (Patent Document 6). Since an adhesive material is usually used for the double-sided adhesive tape and curing is not required, the members can be adhered regardless of the type of the member, the manufacturing environment of the article, and the like.

However, when bonding members using a liquid adhesive, coating is difficult depending on the location and position of the members, and uneven coating, coating leakage, adhesive squeeze out from the adherend surface, and liquid dripping occur. It will occur. Further, in the case of a two-component mixed type adhesive, it takes time and effort for the process because it takes time and effort to measure and mix the two liquids, and it is difficult to stop the coating work in the middle after mixing the two liquids. Further, in the case of a one-component adhesive, the curability changes depending on the surrounding environment, the state of the adherend, and the like, so that stable adhesiveness cannot be maintained. As described above, the liquid adhesive has a problem that the production of the article is complicated from the aspect of handling and the like.

On the other hand, when the members are bonded using the double-sided adhesive tape, the above-mentioned problems peculiar to the liquid adhesive are unlikely to occur. Further, since the adhesive material does not require curing and curing, the bonding process can be simplified. However, since the adhesive material is inferior in adhesive strength to the adhesive, it is not possible to firmly bond the members for a long period of time, and the heat resistance and weather resistance are also inferior. Therefore, the adhesive strength of the double-sided adhesive tape depends on the surrounding environment. There is a problem that the member is lowered in a short period of time and the member is easily peeled off. Further, when a shear stress is applied to the adhesive surface between the double-sided adhesive tape and the member, misalignment is likely to occur. Among them, when the adhesive surface is a vertical surface or a normal surface, the shear stress in the vertical direction or the normal direction is generated. By hanging, the above-mentioned problems tend to occur easily. For this reason, the members cannot be sufficiently adhered only with the double-sided adhesive tape, and it is necessary to use it in combination with another fixing method such as anchor fixing.

The present inventor has made diligent studies in order to solve the above-mentioned problems of the adhesive and the double-sided adhesive tape when adhering the members in the manufacture of the article. As a result, the present inventor uses an adhesive sheet obtained by forming a two-component separate coating type adhesive into a sheet, thereby compensating for the above-mentioned drawbacks of the adhesive and the double-sided adhesive tape, and adhering the members by taking advantage of both. I learned that it is possible.

In a method for manufacturing an article using a two-component separate coating type adhesive, for example, as disclosed in Patent Documents 2 and 3, two types of liquid materials are usually separately applied to the adherend surface of each member and then each. The members are bonded to each other by bringing the liquid material-coated surfaces of the members into contact with each other and curing them at room temperature. However, the method for producing an article by the coating and bonding method has the above-mentioned problems.

On the other hand, the present inventor uses a two-component separate coating type adhesive, and a pair of an adhesive sheet having an adhesive layer formed from one liquid material and an adhesive composition which is the other liquid material are paired. We have developed an adhesive set. Then, an adhesive sheet was attached to one member, an adhesive composition was applied to the other member, and the surface of the adhesive layer of one member and the coated surface of the adhesive composition of the other member were brought into contact with each other. However, it has been found that curing at room temperature progresses in the same manner as in the coating bonding method, and it becomes possible to firmly bond the members. Further, it has been found that the use of the above-mentioned adhesive set makes it easier to manufacture the article than the coating adhesive method. It should be noted that Patent Documents 2 to 5 do not disclose or suggest the sheet formation of the two-component separate coating type adhesive.

Further, according to the adhesive set, the present inventor can cure the adhesive at a relatively low temperature, so that it is possible to suppress the occurrence of warpage and floating of the member, and the difference in material and expansion rate. It was found that it is possible to combine and bond various members regardless of the above. For example, an adhesive sheet made from a thermosetting adhesive in the form of a sheet has a problem that when members having significantly different materials and expansion rates are bonded together, the members warp or float when the adhesive is heat-cured. The combination of members to be bonded is limited by the material and the like. In particular, when the metal member and the plastic member are bonded together, the above problem becomes remarkable. On the other hand, according to the adhesive set obtained from the two-component separate coating type adhesive, it is possible to cure at a relatively low temperature, so that the above-mentioned problems can be suppressed.

Further, the present inventor has studied an adhesive method using the above-mentioned adhesive set, and an adhesive set in which an adhesive sheet and a liquid adhesive composition are paired is a combination of an adhesive sheet and an adhesive composition. It has been found that since the morphology is different, it is possible to improve the suitability for the member and the reactivity of the adhesive component contained in the adhesive sheet and the adhesive composition.

The method of manufacturing the adhesive set and the article of the present disclosure is based on these findings described above. Hereinafter, the method for manufacturing the adhesive set and the article of the present disclosure will be described in detail. In addition, in this specification, a 1st member and a 2nd member may be simply referred to as a member.

I. Adhesive set First, the adhesive set of the present disclosure will be described. The adhesive set of the present disclosure is an adhesive set having a liquid first adhesive composition and a first adhesive sheet provided with a first adhesive layer, and the first adhesive composition is a first adhesive. The first adhesive layer contains a second adhesive component, and the first adhesive composition and the first adhesive sheet have the first adhesive component and the second adhesive component with each other. It is configured to cure and adhere upon contact.

1 (a) and 1 (b) are schematic views showing an example of a first adhesive sheet in the adhesive set of the present disclosure. The adhesive set is a pair of a liquid first adhesive composition (not shown) and a first adhesive sheet 12. The first adhesive sheet 12 includes a first adhesive layer 24. In the first adhesive composition (not shown) and the first adhesive sheet 12, the first adhesive component contained in the first adhesive composition and the second adhesive component contained in the first adhesive layer 24 come into contact with each other. As a result, it is hardened, exhibits strong adhesive force, and is configured to be able to adhere firmly. The first adhesive sheet 12 may include a separator 23 and a first adhesive layer 24 provided on at least one surface side of the separator 23, and as shown in FIG. 1A, the first adhesive layer A separator may be provided on one side of the first adhesive layer, and as shown in FIG. 1B, separators may be provided on both sides of the first adhesive layer.

FIG. 2 is a process diagram showing an example of an embodiment of an article manufacturing method using the adhesive set of the present disclosure, and is an example of using an adhesive set having the first adhesive sheet 12 shown in FIG. 1 (a). Is. First, as shown in FIG. 2A, the first adhesive composition is applied to the first member 1. Separately, as shown in FIG. 2B, a member 30 with a first adhesive sheet, in which one surface of the first adhesive layer 24 of the first adhesive sheet 12 is bonded to the second member 2. prepare. Subsequently, as shown in FIGS. 2 (c) to 2 (d), the coated surface of the first adhesive composition 22 of the first member 1 and the other of the first adhesive layer 24 of the member 30 with the first adhesive sheet. The separator 23 is peeled off and bonded to the surface. At this time, when the first adhesive composition 22 and the first adhesive layer 24 come into contact with each other, the components in the first adhesive composition 22 and the components in the first adhesive layer 24 diffuse with each other to form the first adhesive. When the first adhesive component contained in the agent composition 22 and the second adhesive component contained in the first adhesive layer 24 come into contact with each other, a curing reaction occurs and the adhesiveness is improved. Then, when the curing reaction is completed, the first adhesive composition 22 and the first adhesive layer 24 become a cured adhesive layer 3 exhibiting a strong adhesive force as shown in FIG. 2 (d), and the cured adhesive layer 3 is formed. The first member 1 and the second member 2 can be firmly bonded to each other. As a result, the article 10 is obtained.

According to the adhesive set of the present disclosure, the first adhesive component contained in the first adhesive composition and the second adhesive component contained in the first adhesive layer of the first adhesive sheet come into contact with each other. It can be cured and can be firmly adhered with the strong adhesive force developed by the curing.

The adhesive set composed of the first adhesive composition and the first adhesive sheet is a first adhesive layer formed from one liquid material of a two-component separate coating type adhesive and a first liquid material of the other. It is separated from the adhesive composition. By forming one liquid material of the two-component separate coating type adhesive into a sheet in this way, the following effects can be obtained.

Normally, when two members are bonded together using a two-component separate coating type adhesive, it is necessary to apply each liquid material to each member, but it is used because one liquid material is pre-sheeted. At this time, it is not necessary to mix the liquid materials, and for one of the liquid materials, it is possible to prevent uneven coating during coating, forgetting to apply, and protrusion from the adherend surface. Further, since one of the liquid materials is made into a sheet, it is possible to control by the thickness, and by bonding the first adhesive sheet to the member, the first adhesive layer is inevitably arranged on the member. Can be done. Therefore, it is also excellent in terms of quality control at the time of manufacturing the article. Further, the two types of liquid materials of the two-component separate coating type adhesive proceed with the curing reaction when they come into contact with each other, but the curing reaction proceeds during storage because one of the liquid materials is separated and formed into a sheet. Since it does not proceed, it is possible to store the first adhesive sheet alone for a long period of time. Therefore, the adhesive set can be used according to the timing of manufacturing the article. In addition, the size of the first adhesive sheet can be adjusted according to the size and shape of the adherend surface. Further, since one of the liquid materials is made into a sheet, the first adhesive sheet and the first adhesive composition have different morphologies, so that it is possible to easily distinguish them, and it is possible to prevent work mistakes during construction. Can be prevented.

Further, in the present disclosure, since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet should be appropriately selected according to the members in consideration of suitability. Can be done. For example, since the first adhesive composition has fluidity, it is suitable for a member capable of increasing the adhesive strength by impregnation of an adhesive such as a concrete material or wood, a member having an uneven surface or a porous surface, and the like. ing. On the other hand, for example, since the first adhesive sheet has low fluidity, it has good position accuracy and thickness accuracy, and is easy to handle. Therefore, by appropriately selecting the first adhesive composition and the first adhesive sheet according to the member, the suitability for the member can be enhanced. For example, conventionally, when bonding dissimilar members, a suitable adhesive differs depending on each member, so that sufficient adhesive strength may not be ensured. However, in the present disclosure, the suitability for a member is enhanced. Therefore, it is possible to secure the adhesive strength.

Further, since the first adhesive composition is liquid, the first adhesive component contained in the first adhesive composition when the first adhesive composition and the first adhesive layer of the first adhesive sheet come into contact with each other. And the second adhesive component contained in the first adhesive layer can be easily diffused, and the reactivity can be enhanced. For example, as compared with the case where two types of liquid materials of a two-component separate coating type adhesive are each made into a sheet and a pair of adhesive sheets are used, and the two adhesive sheets are brought into contact with each other and cured, the first adhesive component and The second adhesive component can be easily diffused, the reactivity can be improved, and the curing rate can be increased.

Hereinafter, each configuration of the adhesive sheet will be described.

A. First Adhesive Composition and First Adhesive Layer The first adhesive composition contains a first adhesive component, the first adhesive layer contains a second adhesive component, and the first adhesive component and the first adhesive layer. 2 The adhesive components can be cured and adhered by coming into contact with each other. Hereinafter, the materials and properties of the first adhesive composition and the first adhesive layer will be described.

1. 1. Material The first adhesive component contained in the first adhesive composition and the second adhesive component contained in the first adhesive layer can be cured and adhered by contacting each other.

Here, the adhesive component means a component that contributes to the curing reaction. Examples thereof include curable organic compounds, curable inorganic materials, curing agents, catalysts, initiators, curing accelerators, reducing agents, acid or alkaline components, acid generators, base generators, water absorbents and the like.

The first adhesive component contained in the first adhesive composition and the second adhesive component contained in the first adhesive layer start a curing reaction by contact, and the curing reaction proceeds as each component diffuses with each other. As a result, substantially uniform curing becomes possible.

The combination of the first adhesive component and the second adhesive component is not particularly limited, but for example, a combination in which a curable organic compound is used as the first adhesive component and a curing agent is used as the second adhesive component, and a curable organic compound. And a combination of the latent curing agent as the first adhesive component and the catalyst and the reducing agent as the second adhesive component, the curable organic compound and the initiator as the first adhesive component, and the reducing agent as the second adhesive component. The combination of the above, the curable organic compound and the initiator as the first adhesive component, the curable organic compound and the reducing agent as the second adhesive component, the curable inorganic material as the first adhesive component, moisture and Examples thereof include a combination in which a catalyst is used as a second adhesive component, a combination in which a curable organic compound and a ph reaction-imparting component are used as a first adhesive component, and an acid or alkali component is used as a second adhesive component. Further, the combination of the first adhesive component and the second adhesive component may be the reverse of these.

The first adhesive composition and the first adhesive layer are two-component separate coating composed of, for example, a liquid material containing a first adhesive component and a liquid material containing a second adhesive component. It can be obtained by using each liquid material of the mold adhesive. Examples of the two-component separate coating type adhesive include conventionally known compositions. Specifically, a primer-type acrylic adhesive (SGA), an acrylic compound, and a radical composed of a liquid A containing an acrylic compound and a radical polymerization initiator and a liquid B containing a reducing agent of a redox polymerization catalyst. Liquid A containing a polymerization initiator, liquid B containing an acrylic compound and a reducing agent for a redox polymerization catalyst, and liquid A containing a two-component main agent type acrylic adhesive (SGA) and a polyol compound. , Liquid B containing a polyisocyanate compound, a urethane adhesive composed of liquid A, a liquid A containing an epoxy compound, and liquid B containing a curing agent such as polyamide, polythiol, and imidazole. Examples thereof include a silicone adhesive composed of a liquid A containing a silicone compound such as an agent and a silicone low polymer, and a liquid B containing a platinum catalyst. The two-component separate coating type adhesive is not limited to these, and can be appropriately selected depending on the material of the adherend and the like. Further, not only the two-component separate coating type adhesive but also a two-component curable paint such as polymer cement can be used.

Hereinafter, the material of the first adhesive composition and the first adhesive layer will be described.

(1) First Adhesive Component and Second Adhesive Component At least one of the first adhesive component and the second adhesive component contains a curable organic compound, a curable inorganic material, or the like. Hereinafter, a case where at least the first adhesive component contains a curable organic compound, a curable inorganic material, or the like will be described. The first adhesive component and the second adhesive component usually have different compositions.

(A) First Adhesive Component The first adhesive component contained in the first adhesive composition may cause a curing reaction with the second adhesive component contained in the first adhesive layer, and the second adhesive component may be used. Due to the presence of the adhesive component, the components contained in the first adhesive component may cause a curing reaction with each other. When a two-component separate coating type adhesive is used for the first adhesive composition and the first adhesive layer, the first adhesive component usually contains at least the main ingredient component in the two-component separate coating type adhesive.

Examples of the first adhesive component include curable organic compounds, curable inorganic materials, and other materials used in combination with these. The first adhesive component may contain either a curable organic compound or a curable inorganic material, or may contain both.

(I) Curable Organic Compound Examples of the curable organic compound include curable organic compounds used in known two-component separate coating adhesives, such as epoxy compounds, acrylic compounds, polyol compounds, and silicone low polymers. Examples thereof include silicone compounds, melamine compounds, phenol compound mixtures, and silyl compounds. These can be appropriately selected depending on the material of the adherend to which the first adhesive composition is applied. For example, if the material of the adherend is wood, ceramic, concrete, or metal, the curable organic compound can be an epoxy compound or a polyol compound. Further, for example, if the material of the adherend is a difficult-to-adhere material such as polypropylene or polyethylene, the curable organic compound can be a silicone compound or an acrylic compound. In addition, the acrylic compound has a high degree of freedom in material, and can be widely used for organic substances such as metals, wood, and ABS.

When the first adhesive component contains an epoxy compound, the epoxy compound can have two or more epoxy groups in one molecule, and an epoxy compound generally used for an epoxy adhesive can be used. For example, bisphenol A type epoxy compounds, bisphenol F type epoxy compounds and other epoxy compounds having a bisphenyl group, naphthalene type epoxy compounds, aliphatic epoxy compounds, glycol type epoxy compounds, pentaerythritol type epoxy compounds, aromatic epoxy compounds. , Modified epoxy compounds such as urethane-modified epoxy compounds and rubber-modified epoxy compounds, and other epoxy compounds disclosed in JP-A-2009-167251. These epoxy compounds may be used alone or in combination of two or more.

The epoxy compound contained in the first adhesive component may be a liquid epoxy compound or a solid epoxy compound. The liquid epoxy compound refers to an epoxy compound that is liquid at room temperature, and the solid epoxy compound refers to an epoxy compound that is solid at room temperature. For example, in the case of a bisphenol A type epoxy compound, if the bisphenol skeleton of the main chain is 1 or more and 3 or less, it can be liquefied at room temperature, and if the bisphenol skeleton of the main chain is 2 or more and 10 or less, it can be liquid at room temperature. It can be solid.

The first adhesive composition may contain at least one of a liquid epoxy compound and a solid epoxy compound, but may contain both. When the first adhesive composition contains a liquid epoxy compound and a solid epoxy compound, the adhesiveness before curing and the adhesive strength after curing can be adjusted by adjusting the respective molecular weights and blending amounts.

The mass average molecular weight and the epoxy equivalent of the liquid epoxy compound can be appropriately set according to the curing rate required for contact between the first adhesive composition and the first adhesive layer. For example, the mass average molecular weight (Mw) of the liquid epoxy compound can be in the range of 200 or more and 900 or less. At this time, the epoxy equivalent (g / eq.) Can be in the range of 100 or more and 500 or less. Within the above range, when the first adhesive composition and the first adhesive layer are brought into contact with each other, the liquid epoxy compound contained in the first adhesive composition permeates into the other first adhesive layer side. It becomes easier and the curing speed can be increased. In addition, the durability and adhesive strength after curing can be improved.

Further, the mass average molecular weight and the epoxy equivalent of the solid epoxy compound can be appropriately set according to the magnitude of the shear stress applied to the coated surface of the first adhesive composition and the direction in which the stress is applied. For example, the mass average molecular weight (Mw) of the solid epoxy compound can be in the range of 900 or more and 6000 or less. Within the above range, durability and adhesive strength can be improved. At this time, the epoxy equivalent (g / eq.) Can be in the range of 450 or more and 5000 or less. This is because, within the above range, the cohesive force and the film-forming property are improved, and the shear stress is strengthened. In addition, the durability and adhesive strength after curing can be improved.

The mass average molecular weight is a polystyrene-equivalent value measured by gel permeation chromatography (GPC). The epoxy equivalent is the number of grams of the compound containing 1 gram equivalent of the epoxy group measured by a method according to JIS K7236: 2009 (How to determine the epoxy equivalent of the epoxy compound).

When the first adhesive composition contains both a liquid epoxy compound and a solid epoxy compound as the epoxy compound, the blending ratio of the liquid epoxy compound and the solid epoxy compound may be set according to the required adhesiveness and cohesive force. can. In order to obtain a coating layer of the first adhesive composition having strong adhesiveness or low cohesive force, the total amount (100% by mass) of the liquid epoxy compound and the solid epoxy compound in the first adhesive composition is increased. The content of the liquid epoxy compound can be 50% by mass or more, particularly 60% by mass or more, and 95% by mass or less, particularly 90% by mass or less. The content of the liquid epoxy compound can be higher than the content of the solid epoxy compound. On the other hand, in order to form a coating layer of the first adhesive composition having weak adhesiveness or high cohesive force, the total amount (100% by mass) of the liquid epoxy compound and the solid epoxy compound in the first adhesive composition is increased. Therefore, the content of the liquid epoxy compound can be 20% by mass or more, particularly 30% by mass or more, and 70% by mass or less, particularly 60% by mass or less. The content of the liquid epoxy compound in the first adhesive composition can be equal to or less than the content of the solid epoxy compound. In general, the stronger the adhesive force, the lower the cohesive force and the more flexible the adhesive layer, while the weaker the adhesive force, the higher the cohesive force and the harder the layer.

When the first adhesive component contains an acrylic compound, the acrylic compound may be either an acrylic monomer or an acrylic polymer. Moreover, the acrylic polymer may be either an acrylic low polymer or an acrylic high polymer. For example, the acrylic compounds disclosed in JP-A-2008-248111 and JP-A-2016-175195 can be mentioned.

When the first adhesive component contains a polyol compound, the polyol compound may have a plurality of hydroxyl groups in the molecule, and examples thereof include polyester polyols, acrylic polyols, and polyether polyols.

When the first adhesive component contains a melamine compound, a mixture of phenol compounds, or a silyl compound, these compounds can be the same as the compounds used in a general two-component separate coating type adhesive.

Above all, the first adhesive component may contain an epoxy compound. This is because the cohesive force and adhesive force after curing are high, and it is possible to adhere to a wide range of materials such as wood, concrete, and ceramic with high strength.

Further, the first adhesive component may contain an acrylic compound. For example, by appropriately selecting an acrylic compound, the physical properties of the first adhesive composition can be adjusted according to the adherend, and thus it is suitable for bonding dissimilar members, for example. Further, the acrylic compound has an advantage that it has good weather resistance and transparency.

(Ii) Curable Inorganic Material As the curable inorganic material, for example, a water-curable inorganic material that cures using water as a catalyst can be used. Specific examples of the water-curable inorganic material include cements such as Portland cement, alumina cement, acid-resistant cement, slag cement, Roman cement and magnesia cement, gypsum, lime and magnesium carbonate.

(Iii) Other components The first adhesive component may contain, for example, a curing agent, a catalyst, an initiator, a curing accelerator, a reducing agent, etc., in addition to a curable organic compound, a curable inorganic material, and the like. These materials can usually be different from the second adhesive component contained in the paired first adhesive layer, and can be used for curable organic compounds, types of curable inorganic materials, and the first adhesive layer. It can be appropriately selected depending on the type of the second adhesive component contained.

For example, when the first adhesive composition contains a curable organic compound as the first adhesive component and the curable organic compound is an acrylic compound, the first adhesive component is in addition to the acrylic compound. For example, a radical polymerization initiator can be included. In this case, the paired first adhesive layer may contain, for example, a reducing agent of the redox polymerization catalyst, or an acrylic compound and a reducing agent of the redox polymerization catalyst as the second adhesive component. Specific examples thereof include radical polymerization initiators such as peroxides and azo compounds disclosed in JP-A-2008-308531.

Further, for example, when the first adhesive composition contains a curable organic compound as the first adhesive component and the curable organic compound is an epoxy compound, the first adhesive component may be other than the epoxy compound. In addition, curing agents such as phenol compounds, amine compounds and thiol compounds generally blended in epoxy compounds, latent curing agents such as dicyandiamide, microcapsule type amines and inclusion catalysts and hydrazides, and cationic catalyst type curing agents. A hardener can be included. In this case, the paired first adhesive layer may contain, for example, a curing catalyst such as aliphatic dimethylurea or aromatic dimethylurea, imidazole, phosphorus-based catalyst, polyamines, etc. as the second adhesive component.

(B) Second Adhesive Component The second adhesive component contained in the first adhesive layer may directly react with the first adhesive component contained in the first adhesive composition, and may be the first. It may induce or promote the curing reaction of the first adhesive component contained in the adhesive composition. The second adhesive component can be appropriately selected depending on the type of the first adhesive component. For example, a curing agent, an acid or alkali component, a curing accelerator, an acid generator, a base generator, a catalyst, and water absorption. Agents and the like can be mentioned.

Examples of the second adhesive component when the first adhesive component contains an epoxy compound include a curing agent. Specific examples of the curing agent include imidazole compounds, phenol compounds, amine compounds, polyamide compounds, acid anhydrides, isocyanate compounds, and thiol compounds. Above all, the curing agent can be an imidazole compound. The imidazole compound has good reactivity with the epoxy compound at room temperature, has a high glass transition temperature (Tg) after curing, is excellent in heat resistance and durability, and has many compounds having a small molecular weight. Therefore, when the first adhesive composition and the first adhesive layer are brought into contact with each other, the curing agent contained in the first adhesive layer easily shifts to the other first adhesive composition containing the epoxy compound. This is because a curing reaction due to contact is likely to occur.

Examples of the second adhesive component when the first adhesive component contains an acrylic compound include a catalyst, a reducing agent, an initiator and the like. Specific examples thereof include radical polymerization initiators such as peroxides and azo compounds disclosed in JP-A-2008-308531, and redox polymerization catalyst reducing agents disclosed in JP-A-2008-81691.

When the first adhesive component contains an acrylic compound, the second adhesive component may also contain an acrylic compound. In this case, the acrylic compounds contained in the first adhesive component and the second adhesive component may be the same or different. When the acrylic compounds contained in the first adhesive component and the second adhesive component are different, for example, by appropriately selecting the acrylic compound, the first adhesive composition and the first adhesive layer can be prepared according to the adherend. Since the physical properties can be adjusted, it is suitable for bonding dissimilar members. When the acrylic compounds contained in the first adhesive component and the second adhesive component are different, the acrylic compound is appropriately selected according to the functions required for the first adhesive composition and the first adhesive layer. can do. For example, when the coating layer and the first adhesive layer of the first adhesive composition are laminated on the first member as described in the fifth embodiment and the seventh embodiment of the method for producing an article described later, the first The first adhesive composition on the member side is required to have adhesive performance, and the first adhesive layer arranged on the outermost surface is required to have a protective function. In this case, the hard coat property can be imparted to the first adhesive layer by appropriately selecting an acrylic compound so that the first adhesive layer arranged on the outermost surface becomes harder after curing. Further, for example, as described in the sixth embodiment and the eighth embodiment of the method for producing an article described later, when the first adhesive layer and the coating layer of the first adhesive composition are laminated on the second member, the most A hard coat property can be imparted to the first adhesive composition by appropriately selecting an acrylic compound so that the coating layer of the first adhesive composition arranged on the surface becomes harder after curing.

Examples of the second adhesive component when the first adhesive component contains a polyol compound include a curing agent. Specific examples thereof include polyisocyanate compounds, and among them, aromatic polyisocyanates such as MDI, crude MDI, and TDI can be used because they are excellent in reactivity with polyol compounds.

Examples of the second adhesive component when the first adhesive component contains a silicone compound include a platinum catalyst.

Examples of the second adhesive component when the first adhesive component contains a melamine compound or a mixture of phenol compounds include an acid or alkaline component such as a hydrogel containing a sulfuric acid aqueous solution and a hydrogel containing sodium hydroxide.

Examples of the second adhesive component when the first adhesive component contains a silyl compound or a curable inorganic material include a solid liquid dispersion colloid. Specific examples thereof include hydrogels, water-absorbent polymers, gelatin and the like. The above-mentioned second adhesive component can be cured by the moisture contained therein.

The content of the second adhesive component can be an amount capable of sufficiently reacting with the first adhesive component when the first adhesive composition and the first adhesive layer come into contact with each other. It can be appropriately set according to the combination and type of the first adhesive component and the second adhesive component. For example, when the first adhesive component contains an epoxy compound and the second adhesive component contains an imidazole compound as a curing agent, the content of the imidazole compound in the first adhesive layer is the epoxy equivalent of the epoxy compound. However, for example, the epoxy compound may be in the range of 0.1 parts by mass or more and 30 parts by mass or less, particularly in the range of 1 part by mass or more and 20 parts by mass or less with respect to 100 parts by mass of the epoxy compound. If the content of the imidazole compound in the first adhesive layer is too large, the adhesion to the adherend may be weakened, while if the content is too small, it may cause curing failure. Is. When the curable organic compound contained in the first adhesive component is a material other than the epoxy compound, the content of the second adhesive component is two liquids when a general-purpose two-component curable adhesive is used. There is no particular problem as long as it does not deviate significantly from the general distribution during curing.

The case where at least the first adhesive component contains a curable organic compound, a curable inorganic material, or the like has been described above, but at least when the second adhesive component contains a curable organic compound, a curable inorganic material, or the like. Can be the other way around.

When only one of the first adhesive component and the second adhesive component contains a curable organic compound, a curable inorganic material, or the like, the first adhesive component contains a curable organic compound, a curable inorganic material, or the like. The second adhesive component may contain a curable organic compound, a curable inorganic material, or the like, and among them, the first adhesive component may contain a curable organic compound, a curable inorganic material, or the like. .. In this case, the one containing the adhesive component containing the curable organic compound or the curable inorganic material has a larger thickness than the one containing the adhesive component not containing the curable organic compound or the curable inorganic material. be able to. Therefore, when the first adhesive component contained in the first adhesive composition contains a curable organic compound, a curable inorganic material, or the like, the coating thickness of the first adhesive composition can be increased. Therefore, for example, when applied to a member having an uneven surface or a porous surface, a sufficient coating thickness can be obtained for the uneven surface or the porous surface.

(2) Phase 2 Soluble Polymer Component The first adhesive layer can further contain a second phase soluble polymer component having compatibility with the second adhesive component. The reason is as follows.

The two-component separate coating type adhesive is usually used by applying two types of liquid materials to each other and then immediately contact-curing each other. However, since each liquid material is inferior in film forming property, each sheet has a desired thickness. There is a problem that it is difficult to maintain the sheet shape for a long period of time when trying to separate and store the sheet. On the other hand, by containing the second phase-compatible polymer component having compatibility with the components of the liquid material, the film-forming property can be improved and the sheet shape can be maintained for a long period of time. .. Further, in the first adhesive layer formed by applying the liquid material, since the component of the liquid material functions as a plasticizer, the second phase-soluble polymer component is further added to the first adhesive layer containing the component of the liquid material. By adding the above, the entire first adhesive layer is plasticized, and the adhesiveness and flexibility of the second phase-soluble polymer component are exhibited. This makes it possible to improve the adhesiveness before curing and the adhesiveness to the adherend, and also improve the toughness of the first adhesive layer after curing and further enhance the adhesive force.

Here, having compatibility with the second adhesive component means that the second adhesive component has a good affinity with the curable organic compound, and in an arbitrary ratio with the second adhesive component. It means that phase separation does not occur when mixed. In the first adhesive layer, the fact that the second phase-soluble polymer component is compatible with the second adhesive component means that, for example, the transparency of the first adhesive layer is high and the haze of the first adhesive layer is high. Low values, no micron-sized islands in the layer when observing the surface or cross section of the first adhesive layer with a scanning electron microscope (SEM) or transmission electron microscope (TEM), etc. You can check from. The same applies to the first adhesive composition described later.

In particular, when the first adhesive composition or the first adhesive layer contains a curable organic compound of any of an epoxy compound, an acrylic compound, and a polyol compound as the first adhesive component or the second adhesive component. The effect of the second phase-soluble polymer component can be more exerted. For example, when the curable organic compound contained in the first adhesive composition or the first adhesive layer is an acrylic compound, the crosslink density tends to be high, but by containing the second phase-soluble polymer component, the acrylic compound The main chain of the compound can be lengthened, that is, the crosslink density can be lowered, and flexibility can be imparted to the first adhesive layer. The manifestation of the effect of the second phase-soluble polymer component when the curable organic compound contained in the first adhesive composition or the first adhesive layer is an epoxy compound will be described later.

In addition, the second phase-soluble polymer component can further have compatibility with the first adhesive component contained in the first adhesive composition. Having compatibility with the first adhesive component means that the first adhesive component has a good affinity with the first adhesive component, and the first adhesive composition and the first adhesive layer come into contact with each other, so that the first adhesive component is compatible with the first adhesive component. It means that the phase does not separate when mixed at an arbitrary ratio.

The second phase-soluble polymer component is not particularly limited as long as it contains a polymer having good compatibility with the second adhesive component. The polymer may have a polar group. Examples of the polar group include an epoxy group, a hydroxyl group, a carboxyl group, a nitrile group, an amide group and the like.

Above all, the second phase-soluble polymer component can be a component containing an acrylic polymer, that is, a compatible acrylic polymer-containing component.

The compatible acrylic polymer-containing component may be a homopolymer in which the acrylic polymer is a homopolymer of an acrylic acid ester monomer and may be a mixed component containing two or more of the homopolymers. It is a copolymer composed of two or more kinds of acrylic acid ester monomers, and may be a component containing one or more copolymers. Further, the compatible acrylic polymer-containing component may be a mixed component of the homopolymer and the copolymer. The "acrylic acid" of the acrylic acid ester monomer also includes the concept of methacrylic acid. Specifically, the compatible acrylic polymer-containing component may be a mixture of a methacrylate polymer and an acrylate polymer, and an acrylic composed of acrylate-acrylate, methacrylate-methacrylate, methacrylate-acrylate and the like. It may be an acid ester polymer. Among them, the above-mentioned acrylic polymer-containing component can contain a copolymer of two or more kinds of acrylic acid ester monomers ((meth) acrylic acid ester copolymer).

Examples of the monomer component constituting the (meth) acrylic acid ester copolymer include the monomer component described in JP-A-2014-065889. The above-mentioned monomer component may have the above-mentioned polar group. This is because the compatibility with the epoxy compound is improved, and the adhesive strength and the adhesive strength after curing can be enhanced. Examples of the (meth) acrylic acid ester copolymer include ethyl acrylate-butyl acrylate-acrylonitrile copolymer, ethyl acrylate-acrylonitrile copolymer, and butyl acrylate-acrylonitrile copolymer. The "acrylic acid" such as methyl acrylate and ethyl acrylate includes "methacrylic acid" such as methyl methacrylate and ethyl methacrylate.

Examples of the (meth) acrylic acid ester copolymer include block copolymers, and further examples include acrylic block copolymers composed of methacrylate-acrylate. The acrylates and methacrylates constituting the acrylic block copolymer include, for example, methyl acrylate, ethyl acrylate, propyl acrylate, butyl acrylate, lauryl acrylate, 2-ethylhexyl acrylate, cyclohexyl acrylate, benzidyl acrylate and the like. Can be mentioned. These "acrylic acids" also include methacrylic acid.

Specific examples of the methacrylate-acrylate copolymer include acrylic copolymers such as a methyl methacrylate-butyl acrylate-methyl methacrylate (MMA-BA-MMA) copolymer. MMA-BA-MMA copolymers also include block copolymers of polymethylmethacrylate-polybutylacrylate-polymethylmethacrylate (PMMA-BA-MMA). Such an acrylic copolymer has improved film-forming properties and can exhibit sufficient adhesiveness to the adherend surface.

The acrylic polymer does not have to have a polar group, or may be a modified product in which the above-mentioned polar group is partially introduced. Since the modified product has further improved compatibility with the epoxy compound, the adhesive strength is further improved.

Among them, the second phase-soluble polymer component has a first polymer portion having a glass transition temperature (Tg) of 10 ° C. or lower and a second polymer portion having a glass transition temperature (Tg) of 20 ° C. or higher. It can be a (meth) acrylic acid ester copolymer. Such a (meth) acrylic acid ester copolymer has a first polymer portion that becomes a soft segment and a second polymer portion that becomes a hard segment. By adding such a copolymer, the first adhesive layer can effectively suppress floating and peeling from the adherend surface, and the toughness after curing is improved to further enhance the adhesive force. Because it can be done.

The expression of the above effects can be estimated as follows. In conventional adhesives, an acrylic polymer is added in addition to a curable organic compound as a main agent, for example, an epoxy compound, in order to impart toughness and flexibility. The addition reduced the heat resistance of the adhesive itself. On the other hand, by using an acrylic polymer having both a soft segment and a hard segment, such as the above (meth) acrylic acid ester copolymer, the hard segment contributes to heat resistance, and the soft segment is tough or flexible. In order to contribute to the properties, it is considered that the first adhesive layer after curing has toughness and can maintain excellent adhesiveness.

At least one of the first polymer portion and the second polymer portion contained in the (meth) acrylic acid ester copolymer has compatibility with the curable organic compound. When the first polymer portion has compatibility with the curable organic compound, the flexibility can be increased. Further, when the second polymer portion has compatibility with the curable organic compound, cohesiveness and toughness can be enhanced.

When either the first polymer moiety or the second polymer moiety is not compatible with the curable organic compound, the (meth) acrylic acid ester copolymer is compatible with the curable organic compound. It will have a compatible moiety, which is a polymer moiety, and an incompatible moiety, which is a polymer moiety that is not compatible with the curable organic compound. In this case, when the above (meth) acrylic acid ester copolymer is added as an acrylic polymer to the adhesive composition containing the curable organic compound, the compatible moiety is compatible with the curable organic compound and the incompatible moiety is present. Is incompatible with the curable organic compound, resulting in phase separation. As a result, a sea-island structure is developed in the first adhesive layer after curing. The sea-island structure includes the type of (meth) acrylic acid ester copolymer, compatibility of the first polymer portion and the second polymer portion contained in the (meth) acrylic acid ester copolymer, and modification by introduction of a polar group. Depending on the presence or absence, for example, the compatible site of the cured product of the curable organic compound and the (meth) acrylic acid ester copolymer is the sea, and the non-compatible site of the (meth) acrylic acid ester copolymer is an island. Sea-island structure or sea-island structure in which the incompatible part of the (meth) acrylic acid ester copolymer is the sea, and the compatible part of the cured product of the curable organic compound and the (meth) acrylic acid ester copolymer is an island. , A sea-island structure in which the (meth) acrylic acid ester copolymer is the sea and the cured product of the curable organic compound is an island. By having such a sea-island structure, the first adhesive layer after curing can easily disperse stress, so that interfacial fracture can be avoided and excellent adhesiveness can be maintained.

The (meth) acrylic acid ester copolymer can be a block copolymer among them, and in particular, ABA in which the compatible site is the polymer block A and the incompatible site is the polymer block B. It can be a block copolymer. Further, A in which the first polymer portion is an incompatible moiety and the second polymer moiety is a compatible moiety, the first polymer portion is the polymer block B, and the second polymer portion is the polymer block A. It can be a −BA block copolymer. By using such an ABA block copolymer as the acrylic polymer, the cured product of the curable organic compound and the phase of the (meth) acrylic acid ester copolymer are contained in the first adhesive layer after curing. In the case of a sea-island structure in which the melting site is the sea and the incompatible site of the (meth) acrylic acid ester copolymer is an island, the island portion can be made smaller. Further, in the case of a sea-island structure in which the incompatible portion of the (meth) acrylic acid ester copolymer is the sea, and the compatible portion of the cured product of the curable organic compound and the (meth) acrylic acid ester copolymer is an island. Alternatively, in the case of a sea-island structure in which the (meth) acrylic acid ester copolymer is the sea and the cured product of the curable organic compound is an island, the sea portion can be made smaller. Therefore, in the adhesive layer after curing, the curable organic compound and the acrylic polymer are apparently in a compatible state. By expressing such an apparent compatible state, the first adhesive layer after curing can further easily disperse stress, so that interfacial fracture can be avoided and excellent adhesiveness can be obtained. Can be maintained.

Further, the (meth) acrylic acid ester copolymer may be a modified product in which the above-mentioned polar group is introduced into a part of the first polymer portion or the second polymer portion. The heat resistance of the first adhesive layer after curing is further improved, and the compatibility with the curable organic compound is also improved, so that the adhesiveness is improved.

The Tg of the first polymer portion contained in the (meth) acrylic acid ester copolymer is 10 ° C. or lower, within the range of −150 ° C. or higher and 10 ° C. or lower, and particularly within the range of −130 ° C. or higher and 0 ° C. or lower. In particular, it can be in the range of −110 ° C. or higher and −10 ° C. or lower.

The Tg of the first polymer portion is calculated by the following formula based on the Tg (K) of each homopolymer described in "POLYMERHANDBOOK 3rd Edition" (published by John Wiley & Sons, Ink.). Can be sought.
1 / Tg (K) = W ₁ / Tg ₁ + W ₂ / Tg ₂ + ... + W _n / Tg _n
W _n ; mass fraction Tg _{n of} each monomer; Tg (K) of the homopolymer of each monomer, and is a polymer handbook (3rd Ed., J. Brandrup and E.H. Immunogut, WILEY INTERSCIENCE). You can use the published value that is open to the public, such as the value inside. The same applies to the Tg of the second polymer portion described later.

The first polymer portion contained in the (meth) acrylic acid ester copolymer may be a homopolymer or a copolymer, and among them, a homopolymer can be used. The monomer component and the polymer component constituting the first polymer portion may be a monomer component and a polymer component capable of obtaining the first polymer portion having a Tg in a predetermined range, and may be, for example, acrylic. Acrylic acid ester monomers such as butyl acid, 2-ethylhexyl acrylate, isononyl acrylate, and methyl acrylate, other monomers such as vinyl acetate, acetal, and urethane, and polar group-containing singles containing the above-mentioned polar groups. Examples thereof include monomers and copolymers such as EVA.

The Tg of the second polymer portion contained in the (meth) acrylic acid ester copolymer is 20 ° C. or higher and is in the range of 20 ° C. or higher and 150 ° C. or lower, particularly in the range of 30 ° C. or higher and 150 ° C. or lower, particularly. It can be in the range of 40 ° C. or higher and 150 ° C. or lower.

Further, the second polymer portion contained in the (meth) acrylic acid ester copolymer may be a homopolymer or a copolymer, but among them, a homopolymer can be used. .. The monomer component constituting the second polymer portion may be any monomer component capable of obtaining the second polymer portion in which Tg is in a predetermined range, and is, for example, an acrylic acid ester simple such as methyl methacrylate. Polymers, other monomers such as acrylamide, styrene, vinyl chloride, amide, acrylonitrile, cellulose acetate, phenol, urethane, vinylidene chloride, methylene chloride, and methacrylonitrile, polar group-containing monomers including the above-mentioned polar groups The body is mentioned.

Specific examples of the (meth) acrylic acid ester copolymer having the first polymer portion and the second polymer portion include the above-mentioned MMA-BA-MMA copolymer and the like.

The mass average molecular weight of the second phase-soluble polymer component can be appropriately set according to the adhesiveness and cohesive force required for the first adhesive layer, and the mass average molecular weight of the second adhesive component, among others. It can be larger than the mass average molecular weight of the curable organic compound. This is because it is necessary for the curable organic compound to act as a plastic component, leaving the film-forming property to the second-phase soluble polymer component. Further, it is desirable that the second phase-soluble polymer component is compatible with the first adhesive component contained in the first adhesive composition. Specifically, the mass average molecular weight of the second phase-soluble polymer component can be in the range of 10,000 or more and 900,000 or less, and in particular, in the range of 30,000 or more and 500,000 or less. If the mass average molecular weight of the second phase-soluble polymer component is too small, three-dimensional cross-linking becomes dominant and the toughness may decrease, while if it is too large, the compatibility deteriorates and the strength decreases. The mass average molecular weight of the second phase-soluble polymer can be measured by GPC (eluent: THF, standard substance: PS, sample: 20 μL, flow rate: 1 mL / min, column temperature: 40 ° C.).

The content of the second phase-soluble polymer component in the first adhesive layer includes the type of the second phase-soluble polymer component, the type of the second adhesive component, the adhesiveness required for the first adhesive layer, and the cohesiveness. , It is possible to adjust appropriately according to the viscosity and the like. For example, when the first adhesive layer contains a curable organic compound such as an acrylic compound or an epoxy compound as a second adhesive component, and contains the above (meth) acrylic acid ester copolymer as a second phase-soluble polymer component. The content of the (meth) acrylic acid ester copolymer can be in the range of 4 parts by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the curable organic compound. When both are mixed at this ratio, the first adhesive layer develops a structure in which the acrylic polymer is dispersed in the curable organic compound in the form of fine particles at the nano-order level before the contact curing, which is an apparent phase. The dissolved state is expressed. Then, the first adhesive layer can exhibit excellent adhesive strength by being cured while maintaining an apparent compatible state by contact with the first adhesive composition. Further, since the first adhesive layer after curing has the above structure, it is possible to suppress the intrusion of water from the interface with the adherend, and it is possible to have further excellent adhesive holding characteristics.

Further, for example, when the first adhesive layer does not contain a curable organic compound or a curable inorganic material as the second adhesive component, the content of the second phase-soluble polymer component in the first adhesive layer is the first. It can be in the range of 10 parts by mass or more and 200 parts by mass or less, particularly in the range of 20 parts by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the second adhesive component in the adhesive layer. The suitable content varies depending on the molecular weight and the like of the second phase-soluble polymer component, but can be approximately within the above range. If the content of the second phase-soluble polymer component is too small, the film-forming property and adhesiveness of the first adhesive layer may be poor, while if the content is too large, the strength of the first adhesive layer may be poor. It may cause a decrease.

(3) Phase 1 Soluble Polymer Component The first adhesive composition can further contain a first phase compatible polymer component having compatibility with the first adhesive component. In addition, the first phase-compatible polymer component can further have compatibility with the second adhesive component contained in the first adhesive layer. The reason, specific examples of the first phase-soluble polymer component, and the content of the first phase-soluble polymer component are the same as those of the above-mentioned second phase-soluble polymer component, and thus the description thereof is omitted here. .. When the first adhesive composition or the first adhesive layer contains a curable organic compound of any of an epoxy compound, an acrylic compound, and a polyol compound as the first adhesive component or the second adhesive component, the first is described above. The effect of the compatible polymer component can be more exerted.

The mass average molecular weight of the first phase-soluble polymer component can be made larger than the mass average molecular weight of the first adhesive component, particularly the mass average molecular weight of the curable organic compound. The reason, the specific range of the mass average molecular weight, and the measuring method thereof are the same as those of the second phase-soluble polymer component described above, and thus the description thereof is omitted here.

The first phase-soluble polymer component contained in the first adhesive composition and the second phase-soluble polymer component contained in the first adhesive layer may be the same component or different components. good. This is because when the first phase-soluble polymer component and the second phase-soluble polymer component are the same component, the same component is most likely to undergo phase diffusion, which is advantageous in terms of reaction rate. It is also advantageous in terms of cost. When the first phase-soluble polymer component and the second phase-soluble polymer component are the same component, the same component including the acrylic polymer can be used. At this time, the acrylic polymer can be a (meth) acrylic acid ester copolymer, and among them, an acrylic copolymer or a modified product thereof, particularly an MMA-BA-MMA copolymer or a modified product thereof. be able to. Further, the acrylic polymer can be a (meth) acrylic acid ester copolymer having a predetermined first polymer portion and second polymer portion, or a modified product thereof. The reason is the same as the reason explained in the section of the second phase soluble polymer component described above.

When the first phase-soluble polymer component and the second phase-soluble polymer component are different components, the first phase-soluble polymer component and the second phase-soluble polymer component can be appropriately selected for adhesion. Since the physical properties of the first adhesive composition and the first adhesive layer can be adjusted according to the body, it is suitable for bonding dissimilar members.

When the first phase-soluble polymer component and the second phase-soluble polymer component are different components, the first phase-soluble weight depends on the functions required for the first adhesive composition and the first adhesive layer, respectively. The coalesced component and the second phase-soluble polymer component can be appropriately selected. For example, as described in the fifth and seventh embodiments of the method for producing an article described later, when the coating layer and the first adhesive layer of the first adhesive composition are laminated on the first member, the first member. The first adhesive composition on the side is required to have adhesive performance, and the first adhesive layer arranged on the outermost surface is required to have a protective function. In this case, the first adhesive layer is hardened by appropriately selecting the first phase-soluble polymer component and the second phase-soluble polymer component so that the first adhesive layer arranged on the outermost surface becomes harder after curing. Coatability can be imparted. Further, for example, as described in the sixth embodiment and the eighth embodiment of the method for producing an article described later, when the first adhesive layer and the coating layer of the first adhesive composition are laminated on the first member, the most The first adhesive composition is formed by appropriately selecting the first phase-soluble polymer component and the second phase-soluble polymer component so that the coating layer of the first adhesive composition arranged on the surface becomes harder after curing. It is possible to give a hard coat property to an object.

(4) Other Ingredients The first adhesive composition and the first adhesive layer also include inorganic particles such as silica and glass beads, a chain transfer agent, a flame retardant, a thickener, a heat radiating agent, an insulating agent, and a conductive agent. , Fibers for improving strength (particularly chopped fibers, etc.), tackifiers such as silicone compounds, antioxidants, reaction inhibitors, and other arbitrary components may be contained.

The first adhesive composition and the first adhesive layer may contain a colorant. For example, as described in the fifth and seventh embodiments of the method for producing an article described later, a case where a coating layer and a first adhesive layer of the first adhesive composition are laminated on a first member, or a case described later. When the first adhesive layer and the coating layer of the first adhesive composition are laminated on the first member as described in the sixth embodiment and the eighth embodiment of the method for producing the article, the first adhesive composition. Since at least one of the object and the first adhesive layer contains a colorant, visibility can be enhanced, it becomes easy to confirm the place where the adhesive set is applied, and the member to which the adhesive set is applied is protected. be able to. Examples of the colorant include pigments such as carbon black and dyes. Above all, the colorant can be a pigment. This is because by including the pigment as the colorant, the pigment can absorb ultraviolet rays and prevent the member from being deteriorated by ultraviolet rays.

Further, as described in the fifth and seventh embodiments of the method for producing an article described later, a case where a coating layer and a first adhesive layer of the first adhesive composition are laminated on the first member, or a case described later. When the first adhesive layer and the coating layer of the first adhesive composition are laminated on the first member as described in the sixth embodiment and the eighth embodiment of the method for producing the article, the first adhesive composition. At least one of the object and the first adhesive layer can contain, for example, a weather resistant agent such as an ultraviolet absorber, a hindered amine-based light stabilizer, and an infrared reflector. Thereby, it is possible to protect the member and suppress the deterioration of the first adhesive composition and the first adhesive layer after curing with time.

In addition, the first adhesive composition may contain a solvent, if necessary.

2. Properties The first adhesive composition and the first adhesive layer may be transparent or opaque, but can be transparent. This is because the components contained in the first adhesive composition and the first adhesive layer are sufficiently compatible with each other, and desired functions such as adhesiveness can be exhibited.

The first adhesive layer may or may not have adhesiveness before curing, but can have adhesiveness. Since photo-curing type and thermosetting type adhesives need to be cured until the curing is completed, the bonded state must be maintained by the desired curing time, pressing, etc. after the members are bonded via the above adhesive. Therefore, the work of the bonding process becomes complicated. On the other hand, since the first adhesive layer has adhesiveness, the adhesive force of the first adhesive layer enables curing and curing while maintaining the bonded state until the contact curing is completed. In the present specification, the "adhesiveness of the first adhesive layer" means the adhesiveness of the first adhesive layer before contact (before curing) unless there are special circumstances.

Here, "adhesiveness" is a concept included in "adhesiveness". Adhesion is sometimes used to mean a temporary adhesion phenomenon, while adhesion is sometimes used to mean a virtually permanent adhesion phenomenon (Iwanami Shoten, Physics and Chemistry Dictionary, 5th Edition). "Adhesiveness" and "adhesive strength" refer to the property of adhering by pressure sensitivity and the adhesive strength at that time. The fact that the first adhesive layer has adhesiveness means that the first adhesive layer before contact curing has an adhesive force (adhesive force) sufficient to temporarily fix the member. That is, the first adhesive layer before curing has a weaker adhesive force than after curing.

The adhesive strength of the first adhesive layer before contact (before curing) can be appropriately set according to the type of the first adhesive layer, the type of the adherend, and the arrangement mode. The adhesive force to the adherend of the first adhesive layer can be at least in the range of 0.05 N / inch or more and 50 N / inch or less, and in particular, in the range of 0.1 N / inch or more and 40 N / inch or less. Can be.

The first adhesive layer can be further classified into strong adhesiveness, medium adhesiveness, and weak adhesiveness according to the magnitude of adhesive strength. Specifically, the adhesive strength is strongly adhesive in the range of 5N / inch or more and 50N / inch or less, medium adhesive in the range of 1N / inch or more and less than 5N / inch, 0.05N / inch or more, 1N. The range of less than / inch can be weakly adhesive. Medium adhesiveness can be included in strong adhesiveness or weak adhesiveness depending on the application and physical characteristics. The adhesiveness of the first adhesive layer can be adjusted by adjusting the thickness, composition, and the like.

The stronger the adhesive force, the lower the cohesive force and the more flexible the first adhesive layer, while the weaker the adhesive force, the higher the cohesive force and the harder the layer. When the first adhesive layer is strongly adhesive, it is easy to adhere to the coating layer of the first adhesive composition, and the components contained in the first adhesive layer and the first adhesive component are easily transferred to each other. , The curing reaction by contact is easy to proceed, and it is possible to improve the reactivity. Further, when the first adhesive layer is weakly adhesive, the handleability of the first adhesive layer is improved, the workability can be improved, and even if the first adhesive layer is bonded once, even before the curing reaction is completed. For example, the coating layer of the first adhesive composition and the first adhesive layer can be peeled off and reattached on the adhesive surface, and the reworkability can be improved. Further, when the first adhesive layer is medium-adhesive, the reactivity, workability, and reworkability are all good.

The adhesive strength of the first adhesive layer to the adherend can be measured by the following method. The first adhesive sheet having no separator on both sides is measured after a separator (for example, PET separator PET28 × IJ0 manufactured by Nipper Co., Ltd.), which is a release film, is attached. First, the first adhesive sheet provided with separators on both sides of the first adhesive layer is cut into a size of 25.4 mm in length and 150 mm in width, one of the separators is peeled off, and PET is placed on the exposed first adhesive layer. The film (A4100 manufactured by Toyobo Co., Ltd.) is bonded using a manual roller. After that, the other separator is peeled off, and a SUS plate (304BA, adherent surface: polished surface, sample: 25.4 mm in length, 150 mm in width) is bonded to the exposed first adhesive layer using a manual roller. .. After that, the first adhesive layer with the PET film was peeled off by hand from the SUS plate by about 20 mm, and using a tensile tester (manufactured by A & D Co., Ltd., model number: RTF-1150H), JIS Z0237: 2009. (Adhesive tape / adhesive sheet test method) and method 1 of adhesive strength test method (temperature 23 ° C, humidity 50%, test method of peeling tape and sheet 180 ° to stainless steel test plate) (tensile) The adhesive strength (N / inch) to the SUS plate surface can be measured at a speed: 300 mm / min, a peeling distance: 150 mm, and a peeling angle: 180 °). In addition, 1 inch is 25.4 mm.

Here, the above-mentioned "at least" is an adhesive that can maintain the bonded state when the first adhesive layer is bonded to the adherend as long as it has the minimum range of adhesive strength. It means the range of force. Then, while the first adhesive layer has an adhesive force in this range, the adherend can be preferably bonded to the first adhesive layer.

Further, the coating layer of the first adhesive composition formed by applying the first adhesive composition to the adherend may or may not have adhesiveness before curing. , Can have adhesiveness. The reason is as described above.

The adhesive strength of the coating layer of the first adhesive composition to the adherend can be measured by the following method. First, the first adhesive composition is applied onto a SUS plate so that the dry coating amount is ^{about 50 g / m 2} , and after air-drying for at least 1 hour, a PET film is applied to the coated surface of the first adhesive composition. (For example, manufactured by Toyobo Co., Ltd., A4100, thickness 100 μm) is attached with a rubber roller. Then, a notch having a width of 25 mm and a length of 200 mm is made, and the end portion of the PET film is peeled off by about 50 mm. A tensile tester (Digital Force Gauge ZTS manufactured by Imada Co., Ltd.) is attached to the end of the peeled PET film, and the film is peeled under the conditions of a tensile speed of 200 mm / min and a peeling angle of 90 °. The maximum point stress at that time is taken as the adhesive force of the coating layer of the first adhesive composition.

Further, the first adhesive composition and the first adhesive layer become a cured adhesive layer by contact curing. The cured adhesive layer will be described later.

B. First Adhesive Sheet The first adhesive sheet may have a first adhesive layer, but may have a first separator arranged on at least one surface side of the first adhesive layer.

1. 1. First Adhesive Layer When the first adhesive layer is provided on at least one surface side of the separator, for example, it may be provided on the entire surface on at least one surface side of the separator, or may be provided in a pattern. good.

When the first adhesive layer is provided on the entire surface on at least one surface side of the separator, as illustrated in FIGS. 3 (a) and 3 (b), a notch that cuts the first adhesive layer 24 in the thickness direction. It may have a portion 25 and may have a plurality of first adhesive portions 24a defined by the notch portion 25. In this case, when the first member and the second member are bonded using the adhesive set, the second member 2 is previously attached to each of the first adhesive portions 24a as illustrated in FIG. 4 (b). At the same time, the member 30 with the first adhesive sheet can be prepared. Since the first adhesive sheet has good position accuracy and thickness accuracy, the second member and the first adhesive portion can be bonded with high accuracy. Further, since the curing reaction of the first adhesive layer does not proceed until it comes into contact with the first adhesive composition, a member with a first adhesive sheet can be prepared in advance and stored for a long period of time before the bonding process. A member with a first adhesive sheet can be used depending on the timing of bonding the members. Note that FIG. 3B is a cross-sectional view taken along the line AA of FIG. 3A. Further, FIG. 4 will be described later.

In the above case, the first adhesive layer is cut in the thickness direction by the cut portion, and the plurality of first adhesive portions are each defined by the cut portion. The size and shape of the first adhesive portion defined by the cut portion are appropriately adjusted according to the size and shape of the adherend surface of the adherend.

Further, in the above case, the separator is arranged on at least one surface side of the first adhesive layer. When the separator is arranged on one side of the first adhesive layer, the first adhesive layer is cut in the thickness direction by the cut portion, but the separator can be prevented from being cut. Further, when the separators are arranged on both sides of the first adhesive layer, one separator can be prevented from being cut, and the other separator can be cut at the same position as the first adhesive layer in the thickness direction. Well, it doesn't have to be cut.

Further, as illustrated in FIGS. 5A and 5B, the first adhesive layer has a pattern when the first adhesive layer 24 is provided in a pattern on at least one surface side of the separator 23. It can have a plurality of second adhesive portions 24b. Also in this case, when the first member and the second member are bonded using the adhesive set, the second member 2 is previously attached to each of the second adhesive portions 24b as illustrated in FIG. 6 (b). At the same time, the member 30 with the first adhesive sheet can be prepared. Therefore, it has the same advantages as the above case. Note that FIG. 5B is a cross-sectional view taken along the line AA of FIG. 5A. Further, FIG. 6 will be described later.

Here, the pattern shape means a state in which a portion provided with the first adhesive layer and a portion not provided with the first adhesive layer are provided on at least one surface side of the separator.

In the above case, the size and shape of the second adhesive portion are appropriately adjusted according to the size and shape of the adherend surface of the adherend.

The thickness of the first adhesive layer can be appropriately set according to the type of adherend and the like, and contains each component in an amount required for a curing reaction by contact between the first adhesive composition and the first adhesive layer. Can be made possible. Specifically, the thickness of the first adhesive layer can be 2 μm or more, particularly 5 μm or more, particularly 10 μm or more, and further 20 μm or more. Further, the thickness can be 200 μm or less, particularly 150 μm or less, particularly 100 μm or less.

Further, when the adherend surface of the adherend is a rough surface, the thickness of the first adhesive layer can be increased, and specifically, the thickness should be equal to or greater than the height difference of the unevenness of the adherend surface. Can be done. If the first adhesive layer does not have a thickness equal to or greater than the height difference of the unevenness of the adherend surface, the first adhesive layer cannot follow the unevenness and the adhesive area between the first adhesive layer and the adherend surface becomes small. Therefore, the adherend cannot be held for a desired period of time.

2. Separator The separator is not particularly limited as long as it can be peeled off from the first adhesive layer, and can have enough strength to protect the first adhesive layer. As such a separator, conventionally known ones such as a release film, a separate paper, a separate film, a separate paper, a release film, and a release paper can be used. Specific examples thereof include polypropylene, polyethylene and fluorine films. Further, the separator may be a single layer exemplified above and has releasability, but the releasable layer is formed on one side or both sides of a base material for releasable paper such as high-quality paper, coated paper, impregnated paper, and plastic film. You may use the laminated body which formed. The release layer is not particularly limited as long as it is a material having releasability, and for example, a silicone compound, an organic compound modified silicone compound, a fluorine compound, an aminoalkide compound, a melamine compound, an acrylic compound, a polyester compound, and a long-chain alkyl. There are compounds and the like. These compounds can be emulsion type, solvent type or solvent-free type.

When the adherend surface of the adherend is a rough surface, the separator can have flexibility. This is because when the first adhesive sheet is attached to the adherend, the separator can also follow the elongation of the first adhesive layer. Examples of such a separator include a PE film and the like.

The separator may have a light-shielding property depending on the type of material contained in the first adhesive layer and the construction environment in which the adherend is bonded. This is because it is possible to prevent the first adhesive layer from being deteriorated by being irradiated with ultraviolet rays or the like before the bonding step. Examples of the separator having a light-shielding property include an aluminum foil separator, an aluminum-deposited film, a paper separator, a colored separator, and a film separator containing an ultraviolet absorber.

Further, the separator may be easily peeled off on the surface in contact with the first adhesive layer.

The first adhesive sheet before being attached to the adherend may have separators on both sides of the first adhesive layer. When the separators are provided on both sides of the first adhesive layer, the separators arranged on each surface may be the same or different, but one may have light peelability and the other may have heavy peelability. can.

3. 3. First Adhesive Sheet The first adhesive sheet may be single-wafered or may be long.

The first adhesive sheet is, for example, one of two types of liquid materials such as a two-component separate coating type adhesive, specifically, an adhesive composition containing a second adhesive component is applied to one side of a separator and dried. Can be formed with. The adhesive composition may contain a solvent, if desired.

The method of applying the adhesive composition is not particularly limited, and a known printing method or coating method can be used. When the first adhesive layer is formed in a pattern on one side of the separator, the adhesive composition may be applied in a pattern on one side of the separator. The coating method is not particularly limited, and a known printing method or coating method can be used. Further, the drying condition of the coating layer can be carried out under such a condition that the solvent contained in the coating layer can be sufficiently volatilized, and can be appropriately set according to the composition.

When forming a cut portion in the first adhesive layer, for example, half-cut processing, pinhole processing, laser processing, or the like can be used as the method for forming the cut portion. When the separators are arranged on both sides of the first adhesive layer, the first adhesive layer is formed after the first adhesive layer is formed on one side of one separator and before the other separator is arranged on the first adhesive layer. A cut portion may be formed in, a first adhesive layer is formed on one side of one separator, the other separator is placed on the first adhesive layer, and then the cut is made in the first adhesive layer and the other separator. Part may be formed. Further, after forming the cut portion in the first adhesive layer, the first adhesive layer is provided in a pattern on one side of the separator by removing the portions other than the plurality of first adhesive portions defined by the cut portion. You can also do it.

The first adhesive sheet is obtained by applying an adhesive composition to one side of a separator and drying it to form a first adhesive layer, and then arranging another separator on the first adhesive layer to form both sides of the first adhesive layer. It is also possible to have a separator in the.

C. Adhesive set The adhesive set may have a liquid first adhesive composition and a first adhesive sheet provided with a first adhesive layer, but may further include, for example, a liquid second adhesive composition. Or may further have a second adhesive sheet with a second adhesive layer.

When the adhesive set has a liquid first adhesive composition, a liquid second adhesive composition, and a first adhesive sheet provided with a first adhesive layer, the liquid second adhesive composition is the first. The first adhesive composition, the second adhesive composition, and the first adhesive sheet contain the three adhesive components, and are contained in the first adhesive component and the first adhesive layer contained in the first adhesive composition. The second adhesive components are configured to be cured and adhered by contacting each other, and the third adhesive component contained in the second adhesive composition and the second adhesive component contained in the first adhesive layer are contained. It is configured to cure and adhere when in contact with each other. The third adhesive component can be the same as the first adhesive component, and the second adhesive composition can be the same as the first adhesive composition.

Further, when the adhesive set has a liquid first adhesive composition, a first adhesive sheet including the first adhesive layer, and a second adhesive sheet including the second adhesive layer, the second adhesive layer is the second. 4 The adhesive component is contained, and the first adhesive composition, the first adhesive sheet and the second adhesive sheet are the first adhesive component contained in the first adhesive composition and the first adhesive layer contained in the first adhesive layer. The two adhesive components are configured to be cured and adhered by contacting each other, and the first adhesive component contained in the first adhesive composition and the fourth adhesive component contained in the second adhesive layer are in contact with each other. By doing so, it is configured to be cured and adhered. The fourth adhesive component can be the same as the second adhesive component, and the components and configurations of the second adhesive sheet other than the fourth adhesive component can be the same as those of the first adhesive sheet. ..

II. Manufacturing Method of Article Next, a manufacturing method of the article of the present disclosure will be described. In the method for producing the article of the present disclosure, the above-mentioned adhesive set can be used. Since the adhesive set has been described in detail in "I. Adhesive set" above, the description thereof will be omitted here.

The manufacturing method of the article of the present disclosure is roughly classified into eight embodiments. Hereinafter, each embodiment will be described separately.

A. First Embodiment of the Article Manufacturing Method The first embodiment of the article manufacturing method uses a liquid first adhesive composition and a first adhesive sheet having a first adhesive layer, and uses a first member and a second. A method for manufacturing an article in which members are bonded together, wherein the first member is coated with the first adhesive composition, and the second member is coated with the first adhesive layer of the first adhesive sheet. A preparatory step for preparing a member with a first adhesive sheet to which one surface is bonded, a coated surface of the first adhesive composition of the first member, and the first member of the first member with an adhesive sheet. The first adhesive composition contains a first adhesive component, and the first adhesive layer contains a second adhesive component. The first adhesive composition and the first adhesive sheet are configured so that the first adhesive component and the second adhesive component are cured and adhered by contacting each other.

FIG. 2 is a process diagram showing an example of the first embodiment of the method for manufacturing an article. As illustrated in FIG. 2, first, the first adhesive composition 22 is applied to the first member 1 (FIG. 2 (a), coating step). Further, separately, the member 30 with the first adhesive sheet is prepared (FIG. 2B, preparation step). The member 30 with the first adhesive sheet is formed by bonding one surface of the first adhesive layer 24 of the first adhesive sheet 12 to the second member 2. As shown in FIG. 2B, the first adhesive sheet 12 may have a separator 23 arranged on at least one surface side of the first adhesive layer 24. Subsequently, the coated surface of the first adhesive composition 22 of the first member 1 and the other surface of the first adhesive layer 24 of the member 30 with the first adhesive sheet are bonded together (FIGS. 2C to 2d). ), Laminating process). When the member 30 with the first adhesive sheet has the separator 23 on the other surface of the first adhesive layer 24, the separator 23 is peeled off and bonded. At this time, when the first adhesive composition 22 and the first adhesive layer 24 come into contact with each other, the components in the first adhesive composition 22 and the components in the first adhesive layer 24 diffuse with each other, and the first adhesive When the first adhesive component contained in the composition 22 and the second adhesive component contained in the first adhesive layer 24 come into contact with each other, a curing reaction occurs and the adhesiveness is improved. When the curing reaction is completed, the first adhesive composition 22 and the first adhesive layer 24 become a cured adhesive layer 3 exhibiting a strong adhesive force (FIG. 2 (d)), and the first adhesive layer 3 is passed through the cured adhesive layer 3. The member 1 and the second member 2 can be firmly bonded to each other. As a result, the article 10 having the first member 1, the cured adhesive layer 3, and the second member 2 is obtained.

According to the first embodiment of the method for manufacturing an article, the coated surface of the first adhesive composition of the first member and the first adhesive layer of the member with the first adhesive sheet are bonded to each other to cause a curing reaction by contact. The members can be bonded to each other with a strong adhesive force developed by curing. Further, in the member with the first adhesive sheet, since the first adhesive sheet is bonded to the second member, it is not necessary to mix the two liquids as in the case of the two-component adhesive, and the members can be easily bonded to each other. It is possible to do. In addition, the thickness of the first adhesive layer can be controlled, and problems such as uneven application of the adhesive, forgetting to apply the adhesive, and protrusion from the adherend surface can be suppressed. Furthermore, since the curing reaction of the first adhesive layer does not proceed until it comes into contact with the first adhesive composition, it can be separately stored for a long period of time as a member with the first adhesive sheet until before the bonding process. The first adhesive layer of the member with the first adhesive sheet can be brought into contact with the first adhesive composition depending on the timing of bonding. In this way, by forming one of the two types of liquid materials of the two-component separate coating type adhesive into a sheet, it is possible to simplify the production of the article as compared with the coating bonding method.

Further, the method for manufacturing the article of the present embodiment includes the types of the first member and the second member, the direction of the adherend surface (adhesive surface) when the members are bonded to each other, the first adhesive composition and the first. Construction is possible according to the degree of adhesiveness of the adhesive layer. Hereinafter, a construction example using the method for manufacturing the article of the present embodiment will be described with reference to an example.

The first example of the construction example using the method for manufacturing the article of the present embodiment is a construction example in which the adherend surface (adhesive surface) of the first member and the second member is a vertical surface or a normal surface. In the example shown in FIG. 7, the adherend surface of the second member 2 is a vertical surface. The reference numerals in FIG. 7 are the same as those in FIG. 2.

In the above example, the adherend surface is within the range of −45 degrees or more and +45 degrees or less, especially within the range of -30 degrees or more and +30 degrees or less, particularly -15 degrees or more and +15 degrees with respect to the vertical plane or the normal plane. It can be within the following range. In the case of the adherent surface, when the coated surface of the first adhesive composition on the surface of the first member and the first adhesive layer on the surface of the second member are bonded in the bonding step, the surface is in the vertical direction or the normal direction. Shear stress is applied. However, since the coating layer and the first adhesive layer of the first adhesive composition have desired adhesive force and cohesive force, respectively, the curing reaction due to the contact between the first adhesive composition and the first adhesive layer proceeds sufficiently. It is possible to maintain the bonded state of the first member and the second member until a sufficient adhesive force is exhibited, and it is possible to suppress the peeling of the members due to the application of shear stress. Further, even if the adhesive force decreases with time, the strong adhesive force developed by the progress of the curing reaction during that period makes it possible to firmly adhere and hold the first member and the second member. Further, by adjusting the adhesive force between the coating layer and the first adhesive layer of the first adhesive composition, if the first adhesive composition and the first adhesive layer are not cured, they can be reattached after the bonding. It will be possible. Further, by making the coating layer and the first adhesive layer of the first adhesive composition highly viscous or low viscosity, it is possible to translate the first adhesive composition with respect to the adherend surface in a bonded state, and the position can be adjusted. Become.

The second example of the construction example using the method for manufacturing the article of the present embodiment is a construction example in which the adherend surface (adhesive surface) of the first member and the second member is a horizontal plane. In the example shown in FIG. 8, the adherend surface of the second member 2 is a horizontal plane. The reference numerals in FIG. 8 are the same as those in FIG. 2.

In the above example, the adherend surface is within the range of −45 degrees or more and +45 degrees or less, particularly within the range of -30 degrees or more and +30 degrees or less, and particularly within the range of -15 degrees or more and +15 degrees or less. can do. In the case of the adherend surface, the coating layer and the first adhesive layer of the first adhesive composition have desired adhesive force and cohesive force, respectively, so that the first adhesive composition and the first adhesive layer are cured by contact. The bonded state of the first member and the second member can be maintained until the reaction proceeds. Further, since the first member and the second member are firmly adhered to each other after curing, it is possible to prevent the first member and the second member from being displaced even if they are subjected to shear stress in the horizontal direction. Further, by adjusting the adhesive force between the coating layer and the first adhesive layer of the first adhesive composition, if the first adhesive composition and the first adhesive layer are not cured, they can be reattached after the bonding. It will be possible. Further, by making the coating layer and the first adhesive layer of the first adhesive composition highly viscous or low viscosity, it is possible to translate the first adhesive composition with respect to the adherend surface in a bonded state, and the position can be adjusted. Become.

Further, since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet can be appropriately selected according to the type of the member in consideration of suitability. Therefore, for example, it is useful when the first member and the second member are different kinds of members, or when the first member has an uneven surface or a porous surface.

Further, since the first adhesive composition is liquid, the first adhesive component contained in the first adhesive composition when the first adhesive composition and the first adhesive layer of the first adhesive sheet come into contact with each other. And the second adhesive component contained in the first adhesive layer can be easily diffused, and the reactivity can be enhanced.

Hereinafter, each step in the first embodiment of the method for manufacturing an article, and the first member and the second member will be described.

1. 1. Coating Step The coating step in the first embodiment of the method for manufacturing an article is a step of applying the first adhesive composition to the first member.

The method for applying the first adhesive composition is not particularly limited, and a known printing method or coating method can be used. Further, after applying the first adhesive composition, it may be dried. The drying conditions can be set to such an extent that the solvent contained in the first adhesive composition can be sufficiently volatilized, and can be appropriately set according to the composition.

The first adhesive composition may be solidly applied to the first member or may be applied in a pattern. Above all, from the viewpoint of workability, solid coating can be applied.

Further, the size of the region to which the first adhesive composition is applied may be the same as or larger than the size of the adherend surface of the first adhesive layer in the bonding step described later. Above all, since the first adhesive composition is inferior in position accuracy as compared with the first adhesive layer, the size of the region to which the first adhesive composition is applied is the size of the adherend surface of the first adhesive layer. It can be larger than that. In particular, as shown in FIGS. 4 and 6, for example, when the first member 1 is larger than the second member 2, the size of the region to which the first adhesive composition is applied is determined by the cover of the first adhesive layer. It can be larger than the size of the landing surface. In this case, as illustrated in FIGS. 4 (e) and 6 (e), the first adhesive layer of the first adhesive composition 22 (the first adhesive portion 24a in FIG. 4 and the second adhesive portion 24b in FIG. 6). The portion that does not come into contact with) does not become the cured adhesive layer 3, but it is considered that the portion does not come into contact with time.

Further, as described in the above-mentioned "I. Adhesive set", the coating layer of the first adhesive composition may or may not have adhesiveness before curing, but is adhesive. Can have sex.

The thickness of the coating layer of the first adhesive composition can be appropriately set according to the type of the member and the like. Specifically, the thickness of the coating layer of the first adhesive composition can be 2 μm or more, particularly 5 μm or more, particularly 20 μm or more. Further, the thickness can be 200 μm or less, particularly 150 μm or less, particularly 100 μm or less.

Further, the thicknesses of the coating layer and the first adhesive layer of the first adhesive composition may be the same or different.

2. Preparation step In the preparation step in the first embodiment of the method for manufacturing an article, a member with a first adhesive sheet is prepared, in which one surface of the first adhesive layer of the first adhesive sheet is bonded to the second member. It is a process.

The coating step and the preparatory step can be performed in any order, but the preparatory step can be performed first. Since the curing reaction of the first adhesive layer does not proceed until it comes into contact with the first adhesive composition, a member with a first adhesive sheet can be prepared in advance and stored for a long period of time before the bonding process. A member with a first adhesive sheet can be used depending on the timing of bonding the member and the second member.

The member with the first adhesive sheet may be one in which one second member is bonded to one surface of the first adhesive layer of the first adhesive sheet, and the member of the first adhesive layer of the first adhesive sheet. It may be a member with a multi-imposition first adhesive sheet in which a plurality of second members are bonded to one surface.

In the preparatory step, a member with a first adhesive sheet to which the first adhesive sheet is previously bonded to the second member may be prepared. This is because by using the ready-made member with the first adhesive sheet, it is not necessary to manufacture the member with the first adhesive sheet when manufacturing the article, and the time can be shortened.

Further, in the preparatory step, a first adhesive sheet having a separator and a first adhesive layer provided on at least one surface side of the separator is used, and the surface of the first adhesive layer on which the separator is not arranged is used as a second member. It may have a first adhesive sheet bonding step of bonding to.

When the preparatory step includes a first adhesive sheet bonding step, the first adhesive layer of the first adhesive sheet has a cut portion for cutting the first adhesive layer in the thickness direction, and is defined by the cut portion. 1 It may have an adhesive portion. In this case, in the first adhesive sheet bonding step, the second member can be bonded to one surface of the first adhesive portion. In this case, the first adhesive layer of the first adhesive sheet may have one first adhesive portion, and a plurality of first adhesive portions 24a are provided as illustrated in FIGS. 3A and 3B. You may have. When the first adhesive layer has a plurality of first adhesive portions, in the first adhesive sheet bonding step, as illustrated in FIG. 4B, a plurality of first adhesive portions 24a are formed on one surface of the plurality of first adhesive portions 24a. The second member 2 can be bonded to each other. Since the first adhesive layer has good position accuracy and thickness accuracy, the second member and the first adhesive portion can be bonded with high accuracy.

When the preparatory step includes the first adhesive sheet bonding step, in the first adhesive sheet bonding step, a plurality of second members are bonded to one surface of the first adhesive layer, and the multi-imposition first bonding is performed. Sheets may be made.

Further, when the preparation step includes the first adhesive sheet bonding step, the first adhesive layer of the first adhesive sheet may have a patterned second adhesive portion. In this case, in the first adhesive sheet bonding step, the second member can be bonded to one surface of the second adhesive portion. In this case, the first adhesive layer of the first adhesive sheet may have one second adhesive portion, and a plurality of second adhesive portions 24b are provided as illustrated in FIGS. 5A and 5B. You may have. When the first adhesive layer has a plurality of second adhesive portions, in the first adhesive sheet bonding step, as illustrated in FIG. 6B, a plurality of second adhesive portions 24b are formed on one surface of the plurality of second adhesive portions 24b. The second member 2 can be bonded to each other. Since the first adhesive layer has good position accuracy and thickness accuracy, the second member and the second adhesive portion can be bonded with high accuracy.

The method of bonding the second member and the first adhesive sheet can be appropriately selected depending on the form of the first adhesive sheet. When a first adhesive sheet in which a separator is arranged on one side of the first adhesive layer is used, for example, a first adhesive sheet roll wound in a roll shape with the first adhesive layer as a winding inner surface is used. A required amount can be unwound from the adhesive sheet roll, the first adhesive layer side can be arranged on the second member, and then cut and bonded. When the first adhesive sheet in which the separators are arranged on both sides of the first adhesive layer is used, one of the separators of the first adhesive sheet is peeled off by using the single-wafered first adhesive sheet and the first adhesive is attached. The layer can be exposed and a second member can be laminated onto it.

In the first adhesive sheet bonding step, the first adhesive sheet may be bonded to the entire contact surface of the second member, or may be bonded to the peripheral edge of the contact surface of the second member in a frame shape. When the first adhesive sheet is bonded, a squeegee or the like can be used to prevent air bubbles from entering the adhesive surface between the second member and the first adhesive layer of the first adhesive sheet.

In the first adhesive sheet bonding step, if the first adhesive layer has adhesiveness, it may be bonded by heat-pressing with an iron or the like, or by pressing with a roller while applying light vibration to bond. You may. The first adhesive layer can easily enter the gap between the second members, and the bonding strength between the first adhesive sheet and the second member can be increased.

Further, in the first adhesive sheet bonding step, when the first adhesive layer of the first adhesive sheet has a predetermined adhesive force, it is possible to have a positioning step of determining the bonding position of the first member. In the preparatory step, the first adhesive sheet is placed on the second member so that the first adhesive layer exhibits a desired adhesive force so that the bonding position of the first member becomes a desired position when the bonding process is performed. This is because it can be re-pasted. For example, if the first adhesive layer of the first adhesive sheet exhibits a desired adhesive force, the preparatory step includes both a first adhesive sheet bonding step and a positioning step of determining the bonding position of the first member. be able to. At this time, the second member to be bonded to the first adhesive sheet can be a fixing member.

3. 3. Bonding step The bonding step in the first embodiment of the method for manufacturing an article is the other of the coated surface of the first adhesive composition of the first member and the first adhesive layer of the member with the first adhesive sheet. It is a process of bonding with the surface of. In this step, the first adhesive composition and the first adhesive layer are cured by contacting each other, and the cured adhesive layer formed by contact curing can exhibit a strong adhesive force, and the members can exhibit strong adhesive force. Can be glued.

In the member with the first adhesive sheet, when the separator is arranged on the side opposite to the second member side of the first adhesive layer, the separator of the member with the first adhesive sheet is peeled off to expose the first adhesive layer. The surface and the coated surface of the first adhesive composition are bonded together.

The method of bonding the coated surface of the first adhesive composition of the first member to the first adhesive layer of the member with the first adhesive sheet is not particularly limited, and for example, the first member of the first member. A method can be used in which the coated surface of the adhesive composition and the first adhesive layer of the member with the first adhesive sheet are opposed to each other and bonded from directly above. Further, as another bonding method, the coated surface of the first adhesive composition of the first member and the first adhesive layer of the member with the first adhesive sheet face each other, and one of them is attached to the other surface. On the other hand, it can be attached by sliding it in the parallel direction. The above bonding method is suitable when the bonding surface between the first member and the second member is a horizontal plane.

When the member with the first adhesive sheet is a member with a multi-imposed first adhesive sheet, a portion having one second member is cut out from the multi-imposed first adhesive sheet member, and the first adhesive of the first member is used. It can be adhered to the coated surface of the composition.

Further, in the preparatory step, the separator 23 is arranged on one side of the first adhesive layer 24 as illustrated in FIGS. 3A and 3B, and the first adhesive layer 24 makes the first adhesive layer 24 thicker. A first adhesive sheet 12 having a notch portion 25 to be cut into the above and having a first adhesive portion 24a defined by the notch portion 25 is used, and as illustrated in FIG. 4 (b), of the first adhesive portion 24a. When the first adhesive sheet bonding step of bonding the second member 2 to the surface on which the separator 23 is not arranged is provided, in the bonding step, as illustrated in FIGS. 4 (c) to 4 (e), the first The first adhesive portion 24a on which the first adhesive portion 24a and the second member 2 are laminated in this order is peeled off from the separator 23 of the adhesive sheet attached member 30, and the first adhesive portion 24a of the first adhesive portion attached member 31 is peeled off. Can be attached to the coated surface of the first adhesive composition 22 of the first member 1. In this case, the first adhesive layer of the first adhesive sheet may have one first adhesive portion or may have a plurality of first adhesive portions.

Further, in the preparatory step, the separator 23 is arranged on one side of the first adhesive layer 24 as illustrated in FIGS. 5A and 5B, and the first adhesive layer 24 forms a patterned second adhesive portion 24b. It has a first adhesive sheet bonding step of bonding the second member 2 to the surface of the second adhesive portion 24b where the separator 23 is not arranged, as illustrated in FIG. 6 (b). In the case, in the bonding step, as illustrated in FIGS. 6C to 6E, the second adhesive portion 24a and the second member 2 are laminated in order from the separator 23 of the member 30 with the first adhesive sheet. 2 The member with the adhesive portion 32 can be peeled off, and the surface of the second adhesive portion 24b of the member with the second adhesive portion 32 can be attached to the coated surface of the first adhesive composition 22 of the first member 1. In this case, the first adhesive layer of the first adhesive sheet may have one second adhesive portion or may have a plurality of second adhesive portions.

In this step, the first member to which the first adhesive composition is applied and the member with the first adhesive sheet are attached according to the strength of the adhesive force between the coating layer of the first adhesive composition and the first adhesive layer. At that time, it may have a positioning step of reattaching and positioning one of them.

The first adhesive composition and the first adhesive layer can undergo a curing reaction by contact. The curing temperature of the first adhesive composition and the first adhesive layer can include normal temperature, and can be set, for example, in the range of 5 ° C. or higher and 180 ° C. or lower. The normal temperature means 23 ° C. Since the curing temperature includes normal temperature, it is possible to eliminate the need for heating and cooling, so that the production of the article can be simplified.

Further, the first adhesive composition and the first adhesive layer may be heated in a contact state to accelerate curing. The heating temperature can be appropriately set according to the composition of the first adhesive composition and the first adhesive layer, and can be, for example, in the range of 30 ° C. or higher and 120 ° C. or lower, particularly 40 ° C. or higher and 80 ° C. or higher. It can be within the range of ° C or lower. If the heating temperature is too high, the flowability of the first adhesive composition and the first adhesive layer will increase, and the adhesive will squeeze out from the adherend surface, and curing will proceed in the protruding state, causing poor appearance. This is because it may become. Further, depending on the first adhesive composition such as a small molecule monomer component and the components contained in the first adhesive layer, an odor is generated at a high temperature. On the other hand, if the heating temperature is too low, the curing promoting effect cannot be obtained so much, and it may be difficult to shorten the process time.

In addition, the first adhesive composition and the first adhesive layer can be cured for a desired time after being bonded. This is because the components contained in the first adhesive composition and the components contained in the first adhesive layer are diffused, and when they are sufficiently cured, a strong adhesive force can be exhibited. The curing time can be appropriately set according to the composition of the first adhesive composition and the first adhesive layer, and can be, for example, in the range of 0.5 hours or more and 72 hours or less. If the curing time is too short, it will not be possible to redo the bonding, while if the curing time is too long, the process time will increase.

The first adhesive composition and the first adhesive layer become a cured adhesive layer when the curing reaction by contact is completed. The cured adhesive layer is a cured product layer formed by reacting and curing the first adhesive component and the second adhesive component contained in the first adhesive composition and the first adhesive layer, respectively. The cured adhesive layer may be a single layer, or the contact interface between the first adhesive composition and the first adhesive layer may remain.

The hardened adhesive layer can firmly bond the first member and the second member with its strong adhesive force, and can have an adhesive force capable of holding the state for a long time. Among them, the shear tensile strength is increased. Can be high. This is because even when shear stress is applied over time, the first member and the second member can be held fixed for a long period of time, and peeling of the members can be suppressed.

4. First member and second member The first member and the second member may be the same type of member or different types of members. Since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet can be appropriately selected depending on the member in consideration of suitability. Therefore, it is useful when the first member and the second member are different types of members. Further, even when the first member and the second member are members of the same type, it is useful when the first member has an uneven surface or a porous surface.

Examples of different types of members include members having different materials, properties, properties, functions, forms, and the like. When the materials of the first member and the second member are different, the combinations of different materials include, for example, a combination of a metal material and an organic material, a combination of a metal material and a concrete material, a combination of a metal material and a ceramic material, and a concrete material. And organic materials, ceramic materials and organic materials, organic materials and wood, organic materials and cloths and leathers, dissimilar metal materials, dissimilar organic materials, etc. Be done. When the forms of the first member and the second member are different, examples of the combination of different forms include a combination of a molded product or a plate (board) and a film. Specifically, examples of the metal material include stainless steel, aluminum, copper and the like. Further, examples of the organic material include fiber reinforced composite materials (FRP) such as ABS, polyimide, polypropylene, carbon fiber reinforced composite material (CFRP) and glass fiber reinforced composite material (GFRP).

Among them, the material of the first member may be a concrete material, wood or fibrous material, and the material of the second member may be a metal material or an organic material. This is because when the material of the first member to which the first adhesive composition is applied is the above-mentioned material, the adhesive strength can be increased by the permeation of the first adhesive composition.

Further, the surface roughness of the first member is the surface of the second member, such that the adhered surface of the first member is a rough surface such as an uneven surface or a porous surface, and the adhered surface of the second member is a smooth surface. It may be larger than the roughness. When the surface roughness of the first member to which the first adhesive composition is applied is large, the first adhesive composition follows the irregularities and holes of the adherend surface of the first member to increase the adhesive strength. Because it can be enhanced.

B. Second Embodiment of the Article Manufacturing Method The second embodiment of the article manufacturing method uses a liquid first adhesive composition and a first adhesive sheet having a first adhesive layer, and uses a first member and a second. A method for manufacturing an article in which members are bonded together, wherein the first member is coated with the first adhesive composition, and the first member is coated with the first adhesive composition. The first adhesive sheet bonding step of bonding one surface of the first adhesive layer of the first adhesive sheet and the second member are bonded to the other surface of the first adhesive layer of the first adhesive sheet. The first adhesive composition contains a first adhesive component, the first adhesive layer contains a second adhesive component, and the first adhesive composition comprises a second member bonding step. The object and the first adhesive sheet are configured so that the first adhesive component and the second adhesive component are cured and adhered by contacting each other.

FIG. 9 is a process diagram showing an example of the second embodiment of the method for manufacturing an article. As illustrated in FIG. 9, first, the first adhesive composition is applied to the first member 1 (FIG. 9 (a), coating step). Next, one surface of the first adhesive layer 24 of the first adhesive sheet 12 is attached to the coated surface of the first adhesive composition 22 of the first member 1 (FIG. 9 (b), the first adhesive sheet is attached. Joint process). As shown in FIG. 9B, the first adhesive sheet 12 may have a separator 23 arranged on at least one surface side of the first adhesive layer 24. The first adhesive component contained in the first adhesive composition 22 and the second adhesive component contained in the first adhesive layer 24 can be cured by coming into contact with each other. Next, the second member 2 is bonded to the other surface of the first adhesive layer 24 of the first adhesive sheet 12 (FIG. 9 (c), second member bonding step). When the separator 23 is arranged on the other surface of the first adhesive layer 24, the separator 23 is peeled off. In the second member bonding step, the first adhesive composition 22 and the first adhesive layer 24 become a cured adhesive layer 3 that has developed a strong adhesive force by completing the curing reaction by contact, and becomes a cured adhesive layer 3 via the cured adhesive layer 3. The first member 1 and the second member 2 can be firmly bonded to each other. As a result, the article 10 having the first member 1, the cured adhesive layer 3 and the second member 2 can be obtained. Note that P in FIG. 9C indicates a region (cured region) cured by contact between the first adhesive composition 22 and the first adhesive layer 24.

According to the second embodiment of the method for manufacturing an article, by adhering the coated surface of the first adhesive composition of the first member and the first adhesive layer of the first adhesive sheet, the curing reaction proceeds by contact. The members can be bonded to each other with the strong adhesive force developed by curing. Further, since the first adhesive sheet is laminated on the coated surface of the first adhesive composition of the first member, it is not necessary to mix the two liquids unlike the two-component adhesive, and the bonding can be performed. It can be done easily. In addition, since the first adhesive sheet is used, it is possible to control the thickness of the first adhesive layer, and it is possible to suppress the occurrence of problems such as uneven application of the adhesive, forgetting to apply the adhesive, and protrusion from the adherend surface. Furthermore, since the first adhesive layer is not provided on the second member side, the second member can be easily handled. In this way, by forming one of the two types of liquid materials of the two-component separate coating type adhesive into a sheet, it is possible to simplify the production of the article as compared with the coating bonding method.

Further, since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet can be appropriately selected according to the type of the member in consideration of suitability. Therefore, for example, it is useful when the first member and the second member are different kinds of members, or when the first member has an uneven surface or a porous surface.

Further, since the first adhesive composition is liquid, the first adhesive component contained in the first adhesive composition when the first adhesive composition and the first adhesive layer of the first adhesive sheet come into contact with each other. And the second adhesive component contained in the first adhesive layer can be easily diffused, and the reactivity can be enhanced.

Since the first member and the second member are the same as those in the first embodiment of the above-described method for manufacturing an article, the description thereof is omitted here. Hereinafter, each step in the method for manufacturing the article of the present embodiment will be described.

1. 1. Coating Step The coating step in the second embodiment of the method for manufacturing an article is a step of applying the first adhesive composition to the first member. Since the coating step is the same as the coating step of the first embodiment of the above-described method for manufacturing an article, the description thereof is omitted here.

2. First Adhesive Sheet Bonding Step In the first adhesive sheet bonding step in the second embodiment of the method for manufacturing an article, the first adhesive sheet is applied to the coated surface of the first adhesive composition of the first member. 1 This is a step of bonding one surface of the adhesive layer. In this step, the separator of the first adhesive sheet having the separator and the first adhesive layer provided on one side of the separator is not arranged on the coated surface of the first adhesive composition of the first member. It can be a step of laminating the surfaces.

By adjusting the adhesive force or the cohesive force, the first adhesive layer can be reattached when it is attached to the coated surface of the first adhesive composition of the first member, and the bonding step described later. In, the second member can be reattached. Further, by making the first adhesive layer low-viscosity or high-viscosity, when the second member is bonded to the first adhesive layer in the bonding step described later, it is applied to the adherend surface of the first adhesive layer. The second member can be slid and moved in the parallel direction to be bonded.

The method of bonding one surface of the first adhesive layer of the first adhesive sheet to the coated surface of the first adhesive composition of the first member is not particularly limited. For example, a separator is arranged on one side of the first adhesive layer, and a required amount is unwound from the first adhesive sheet roll using a first adhesive sheet roll wound in a roll shape with the first adhesive layer as a winding inner surface. A method of bonding the first adhesive layer to the coated surface of the first adhesive composition and then cutting the first adhesive layer can be used. Further, using a single-wafered first adhesive sheet in which separators are arranged on both sides of the first adhesive layer, one of the separators of the first adhesive sheet is peeled off, and the exposed first adhesive layer and the first adhesive layer are bonded. A method of bonding the coated surface of the agent composition to the coated surface can be used.

In this step, the first adhesive composition and the first adhesive layer undergo a curing reaction upon contact, but the curing can be prevented from being completed before the second member bonding step described later. This is because it becomes difficult to attach the second member to the first adhesive layer.

3. 3. Second member bonding step The second member bonding step in the second embodiment of the method for manufacturing an article is a step of bonding the second member to the other surface of the first adhesive layer of the first adhesive sheet. ..

The method of bonding the other surface of the first adhesive layer and the second member is not particularly limited. For example, the second member can be attached to the adherend surface of the first adhesive layer arranged on the first member from directly above. When the first adhesive layer exhibits low viscosity or high viscosity, one of the first member or the second member on which the first adhesive layer is arranged is fixed and the other member is fixed. It is possible to slide and move the members in the direction parallel to the adherend surface of the members to bond them together. Such a method of bonding by sliding movement is suitable when the bonding surface between the first member and the second member is a horizontal plane.

This step is performed within the curing time after the coated surface of the first adhesive composition and the first adhesive layer are bonded in the first adhesive sheet bonding step, so that the first adhesive composition and the first adhesive are bonded. The second member can be fixed by the adhesiveness of the first adhesive layer until the curing reaction by the contact of the layers is completed. Further, when the curing reaction is completed, the second member can be firmly fixed. In addition, the worker can perform other constructions during curing. Above all, this step can be performed within 0.5 hours after the first adhesive composition and the first adhesive layer come into contact with each other. This is because there is a concern that the adhesive strength to the second member will decrease as the curing progresses. Further, after the second member is attached to the other surface of the first adhesive layer, it may be heated to accelerate the curing reaction. The curing time, curing temperature, and heating temperature are the same as those described in the above-mentioned section "A. First embodiment of the method for producing an article".

In this step, when the curing reaction by contact between the first adhesive composition and the first adhesive layer is completed, the first adhesive composition and the first adhesive layer are firmly adhered to each other, and the first member and the second member A hardened adhesive layer is formed between the two. The details of the cured adhesive layer and the contents not described in the method for manufacturing the article of the present embodiment are the same as the contents described in the above-mentioned "A. First embodiment of the method for manufacturing the article".

C. Third Embodiment of the Article Manufacturing Method The third embodiment of the article manufacturing method uses a liquid first adhesive composition and a first adhesive sheet having a first adhesive layer, and uses a first member and a second. Preparation for preparing a member with a first adhesive sheet, which is a method for manufacturing an article to which the members are bonded, wherein one surface of the first adhesive layer of the first adhesive sheet is bonded to the second member. The step, the coating step of applying the first adhesive composition to the other surface of the first adhesive layer of the member with the first adhesive sheet, and the first adhesive composition of the member with the first adhesive sheet. The first member bonding step of bonding the first member to the coated surface of the object is provided, the first adhesive composition contains the first adhesive component, and the first adhesive layer is the second. The first adhesive composition and the first adhesive sheet contain an adhesive component, and are configured such that the first adhesive component and the second adhesive component are cured and adhered by contacting each other. ing.

FIG. 10 is a process diagram showing an example of the third embodiment of the method for manufacturing an article. As illustrated in FIG. 10, first, the member 30 with the first adhesive sheet is prepared (FIG. 10A, preparation step). The member 30 with the first adhesive sheet is formed by bonding one surface of the first adhesive layer 24 of the first adhesive sheet 12 having the first adhesive layer 24 to the second member 2. As shown in FIG. 10A, the first adhesive sheet 12 may have a first separator 23 arranged on at least one surface side of the first adhesive layer 24. Next, the first adhesive composition is applied to the other surface of the first adhesive layer 24 of the member 30 with the first adhesive sheet (FIG. 10 (b), coating step). When the separator 23 is arranged on the other surface of the first adhesive layer 24, the separator 23 is peeled off. The first adhesive component contained in the first adhesive composition 22 and the second adhesive component contained in the first adhesive layer 24 can be cured by coming into contact with each other. Next, the first member 1 is bonded to the coated surface of the first adhesive composition 22 of the member 30 with the first adhesive sheet (FIG. 10 (c), first member bonding step). In the first member bonding step, the first adhesive composition 22 and the first adhesive layer 24 become a cured adhesive layer 3 that has developed a strong adhesive force by completing the curing reaction by contact, and becomes a cured adhesive layer 3 via the cured adhesive layer 3. The first member 1 and the second member 2 can be firmly bonded to each other. As a result, the article 10 having the first member 1, the cured adhesive layer 3 and the second member 2 can be obtained. Note that P in FIG. 10C indicates a region (cured region) cured by contact between the first adhesive composition 22 and the first adhesive layer 24.

According to the third embodiment of the method for manufacturing an article, by applying the first adhesive composition on the first adhesive layer bonded to the second member, the curing reaction proceeds by contact and is expressed by curing. The members can be bonded to each other with a strong adhesive force. Further, since the first adhesive composition is applied and laminated on the first adhesive layer bonded to the second member, it is not necessary to mix the two liquids unlike the two-component adhesive, and the bonding can be performed. It can be done easily. In addition, since the first adhesive sheet is used, it is possible to control the thickness of the first adhesive layer, and it is possible to suppress the occurrence of problems such as uneven application of the adhesive, forgetting to apply the adhesive, and protrusion from the adherend surface. Furthermore, since the first adhesive composition is not applied to the first member side, the handling of the first member becomes easy. In this way, by forming one of the two types of liquid materials of the two-component separate coating type adhesive into a sheet, it is possible to simplify the production of the article as compared with the coating bonding method.

Further, since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet can be appropriately selected according to the type of the member in consideration of suitability. Therefore, for example, it is useful when the first member and the second member are different kinds of members, or when the first member has an uneven surface or a porous surface.

Further, since the first adhesive composition is liquid, the first adhesive component contained in the first adhesive composition when the first adhesive composition and the first adhesive layer of the first adhesive sheet come into contact with each other. And the second adhesive component contained in the first adhesive layer can be easily diffused, and the reactivity can be enhanced.

Since the first member and the second member are the same as those in the first embodiment of the above-described method for manufacturing an article, the description thereof is omitted here. Hereinafter, each step in the method for manufacturing the article of the present embodiment will be described.

2. Coating Step The coating step in the third embodiment of the method for manufacturing an article is a step of applying the first adhesive composition to the other surface of the first adhesive layer of the member with the first adhesive sheet. The coating method of the first adhesive composition and the coating layer of the first adhesive composition have been described in the above-mentioned section "A. First embodiment of the method for producing an article 2. Coating step". The description of is omitted.

The first adhesive composition is applied to the surface.

In the preparatory step, the separator 23 is arranged on one side of the first adhesive layer 24 as illustrated in FIGS. 3A and 3B, and the first adhesive layer 24 is arranged in the same manner as the preparatory step of the first embodiment. However, a second sheet 12 having a cut portion 25 for cutting the first adhesive layer 24 in the thickness direction and having a first adhesive portion 24a defined by the cut portion 25 is used, and is illustrated in FIG. 4 (b). When the first adhesive sheet bonding step of bonding the second member 2 to the surface on which the separator 23 of the first adhesive portion 24a is not arranged is provided, the coating process is as illustrated in FIG. 4 (c). After peeling off the first adhesive portion-attached member 31 in which the first adhesive portion 24a and the second member 2 are laminated in this order from the separator 23 of the first adhesive sheet-attached member 30, although not shown, the first adhesive portion is attached. The first adhesive composition can be applied to the surface of the second adhesive portion of the member.

Further, in the preparatory step, similarly to the preparatory step of the first embodiment, the separator 23 is arranged on one side of the first adhesive layer 24 as illustrated in FIGS. 5A and 5B, and the first adhesion is performed. A second member is used on the surface of the second adhesive portion 24b where the separator 23 is not arranged, as illustrated in FIG. 6B, using the first adhesive sheet 12 in which the layer 24 has the second adhesive portion 24b in a pattern. When the first adhesive sheet bonding step of bonding 2 is provided, in the coating process, as illustrated in FIG. 6C, the separator 23 of the member 30 with the first adhesive sheet, the second adhesive portion 24b, and the second adhesive sheet are attached. After peeling off the member 32 with the second adhesive portion on which the members 2 are laminated in order, the first adhesive composition can be applied to the surface of the second adhesive portion of the member with the second adhesive portion (not shown).

In this step, the first adhesive composition and the first adhesive layer undergo a curing reaction upon contact, but the curing can be prevented from being completed before the first member bonding step described later. This is because it becomes difficult to attach the first member to the coated surface of the first adhesive composition.

3. 3. First member bonding step In the first member bonding step in the third embodiment of the method for manufacturing an article, the first member is bonded to the coated surface of the first adhesive composition of the member with the first adhesive sheet. It is a process.

The method of bonding the coated surface of the first adhesive composition of the member with the first adhesive sheet and the first member is not particularly limited. For example, the first member can be attached to the coated surface of the first adhesive composition arranged on the second member from directly above.

This step is performed within the curing time after applying the first adhesive composition to the other surface of the first adhesive layer in the coating step, so that the first adhesive composition and the first adhesive layer come into contact with each other. Until the curing reaction is completed, the first member can be fixed by the adhesiveness of the coating layer of the first adhesive composition. Further, when the curing reaction is completed, the first member can be firmly fixed. In addition, the worker can perform other constructions during curing. Above all, this step can be performed within 0.5 hours after the first adhesive composition and the first adhesive layer come into contact with each other. This is because there is a concern that the adhesive strength to the first member will decrease as the curing progresses. Further, after the first member is attached to the coated surface of the first adhesive composition, it may be heated to accelerate the curing reaction. The curing time, curing temperature, and heating temperature are the same as those described in the above-mentioned section "A. First embodiment of the method for producing an article".

The separator 23 may be arranged on the other surface (the surface opposite to the surface on which the first adhesive composition 22 is applied). Next, the first member 1 is bonded to the coated surface of the first adhesive composition 22 of the multilayer adhesive sheet 40 (FIG. 11 (b), first bonding step). Further, the second member 2 is bonded to the other surface of the first adhesive layer 24 of the multilayer adhesive sheet 40 (FIG. 11 (c), second bonding step). When the separator 23 is arranged on the other surface of the first adhesive layer 24 of the multilayer adhesive sheet 40, the second bonding step is performed by peeling the separator 23.

The preparatory step of applying the first adhesive composition to one surface of the first adhesive layer of the first adhesive sheet to prepare the multilayer adhesive sheet, and the first adhesive layer of the multilayer adhesive sheet. The other surface has a bonding step of bonding the first member, the first adhesive composition contains a first adhesive component, and the first adhesive layer contains a second adhesive component. The first adhesive composition and the first adhesive sheet are configured so that the first adhesive component and the second adhesive component are cured and adhered by contacting each other.

FIG. 19 is a process diagram showing an example of an eighth embodiment of a method for manufacturing an article. The eighth embodiment of the method for manufacturing an article has a preparation step (FIG. 19 (a)) and a bonding step (FIG. 19 (b)). FIG. 19 (a) is the same as FIG. 11 (a) described above. FIG. 19B is the same as FIG. 11B described above, except that the first member is bonded to the other surface of the first adhesive layer of the multilayer adhesive sheet instead of the second member. The first adhesive composition 22 and the first adhesive layer 24 become the cured adhesive layer 3 when the curing reaction is completed (FIG. 19 (c)). As a result, the article 10 having at least the first member 1 and the cured adhesive layer 3 can be obtained. Note that P in FIG. 19B indicates a region (cured region) cured by contact between the first adhesive composition 22 and the first adhesive layer 24.

According to the eighth embodiment of the method for manufacturing an article, a first adhesive composition is applied in advance on the first adhesive layer of the first adhesive sheet to prepare a multilayer adhesive sheet, and a member is prepared for the multilayer adhesive sheet. The bonding time can be shortened, and the first member, the first adhesive composition, and the first adhesive layer can be integrated with each other with a strong adhesive force developed by curing. can. Further, since the above-mentioned multilayer adhesive sheet is used, it is not necessary to mix two liquids such as a two-component adhesive, and it is possible to easily manufacture an article. In addition, the thickness of the first adhesive layer can be controlled, and problems such as uneven application of the adhesive, forgetting to apply the adhesive, and protrusion from the adherend surface can be suppressed. Further, by impregnating the first adhesive layer with another member, or by arranging the other member at the contact interface between the first adhesive composition and the first adhesive layer, the other member is provided by the cured adhesive layer. It can be held and fixed, and the first member can be repaired or reinforced by the other members. In this way, by forming one of the two types of liquid materials of the two-component separate coating type adhesive into a sheet, it is possible to simplify the production of the article as compared with the coating bonding method.

Further, since the first adhesive composition and the first adhesive sheet have different forms, the first adhesive composition and the first adhesive sheet can be appropriately selected according to the type of the member in consideration of suitability. Therefore, for example, it is useful when the first member has an uneven surface or a porous surface.

Further, since the first adhesive composition is liquid, the first adhesive component contained in the first adhesive composition when the first adhesive composition and the first adhesive layer of the first adhesive sheet come into contact with each other. And the second adhesive component contained in the first adhesive layer can be easily diffused, and the reactivity can be enhanced.

In the method for manufacturing an article of the present embodiment, except that the second member bonding step is not performed and the first member is bonded to the other surface of the first adhesive layer of the multilayer adhesive sheet instead of the second member. It can be the same as the content described in the above-mentioned section "B. Fourth embodiment of the method for manufacturing an article". Hereinafter, each step of the method for manufacturing the article of the present embodiment will be described.

1. 1. Preparation step The preparation step in the eighth embodiment of the method for manufacturing an article is a step of applying the first adhesive composition to one surface of the first adhesive layer of the first adhesive sheet to prepare a multilayer adhesive sheet. be. The preparatory step can be the same as the preparatory step of the seventh embodiment.

Further, in the preparatory step, after the application of the first adhesive composition, one surface of the second adhesive layer of the second adhesive sheet is bonded to the application surface of the first adhesive composition of the first adhesive sheet. It may be a multi-layer adhesive sheet.

In this case, a liquid first adhesive composition, a first adhesive sheet having a first adhesive layer, and a second adhesive sheet having a second adhesive layer are used, and the first adhesive composition is the first. The first adhesive layer contains a second adhesive component, the second adhesive layer contains a fourth adhesive component, and the first adhesive composition and the first adhesive sheet contain an adhesive component. And the second adhesive sheet are configured so that the first adhesive component and the second adhesive component are cured and adhered by contacting each other, and the first adhesive component and the fourth adhesive are bonded. The components are configured to cure and adhere when they come into contact with each other.

FIG. 20 is a process diagram showing another example of the eighth embodiment of the method for manufacturing an article. First, the first adhesive composition 22 is applied to one surface of the first adhesive layer 24 of the first adhesive sheet 12, and then the first adhesive composition 22 is applied to the coated surface of the first adhesive sheet 12. 2 One surface of the second adhesive layer 26 of the adhesive sheet 13 is bonded to prepare a multilayer adhesive sheet 50 (FIGS. 20 (a) to 20 (b), preparation step). The second adhesive sheet 13 may have a separator 27 on at least one surface side of the second adhesive layer 26, and in this case, even if the separator 27 is arranged on the other surface of the second adhesive layer 26. good. Next, the first member 1 is bonded to the other surface of the first adhesive layer 24 of the multilayer adhesive sheet 50 (FIG. 20 (c), bonding step). When the separator 27 is arranged on the other surface of the second adhesive layer of the multilayer adhesive sheet 50, the bonding step is performed by peeling off the separator 27. The first adhesive composition 22, the first adhesive layer 24, and the second adhesive layer 26 become a cured adhesive layer 3 when the curing reaction is completed (FIG. 20 (d)). As shown in FIG. 20D, when the separator 27 of the second adhesive sheet 13 is arranged on the surface of the cured adhesive layer 3 opposite to the first member 1 after the bonding step, the separator 27 is used. It may be peeled off. As a result, the article 10 having at least the first member 1 and the cured adhesive layer 3 can be obtained. In FIG. 20C, P indicates a region (cured region) cured by contact between the first adhesive layer 24 and the first adhesive composition 22, and Q indicates the first adhesive composition 22 and the first adhesive composition 22. 2 The region (cured region) cured by the contact of the adhesive layer 26 is shown.

The method of bonding the second adhesive sheet can be the same as the method of bonding the first adhesive sheet according to the fifth embodiment of the above-mentioned method for manufacturing an article.

In the second adhesive sheet, another member may be arranged in advance on one surface (the surface on the first member side) of the second adhesive layer, and the second adhesive layer is impregnated with the other member. May be good. This is because the first adhesive layer, the first adhesive composition, and the second adhesive layer are contact-cured, so that other members can be included in the cured adhesive layer. For example, as shown in FIG. 20 (a), when the second adhesive sheet 13 in which the other member 5 is impregnated in the second adhesive layer 26 is used, it is hard-bonded as shown in FIG. 20 (c). An article 10 in which the other member 5 is included in the layer 3 can be obtained. Further, since the curing reaction of the second adhesive layer does not proceed until it comes into contact with the first adhesive composition, for example, a second adhesive sheet in which another member is impregnated in the second adhesive layer or a second adhesive layer The second adhesive sheet in which the other member is arranged on one surface can be stored for a long period of time until before the preparation process, and the second adhesive sheet can be used depending on the timing of bonding to the first member. can.

In the example shown in FIG. 20, the first adhesive layer 24 is impregnated with the other member 4, and the second adhesive layer 26 is impregnated with the other member 5, but the first adhesive layer and the second adhesive layer are impregnated. One adhesive layer may be impregnated with another member, or both adhesive layers may be impregnated with another member.

2. Laminating Step The laminating step in the eighth embodiment of the method for manufacturing an article is a step of laminating a first member to the other surface of the first adhesive layer of the multilayer adhesive sheet. In the bonding step, in the first member bonding step of the fourth embodiment of the above-mentioned manufacturing method of the article, the first member is bonded to the other surface of the first adhesive layer of the multilayer adhesive sheet instead of the second member. The same can be done except for matching.
