Abstract

PROBLEM TO BE SOLVED: To enhance water resistance, heat resistance, antifouling properties and damage resistance by arranging thermosetting resin impregnated papers to both upper and rear surfaces of a substrate to heat and press the same to form resin impregnated paper layers and applying a transparent ultraviolet curable paint to the resin impregnated paper layer on the upper surface side to irradiate the same with ultraviolet rays to form an ultraviolet cured paint layer. SOLUTION: Thermosetting resin impregnated paper 3 on a rear surface side, a substrate 1 and thermosetting resin impregnated paper 2 are laminated in this order from below between the hot plates of a hot press apparatus and integrally bonded under heating and pressure to cure the thermosetting resin in the impregnated papers to obtain a decorative panel intermediate object 4. Heating and pressurization are performed at 120-140 deg.C under a pressure of 8-20 kg/cm2. Subsequently, a transparent ultraviolet curable paint comprising an unsaturated polyester resin is applied to the surface of the intermediate object by a flow coater to form an ultraviolet curable paint layer 5. The total coating amt. thereof is set to about 50-100 g/m2 in terms of a solid. The wt. of the thermosetting resin impregnated papers 2, 3 is pref. 100-200 g/m2 and the thickness thereof is pref. about 0.15-0.30 mm.

2. Description of the Related Art Conventionally, a thermosetting resin-impregnated paper obtained by impregnating a printing paper with a thermosetting resin liquid and drying it in a so-called B-stage state has been used as a wall material around the kitchen or water. It is well known that a decorative plate is formed by disposing a thermosetting resin-impregnated paper on the above-mentioned substrate integrally with the substrate by applying heat and pressure to the surface of a substrate such as a calcium silicate plate.

[0003] Since the surface of such a decorative board is protected by a thermosetting resin-impregnated paper, it has excellent physical properties such as water resistance, heat resistance, abrasion resistance and hardness. It is used in areas that are easily affected by water, heat, scratches, etc.

However, since the decorative board has fine irregularities on its surface, it is relatively easy to adhere to dirt, and when a printed pattern is provided on a resin-impregnated paper, the sharpness of the printed pattern is reduced. It has the drawback of lowering the decorative appearance by lowering the surface and making the surface smoother worse, especially when a lightweight inorganic plate is used for the substrate, the influence of the surface of the rough inorganic plate is reduced. In addition, there is a problem that it is easy to appear on the surface of the decorative plate.

On the other hand, a polyethylene terephthalate resin (PET resin) film is placed on a thermosetting resin-impregnated paper so as to make it difficult to adhere to the surface and integrated by heat and pressure. Although a layer is also provided, since polyethylene terephthalate resin has poor adhesiveness, a primer treatment is performed between the thermosetting resin-impregnated paper and the film, or a corona discharge treatment is performed on the back surface of the film. In addition, it is necessary to improve the adhesiveness between the two, and it takes time and effort. In addition, such a thin film has a disadvantage that it cannot absorb the influence of the fine irregularities of the thermosetting resin-impregnated paper.

According to the first aspect of the present invention, the thermosetting resin-impregnated layer is formed on both the front and back surfaces of the substrate, and the ultraviolet-curable paint layer is formed on the impregnated layer. Such irregularities can be covered with the UV-curable paint layer to form a mirror-like surface appearance, and it is possible to obtain a smooth and beautiful decorative board which is hardly stained or scratched. Further, even when a printed pattern or the like is formed on the resin-impregnated paper, the printed pattern can clearly appear on the surface of the decorative board.
