DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface decorative material for building materials such as wall surfaces and furniture, and when the building material is reformed, leaves a smooth peeling surface and easily peels off the surface decorative material.
The present invention relates to a cosmetic material that can easily use a cosmetic material for renovation.

[0002]

2. Description of the Related Art Hitherto, constructions relating to surface decorative materials for building materials such as various wall surfaces and furniture have been developed. For example, it has been processed after providing a decorative layer on a plastic film, applying an adhesive or a sticky material, and attaching it to a plywood or wall material. In addition, in the case where the decorative sheet is provided on the constructed wall surface, a paper or plastic film provided with a pattern layer and a moisture absorbing paper surface of the decorative sheet and the laminated surface of the decorative sheet are provided with an emulsion-based adhesive layer using water as a medium. Had been worn and constructed.

[0003] When these decorative surfaces are peeled off for reforming, if the decorative material and its adhesive strength are stronger than the surface strength of the wall surface, the wall surface may be peeled or damaged to form irregularities. It was necessary to repair the surface of the wall to make it smooth. Conversely, if the strength of the surface to which the decorative material is adhered is inferior, the material may break down between layers or the adhesive layer may remain. It was necessary to remove the agent layer.

[0004] In the case of a conventional cosmetic material, information such as material, use method, and disposal method is described in a sample notebook, an outer box, and the like before construction. However, the applied cosmetic materials rarely remain so that the information can be read. Therefore, there has been a resource loss that landfill disposal is performed even for resources that cannot be accurately disposed because the material of the removed and removed cosmetic material and the disposal method are unclear, and that can be reused.

[0005]

As described above, the conventional decorative material is peeled off because the surface to be peeled is damaged when the decorative material is forcibly peeled off due to reforming, or the decorative material or the adhesive layer remains. There is a problem that unevenness on the surface must be repaired smoothly. Another object of the present invention is to provide a cosmetic material that can be properly disposed by leaving the material and the disposal method of the cosmetic material removed and removed clearly, and a method of using the same.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. The release layer of the present invention is provided for the purpose of closely adhering a surface substrate on which a picture layer is provided and a rear substrate adhered to a wall surface or the like (this means that the substrate adheres temporarily but can be peeled off if necessary). It is. Then, a decorative material for remodeling with the formed multilayer base material is provided on a wall or the like, and when only the surface material of the decorative material is peeled off at the time of reforming, a pattern layer is easily provided by separating and peeling between the peeling layers. Only the surface substrate that has been removed can be removed.

The release layer of the present invention uses a conventionally known re-peelable pressure-sensitive adhesive. That is, as the non-peelable pressure-sensitive adhesive such as various rubbers, an acrylic-modified natural rubber obtained by graft-polymerizing methyl methacrylate onto natural rubber, which is a rubber latex, is used. Modification with polymethyl methacrylate takes advantage of the strong self-adhesiveness of natural rubber,
This is for improving the adhesion to the substrate, which is a drawback. And, in order to give the adhesive strength that can be re-peeled, the blocking resistance, fillers such as silica, starch, methyl cellulose, ethyl cellulose, calcium carbonate, magnesium carbonate, zinc oxide, titanium oxide, kaolin, clay, talc, alumina, etc. Add. The filler is preferably a hydrophilic filler that does not impair the suitability for the emulsion paste used for sticking the reformable cosmetic material on the release surface again, such as starch, methylcellulose, and emethylcellulose.

The release layer uses styrene / butadiene rubber latex, acrylonitrile / butadiene rubber latex, or acrylic resin latex instead of natural rubber latex in order to stabilize the release surface when re-peeling is smooth. You can also. The filler to be added to these latexes is 5 to 70 parts by weight based on 100 parts by weight of rubber latex (hereinafter referred to as a solid content ratio) in the case of fine particles such as silica. If the particle size is relatively large, it is 5 to 50 parts by weight.

Since the release layer is usually supplied in the form of a latex, the coating liquid containing the above-mentioned filler and the like can be used by a conventional coating method such as a gravure coat, a roll coat, and an air knife coat. . In addition, when the backing substrate is a porous paper having a small size, a fibrous derivative, a resin latex or a resin varnish is applied as a seal to prevent paper peeling (paper delamination) when peeling. can do. In addition, if the surface properties of the synthetic paper or plastic film can be obtained by stably adhering to rubber latex, if a plastic film is mainly used, the amount of release agent provided on the surface substrate Is set to the minimum amount of 0.1 to 0.5 g / m ² including 0, and sufficient adhesion can be obtained by coating the required amount of ² to 5 g / m ² on the back substrate mainly composed of paper. Further, when printing and forming information such as a description on the back surface of the front substrate (the surface in contact with the back substrate), it is preferable to apply a latex amount exceeding the thickness of the printing ink and covering the printing ink. .

The backing substrate used in the present invention is a substrate which is a substrate of a decorative material and is preferably a material which can adhere to a wall surface or a plywood via an adhesive layer. The adhesive to be applied at this time is often aqueous, such as an emulsion or latex, and it is preferable to impart hydrophilicity to paper made of water-absorbing cellulose, or to a non-absorbing surface by corona surface or primer treatment.

Preferred backing substrates include kraft paper, woodfree paper, tissue paper, synthetic paper, plastic films and the like. Also, plastic film on the first back substrate,
When synthetic paper is used, if the back substrate used for reforming is made of paper, it can be bonded with an aqueous adhesive. The first backing substrate prevents the penetration of moisture from the wall into the wallpaper and decorative paper used for the reform, prevents the deterioration of the paper and the expansion and contraction of the paper due to moisture absorption and desorption, and peels off the reformed multilayer substrate by curling It has the effect of preventing.

As the surface substrate, any paper or plastic film can be used as long as it is a material to be printed on a decorative material. In addition, a picture layer may be provided on paper or a plastic film, and further a protective layer formed by coating a plastic film or a thermoplastic resin or a reaction-curable resin.
