We hope to contribute to the development of this industry by providing a manufacturing method that can be easily attached and also easily converting wood veneer itself into WPC.
以下本発明の化粧板の製法について第１園及び第２図の
実施例に基いて詳細に説明する。The method for manufacturing a decorative board of the present invention will be explained in detail below based on the embodiments shown in Fig. 1 and Fig. 2.

A foaming agent is mixed into a synthetic resin such as 51% hard urethane resin, polyethylene resin, or polyethylene resin, and the mixture is heated and expanded to a size of 1.0 to 4 times to form a foam. It is preferable to rapidly cool only the surface part of the granite stock to make one surface part as non-foaming as possible.
5c is used.

When applying urethane resin of 1t70ro001, 1 wood veneer (covered with powder, heated to increase the amount of foaming of the urethane resin, and part of the urethane resin was soaked in the inner mold of the wood veneer (2). Then, the wooden veneer (2) and the base material (1) are bonded together using the urethane foam layer (3) to obtain a decorative board (4).

When foaming the urethane resin, keep only the surface of the foam that forms the base material (1) as unfoamed as possible. - At the same time, the surface of the helmet foam is re-foamed, pushing the essential veneer (2) up against the inner wall of the sizing (5) from below, and improving the adhesive strength between the urethane foam layer (3) and the base material (1). It is for this purpose.

ある。In addition, the wood veneer (2) used in the present invention is preferably a t-th veneer of a coniferous tree, and is soaked in advance at 60°C in a hydrogen peroxide aqueous solution (containing a stabilizer) at a concentration of 3. temperature for about 150 minutes to 210 minutes, then reduce the moisture content to u
% to tm%. This is to prevent the urethane resin from being able to foam sufficiently in the mounds where it is foamed, as it is easily hardened by water.Then, the wood veneer (2) is rolled. Press (6) (
6) It is possible to loosen the buckled wood fibers through the
Delicious. The best way to loosen wood fibers is to use a metal brush! It is also good to polish one stroke; this is a necessary step to make it easier for the urethane resin to penetrate inside the wood veneer (2).

ことか出来゛る。In the present invention, the base material (1) in which wood veneer (glue) is laminated via urethane resin is introduced into the sizing II (!l), and the urethane wood is placed in the sizing M(5) by "1!l?" If the surface layer of the base material (1) is foamed, the wood veneer (2) will be pressed to 3#c within the sizing m1 (5) due to its internal pressure, and the urethane will be added to the inside of the wood veneer (2). The resin penetrates and the wood veneer (2) can be reliably converted to WF6.
