[Industrial applications]

 The present invention relates to a material for a cosmetic material, and more particularly to a material for a cosmetic material in which a cosmetic material processing maker simply produces a cosmetic material by printing, foaming treatment, embossing treatment or the like on the surface thereof.

Various types of decorative materials are attached to the ceiling and wall surfaces of buildings, various home appliances, cosmetic boxes, interiors of automobiles, etc. in order to enhance their design. In the present invention, wallpaper will be described below as a typical example of the decorative material. In recent years, as the demand for housing has expanded, the use of wallpaper as an interior decoration material has been rapidly increasing. Along with this, the demands of customers have diversified, and various functional wallpapers have been provided. The decorative layer formed on the surface of the wallpaper is provided mainly for the purpose of imparting durability and design to the wallpaper. A foamable or non-foaming vinyl chloride resin paint is applied on the surface of the base paper in an amount of 100 to 200 g. / M ^{2 The} most examples are coating. Conventionally, a calendar method, a reverse roll coater method, a gravure printing method, a rotary screen printing method and the like have been used for coating the decorative layer.

On the other hand, a base paper for wallpaper (backing paper) is indispensable for the production of wallpaper, and a large amount of base paper having flame retardancy is used. In order to give flame-retardant properties to the base paper, there are some examples where the base paper contains a large amount of inorganic filler (backing paper for inorganic wallpaper) or the base paper is impregnated with a flame retardant (backing paper for vinyl wallpaper). Mostly. For example, the technique described in JP-A-3-161598 filed by the present applicant is applied to wallpaper base paper containing an inorganic filler in an amount of 80% by weight or more based on the base paper and further imparted with peelability.

On the other hand, recently, the number of concrete buildings has increased and the airtightness of a room has been improved, so that it is a problem that dew condensation easily occurs on the wall surface. In addition, the wallpaper with a large amount of vinyl chloride resin coated on the surface as described above will generate a large amount of chlorine gas and smoke when discarded and burned, and plasticizers such as DOP will be generated during landfill disposal. Problems such as elution into the ground and pollution of the environment have been pointed out. The amount of heat generated when the wallpaper burns, the amount of smoke emitted, and the amount of generated gas and its type vary greatly depending on the content of cellulose fiber and flame retardant in the base paper, the amount of resin in the decorative layer and its type. . For this reason, so-called "human and earth-friendly" wallpapers are being developed that use a resin other than vinyl chloride resin with the thickness of the decorative layer as small as possible. For example, a technique for forming a decorative layer mainly composed of an aqueous synthetic resin emulsion on a base paper has been studied and disclosed in JP-A-4-126239 and JP-A-4-126240.

[0005] There are unique difficulties in producing a wallpaper that forms a decorative layer mainly composed of a water-based synthetic resin. This is because the cellulose fiber (pulp fiber), which is a component of the base paper, is hydrophilic, and the cellulose fiber swells under the influence of water when the water-based resin is applied. . For example, when the base paper for wallpaper containing a large amount of the inorganic filler described in JP-A-3-161598 described above is coated with a coating liquid prepared by mixing an aqueous synthetic resin emulsion, a foaming agent, an inorganic filler, etc., the base paper is coated. Non-uniform expansion and contraction causes a sheet waviness phenomenon (hereinafter referred to as "waviness phenomenon"). This is a fatal defect in the wallpaper manufacturing process.

In order to solve the disadvantage that the cellulose fibers swell, in JP-A-4-126240, polyvinyl chloride, polyethylene, polypropylene, polyurethane, polyamide, at least on the surface of the backing paper (base paper) on which the decorative layer is formed, A 5 to 30 g / m ² "water-impermeable synthetic resin coating layer" of polyester, synthetic rubber, acrylic resin, etc. is formed, and this layer prevents water from permeating into the base paper when the water-based resin is applied. As a result, proposals have been made to solve the "waviness phenomenon" of the base paper.

However, as a result of the study by the present inventors, this method can prevent the “waviness phenomenon” that occurs when coating the water-based synthetic resin, but the water vapor generated during the drying and foaming processes. Air, foaming gas, etc. have no escape in the direction of the thickness (Z) of the base paper, causing a "blister phenomenon" in the decorative layer, or foaming gas causes the foamed resin layer to rise from the coating layer. It turned out that "a phenomenon" occurs. If this phenomenon occurs, adhesion between the base paper and the decorative layer will be poor and the durability and commercial value of the wallpaper will be significantly reduced, which is a fatal problem.

On the other hand, as wallpaper, a wallpaper manufacturer purchases a wallpaper base paper mainly manufactured by a paper manufacturing company, and as described above, the base paper is coated with a coating solution in which a foaming agent and an inorganic filler are mixed with a resin. It is manufactured through coating, printing, foaming, embossing, etc. This method inevitably requires a coating liquid preparation facility and a coating liquid coating device. In addition, this method was suitable for the production of large-scale wallpaper in consideration of productivity, and was not suitable for the production of small-lots.

[0009]

[Problems to be solved by the device]

 The present invention aims to solve these drawbacks. That is, even if a non-foamed water-based resin is applied as a makeup layer, the "waviness phenomenon" does not occur on the base paper during coating, and the "blister phenomenon" or "floating phenomenon" of the makeup layer occurs during the drying or foaming process. To obtain a material for cosmetics that does not cause the problem, to save labor and reduce costs for manufacturers of cosmetics, and to obtain a material for cosmetics that is also suitable for the production of small lots. .

[0010]

[Means for Solving the Problems]

As a result of earnest research, the inventors of the present invention have developed a new material for cosmetic materials that solves these problems. The gist of the present invention will be described with reference to the drawings. FIG. 1, FIG. 2 and FIG. 3 are partially enlarged sectional views of the material for decorative material of the present invention. According to the present invention, a base material 1 is provided with a filler coating layer 2 on the back side and a moisture permeable filler coating layer 3 on the front side, and the water vapor permeability in this state is 1500 to 7000 g / m ² · 24 hours, and A material for a decorative material (Fig. 1) characterized in that an unfoamed water-based resin coating layer 5 is provided on the surface, and further, a filler coating layer 2 on the back side of the base paper 1 and moisture permeability on the surface. The filler coating layer 3 and the moisture permeable resin coating layer 4 are sequentially provided, the moisture vapor transmission rate in this state is 1500 to 7000 g / m ² · 24 hours, and the surface thereof is an unfoamed water-based resin coating. It is a material for a decorative material (FIG. 2) characterized in that a layer 5 is provided, and further, a filler coating layer 2 on the back surface of the base paper 1, a moisture permeable resin coating layer 4 on the surface, and a moisture permeability. filler coating layer 3 is sequentially provided, the moisture permeability of this state is 1500~7000g / m ² · ² 4 hours, or It is decorative material for the material, wherein (3) the aqueous resin coating layer 5 unfoamed on its surface is provided.

The base paper 1 used in the present invention is mainly composed of cellulose fibers, and if necessary, synthetic fibers, inorganic fibers, synthetic pulp and the like are appropriately blended, and a self-extinguishing filler, other fillers, and a dry paper strengthening agent. It is obtained by appropriately adding a wet paper strength enhancer, a coloring agent, a sizing agent, a fixing agent and the like to make a paper.

Cellulose fibers used in the present invention include wood pulp such as softwood bleached kraft pulp (NBKP), hardwood bleached kraft pulp (LBKP), softwood bleached sulphite pulp (NBSP) and thermomechanical pulp (TMP). Mainly, it means an appropriate mixture of gin-skin fibers such as hemp, gully, and goose, and non-wood pulp such as cotton linter, bamboo, and straw. In the present invention, if necessary, synthetic materials such as vinylon, nylon, polyester, etc., glass fibers, inorganic fibers such as rock wool, and fibrous materials such as synthetic pulp may be appropriately added to these cellulose fibers alone or in a mixture. it can.

The base paper is made by a conventionally known method. That is, the normal freeness is 350 to 630 ml C.I. S. F. Then, using a cylinder paper machine or a Fourdrinier paper machine, a base paper having a basis weight of usually 60 to 200 g / m ² is produced.

It may be preferable for the base paper to be flame-retardant considering its application. Any conventionally known method can be adopted as a method for making the base paper flame-retardant. That is, a method of incorporating a large amount of a self-extinguishing filler such as aluminum hydroxide during papermaking of the base paper, a method of impregnating the base paper with a flame retardant such as guanidine sulfamate, and a method of coating the base paper with a self-extinguishing filler. And combinations of these.

In the present invention, the filler coating layer 2 is provided on the back surface of the base paper 1 thus manufactured. This layer is a layer that allows only the water content of the paste solution to penetrate into the base paper layer during the sizing operation during the application of the decorative material.When the water is absorbed, the decorative material becomes soft and can be rolled, stretched, or cornered. Easy to install. When the paste penetrates into the base paper layer, the strength of the base paper layer between the base papers increases and the peelability is impaired, so that this layer plays a particularly important role when it is used for wallpaper. Further, by providing this layer, opacity and flame retardancy are also improved.

The filler coating layer 2 is required to have appropriate water resistance, and is mainly composed of a filler and a binder, and is applied to the base paper 1 using a coating machine such as an air knife coater or a blade coater. Coated. The blending ratio of the filler and the binder is preferably about 10 to 25 parts by weight in terms of solid content of the binder with respect to 100 parts by weight of the filler. If it is less than 10 parts by weight, the required strength of the coating layer cannot be obtained, and if it exceeds 25 parts by weight, the water permeability is adversely affected. At this time, a dispersant, a water-proofing agent, a coloring agent, an antifungal agent and the like can be used in combination. The coating amount is preferably 7 to ²⁰ g / m ² , and if it is less than this, the penetration of the paste cannot be prevented, and if it is too large, the penetration preventing effect does not change.

A moisture-permeable filler coating layer 3 is provided on the surface of the base paper 1. This layer may be provided alone as shown in FIG. 1, or as shown in FIG. 3, a moisture-permeable resin coating layer may be provided beforehand. It may be provided on top of 4. Further, as shown in FIG. 2, a moisture-permeable resin coating layer 4 can be further provided on the moisture-permeable filler coating layer 3. The water vapor transmission rate of the base paper after providing these layers needs to be within a specific range (1500 to 7000 g / m ² · 24 hours), and this is the greatest feature of the present invention. In the present invention, the water vapor transmission rate means a value measured for 24 hours under the condition B (90% RH at 40 ° C.) according to the cup method specified in JIS-Z0208. By setting the water vapor permeability within this range, the above-mentioned "waviness phenomenon", "blister phenomenon" and "floating phenomenon" can be completely prevented.

The filler coating layer 2 and the moisture-permeable filler coating layer 3 are obtained by coating a coating liquid mainly containing a filler and a binder. At this time, the flame retardancy can be enhanced by using a coating liquid mainly composed of a self-extinguishing filler and a binder. As the self-extinguishing filler, any of aluminum hydroxide, magnesium hydroxide, calcium aluminate, calcium hydroxide, dawsonite, calcium aluminate and the like can be used, but the use of aluminum hydroxide is effective. Therefore, it is preferable. As the binder, a synthetic rubber latex such as SBR or MBR, an acrylic emulsion, a vinyl chloride emulsion, a vinylidene chloride emulsion, a copolymer emulsion of these, casein, starch, PVA and the like are appropriately combined and used. A self-extinguishing filler alone or by adding a dispersant to two or more kinds of fillers and then dispersing it to prepare a coating liquid, in which case a flame retardant, a filler such as titanium dioxide, a water retention agent, a fluidity If necessary, improvers, fungicides, preservatives, colorants and the like can be added.

The moisture-permeable filler coating layer 3 is a subbing layer of the unfoamed water-based resin layer 5 that is a decorative layer, and provides the adhesive force between the unfoamed water-based resin layer 5 and the moisture-permeable filler coating layer 3. It works to enhance (anchoring effect). It also works to prevent "waviness". The coating liquid material used is the same as the material of the filler coating layer 2 described above, but the blending ratio of the binder and the coating amount have a great influence on the moisture permeability, the water resistance and the size property. The blending ratio of the filler and the binder is preferably in the range of about 25 to 60 parts by weight in terms of solid content with respect to 100 parts by weight of the filler. If the amount is less than 25 parts by weight, the sizing degree and water resistance of the coating layer are poor, and a "waviness phenomenon" occurs when coating the unfoamed water-based resin, making commercialization difficult. If the amount exceeds 60 parts by weight, the size and water resistance are improved, but the water vapor transmission rate of the base paper is 1500 g / m ² · 24 hours or less, which occurs in the drying / foaming process after coating the water-based synthetic resin. There will be no escape area for water vapor, air, or foaming gas, and "blister phenomenon" or "floating phenomenon" will occur and the product will not be produced. Further, the coating amount is preferably 10 to 30 g / m ^2, less a moisture permeation degree than 10 g / m ² becomes 7000g / m ² · 24 hours or more, "waving" is generated for the same reason as described above If it exceeds 30 g / m ² , the water vapor permeability becomes 1500 g / m ² · 24 hours or less, resulting in a problem.

In the present invention, in order to further improve the anchoring effect, fillers having different particle diameters are mixed, and silica gel, synthetic silica, activated clay, calcium silicate or the like having a large specific surface area due to the structure are used. Can also be used together.

In the present invention, in order to further stabilize the sizing degree and water resistance, as shown in FIG. 2, the moisture permeable resin coating layer 4 can be provided on the moisture permeable filler coating layer 3. This depends on the type of binder used, but the coating amount is 1-5 g / m ² Is preferred. With such a coating amount, there is no risk of completely covering the surface of the moisture-permeable resin coating layer 4 and 5 g / m²When it is above, the water vapor transmission rate is 1500g / m²・ Less than 24 hours, 1g / m²The same applies below for 7,000 g / m²・ It will be over 24 hours and the above problems will occur.

The cosmetic material of the present invention can also be configured as shown in FIG. In this case, the above-mentioned filler coating layer 2 is provided on the back surface of the above-mentioned base paper, and the moisture-permeable resin coating layer 4 and the moisture-permeable filler coating layer 3 are sequentially provided on the front surface, and the moisture permeability of the obtained coated paper is increased. Of 1500 to 7000 g / m ² · 24 hours.

In the present invention, an unfoamed aqueous resin coating layer 5 is further provided on the surface thereof. As the water-based resin, one or more kinds of various synthetic resin emulsions such as acrylic emulsion, ethylene vinyl acetate emulsion, acrylic vinyl chloride emulsion, urethane emulsion, etc. are used, in which heat-foaming microspheres and Alternatively, a coating liquid containing an organic foaming agent, a coloring agent, a defoaming agent, a fluidity improving agent, etc., and mixed with titanium dioxide, calcium carbonate, a self-extinguishing filler, etc. for improving opacity and flame retardancy. 20 to 250 g / m ^{2 is} applied as a solid component and dried. Thermally expandable microspheres are disclosed in U.S. Pat. No. 2,797,201, Japanese Patent Publication No. 42-6524, Japanese Patent Publication No. 44-7344, and the like. A copolymer of methacrylic acid and styrene, acrylonitrile and styrene are disclosed. A foaming agent such as butane gas is included in resin particles such as a copolymer or vinylidene chloride. In the present invention, it is preferable to use these heat-foamable microspheres as a foaming agent because they are easy to handle. The foaming temperature is usually 100 to 200 ° C, preferably 120 to 170 ° C. If the foaming temperature is lower than 100 ° C, the drying efficiency of the unfoamed water-based resin coating layer 5 and the printing layer to be described below deteriorates, and if it exceeds 200 ° C, problems such as discoloration easily occur.

Next, a typical formulation example of the coating liquid for the unfoamed aqueous resin coating layer 5 will be described. 100 parts by weight of ethylene acetate vinyl emulsion (trade name "Sumikaflex-401", manufactured by Sumitomo Chemical Co., Ltd.) and 100 parts aluminum hydroxide (trade name, "Hijilite H-42", manufactured by Showa Denko KK) 2 parts by weight of a dispersant (trade name "Smilet's Resin DS-10", manufactured by Sumitomo Chemical Co., Ltd.) is added, and further a foaming agent (trade name "F-85", Matsumoto Yushi Kagaku Kogyo Co., Ltd.) is added. (Manufactured by Co., Ltd.) 15 parts by weight, a water retention agent, an antifungal agent, a flame retardant, and a colorant are added in total of 3 parts by weight to prepare an aqueous synthetic resin coating solution having a concentration of 60 to 70% by weight and a viscosity of 7,000 to 10,000 cps. adjust.

Next, the coating liquid is applied to the surface of the base paper by using a roll bar coater, a comma coater or the like, and dried at a foaming temperature or lower to obtain the cosmetic material of the present invention. Be done.

The cosmetic material of the present invention is manufactured by the method as described above. Next, an example of manufacturing a decorative material using this material will be described. If the unfoamed water-based resin coating layer 5 has a high coating amount, after printing a pattern, a pattern or the like on the surface of the unfoamed water-based resin coating layer layer 5 with an offset or gravure printing machine, 120- After heat treatment at 170 ° C. for 20 to 30 seconds to foam, embossing is performed to obtain a cosmetic material. When the unfoamed water-based resin coating layer 5 has a low coating amount, after similarly printing a pattern, a pattern, etc., the unfoamed water-based resin layer as described above is further printed using a gravure or rotary screen printing machine. If necessary, a colorant is added to the coating liquid for the resin coating layer to perform partial printing, and foaming and embossing are performed to obtain a decorative material. This method is suitable for obtaining a decorative material with a sense of gradation. If it is desired to further improve the surface strength of the decorative material, various resins may be further surface-coated before or after the foaming step.
