In addition, in the latter method, when washing away the WPC resin with acetone, it is necessary to insert a spacer for each veneer so that the acetone can sufficiently act on the veneer, which requires the complicated work of setting the spacers. This created a problem in terms of production efficiency. The present invention has been made in view of the above points, and it is an object of the present invention to provide a method for manufacturing a WPC veneer that allows coloring to bring out the wood grain without causing problems in production cost or production efficiency. It is something.

用板を得ることができる。The method for manufacturing a WPC veneer according to the present invention is characterized by applying a coloring agent to the surface of the veneer, drying it, and then subjecting the veneer to WPC treatment. The present invention will be explained in detail below. The veneer 1 is obtained by slicing a piece of wood, and the preferred wood species is oak, which has a conduit portion.In the present invention, first, a liquid coloring agent is applied to the wood grains on the surface of the veneer 1. The colorant 2 to be applied with the colorant 2 is a pigment that does not dissolve in the WPC resin, and it is preferable to use the colorant 2 prepared by mixing the pigment with the resin. After curing, it is WP
The coloring agent 2, which is preferably an acrylic emulsion resin that does not dissolve in the C resin, can be applied by passing the veneer 1 through a roll coater 3 formed by a sponge roll, as shown in FIG. When the colorant 2 is applied to the surface of the veneer 1 in this way, the colorant 2 penetrates into the conduit, but the conduit is formed with a large diameter at the spring wood part (conduit part) of the wood grain. Since the diameter of the autumn wood part of the wood grain is very small, the coloring agent 2 can fully penetrate into the conduit part and color the conduit part, making it possible to bring out the grain of the wood. After the coloring agent 2 is applied to the veneer 1 in this manner, the resin of the coloring agent 2 is cured or solidified by curing and drying. Next, the 21st! As shown in I, this veneer 1 is placed in a processing tank 4 such as a pressure regulating tank, the pressure is first reduced, then the pressure is increased, and the WPC treatment is performed by injecting the WPc resin into the veneer 1.The WPC resin contains pigments. A clear unsaturated polyester resin that does not contain is used. After the WPc resin is semi-cured, the veneer 1 is placed on the surface of a base material such as plywood using an adhesive, and the WPC resin is completely cured by applying heat and pressure, and the veneer 1 is bonded to the base material. Furthermore, by polishing the surface of the veneer 1 to remove the coloring agent 2 adhering to the surface, the wood grain is brought out so that the difference in the degree of coloring between the conduit part and other parts becomes clear. It is possible to obtain architectural boards used as flooring materials and the like.

There is no need to use a spacer, which is required when coloring the C resin after washing it off from the veneer with acetone or the like, and the production efficiency does not deteriorate. Also, add 2 parts of the colorant to 1 part of the veneer.
For coating, existing equipment such as the roll coater 3 can be used as is, and equipment investment will not be a problem.

しをおこなった。Next, the present invention will be specifically explained with reference to Examples. Colorant 2 was prepared by using a 1.0 mm thick oak veneer 1 and containing 70 parts by weight of water, 30 parts by weight of acrylic emulsion, and 5 parts by weight of pigment. was applied onto the surface of the veneer 1 using a sponge roll coater 3 in an amount of 80 to 120 g/m2, and was cured for 12 hours and dried until the moisture content became 6% or less. Next, this veneer 1 is placed in a treatment tank 4, and the pressure is reduced to 10 torr or less for 1 hour, and then the pressure is increased to 18 kg/cm2 for 1 hour to perform WPC treatment in which unsaturated polyester resin is injected into the veneer 1. The veneer was heated at 90° C. for 15 minutes to semi-cure the unsaturated polyester resin. After this, apply one layer of water-based vinyl urethane adhesive to the surface of the plywood.
The unsaturated polyester resin is cured and the plywood is formed by applying the resin at a coating weight of 00 to 120 g/m2, overlaying the veneer 1 on top, and heating and pressurizing it for 3 minutes at 130°C and 8 kg/cm2. Veneer 1 was adhered to. Finally, the surface of the veneer 1 was sanded with #180 sand and then sanded and polished with #240 sand to bring out the grain of the veneer 1.

くなるものである。As mentioned above, in the present invention, a coloring agent is applied to the surface of the veneer and dried, and then the veneer is treated with WPC, so that a WPC veneer with coloring to bring out the wood grain can be manufactured. In doing so, coloring can be done by applying a coloring agent to the veneer, which eliminates the need to prepare a large number of WPC resins and tanks, unlike when using a mixture of colorants with WPC resin. This eliminates the need to increase production costs, eliminates the need to use spacers as in the case of washing the WPC resin from a veneer with acetone, etc., and then coloring it, thereby eliminating deterioration in production efficiency.
