The present invention relates to a method for producing hard wood having uniform strength to the outer and inner layers of the entire wood layer in producing hard wood as artificial wood.

Since various types of artificial wood are artificial wood for decorative purposes, a manufacturing process is performed to enhance the gloss and enhance the outer layer, that is, the surface or the back surface, rather than the equivalent hard structure of the outer layer and the inner layer. Therefore, in the conventional artificial wood, it was not possible to obtain a hard artificial wood having an equal strength to be used as a variety of machine parts that are the object of the present invention. Since it was manufactured by the method, the compression and resin infiltration of the inner and outer layers of the timber were uneven, so the quality of the hard wood for making various mechanical parts was very poor in quality. Therefore, the present invention avoided such a conventional method as artificial wood. The entire outer and inner layers have a uniform strength and are made of hard wood with high electrical insulation, and can be used to manufacture various mechanical parts. same.

The raw wood is cut into a raw material thin plate (1) of about 0.5-1.5 mm to achieve a humidity of 0-3 so that several raw material thin plates (1) are inserted into each one between the compartmental partitions (3) of the vacuum chamber (2) and opened and closed. The valves 7 and 9 are closed and the opening / closing valve 5 is opened, and the pressure reduction by the operation of the vacuum pump 4 is performed for about 50 minutes to equalize the fibrous air bubbles and foreign objects of the raw material sheet 1. After extraction, the on / off valves (5) and (9) close and open the on / off valve (7) and are sucked into the phenol resin chamber (2) while infiltrating into the raw material sheet (1). Closing the valves (5) and (7) and opening / closing the valve (9) to pressurize the air for about 60 minutes with pressurized air (approximately 7 kg / cm2) of the pressurized air tank (8). To improve the electrical insulation by extracting and then sufficiently infiltrate the phenolic resin into the raw material thin film (1) to the fibrous layer of the raw material thin plate. The phenol resin impregnation was made to be uniform in the entire layer to improve the hardness and electrical insulation of the finished product.

Next, the raw material sheet 1 is inserted one by one between the standing partition grids 12 placed on the mesh frame 11 in the drying chamber 10 and blowers are blown into the drying heater 13 below the mesh frame 11. Pass the wind of (14) and raise the drying hot air through the mesh frame 11 to maintain the temperature in the drying chamber 10 at 90 ° C-100 ° C for about 4 hours to completely volatilize the alcohol component of the phenol resin. After the drying is carried out, the raw material thin plate 1 is superimposed on the upper surface of the pressure plate 16 by a reasonable number of products, and the press plate 16 is pressurized by the pressing operation of the press pressure section 26 of the press 25 at the bottom of the press. In addition, opening / closing valves 22 and 20 'are opened and closed valves 20 and 22' are opened, and the heating temperature of heating plate 16 is set to 150 ° C-190 ° C by steam of steam pipe 19. It is carried out for about 60 minutes so that the phenolic resin layer and the fibrous layer of each raw material thin plate 1 are composed of a single unit. In order to discharge the fresh gas, press pressurizing section 26 is lowered, and after 10 minutes, 200 kg / cm 2 pressurization is again performed for 40 minutes, and the steam circuits of the open / close valves 20 and 22 'are closed and the open / close valve 22 is closed. The cooling water circuit of (20 ') is opened, and the cooling water of the cooling water tank 21 is piped (17). When the temperature of the pressure plate 16 is lowered to 50 ° C. or lower, and the raw material thin plate 1 is piled up, the raw material thin plate 1 is overlapped one by one, and one group is overlapped between the pressure plate 16 to overlap the thin plate 1 of several sheets. During the production of plate wood, a plurality of plate materials are press-bonded between the platen plates 16 by interposing a thin plate-separated nonferrous metal plate 24 such as a stainless plate between sets.

After separating the present invention one by one, the phenolic resin was impregnated in the raw material thin plate (1) vacuum-reduced and pressurized to completely volatilize the alcohol components, and discharged the generated gas during the raw material thin plate (1) overlapping pressurization and then pressurized to cool the wood. It has the compressive strength of resin completely infiltrated with sulphyl cell pores, so it has high electric heat resistance and can be used as a variety of electric household parts such as transformers. In addition, it is to obtain a hard wood that has the advantage that the gloss does not change even if the surface is worn.
