Description

  The present invention relates to a storage and mixing container for a plurality of liquids and a method for preparing a mixture. More specifically, the present invention relates to a storage and mixing container for a plurality of liquids and a method for preparing a mixture, which can be mixed while visually grasping a mixed state by a color tone difference in a sealed space.

  Conventionally, as an application material such as waterproofing materials, flooring materials, wall materials, concrete protective materials, and anti-corrosion / rust-proof lining agents for steel products used in the construction field, elastic coatings have been used for the purpose of protecting the substrate. The material to be formed is used, and this material is required to have a followability to expansion and contraction due to a base crack or a temperature change, waterproofness, and corrosion / rust prevention. However, even when a material satisfying such required physical properties is used, mechanical damage may occur during construction and use, or cracks may occur due to swelling during aging.

  For such mechanical damage and cracks, it is usually preferable that repair is performed using the same material. However, generally, since such a repair location has a small area, the amount of material used as a repair material is small. For this reason, many problems such as preparation of tools and material loss have occurred in order to stir and mix materials contained in oil cans. In particular, in the case of an ultra-fast curing type urethane material using a high-pressure spray machine, it is necessary to use a large dedicated machine, which has been an economic problem.

  By the way, the two-component curable urethane material is a material that can satisfy the above-mentioned physical properties for a low price, and it is used for various waterproofing materials, flooring materials, wall materials, concrete protective materials, and steel products. It is used as a coating material for rust lining agents. However, at present, as a urethane material for forming an elastic coating film such as a waterproof material, a floor material, and a protective lining material, there are few commercially available repair materials in small cans. For this reason, in actual repairs, a resin different from the urethane material used in the damaged or cracked part, such as urethane sealant (soft) or epoxy resin (hard) contained in the cartridge, is used. It was.

  In addition, when repairing with the same urethane material, it is necessary to measure two liquids from a large can such as an oil can. However, in accurately measuring the weight in a complicated site, it was extremely difficult due to the lack of appropriate equipment. As a result, even if repair was performed, the physical properties of the repair material were reduced due to the inaccuracy of the blending ratio of the two liquids used as the repair material.

  A small amount of resin in a film pack is also commercially available as a urethane-based repair material. However, commercially available urethane-based repair materials are so-called “easy to dismantle” materials and are used for special applications such as electrical contacts and substrate sealing materials, so they are soft and have very little elongation. It is designed to have physical properties. Therefore, the urethane-based repair material currently on the market is not suitable as an elastic coating material for construction or as an anticorrosion / rust prevention lining material for steel products.

  Under such circumstances, the market has strongly desired the development of easy-to-handle urethane materials that can be used as simple repair materials for building-use elastic coating materials and anti-corrosion and rust prevention materials for steel products. .

  By the way, conventionally, in medical and food applications, a system in which a partition is provided in the middle of a film pack to fill the two liquids, and the two liquids are mixed by removing the partition at the time of use. In addition to medical and food application fields, for example, as in Patent Documents 1 to 3, film packs that mix a base material and a curing agent are known. Incidentally, in the film packs of Patent Documents 1 and 2, a mechanical partitioning method is disclosed, and in the film pack of Patent Document 3, a partitioning method by a thermal fusion method is disclosed.

In addition, a technique for generating a color tone difference before and after the reaction for the purpose of grasping the completion point of the reaction when the two liquids are mixed and reacted is also known. Patent Document 4 discloses a technique for fading and making colorless by mixing a methylene-based basic dye with a main component in a two-component epoxy resin adhesive and reacting with an amino group when mixed with a curing agent. Has been. Further, in Patent Document 5, when the reducing agent and the peroxide are blended in the main agent and the curing agent as the adhesive, and the main agent and the curing agent are mixed and reacted, the reaction is completed due to discoloration. A technique for facilitating determination of a time point is disclosed.

  However, the film pack disclosed in Patent Documents 1 to 3 provided with a partition and filled with two liquids could not confirm the mixed state as to whether or not the two liquids were uniformly mixed.

  In addition, since the discoloration techniques disclosed in Patent Documents 4 and 5 are both techniques in which discoloration proceeds due to the progress of the reaction, discoloration proceeds with time even when the blending ratio is slightly shifted. Resulting in. Therefore, the discoloration by the techniques disclosed in Patent Documents 4 and 5 merely means that the two liquids are mixed, and it is not possible to confirm whether or not the mixing state at the time of mixing is uniform. could not. For this reason, when the mixture in which the mixed state is not uniform was applied, the physical properties of the mixture after application could not be expressed.

  By the way, the two-component curable urethane material has drawbacks that, when the mixing state of the two components of the main agent and the curing agent is poor, the physical properties of the corners are not exhibited, and partial uncuring occurs. However, it is difficult to confirm the mixing status of the main agent and curing agent, and even in full-scale construction using a propeller and a turbine type agitator, the agitation time is determined based on the intuition of technicians. In order to mix the whole uniformly, skill of skilled technicians is required. For this reason, a means for confirming the mixed state by a simple operation has been demanded in the market.

  As described above, at present, as a urethane material for forming an elastic coating film such as a waterproof material, a floor material, and a protective lining material, there are few commercially available repair materials in a small can. For this reason, there has been a strong demand in the market for the development of easy-to-handle urethane materials that can be used as various repair materials.

  The present invention has been made in view of the problems as described above, and can visually confirm the mixed state when a plurality of liquids are mixed, and a small amount of material sufficient for the required amount during repair is sealed. Another object of the present invention is to provide an easy-to-handle storage and mixing container for multiple liquids and a method for preparing a mixture.

  In order to solve the above problems, the present inventors are a sealed container that can contain only a small amount of material, and can mix a plurality of liquids in the sealed space of the sealed container. We focused on the point that it can be visually recognized from the outside. As a result, the inside of the sealed container is divided by a partition to form a plurality of independent spaces, each of which contains a plurality of types of liquids having different color tones, and when mixing, the partition is removed to create a merged space. As a result of the formation, the present inventors have found that the color tone of the mixture may be different from the color tone of a plurality of types of liquids before mixing, and the present invention has been completed. More specifically, the present invention provides the following.

  (1) A plurality of types of liquids to be mixed are stored and stored in each of a plurality of independent spaces formed by partitioning the inside of the sealed container with a partition. Removing and forming a merged space, mixing the plural types of liquids in the merged space, and storing and mixing multiple liquids for obtaining a mixture, each of the multiple types of liquids, A color difference generating agent that generates a color difference before and after the mixing is blended so that the mixing state can be visually grasped at the time of mixing, and each of the plurality of types of liquids is adjusted by the color difference generating agent. Storage and mixing container for multiple liquids that are colored.

  According to the multiple liquid storage and mixing container of (1), only a small amount of material can be accommodated. For this reason, problems such as preparation of tools and material loss in the case of using a large canned material for a small area range, which has been a conventional problem, can be solved.

  In addition, according to the multiple liquid storage and mixing container of (1), multiple liquids can be mixed in a sealed space. For this reason, at the time of mixing, it can avoid that a bubble mixes in a material and is excellent in the smoothness of the surface at the time of apply | coating a mixture. Furthermore, since all of the liquid contained in the independent space in the container is mixed, it is not necessary to weigh the mixed material in a complicated site, and a mixture with an accurate blending ratio can always be obtained.

  Furthermore, according to the storage and mixing container for plural liquids of (1), since a color difference occurs before and after mixing, the mixing state at the time of mixing can be visually grasped from the outside. For this reason, it can be easily confirmed whether or not the mixing state at the time of mixing has become uniform, and since mixing failure can be avoided, the physical properties of the coating film obtained when the mixture is applied can be reliably expressed. it can.

  In addition, in the storage and mixing container for multiple liquids of (1), the method for generating a color difference that occurs before and after mixing is not particularly limited. It may be due to color mixing or may be discoloration due to reaction. Moreover, as long as mixing can be visually recognized by a color tone difference, it may be colored or colorless. For example, a mixture that becomes colorless after mixing a plurality of colored liquids may be obtained, or a mixture that becomes colored after mixing a plurality of colorless liquids may be obtained.

  (2) The storage / mixing container for a plurality of liquids according to (1), wherein the color difference is caused by additive color mixing or subtractive color mixing of the color tones of the plurality of types of liquids.

  The color difference in the storage / mixing container of the plural liquids of (2) may be an additive color mixture in which the lightness is added each time the colors are mixed, or a subtractive color mixture in which the lightness decreases each time the colors are mixed. . The additive color mixture and the subtractive color mixture are changes in color tone caused by simply mixing colors, so that the mixed state can be immediately recognized. For this reason, it is possible to immediately grasp the mixed state without waiting for the passage of time due to the reaction.

  (3) The multiple liquid storage and mixing container according to (1) or (2), wherein each of the plurality of types of liquids has a total light transmittance of 20% or more.

  In the storage / mixing container for a plurality of liquids (3), since the total light transmittance of each of the plurality of types of liquids contained is 20% or more, the plurality of types of liquids are transparent. Here, the total light transmittance is measured by JIS K7105-1981 (plastic engineering property test method). If the plurality of types of liquids to be mixed have transparency with a total light transmittance of 20% or more, the degree of mixing can be easily grasped when the liquids are mixed.

  (4) The color difference generating agent is a pigment and / or dye having an average particle size of 0.2 μm or less, and the content thereof is 20 ppm or more and 5000 ppm or less with respect to 100 parts by mass of the plurality of types of liquids. A storage and mixing container for plural liquids according to any one of (1) to (3).

  In the multiple liquid storage / mixing container of (4), a plurality of types of liquids containing a specific amount of pigment and / or dye having a specific particle diameter are used as the color difference generating agent. When a dye is used, it may be dissolved or dispersed in each of the plural liquids used. If the particle size and content of the pigment and / or dye are within the above ranges, the plurality of types of liquids after blending have transparency. If multiple types of liquids to be mixed have transparency, the liquid can transmit light, so even if there is a liquid depth, the degree of mixing can be easily grasped. it can.

  (5) The plurality of types of liquids are respectively a main component and a curing agent of a two-component curable urethane material, and the main component is an isocyanate and / or urethane prepolymer having xylylene diisocyanate and / or diphenylmethane diisocyanate as a structural unit. (1) to (3) is a multi-liquid storage and mixing container according to any one of (1) to (3).

  (5) The storage and mixing container for multiple liquids is an isocyanate having a plurality of types of liquids as a main component and a curing agent of a two-component curable urethane material, respectively, and the main component as a constituent unit of xylylene diisocyanate and / or diphenylmethane diisocyanate. And by setting it as a urethane prepolymer, it is excellent in the balance of both the reactivity with a hardening | curing agent, and the physical property of the coating film obtained from a mixture.

  If the main agent is an isocyanate and / or urethane prepolymer having xylylene diisocyanate and / or diphenylmethane diisocyanate as a structural unit, the time until the viscosity increases due to gelation after making the mixture (pot life) is about 5 to 10 minutes. Become. The time of about 5 to 10 minutes is just enough to perform repair work using the mixture. In addition, it is possible to realize a wide range of hardness of the coating film obtained from the mixture. For this reason, when using the obtained mixture as a repair material, it can be applied to a wide range of applications from a relatively soft coating used for waterproofing to a relatively hard coating used for flooring.

  (6) The multi-liquid storage and mixing container according to any one of (1) to (5), wherein the sealed container is made of a transparent film having flexibility, and the mixing is performed by hand.

  In the storage and mixing container for multiple liquids of (6), mixing can be carried out by human hands by using a flexible film as a transparent film. Thereby, it is not necessary to use equipment for stirring and the like, and mixing can be easily performed on site.

  (7) A mixture preparation method for mixing a plurality of types of liquids in a sealed container to obtain a mixture, wherein each of the plurality of types of liquids is toned to generate a color difference before and after the mixing. The sealed container has a plurality of independent spaces divided by partitions, and each of the independent spaces contains and stores a plurality of types of liquids to be mixed in a state that is visible from the outside. A partition removal step of removing the partition to form a merged space, and a manual gripping step of mixing the plurality of types of liquids while visually grasping the mixed state by grasping the merged space by hand. And a method for preparing a mixture.

  The mixture preparation method of (7) can adjust a mixture only by implementing a partition removal process and a hand kneading process. Moreover, according to the mixture preparation method of (7), only a small amount of materials can be mixed in the sealed space while confirming the mixed state. Therefore, it is possible to prepare a mixture very easily even in complicated sites, without causing problems such as preparation of tools and material loss, and without mixing bubbles at the time of mixing. This mixture can be obtained without causing poor mixing.

  (8) The method for adjusting a mixture of a plurality of liquids according to (7), wherein the color tone difference is caused by additive color mixing or subtractive color mixing of each color tone of the plurality of types of liquids.

  The difference in color tone in the method for adjusting a mixture of plural liquids in (8) may be additive color mixing in which the lightness is added each time the colors are mixed, or subtractive color mixing in which the lightness decreases each time the colors are mixed. This has the same effect as (2) described above.

  (9) Consists of a heat-sealable transparent film, has a flat bag shape as a whole, and heat-seals opposite side parts, and between the both side parts, A partition that divides the space into two and forms two independent spaces, and the main component and the curing agent of the two-component curable urethane material are separately stored and stored in each of the independent spaces. In the mixing, the partition is removed to form a merged space, and the main component and the curing agent are mixed in this merged space. A cylindrical body forming step of forming a cylindrical body having openings on both side sides, and a periphery of the independent space formed in the future gradually narrows toward the both side sides in each of the openings. And the opening A filling port forming step of providing a heat seal portion so as to leave at least a part as a filling port of the main agent or the curing agent, and a partitioning step of providing the partition between the both side portions of the cylindrical body, A first filling step of inserting a nozzle from one of the filling ports to fill one of the main agent or the curing agent, and sealing the filling port while removing the nozzle from one of the filling ports.

A second sealing step of forming a second independent space by sealing the mouth, and a method for producing a two-component storage and mixing container.

  In the method for producing a two-component storage and mixing container of (9), in the filling port forming step, the heat seal portion is provided so as to gradually narrow toward the side portions on both sides while leaving the filling port of the main agent or the curing agent. It is a feature. According to this, mixing of bubbles can be reduced during filling and sealing of the main agent or curing agent. In addition, it is possible to prevent the main agent or the curing agent from remaining in the corner portions in the sealed package during mixing, resulting in poor mixing.

  Note that “so as to gradually narrow toward the side portions on both sides” is, for example, a seal shape in which the four corners of a sealing bag body having a rectangular outer shape as a whole are dropped. The shape that gradually narrows is not particularly limited, and may be linear, curved, or stepped. Moreover, the heat seal part may be performed by surface sealing at all corners, and line sealing may be performed only at the periphery of the independent space.

It is. Thus, when the nozzles in the first sealing step and the second sealing step that are subsequently performed are pulled out, the respective filling ports that are subsequently sealed and sealed are not soiled with the liquid of the main agent or the curing agent. Therefore, product loss due to a seal failure can be reduced.

  (11) The method for producing a two-component storage / mixing container according to (9) or (10), wherein the transparent film is an easy-sealable film having a contamination sealability.

  In the method for producing a two-component storage / mixing container of (11), a transparent film formed of a resin having at least an inner surface made of a resin excellent in dust sealing property capable of being dust sealed is used as the transparent film. If the inner surface has a contamination sealing property, the sealing can be reliably performed even when the contents adhere when heat sealing. Furthermore, if sealing is performed in a state where the contents slightly overflow during heat sealing, the internal bubbles can be reliably removed.

  According to the multi-liquid storage and mixing container of the present invention, since only a small amount of material can be accommodated, when a large canned material is used for a small area range, which has been a problem in the past. It is possible to eliminate problems such as tool preparation and material loss.

  In addition, since a plurality of liquids can be mixed in the sealed space, it is possible to avoid bubbles from being mixed into the material during mixing, and the surface smoothness when the mixture is applied is excellent. Furthermore, since all the liquids contained in the independent space in the container are mixed, it is not necessary to weigh the mixed material in a complicated place, and a mixture with an accurate blending ratio can always be obtained.

  In addition, since a color difference occurs before and after mixing, the mixing state at the time of mixing can be visually recognized from the outside, and it can be easily confirmed whether or not the mixing state at the time of mixing is uniform. it can. For this reason, poor mixing can be avoided, and the physical properties of the coating film obtained when the mixture is applied can be reliably expressed.

  Moreover, according to the mixture preparation method which is another invention, a mixture can be adjusted only by implementing a partition removal process and a hand kneading process. For this reason, it is possible to easily mix only a small amount of material in a sealed space while checking the mixing state. Therefore, it is possible to prepare a mixture very easily even in a complicated place, and to prepare tools and Without causing problems such as material loss, and without mixing bubbles during mixing, it is possible to always obtain a mixture having an accurate blending ratio without causing poor mixing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The first independent space 20 contains a main component 56 of a two-component curable urethane material toned in blue, and the second independent space 30 contains a curing agent 57 toned in yellow. Yes.

  FIG. 2 is a front view of the multiple liquid storage and mixing container 10 of the present embodiment. In this embodiment, the partition 53 is provided in the substantially center position of the both sides of the sealed container 40, and the formed first independent space 20 and second independent space 30 have substantially the same volume. As a result, the contained main agent 56 toned in blue and the curing agent 57 toned in yellow are accommodated in substantially the same volume.

  In the present invention, the installation position of the partition in the sealed container is not particularly limited. The position of the partition can be appropriately selected according to the mixing ratio of the plurality of liquids to be stored. Since the partition position according to the mixing ratio is determined, the filling amount in the subsequent filling operation can always be a constant amount.

  In addition, the multiple liquid storage and mixing container 10 according to the present embodiment includes the peripheral edge of the first independent space 20 and the second independent space 30 formed by the heat seal portions 22 and 23 provided on both sides of the sealed container 40. Each of the peripheral edges is gradually narrowed from the partition 53 side toward both side portions. As in the present embodiment, if it gradually narrows toward the first independent both sides, the first independent space is created by filling the main agent 56 and the curing agent 57 or by creating the lateral seal portions 23 and 33. When the sealing operation of the 20 and the second independent space 30 is performed, the amount of bubbles such as air can be reduced. Moreover, the mixing property at the time of obtaining the mixture 59 (refer FIG. 9) by mixing the main ingredient 56 and the hardening | curing agent 57 can be improved, and while shortening mixing time, a uniform mixture can be obtained.

[partition]
FIG. 3 is a view showing a partition 53 used in the multiple liquid storage and mixing container 10 according to the present embodiment. The partition 53 used in this embodiment includes a fitting member A51 and a fitting member B52. FIG. 3A is a cross-sectional view of the fitting member A51. The fitting member A51 includes a substantially cylindrical shape portion 51a that is a fitting portion with the fitting member B52, and has a flat portion 51b that serves as a stopper when fitted to the fitting member B52.

  FIG. 3B is a cross-sectional view of the fitting member B52. The fitting member B52 includes an open substantially cylindrical shape portion 52a for fitting the fitting member A51 therein, and the fitting member A51 is disposed on the inner side near the open position of the substantially cylindrical shape portion.

When the subsequent mixing is carried out manually, it is preferable to use a partition type partition from the viewpoint of workability during manual handling. If it is a partition plate type partition, there is no need to bond the sealed container, so that no adhesion marks remain on the container when the partition is removed. Since the adhesion mark becomes a non-uniform portion of the thickness of the container, there is a case where workability is lowered until a uniform mixed state is obtained when carrying out the hand kneading. Specific examples of the partition plate system preferably used in the present invention include the system described in Japanese Utility Model Publication No. 59-136466.

[Multiple liquid storage and mixing container manufacturing method]

Each step will be described below with reference to the drawings.

[Tubular body forming step]
A cylindrical body formation process is a process which uses a transparent film, has an opening part in the both-sides side part 40b, and forms the cylindrical body 40a used as the future sealed container 40 (FIG. 4 (a)).

  If the material of the transparent film used in the present invention can withstand use when forming a container, such as heat-sealability when sealing, storage stability of the resulting container, strength to withstand itching, Although it is not particularly limited, it is preferable to use a transparent film formed of a resin having at least an inner surface that is capable of being sealed in a dusty manner and having a good sealing property. If the inner surface has a contamination sealing property, the sealing can be reliably performed even when the contents adhere when heat sealing. Furthermore, if sealing is performed in a state where the contents slightly overflow during heat sealing, the internal bubbles can be reliably removed.

  Examples of the resin having excellent sealing properties include EVA (ethylene-vinyl acetate copolymer), EAA (ethylene-acrylic acid copolymer), EEA (ethylene-ethyl acrylate copolymer), and EMAA (ethylene-methacrylic acid). (Copolymer polyolefin resin such as acid methyl copolymer), LLDPE (linear low density polyethylene) by metallocene catalyst, ionomer, or a mixture of PE (polyethylene) and EVA.

It is also possible to use it. The lamination method is not particularly limited, and a known method such as dry lamination or coextrusion lamination can be employed. Examples of the film used for the purpose of improving the strength include oriented nylon and PET (polyethylene terephthalate).

  In addition, the thickness of the transparent film used in the present invention is not particularly limited, but it is necessary to make the thickness satisfying the balance between thinness and strength from the viewpoint of carrying out mixing by hand.

  Specific examples of the transparent film used in the present invention include, for example, an ionomer inflation film (trade name: HM-07) manufactured by Tamapoli Co., Ltd. and an LLDPE inflation film (trade name: UB-3) manufactured by the same company. By laminating by dry lamination or the like and setting the thickness to about 80 μm, it is possible to obtain a good film in both heat sealability and flexibility during handling. Furthermore, when nylon or PET is laminated on the outside, a thickness of about 15 μm is sufficient in strength.

[Filling port formation process]
FIG. 4 is a diagram showing a filling port forming step in the method for producing a multi-liquid storage and mixing container according to this embodiment. In the filling port forming step, the peripheral edges of the first independent space 20 and the second independent space 30 (see FIG. 2) to be formed in the future are respectively formed on both sides of the openings of the cylindrical body 40a to be the sealed container 40 in the future. In this step, the heat seal portions 22 and 32 are provided so as to gradually narrow toward the bottom and to leave at least a part of the opening as a filling port for the main agent 56 or the curing agent 57 (see FIG. 2).

  In the present embodiment, as shown in FIG. 4B, the inner peripheral edges of the heat seal portions 22 and 32 have no corners and are formed in a shape that draws a round arc. That is, each of the four heat seal portions has an R-shaped curved portion 32a that gradually narrows toward the side portions 40a and 40b, and both sides so that the filling port formed by the seal gradually narrows starting from the end point. It has a shape including a straight line portion 32b extending toward the side portions 40a and 40b. Moreover, after the heat seal part 22 is formed, when the mixture is taken out, a notch 21 is provided as an opportunity to open the container.

  The “heat seal part” in the present invention only needs to be provided so that the peripheral edge of each independent space gradually narrows toward both side parts, particularly when a filling port is formed by linear heat seal. The angle between the filling port and the side is preferably 90 degrees or more, and more preferably 120 degrees or more so that the filling port gradually narrows toward the side.

  FIG. 5 is a modification of the shape of the heat seal part in the present invention. Since the configuration other than the heat seal portion is the same as that in FIG. 4B, the description thereof is omitted. Fig.5 (a) is an example which shows the shape of the heat seal part in which a periphery is formed in a straight line. As shown in FIG. 5 (a), the heat seal portion of the present invention has a straight line gradually narrowing toward both side portions and a side edge so that the filling port formed by the seal gradually narrows starting from the end point. It may be a shape like the heat seal portion 61 formed by a straight line extending toward the surface. Moreover, FIG.5 (b) and (c) are examples which show the shape of the heat seal part in which a periphery is formed with a curve. In the present invention, as shown in FIG. 5 (b), it may have a shape like an R-shaped heat seal portion 62 that gradually narrows toward both sides, as shown in FIG. 5 (c). In addition, the heat seal portion 63 may have a shape like the heat seal portion 63 in which the inner peripheral edge of the heat seal portion has an elliptical shape as a whole.

[Partition process]
FIG. 6 is a diagram showing a partitioning step in the method for producing a multi-liquid storage and mixing container according to this embodiment. A partition process is a process of providing the partition 53 between the said both sides of the cylindrical body used as the future sealed container 40 in which the heat seal parts 22 and 32 and the cut | notch 21 were formed.

  In this embodiment, as shown in FIG. 6 (a), a fitting member A51 and a fitting member B52 are provided at substantially the center between both side portions of the cylindrical body that will become the sealed container 40 in the future. Between these, it prepares so that it may become the positional relationship which pinches | interposes the cylindrical body used as the sealed container 40 in the future. Subsequently, as shown in FIG. 6 (b), the fitting member A51 and the fitting member B52 sandwich the cylindrical body that will become the sealed container 40 in the future from above and below, and the fitting member A51 and the fitting member B52 are connected. The partition 53 is installed by fitting. By installing the partition 53, the cylindrical body that will be the future sealed container 40 is divided into a space that will be the future first independent space 20 and a future second independent space 30.

  In the present invention, the installation position of the partition in the sealed container is not particularly limited. The position of the partition can be appropriately selected according to the mixing ratio of the plurality of liquids to be stored.

[First filling step]
FIG. 7 is a diagram showing a series of steps from the first filling step to the second sealing step. Fig.7 (a) is a figure which shows a 1st filling process. In the first filling step in the present embodiment, the nozzle 55 is inserted from the filling port formed in the heat seal portion 22 on the side of the future sealed container 40 on the side having the space that will become the first independent space 20 in the future. Inserted and filled with the main agent 56 toned in blue.

  The first filling step in the present invention may be a step of filling any of a plurality of liquids to be accommodated. When the position of the partition is set in accordance with the mixing ratio of the plurality of liquids to be stored, the order of filling is not particularly limited as long as the liquid is filled in accordance with the ratio of the independent space.

  Moreover, in this invention, it is preferable that the nozzle used for each filling process is a double tube which consists of an inner tube and an outer tube. By using a double tube nozzle and filling the liquid only from the inner tube of the double tube in each filling step, each filling port to be sealed after the nozzle is pulled out in each sealing step described below Is not soiled with the liquid that has been filled. Therefore, product loss due to a seal failure can be reduced.

  Furthermore, by introducing a gas that can be dissolved in the liquid to be accommodated from the outer pipe by using a nozzle that has become a double pipe, the liquid to be contained in the sealing in each subsequent sealing process is introduced. The content rate of mixed air can be reduced. If filling is performed while introducing a gas that can be dissolved, after the filling port is sealed, the gas remaining inside dissolves in the liquid, so the bubbles contained in the liquid are small, and the amount left as gas Will be less. According to the mixture in which the bubble content is reduced, the surface smoothness of the coating film obtained by coating the mixture is excellent.

  In the present invention, when gas is introduced from the outer tube, it is not particularly limited as long as it is a gas that can be dissolved in a liquid. In the present invention, it is preferable to use carbon dioxide gas because it is easily available and easy to handle.

[First sealing process]
FIG.7 (b) is a figure which shows a 1st sealing process. In the first sealing step in the present embodiment, the nozzle 55 is inserted from the filling port formed in the heat seal portion 22 on the side portion of the future sealed container 40 on the side having the space to be the first independent space 20 in the future. While pulling, the filling port is heat-sealed to form the horizontal seal portion 23 to form the first independent section. Thereby, the main agent 56 toned in blue is sealed in the first independent space 20.

[Second filling step]
FIG.7 (c) is a figure which shows a 2nd filling process. In the second filling step in the present embodiment, the nozzle 55 is inserted from the filling port formed in the heat seal portion 32 on the side of the future sealed container 40 on the side having the space that will become the future second independent space 30. Inserted and filled with a curing agent 57 toned yellow.

[Second sealing process]
FIG.7 (d) is a figure which shows a 2nd sealing process. In the second sealing step in the present embodiment, the nozzle 55 is inserted from the filling port formed in the heat seal portion 32 on the side of the future sealed container 40 on the side having the space that will become the future second independent space 30. While pulling, the filling port is heat-sealed to form the horizontal seal portion 33 and the second independent section is formed. Thereby, the curing agent 57 toned in yellow is sealed in the second independent space 30.

[Bubble contained in a container for storing and mixing multiple liquids]
As shown in FIG. 8A, the multi-liquid storage and mixing container 10 obtained by the above manufacturing method has a feature that the content of the bubbles 70 is very small. Here, FIG. 8B shows a conventional storage and mixing container 10 ′, which contains more bubbles 71 than in FIG. 8A.

  In the present invention, if the content rate of bubbles due to air or the like in the liquid to be contained is reduced, the subsequent mixing is performed in a closed system, resulting in a reduction in the content rate of bubbles in the mixture. If the bubble content can be reduced, the surface of the coating film obtained by coating the mixture can be excellent in smoothness.

[Packaging]
As shown in FIG. 10, the multi-liquid storage and mixing container 10 of the present invention is preferably sealed and housed together with a desiccant 80 in an outer container 90 having a water vapor barrier property. According to this, since the storage / mixing container 10 for plural liquids can be shielded from water vapor in the air, even if the film constituting the sealed container 40 is a film having a low water vapor barrier property such as polyamide / polyethylene. , Water vapor can be prevented from entering the sealed container 40. For this reason, the swelling of the sealed container 40 can be avoided, and the storage time before use can be prolonged.

  The outer container 90 is not particularly limited, and may be a flexible packaging bag or a molded product having hardness as long as it has water vapor barrier properties. As an example of the preferable exterior container 90, the laminated | multilayer film which contains an aluminum foil or an aluminum vapor deposition film, and can be heat sealed can be mentioned, for example. Also, the desiccant 80 is not particularly limited, and a known desiccant such as silica gel can be used. A plurality of storage and mixing containers 10 may be accommodated in the outer container 90.

[Method of preparing mixture]
A mixture preparation method using the multiple liquid storage and mixing container 10 according to this embodiment will be described. FIG. 9 is a diagram showing the steps of a mixture preparation method using the multiple liquid storage and mixing container 10 according to the present embodiment. The mixture preparation method includes a partition removing step and a manual kneading step.

[Partition removal process]
Fig.9 (a) is a figure which shows a partition removal process. In the partition removal step, the fitting between the fitting member A51 and the fitting member B52 forming the partition 53 is released, and the fitting member A51 and the fitting member B52 are separated. As a result, the first independent space 20 and the second independent space 30 are merged to form one merged space, and the main agent 56 toned in a blue system and contained in the first independent space 20, and the second independent space. The hardener 57 toned in yellow color that is accommodated in the space 30 is mixed in one merged space.

[Hand massage process]
FIG. 9B is a diagram illustrating a manual kneading process. The manual kneading step is a step of mixing the main agent 56 and the curing agent 57 while visually grasping the mixed state by manually pinching the merged space formed by removing the partition 53. In FIG. 9B, since the semi-mixing part 58 near the center, the main agent 56, and the curing agent 57 are mixed, it is obvious at a glance that the mixing is still insufficient.

  In this embodiment, the main agent 56 toned in a blue system and the curing agent 57 toned in a yellow system are mixed in a combined sealed space by hand-rubbing, and subtractive color mixing is performed. It becomes green. Therefore, the part where the blue and yellow are left means that the mixed state is bad, and the manual kneading process may be performed until it can be confirmed that the mixture 59 has a uniform green color. FIG. 9C is a diagram illustrating a state of the mixture 59 in which the hand kneading process is finished and the entire surface becomes uniform green.

[Color difference]
The color difference that occurs before and after mixing a plurality of types of liquids of the present invention will be described. The method for generating a color tone difference in the present invention is not particularly limited as long as the color tone difference can be visually recognized between the color tone of each liquid before mixing and the color tone of the mixture after mixing. Therefore, it may be a color difference due to color mixing or a color change due to reaction. Moreover, as long as mixing can be visually recognized by a color tone difference, it may be colored or colorless. For example, a mixture that becomes colorless after mixing a plurality of colored liquids may be obtained, or a mixture that becomes colored after mixing a plurality of colorless liquids may be obtained. In the present invention, it is preferable to use a method using additive color mixing and subtractive color mixing because the mixed state can be immediately recognized.

  In addition, as the color employed for the confirmation of the color tone difference of the present invention, a plurality of liquids before mixing can be clearly distinguished, and at the time of mixing, a change between the color exhibited by the mixture and the color which the plurality of liquids before mixing had It is desirable to use a color that is clearly visible. That is, in order to clarify the change in the color tone, it is preferable to adopt a color tone whose absorption wavelength is different, and it is preferable to use a color tone that can easily catch the change visually. For example, the color of the liquid before mixing can be magenta and cyan, the color of the mixture can be blue, the color of the liquid before mixing can be yellow and magenta, and the color of the mixture can be red It is. Among the color combinations, it is most preferable that the color of the liquid before mixing is blue and yellow, and the color of the mixture is green because the mixed state can be easily distinguished.

  In particular, when a plurality of types of liquids used in the present invention are used as a main component and a curing agent of a two-component curable urethane material, respectively, the main agent is toned in blue and the curing agent is toned in yellow. It is preferable. The curing agent of a two-component curable urethane material containing an amine-based crosslinking agent is originally yellowish. For this reason, making the curing agent yellow is advantageous at the time of toning in that the color tone inherent to the curing agent is utilized. On the other hand, if the main agent is toned in blue, it can be made a green mixture by subtractive color mixing when mixed with a curing agent toned in yellow, so that the color difference is expressed as a clearer color. Can do.

<Main components>
In the following, the main elements constituting the multiple liquid storage and mixing container 10 will be described in more detail.

[Color difference generator]
In the present invention, a color difference generating agent is blended as a substance that generates a color difference. The color difference generating agent used in the present invention is a pigment and / or dye having an average particle size of 0.2 μm or less, and the content thereof is 20 ppm or more and 5000 ppm or less, respectively, with respect to a plurality of types of liquids to be blended. It is blended so that it becomes. When a dye is used, it may be dissolved or dispersed in each of the plural liquids used. Moreover, when the pigment and / or dye are dispersed, the average particle diameter is preferably 0.01 μm or more and 0.15 μm or less.

  Further, a more preferable range of the average particle diameter is different between the dye and the pigment. A more preferable range of the average particle diameter when using a dye is 0.01 μm or more and 0.05 μm or less. A more preferable range of the average particle diameter when using a pigment is 0.03 μm or more and 0.1 μm or less.

  The content of the plural kinds of liquids to be blended is also different between the dye and the pigment. The range of more preferable content when using a dye is 30 ppm or more and 1000 ppm or less, and the particularly preferable range is 40 ppm or more and 500 ppm or less. The range of more preferable content when using a pigment is 100 ppm or more and 3000 ppm or less, and the particularly preferable range is 200 or more and 2000 ppm or less.

  The tone difference generating agent used in the present invention is a transparent type pigment and / or dye. The transparent type pigment and / or dye refers to a pigment and / or dye that can maintain transparency when mixed into a plurality of types of liquids to be mixed. When the pigments and / or dyes to be blended are opaque types, the hiding power is strong, so even if a small amount is mixed, the color of the liquid will change and light will be blocked regardless of the liquid depth. It is difficult to check the situation. In the case of transparent type pigments and / or dyes, the mixed liquid transmits light, so that the mixing property can be easily confirmed even when there is a liquid depth.

  The pigment and / or dye used as a color tone generator used in the present invention is not particularly limited as long as it is a transparent type that does not react with an isocyanate group (NCO group), amino group, or hydroxyl group contained in the urethane material. It is not something.

  As a transparent type pigment, for example, a product made by Dainichi Seika Kogyo Co., Ltd., trade name: Dipyroxide Side Color, etc., whose primary particle diameter is refined (controlled to 1/10 to 1/20 of the conventional product) Can be mentioned. In the present embodiment, the product name: Dipyroxide Blue # 3490: Co-Al is used to adjust the main agent to blue, and the Dipyroxide Yellow is used to adjust the curing agent to yellow. # 3150: Ti—Sb—Cr can be blended, and these transparent type pigments can be used in the form of powder or in the form of toner.

  The transparent type dye is not particularly limited as long as it does not react with the liquid material to be blended and has high solubility. For example, azo-type, carbonium-type, methine-type, anthraquinone-type and other transparent type dyes can be mentioned. Examples of commercially available transparent dyes include blue dyes manufactured by BASF, NEOZAPON Blue 807, Ayaka Chemical Co., Ltd., Oil Blue # 38, and the like. Moreover, as a transparent type yellow dye, the product made from BASF, NEOZAPON Yellow 157, the product made by Ayaka Chemical Co., Ltd., Oil Dye Yellow # 3G etc. can be mentioned.

  In the present embodiment, a blue color difference generator is used as the main agent, and a yellow color difference generator is used as the curing agent, but the amount used is small for blue and many for yellow. Preferably there is.

[Multiple types of liquid]
The multiple types of liquids stored in the multiple liquid storage and mixing container of the present invention are not particularly limited. It can select suitably according to the use used by mixing.

〔transparency〕
In the multiple liquid storage and mixing container of the present invention, the total light transmittance of each of the multiple types of liquids to be contained is usually 20% or more, preferably 30% or more, and more preferably 40% or more. desirable. Here, the total light transmittance is measured by JIS K7105-1981 (plastic engineering property test method (measurement method B)). A liquid having a total light transmittance in such a range has transparency. If a plurality of types of liquids to be mixed have transparency, the degree of mixing can be easily grasped when the liquids are mixed together.

〔viscosity〕
In the multi-liquid storage and mixing container of the present invention, the viscosities at 23 ° C. of the plurality of types of liquid are preferably 100 mPa.s, respectively. s to 8,000 mPa.s s or less, more preferably 200 mPa.s. s or more, 5,500 mPa.s s or less, most preferably 300 mPa.s. s to 4,000 mPa.s s or less.

  The viscosity at 23 ° C. is 8,000 mPa.s. If it exceeds s, mixing with a propeller or a turbine type stirring device is possible. However, manual stirring by human hands takes time to sufficiently mix multiple types of liquids, and the viscosity is high. Workability is also poor. On the other hand, if the viscosity is too low, the amount of monomer, solvent, and plasticizer will increase, and the reactivity, physical properties, and physical properties of the resulting coating will decrease. In the present invention, by setting the viscosity of a plurality of types of liquids at 23 ° C. within the above range, even when mixing by human hands such as hand massage at normal temperature, it can be carried out evenly in a short time.

[Thixotropic]
In the present invention, a thin film can be applied not only to a flat field but also to a standing surface by prescribing the thixo index after mixing to be 4 or more. For example, even in the case of roof waterproofing and flooring, there are always slopes and standing surfaces, although they are small in area, and these are usually used for standing surfaces separately from materials for flat fields. The materials are prepared. However, it is not a preferable situation from the viewpoint of work efficiency and material loss to prepare a material for a standing surface separately for repairing a small area. Therefore, if the mixture obtained from a plurality of types of liquids of the present invention has thixotropy, it can cope with not only a flat field but also a standing surface. Therefore, it is highly useful in forming a coating film on a portion having a standing surface.

  In addition, as a method for imparting thixotropy, there is also a method by adding a normal inorganic filler, but since the inorganic filler has many opaque types, the transparency of the liquid after blending cannot be maintained. Therefore, when an inorganic filler is blended as a method for improving thixotropy, difficulties arise when confirming the mixed state. In the present invention, it is desirable to employ a method capable of maintaining the transparency of a plurality of types of liquids as a method for improving thixotropy.

[Two-component curing urethane material]
When the use of the mixture obtained using the multi-liquid storage and mixing container of the present invention is a repair material, a plurality of types of liquid may be used as a main component and a curing agent of a two-component curable urethane material. preferable. In general, it is desired that the material used as the repair material is both fast curability and high physical properties. For this reason, when the liquid accommodated in the storage and mixing container for plural liquids of the present invention is used as the main component and curing agent of the urethane material, it is preferable to use the following materials.

(Main agent)
The main agent preferably used in the present invention is a urethane prepolymer containing isocyanate and / or urethane groups. Although it does not specifically limit as isocyanate used as a structural unit, For example, such as tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), xylylene diisocyanate (XDI), 1,5-naphthalene diisocyanate (NDI) Aromatic diisocyanates; aliphatic diisocyanates such as hexamethylene diisocyanate (HDI); fats such as isophorone diisocyanate (IPDI), hydrogenated tolylene diisocyanate, hydrogenated XDI (H6XDI), hydrogenated MDI (H12MDI), norbornane diisocyanate (NBDI) Cyclic diisocyanate; carbodiimide-modified and trimer-modified products of the above-mentioned various isocyanates. Moreover, in this invention, these diisocyanate may use single type and may use multiple types together as needed.

  In the present invention, among these, it is particularly preferable to use xylylene diisocyanate (XDI) or diphenylmethane diisocyanate (MDI). When xylylene diisocyanate (XDI) is used, good physical properties are exhibited even when the pot life is extended, and when diphenylmethane diisocyanate (MDI) is used, the curing rate is increased. It becomes easy.

  The content of the isocyanate group (NCO group) contained in the main agent is not particularly limited, and can be appropriately set according to the use of the mixture obtained thereafter. As a prescription in which the content of isocyanate group (NCO group) is relatively low, the prescription for waterproofing is low hardness and large elongation. In this case, the content of isocyanate group (NCO group) is 7%. Degree. On the other hand, as a prescription in which the content of isocyanate groups (NCO groups) is relatively low, it is a prescription for high-hardness flooring. In this case, the content of isocyanate groups (NCO groups) is about 20%. To do. If it is 7% or less, there is a problem that the viscosity becomes too high. On the other hand, if it is 20% or more, due to the increase in the content of free isocyanate monomer, the reactivity becomes too high and the working time is increased. There arises a problem that cannot be taken sufficiently.

[Curing agent]
When the plurality of types of liquids used in the present invention are a main component and a curing agent of a two-component curable urethane material, the curing agent used is a mixture containing a compound containing active hydrogen and a polyol.

  Although it does not specifically limit as a compound containing the active hydrogen contained in the hardening | curing agent used for this invention, For example, an amine type crosslinking agent can be used preferably. Specific examples of the amine-based crosslinking agent include aromatics such as 4,4′-methylenebis (2-orthochloroaniline) (MBOCA), diethyltoluenediamine (DETDA), dithiomethyltoluenediamine (E-300), and methylenedianiline. Group diamine compounds can be mentioned. Among these, a mixture of 4,4'-methylenebis (2-orthochloroaniline) (MBOCA) and a polyol is preferable because it shows good results when combined with the above main agent.

  The polyol contained in the curing agent used in the present invention is not particularly limited, and examples thereof include relatively low molecular weight polyhydric alcohols, polyether polyols, polyester polyols, and modified products thereof. it can.

  Specific examples of relatively low molecular weight polyhydric alcohols include ethylene glycol (EG), diethylene glycol (DEG), propylene glycol (PG), dipropylene glycol (DPG), 1,3-butanediol (1,3 -BD), 1,4-butanediol (1,4-BD), 4,4′-dihydroxyphenylpropane, dihydric alcohols such as 4,4′-dihydroxymethylmethane; glycerin, 1,1,1-tri Examples thereof include trihydric alcohols such as methylolpropane (TMP) and 1,2,5-hexatriol; and polyhydric alcohols such as pentaerythritol, glucose, sucrose, and sorbitol.

  Specific examples of polyether polyols include addition polymerization of one or more of ethylene oxide, propylene oxide, butylene oxide and the like to one or more of the above-mentioned relatively low molecular weight polyhydric alcohols. Polytetramethylene ether glycol (PTMEG) obtained by ring-opening polymerization of polyether polyol and tetrahydrofuran.

  Specific examples of polyester polyols include ethylene glycol, propylene glycol, butanediol, pentanediol, hexanediol, glycerin, trimethylolpropane, and one or more other low molecular weight polyols, glutaric acid, and adipic acid Polyester polyols obtained by condensation polymerization with one or more of sebacic acid, terephthalic acid, isophthalic acid, dimer acid, or other low molecular dicarboxylic acid or oligomeric acid, and ring-opening polymerization of caprolactone, etc. Can be mentioned.

  Specific examples of modified products of polyether polyols or polyester polyols include polymer polyols obtained by graft polymerization of the above-described polyether polyols or polyester polyols with ethylenically unsaturated compounds such as acrylonitrile, styrene and methacryl methacrylate. Etc. In addition, a castor oil derived from a natural product, a hydroxyl group-containing polybutadiene, a hydroxyl group-containing polyisoprene, or a hydrogenated product thereof can also be used.

  Among these, the polyol that is particularly preferably used in the curing agent of the present invention is a bifunctional or trifunctional polyether polyol. If it is a bifunctional or trifunctional polyether polyol, it will not become a solid at room temperature, so the viscosity of the liquid is preferable. The molecular weight of the bifunctional or trifunctional polyether polyol can be appropriately selected depending on the hardness of the cured product obtained thereafter.

  The mixing ratio of the amine crosslinking agent and the polyol (amine crosslinking agent / polyol) in the curing agent used in the present invention is preferably an equivalent ratio in the range of 95 to 40/5 to 60. When the compounding ratio of the amine cross-linking agent exceeds 95 equivalents, the cured product becomes hard and does not exhibit rubber elasticity. On the other hand, when it is less than 40 equivalents, it becomes difficult to maintain a balance between reactivity and physical properties.

[Reactive thixotropic agent]
When the two or more types of liquids used in the present invention are the main component and the curing agent of the two-component curable urethane material, by adding a reactive thixotropic agent to the curing agent used, the resulting mixed liquid Thixogenicity can be expressed.

  If the liquid mixture has thixotropy, it can be applied to the standing surface, and a certain film thickness can be applied to the standing surface simultaneously with the construction of the flat place. For repairing walls, bridges, stairs, and anticorrosion / rust prevention, a material that does not sag is desired. Therefore, a formulation with a high thixo index (6 or more) is preferable. In addition, in combination with a flat field, a slightly lower thixo index (about 4 to 6) is preferable in order to give a film thickness of about 1 mm to the standing surface. In the present invention, by containing a reactive thixotropic agent, a higher thixo index (about 20) as required for a sealing material can be expressed.

  As a method for developing thixotropy, addition of an organic reactive thixotropic agent is effective. Specifically, in the curing agent, aliphatic diamine and / or alicyclic diamine is 0.03 equivalents or more and 0.4 equivalents or less, preferably 0.05 equivalents or more and 0.3 equivalents or less with respect to the isocyanate group. More preferably, it is desirable to blend 0.1 equivalents or less and 0.2 equivalents or less. By containing an aliphatic diamine and / or an alicyclic diamine in the curing agent in the above range, a thixotropy having a thixo index of 4 or more can be expressed in the resulting mixture. If the blending amount is less than 0.03 equivalent, thixotropy will be insufficiently expressed. On the other hand, when it exceeds 0.4 equivalent, thixotropy becomes too strong and mixing by hand is difficult, and physical properties of the resulting mixture are greatly reduced.

  Specific examples of the aliphatic diamine and / or alicyclic diamine include, for example, 2,5 (6) -diaminobicyclo [2,2,1] heptane (NBDA), 2-aminomethyl-5 (6) -amino. Ethylbicyclo [2,2,1] heptane, 2-aminomethyl-5 (6) -aminopropylbicyclo [2,2,1] heptane, 2-aminomethyl-5 (6) -aminobutylbicyclo [2,2 , 1] -heptane, 2,5 (6) -diaminoethylbicyclo [2,2,1] heptane, 2,5 (6) -diaminopropylbicyclo [2,2,1] heptane, 2,5 (6) -Diaminobutylbicyclo [2,2,1] heptane, 2,5 (6) -diaminopentylbicyclo [2,2,1] heptane, 5 (6) -diaminoaminomethylbicyclo [2,2,2] octane, 2-amino Tyl-5 (6) -aminoethylbicyclo [2,2,2] octane, 2-aminomethyl-5 (6) -aminopropylbicyclo [2,2,2] octane, 2-aminomethyl-5 (6) -Fuminopropylbicyclo [2,2,2] octane, 2-aminomethyl-5 (6) -aminopentylbicyclo [2,2,2] octane, 2,5 (6) -aminoethylbicyclo [2,2, 2] octane, 2,5 (6) -diaminopropylbicyclo [2,2,2] octane, 2,5 (6) -diaminobutylbicyclo [2,2,2] octane, 2,5 (6) -diamino Pentylbicyclo [2,2,2] octane, 3 (4), 8 (9) -diaminomethyltricyclo [5,2,1,02,6] decane, 3 (4) -aminomethyl-8 (9) -amino Ethyltricyclo [5,2 1,02,6] decane, 3 (4) -aminomethyl-8 (9) -aminopropyltricyclo [5,2,1,02,6] decane, 3 (4) -aminomethyl-8 (9) -aminobutyltri Cyclo [5,2,1,02,6] decane, 3 (4) -aminomethyl-8 (9) -aminopentyltricyclo [5,2,1,02,6] decane, 3 (4), 8 (9 ) -Diaminoethyltricyclo [5,2,1,02,6] decane, 3 (4), 8 (9) -diaminopropyltricyclo [5,2,1,02,6] decane, 3 (4) , 8 (9) -diaminobutyltricyclo [5,2,1,02,6] decane, 3 (4), 8 (9) -diaminopentyltricyclo [5,2,1,02,6] decane, 3 (4), 7 (8) -Diaminomethylbicyclo [4,3,01,6] nonane 3 (4) -Aminomethyl-7 (8) -aminoethylbicyclo [4,3,01,6] nonane, 3 (4) -aminomethyl-7 (8) -aminopropylbicyclo [4,3,01 , 6] nonane, 3 (4) -aminomethyl-7 (8) -aminobutylbicyclo [4,3,01,6] nonane, 3 (4) -aminomethyl-7 (8) -aminopentylbicyclo [4]. , 3,01,6] nonane, 3 (4), 7 (8) -diaminoethylbicyclo [4,3,01,6] nonane, 3 (4), 7 (8) -diaminopropylbicyclo [4,3 , 01,6] nonane, 3 (4), 7 (8) -diaminobutylbicyclo [4,3,01,6] nonane, 3 (4), 7 (8) -diaminopentylbicyclo [4,3,01] , 6] nonane, 3-aminomethyl-3,5,5-trimethylcyclohexane Silamine (IPDA, also known as isophorone diamine), 1,2-diaminocyclohexanone, 1,3-diaminocyclohexane, 1,4-diaminocycloxanone, triethylene diamine, hexamethylene diamine, and polyether amine in which polyol hydroxyl group is aminated Can be mentioned.

<Example 1>
[Storage of multiple liquids and production of mixing containers]
A cylindrical film having a width of 150 mm and having an outer surface made of oriented nylon sheet (15 microns) and an inner side made of polyethylene (80 microns) was cut into a length of 300 mm. Subsequently, using a heat sealer, heat sealing was performed so that the shape of both end portions was a round shape (corner cut) having no corners. Next, a partition plate was attached to the middle part of the film and divided into two independent spaces. The independent space formed on one side was filled with the main agent A1 (200 g) using a double pipe while flowing carbon dioxide gas, and heat-sealed in a state where no gap was generated inside. Since care was taken to prevent the main agent from sticking to the heat seal surface, there was a slight gap (carbon dioxide gas) left inside the bag. However, with the passage of time, the carbon dioxide gas was absorbed into the liquid and the voids disappeared. Similarly, curing agent B1 (200 g) was filled in the independent space on the other side, and heat sealing was performed in the same manner as the main agent. In this case as well, a void remained at the beginning, but the void disappeared over time. The NCO index at this time was 1.1. Next, the storage / mixing container filled with the main agent and the curing agent was placed in another bag in order to block moisture and ensure strength. The material of the bag retains strength and moisture resistance. From the outside, a laminated bag of PET / nylon / aluminum / PE is used, and a silica gel moisture absorbent is placed inside, and after nitrogen sealing, the opening is heat sealed. did.

[Preparation of mixture]
After removing the partition plate provided in the middle part and making two independent spaces into one merged space, mixing was performed by holding the whole with both hands. The mixture of the main agent (blue) and the curing agent (yellow) is such that the viscosity of the main agent A1 is 3000 mPa.s. s, the viscosity of the curing agent B1 is 4500 mPa.s. Since both had low viscosity, it was not necessary to use a stirrer, and mixing was possible only by squeezing by hand.

  Moreover, as for the main ingredient (A1) and the hardening | curing agent (B1), since the transparent type dye was mix | blended in all, the part in which two liquids were mixed discolored green transparently. For this reason, it was possible to grasp the mixed state at a glance and to mix without leaving an unmixed part.

  Furthermore, since the shape of the merged space formed for mixing did not have corners, the mixture of the two liquids turned green as a whole by squeezing by hand for about 30 seconds. The total light transmittance of this mixture was 47%, and the transparency was maintained even after mixing the two liquids. In the case of a container having a corner portion, an unmixed portion remains in the corner portion. In this example, a uniform mixture could be obtained without leaving the unmixed portion in about 30 seconds. .

[Application of mixture]
Further, after squeezing by hand for 30 seconds, the bag was opened, and the mixed solution was applied to the repaired part (the part where the urethane flooring was damaged) using a trowel.

[Application to standing surface]
Since this formulation contains a highly reactive aliphatic amine (IPDA), a thixo index (a viscosity ratio of 0.6 rpm / 6 rpm using a B-8M type rotational viscometer) after 2 minutes of mixing is 5 Was showing. For this reason, even when applied to the standing surface portion, a thickness of about 1 mm could be secured.

[Application to flat ground]
At the same time, the coating was applied to the flat field. Since the viscosity of the mixed two liquids was low, the fluidity was maintained even when the mixture was used, and it could be easily stretched. Moreover, the surface of the obtained coating film became a smooth surface. Therefore, the repair could be completed in a short time.

[Application of top coat]
The fluidity disappeared after about 4 minutes (pot life: PL), and after 1 hour, a top coat could be applied to the surface.

[Physical properties of cured product]
The physical properties of the cured product obtained from the mixture are: hardness (Hs) 82A, tensile strength (TS) 5.2 Mpa, elongation (EL) 270%, tear strength (TR) 39 N / mm, and good for use as a flooring The physical properties were shown. Table 3 shows the implementation formulation and various physical properties.

<Example 2>
[Storage of multiple liquids and production of mixing containers]
Using A2 as the main agent and B2 as the curing agent, a storage and mixing container was produced in the same manner as in Example 1 while flowing carbon dioxide using a double pipe. The internal voids disappeared over time. The NCO index at this time was 1.1.

[Preparation of mixture]
In this example, a transparent pigment was used for both the main agent (A2) and the curing agent (B2). However, as with the transparent dye of Example 1, the mixed state of the mixed liquid can be accurately grasped, and bubbles are also generated. It was not contained, and the whole could be uniformly mixed in a short time without leaving an unmixed part.

[Application of mixture]
The material viscosity of this product is 700 mPa.s for the main agent (A2). s, the curing agent (B2) is 2,700 mPa.s. In addition to the low viscosity and s, the pot life (PL) was as long as 10 minutes, so the workability was very good. When used for repairing the roof-top waterproofing material with a parapet shape, it was easy to install on the ground as well as on the flat. The film thickness was 2 mm at the flat place and 1 mm at the elevation. Table 3 shows the implementation formulation and various physical properties.

<Example 3>
[Storage of multiple liquids and production of mixing containers]
Using A5 as the main agent and B5 as the curing agent, and using the same cylindrical film as in Example 1, heat is applied so that the shape of the space filled with a plurality of types of liquid becomes elliptical (see FIG. 5C). Sealing was performed. Next, the middle part on both sides of the obtained container was heat-sealed at a low temperature, and the liquid could be completely sealed, but heat-sealed to such an extent that it could be easily peeled off, and a lateral seal with a width of 10 mm was performed. . Subsequently, 250 g each of the main agent (A5) and the curing agent (B5) were filled from the openings (filling ports) on both sides in the same manner as in Example 1 while flowing carbon dioxide using a double pipe. A storage and mixing container was obtained. The NCO index at this time was 1.1.

[Preparation of mixture]
In adjusting the mixture, the middle seal could be easily removed by pulling both ends. As in Example 1, the entire color turned green in 30 seconds, and the liquid could be completely homogenized by continuing mixing for 30 seconds.

[Application of mixture]
Since this mixture does not contain any reactive thixo, the thixo index was 1. For this reason, the liquid mixture was in a smooth state, and when surface coating was applied about 2 mm for repairing the veranda, the surface smoothness was very good. Table 3 shows the implementation formulation and various physical properties.

<Example 4>
[Storage of multiple liquids and production of mixing containers]
As a storage and mixing container, a sheet having an oriented nylon (15 μm) as an outer layer and an ionomer resin (manufactured by Tamapoly Co., Ltd., trade name: HM-07, 80 μm) as an inner layer is used. A bag was made. Subsequently, A6 as a main agent and B6 as a curing agent were filled, and a storage and mixing container was produced in the same manner as in Example 1. When filling, a normal nozzle was used without using a sealing gas, and during heat sealing, the gap was completely eliminated, and the liquid was thinly sealed at the portion adhering to the bag (contamination seal). For this reason, there were no voids inside, and it was not necessary to use nitrogen or carbon dioxide. Since the ionomer is used for the inner layer, the melting point is lowered, and the main agent and the curing agent adhering to the film can be pushed away to be able to seal, so there was no problem in the adhesiveness. The NCO index at this time was 1.1.

[Preparation of mixture]
This mixture contains a lot of reactive thixotropic agent, so the viscosity at the time of mixing is slightly high, but it can be mixed well by human hands, and there is no void inside when mixing, so there are no bubbles and good It was a result. Normally, a “vacuum mixer” is required to mix a high thixo product without containing bubbles, but it has been found that a thixo product can be easily produced according to the method of the present invention.

[Application of mixture]
When mixed for 60 seconds, the thixo index was as high as 8. When applied to the standing surface, a thickness of about 3 mm could be secured. For this reason, this mixture was able to be used as a wall surface repair or a rubber chip binder. In particular, when used as a rubber chip binder, since the binder adheres to the rubber surface, the physical properties of the surface layer were improved as compared with a normal fluid type (thixo index: about 1). Table 3 shows the implementation formulation and various physical properties.

<Example 5>
[Storage of multiple liquids and production of mixing containers]
As a storage and mixing container, Example 1 was used using a sheet in which oriented nylon (15 μm) as an outer layer and EVA resin (manufactured by Tamapoly Co., Ltd., trade name: SB-5; containing VA 5%, 80 μm) as an inner layer were bonded. A bag having the same shape was produced. Subsequently, a storage and mixing container was produced in the same manner as in Example 4 except that A8 was used as the main agent and B8 was used as the curing agent. There were no voids inside, and there was no problem with adhesiveness. The NCO index at this time was 1.1.

[Preparation of mixture]
Since this mixture did not contain a reactive thixotropic agent, it was extremely easy to mix and could be easily mixed by hand.

[Application of mixture]
This mixture has high hardness due to the high NCO%, and is therefore optimal for repairing high-hardness flooring. Table 3 shows the implementation formulation and various physical properties.

<Example 6>
[Storage of multiple liquids and production of mixing containers]
A storage and mixing container was produced in the same manner as in Example 5 except that A9 was used as the main agent and B9 was used as the curing agent. The NCO index at this time was 1.1.

[Preparation of mixture]
This mixture contained 0.1 equivalent ratio of reactive thixotropic agent, but could be easily mixed.

[Application of mixture]
This mixture was able to give a uniform thickness even when applied to a veranda with a rain gradient, and was optimal for waterproofing. Table 3 shows the implementation formulation and various physical properties.

<Comparative Example 1>
[Storage of multiple liquids and production of mixing containers]
A bag similar to that of Example 1 was produced except that A3 (colorless and transparent) was used as the main agent and B3 (light yellow and transparent) was used as the curing agent. A mixing vessel was manufactured. When the liquid adheres to the heat seal surface, the welded sealability is poor, so care was taken, but the solution was filled with a gap left. The NCO index at this time was 1.1.

[Preparation of mixture]
Since the main agent (A3) is colorless and transparent, and the curing agent (B3) is light yellow and transparent, it was difficult to determine whether the two liquids were mixed. Moreover, since there existed a space | gap in a main ingredient and a hardening | curing agent and the small bubble disperse | distributed to the whole when it mixed, it became a mixture containing a bubble.

[Application of mixture]
The mixture was applied on a mold to a thickness of 2 mm, and the physical properties of the obtained sheet were tested. Since the unmixed main agent is scattered everywhere, the sheet itself is sticky, and the blending ratio is different, only about half the strength can be expressed compared to the mixture obtained in the example. There wasn't. In addition, since it contained bubbles, the bubbles floated on the surface of the sheet, resulting in irregularities, which not only looked bad but also deteriorated in physical properties. Table 4 shows the implementation formulation and various physical properties.

<Comparative example 2>
[Storage of multiple liquids and production of mixing containers]
The same bag as in Example 1 was manufactured except that A4 (blue opaque) was used as the main agent and B4 (yellow opaque) was used as the curing agent, and sealing was performed with liquid on the sealing surface so that no voids were formed. (Contamination seal) was performed to produce a storage and mixing container. However, since there is a portion where the liquid adheres to the sealing surface, the sealing performance is poor and the liquid is blotted. The NCO index at this time was 1.1.

[Preparation of mixture]
All of the liquids are opaque liquids due to opaque pigments, so they have high light shielding properties. Even if they are slightly attached, they change color when attached to the inner surface of the bag, and it is difficult to determine whether they are mixed. In addition, the amount of liquid oozing out due to the pressure applied at the time of mixing was distorted, and the mixing ratio was distorted, and the exuded main agent and curing agent adhered to the hands, so workability and hygiene were significantly reduced.

[Application of mixture]
In the same manner as in Comparative Example 1, the mixture was applied on a mold to a thickness of 2 mm, and the physical properties of the obtained sheet were tested. The sheet was sticky and only about half the strength of the mixture obtained in the examples could be developed. Table 4 shows the implementation formulation and various physical properties.

<Comparative Example 3>
[Storage of multiple liquids and production of mixing containers]
A bag similar to that of Example 1 was produced except that A7 (blue opaque) was used as the main agent and B7 (yellow opaque) was used as the curing agent, and the main agent and the curing agent were filled with a single tube nozzle. In order to remove the moisture, a storage and mixing container was manufactured by purging with nitrogen gas and then heat sealing. However, because the moisture in the voids could not be removed completely, gels produced by reaction were generated inside the main agent over time even under absolutely dry conditions. The NCO index at this time was 1.1.

[Preparation of mixture]
All liquids have a viscosity of 5000 mPa.s. Since it was more than s, the viscosity was high and mixing by hand was difficult. For this reason, even if it mixed for 60 seconds, it was in the condition where it was not mixed yet. In addition, since any liquid is an opaque liquid due to the opaque pigment, it is difficult to check the mixed state by blocking light. For this reason, the mixing time was 120 seconds.

[Application of mixture]
In the same manner as in Comparative Example 1, the mixture was applied on a mold to a thickness of 2 mm, and the physical properties of the obtained sheet were tested. The cured sheet remained sticky and the physical properties obtained were not satisfactory. Table 4 shows the implementation formulation and various physical properties.

<Comparative example 4>
[Storage of multiple liquids and production of mixing containers]
Using A2 (blue transparent) as the main agent and B2 (yellow transparent) as the curing agent, and using the same cylindrical film as in Example 4, the shape of the space filled with a plurality of types of liquids is used to round the corners. It was used with the corners left without sealing. Next, the middle part on both sides of the obtained container was heat-sealed at a low temperature, and the liquid could be completely sealed, but heat-sealed to such an extent that it could be easily peeled off, and a lateral seal with a width of 10 mm was performed. . Subsequently, in the same manner as in Example 1, 250 g each of the main agent (A2) and the curing agent (B2) are filled from the openings (filling ports) on both sides, and no gaps remain in the interior by performing a random seal. A storage and mixing container was obtained. The shape from the front of the independent space containing the main agent (A2) and the curing agent (B2) was a rectangle having corners,

[Preparation of mixture]
When the two liquids were mixed, they were rubbed by hand, but no bubbles were mixed in, but the liquids remained in the four corners, and it was difficult to mix the liquids. Even after 120 seconds, the corners were not completely green, and the main agent blue and the curing agent yellow remained.

[Application of mixture]
In the same manner as in Comparative Example 1, the mixture was applied on a mold to a thickness of 2 mm, and the physical properties of the obtained sheet were tested. In the sheet, an unmixed portion partially remained, the variation in physical properties was large, and the strength was about half that of the example. Table 4 shows the implementation formulation and various physical properties.
