An object of the present invention is to provide a simple coating method for covering the surface of the wooden board used for furniture F.R.P. Furniture is mainly made of wooden boards, and surface treatments are various, such as cloth, hoimaka lacquer, lacquer, etc., and these are finished through the process of sub-layer and middle layer in consideration of solidity and design, so that each floor is hand-made or individually. After polishing and painting several times, it takes a long time to complete the workmanship as well as the completion of manufacturing. However, the durability is poor, and there is a defect that the temperature difference due to climate change, the grain of wood or cracks due to a slight impact are easily generated.

In view of the above problems and shortcomings, the present invention covers furniture plates (particularly furniture doors or desk boards) to the surface as well as to the edge of FRP low body, which is durable and stable in strength and heat resistance and moisture resistance. In order to apply FRP to the surface of wooden boards, such as to provide a material or to make a note, it is not feasible to use the surface coating liquid treatment that the surface is smoothly polished by the usual method. First, a mold having a concave surface coincides with the outer surface of the material to be made. First, a mold release agent is applied to the concave surface of the mold, and the surface is coated with a hard resin solution and cured. The FRP resin liquid is evenly spread through the gap between the indentation surface and the plate surface by placing and pressurizing the plate. Since the FRP layer was evenly coated on the surface of the plate, the material expected in the present invention was obtained. The surface coating resin liquid and the FRP resin liquid used in the present invention are so-called superfine fibers that combine a fibrous reinforcement with a resin, as is well known. As a thermosetting resin, unsaturated polyester resin, epoxy resin, phenol resin, melamine resin, etc., which is relatively pointed, cured at room temperature and atmospheric pressure, and has high adhesion to glass fiber, is used. Molding is made of a high strength resin, and various release agents include waxes, restin, silicone resins or polystyrene glycols.

In addition, various pigments may be added to the surface coating resin liquid or the dough-like F.R.P resin liquid to adjust the color thereof arbitrarily.

The F.R.P resin liquid used in the present invention is prepared by mixing 10 to 30 parts by weight of the ceramic fiber 100 to 200 parts by weight and 0.5 to 3 parts by weight of the reinforcing agent based on 100 parts by weight of the curable resin.

The vitreous fibers may be 10 _mm- 15 _mm long, but in the case where the FRP resin liquid becomes a surface, it is preferable to use 0.5 _mm or less in order to improve the surface state of the coating layer. The amount of vitreous fiber may also be used in an amount of 10 to 30 parts by weight based on 100 parts by weight of the resin, but it is preferable to use 15 parts by weight or less to give surface smoothness. The solvent uses a volatile solvent, and the solubility of the above-mentioned thermosetting resin is good, and it is preferable to volatilize rapidly at room temperature after coating.

That is, an aromatic resin, an alcohol, a ketone solvent, and an ester polyester and a ketone solvent are preferable for an epoxy resin.

As the reinforcing agent, acid anhydride-based and amine-based curing agents are used for epoxy resins and methyl ethyl ketone peroxide is used for unsaturated polyester resins.

The F.R.P resin solution thus prepared may be arbitrarily selected in the range of 50 to 1,000 g / m 2 depending on the required coating thickness.

Referring to the present invention as described in detail based on the accompanying drawings as follows.

In FIG. 1, (1) is a processed wooden board which is a door of furniture, and (2) is prepared in advance as a mold in which the recessed surface 2a is molded so that the surface of the board 1 can be matched.

FIG. 2 is an embodiment of the present invention. In FIG. 2 (a), the release agent 3 is applied to the recessed surface 2a of the mold 1, and the surface coating resin solution 5 is applied to the inner surface of the dough. The FRP resin liquid 4 is interposed with the proper orientation necessary for the thickness, and in FIG. 2 (b), the plated material 1 is processed to have a surface coincided with the recessed surface 2a interposed in the FRP resin liquid 4 and pressurized. FRP resin liquid is spread evenly between the recessed surface and the plate surface to cover the plate surface, and when hardened, the plate is detached from the mold to obtain a material having the surface of the FRP layered.

The plate obtained in this way is made of FRP with high strength and excellent heat resistance and moisture resistance. Therefore, it is suitable as a furniture material that does not cause cracks in temperature differences or external shocks caused by climate change. Breaking the notion that it is not feasible, since it can be very simply laid, it has the advantage of less manpower consumption and mass production in a short time as compared to the method of manually polishing the surface of furniture plate by hand in several layers as in the prior art.
