Field of the Invention The present invention relates to a decorative board, and more particularly to an antifouling decorative board whose surface is easily decomposed by light. 2. Description of the Related Art Conventionally, there is a decorative plate provided on a horizontal surface such as a table, a counter, and a kitchen, and a vertical surface such as a wall and a booth, and is excellent in various physical properties such as abrasion resistance and impact resistance. Thermosetting resin decorative boards such as diallyl phthalate resin decorative boards and melamine resin decorative boards are widely used. [0003] However, various contaminants adhere to the surface of the decorative plate in daily life and cannot be easily removed if left unattended. In particular, if the decorative surface is embossed, it must be rubbed with a cloth or the like with force. Even if the surface is flat, the surface may not be covered by the ultra-fine surface of a metal plate or plastic film. Since the transfer was performed, the dirt could not be easily and easily removed. [0004] The present invention has been studied in view of such circumstances, and is characterized by the following. That is, a base material, a resin-impregnated decorative paper, and a surface paper for a decorative board are sequentially laminated with a silicone resin-impregnated surface paper impregnated with a silicone-based binder, hot-pressed, and then coated with a photocatalytic coating agent. It is an antifouling decorative board characterized by the following. [0005] As shown in the present invention, a primer layer is formed by incorporating a silicone-based binder into a surface paper for decorative board, and a photocatalytic coating agent is applied after hot pressing to form a decorative surface. A photocatalyst layer can be formed on the substrate. Hereinafter, the present invention will be described in detail.

Examples of the basic catalyst include oxidation of alkali metals such as sodium and potassium and alkaline earth metals such as magnesium and calcium. And hydroxides, and amines such as triethylamine and triethanolamine. [0009] The resin impregnated decorative paper has a basis weight of 20 to 200 g.
/ M 2 , which is obtained by impregnating resin paper made of thermosetting resin into decorative paper on which various patterns are applied by coloring or printing. Examples of thermosetting resin include diallyl phthalate resin, unsaturated polyester resin, Examples thereof include amino-formaldehyde resins and mixtures thereof. In particular, amino-formaldehyde resins are preferable in terms of surface properties such as heat resistance and water resistance.
Preferably, a formaldehyde resin is used. Examples of the amino-formaldehyde resin include an initial condensate obtained by reacting an amino compound such as melamine, urea, benzoguanamine and acetoguanamine with formaldehyde, and etherification with a lower alcohol such as methyl alcohol and ethyl alcohol. And those modified with a reactive modifier which promotes plasticization, such as paratoluenesulfonamide. The silicone binder used in the present invention strengthens the adhesion to the photocatalyst coating agent described below and fixes the photocatalyst. The silicone binder is not affected by the decomposition function by the photocatalysis. Or a polysiloxane or a silicone-modified resin resistant to a decomposition function. ## STR1 ## (Where n represents an integer of 0, 1, 2, 3;

When n is 1, trifunctional silanes such as methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, and propyltriethoxysilane are exemplified. When n is 2, bifunctional silanes such as dimethyldimethoxysilane, dimethyldiethoxysilane, diphenyldimethoxysilane, and diphenyldiethoxysilane are exemplified. When n is 3, monofunctional silanes such as trimethylmethoxysilane, trimethylethoxysilane, trimethylisopropoxysilane, and dimethylisobutylmethoxysilane are exemplified. Examples of the polysiloxane include a hydrolyzable silicone compound monomer such as the above-mentioned alkoxysilane, a polymer obtained from a partial hydrolysis product thereof, and colloidal silica. The silicone-modified resin is obtained by introducing silicone into a synthetic resin. Examples of the synthetic resin include synthetic resins such as acrylic resin, epoxy resin, alkyd resin, urethane resin, and polyester resin. Among the synthetic resins into which silicone has been introduced, acrylic silicone resins and epoxy silicone resins are excellent in film formability, film strength, and adhesion to carriers. The silicone resin impregnated surface paper has a basis weight of 16
4040 g / m 2 surface paper for decorative board is impregnated with the aforementioned silicone binder. The photocatalyst coating agent applied to the surface is composed of a photocatalyst, the above-mentioned silicone-based binder, and a photocatalyst active catalyst used as required. The photocatalyst reacts when irradiated with light of a specific wavelength.

Among these oxides, they are high in sunlight and illumination light used in daily life. Titanium oxide having catalytic activity is particularly desirable. As the titanium oxide, rutile type titanium oxide,
Examples include anatase-type titanium oxide and flukite-type titanium oxide. Anatase-type titanium oxide is more readily available, is inexpensive, has stable properties, is harmless to the human body, and exhibits excellent effects as a photocatalyst. . Further, the photocatalytic activity of metals and metal oxides such as platinum, ruthenium, silver, ruthenium oxide, niobium, copper, tin and nickel oxide is promoted within a range that does not hinder the pattern and color tone of the surface of the thermosetting resin decorative board. An agent may be attached or coated on the surface of titanium oxide. The silicone binder used at the time of impregnation and the silicone binder contained in the photocatalyst coating agent for surface application may have the same composition or different compositions, and may be a primer layer for fixing the photocatalyst to the surface. It is desirable to use a polysiloxane in combination with the silicone binder in the photocatalyst coating agent applied to the surface in order to ensure good hardness and smoothness. In the photocatalyst coating agent, a titanium-based coupling agent, a titanium-based coupling agent,
A silane coupling agent may be included. The method for applying the photocatalyst coating composition is not particularly limited, and includes spray coating, flow coating, and the like.
