Abstract

PROBLEM TO BE SOLVED: To enable aqueous wax to be applied smoothly during maintenance services by structuring a decorative material of a slip agent with such a nature as to adsorb moisture, added to the top face of a decorative material of a filmlike, a sheetlike or a platelike shape. SOLUTION: This decorative material is of such a constitution that a slip agent with such a nature as to adsorb moisture is added to the top face of a decorative material of a filmlike, a sheetlike or a platelike shape. The slip agent with such a nature as to adsorb moisture to be used is a polyether- modified silicone oil which has a dimethylsiloxane skeleton in which one methyl group is present or has polyether such as polyethyoxide or polypropylene oxide introduced into both terminals. Thus it is possible to prevent an aqueous wax from being repelled when the aqueous wax is applied and also prevent partial smears from being promoted or partial scratches from being easily inflicted because the aqueous wax is not applied, by using the slip agent.

2. Description of the Related Art Conventionally, various kinds of decorative materials have been developed and used according to their applications. For these decorative materials,
In order to maintain the appearance and performance at the time when the decorative material was applied, for example, work for wiping off dirt that has adhered and maintenance work for repairing scratches are generally performed. Is used for cleaning and preventing stains. In particular, in a decorative material used for floors, wax prevents adhesion of substances that cause dirt, and also prevents the lining of shoes from being rubbed against the floor with a strong force. It is said that carbon and rubber mixed in the lining of shoes prevent the floor surface from being rubbed with scratches.

Originally, in the category of cosmetic materials, there are those in which a slip material such as silicone acrylate or fluorine acrylate is applied to the outermost surface of the cosmetic material in advance, but a cosmetic material obtained by using these types of slip agents is used. In the material, the drawback that the coating agent is repelled when the water-based wax is applied cannot be eliminated, and conversely, even if it is made without adding silicone or fluororesin, it is slightly improved, The application was quite difficult. It is considered that this is because this type of decorative material is generally made of a resin having water resistance or water repellency.

[0004]

Therefore, the problem to be solved by the present invention is to provide a novel decorative material having a surface on which an aqueous wax can be smoothly applied during maintenance.

[0005]

In order to solve the above object, the decorative material of the present invention comprises a slip agent having a property of adsorbing moisture on the outermost surface of a film-shaped, sheet-shaped or plate-shaped decorative material. It has the composition to contain.

BEST MODE FOR CARRYING OUT THE INVENTION The decorative material of the present invention can have various structures as long as it can contain a slip agent having a property of adsorbing moisture on the outermost surface. For example, it can be applied to a vinyl chloride resin tile composed of a vinyl chloride resin and a large amount of an inorganic filler, or a vinyl chloride resin tile whose surface is printed or embossed. A vinyl chloride resin tile usually has a size of about 30 cm square, but it may have a wider sheet and a longer sheet shape, or a so-called cushion using a vinyl chloride resin foam sheet. It may be the floor. In these cases, a slip agent having a property of adsorbing water is applied by kneading the whole sheet. Alternatively, when coating the surface for the purpose of strengthening these surfaces, it may be applied by being mixed with the coating material used for coating.

When a transparent film, sheet, or plate made of resin is used, printing is performed on the back side, and subsequently, a concealing layer is further provided if necessary, and printing, embossing, painting on the front side. Etc. can also be applied arbitrarily. In the case of this transparent type decorative material, a slip agent having a property of adsorbing moisture is kneaded into a film, sheet or plate made of a transparent resin, or is mixed with a paint used for surface coating and applied.

The decorative material of the present invention may not only be mainly composed of synthetic resin, but may be based on paper.
A typical example is thin paper or impregnated paper, on which a pattern is printed, and then the surface is painted. In this case, a slip agent having a property of adsorbing water is mixed with the paint used for coating or impregnation and applied. In addition, various kinds of materials such as various papers other than these, a plastic film or a plastic sheet, a metal foil, a metal sheet, a metal plate, a wood-based plate, or a single plate obtained by thinly slicing a plate, alone or in combination. It may be based on the body. In these cases, if there is a plastic film or plastic sheet on the outermost surface, knead a slip agent that has the property of adsorbing moisture in that part, or use it when painting the outermost layer. It is good to apply it by kneading it with the paint.

These plastic films, plastic sheets, or plastic plates may be subjected to corona treatment, primer coating, etc., if necessary, for the purpose of improving the adhesive strength with adhesives, inks, paints and the like.

Another method of applying a slip agent having a property of adsorbing water is a method in which, when the outermost surface layer is formed by coating, it is formed by kneading and coating with the coating material. Regarding the synthetic resin which is the main component of the coating material, it can be selected according to the application, vinyl chloride-vinyl acetate copolymer, saturated polyester resin, or thermoplastic resin such as acrylic resin, aminoalkyd resin, polyurethane resin,
Alternatively, a thermosetting resin such as an epoxy resin can be used.

As the main component of the paint, in addition to the above, an ionizing radiation curable resin can be used. Specifically, a polymerizable unsaturated bond or an epoxy group-containing prepolymer, oligomer, and / or monomer are appropriately mixed in the molecule,
The composition is an ionizing radiation curable composition. The ionizing radiation refers to an electromagnetic wave or a charged particle beam having an energy quantum capable of polymerizing or crosslinking a molecule, and usually, an ultraviolet ray or an electron beam is used.

In order to provide suitability, it is preferable that the prepolymer or oligomer is 5% by weight or more and the monomer and / or polythiol compound is 95% by weight or less.

When flexibility is required when the ionizing radiation-curable resin composition is applied and cured, the amount of the monomer may be reduced or an acrylate monomer having 1 or 2 functional groups may be used. . When abrasion resistance, heat resistance, and solvent resistance when an ionizing radiation curable resin composition is applied and cured are required, use an acrylate monomer having three or more functional groups, such as ionizing radiation.
