待てきない。In order to modify wood, WPC treatment, which involves infiltrating unsaturated polyester resin into wood and curing it, has traditionally been carried out. Generally, when the unsaturated polyester used in this WPC treatment comes into contact with air, the reaction is inhibited by the influence of oxygen in the air, making it difficult to completely cure it. For this purpose, wax or the like is added to the unsaturated polyester resin, and a wax film is formed on the surface of the unsaturated polyester resin to block air, thereby sufficiently curing the unsaturated polyester resin. There is. However, when curing the unsaturated polyester resin, a high temperature of 60° C. or more must be applied, or the wax may be evaporated at this time, so that the effects of wax are not expected to be very effective.

処理方法を提供することを目的とするものである。Therefore, even if the unsaturated polyester resin infiltrated into the wood is cured, the unsaturated polyester resin or an uncured layer that is not completely cured will remain on the surface, which may clog the sander when sanding the surface. This was the reason why it became easier. 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 treating wood by which unsaturated polyester resin can be cured without leaving an uncured layer on the surface thereof. This is the purpose.

ダーの目かつまる等の問題かな（なるものである。The method for treating wood according to the present invention is characterized by impregnating the wood H with an unsaturated polyester resin, then impregnating the surface of the wood with a condensing agent, and then heating to cure the unsaturated volustelle resin. It is. The present invention will be explained in detail below. As for the unsaturated polyester resin, use one that is generally used as a WPC impregnation liquid, for example, an unsaturated polyester resin with a curing agent such as peroxide or other substances such as styrene added as necessary. I can do it. Then, the unsaturated polyester resin can be impregnated into the wood by immersing the wood in this unsaturated polyester resin and subjecting it to a treatment such as reduced pressure. Further, as the condensing agent, a metal chelating agent or the like can be used. A curing accelerator such as cobalt stearate may also be used. The condensing agent is used dissolved or dispersed in a solvent, and wood impregnated with unsaturated polynisder resin is immersed in a solution of the condensing agent, or a solution of the condensing liquid is applied to the wood. It is possible to infiltrate the surface of the wood with a condensing agent. 1) As described in 2 (7), after infiltrating the unsaturated polyester resin into the wood and impregnating the condensing agent into the surface of the wood, heating it to a high temperature of about 90 to 180°C. The unsaturated polyester resin is cured by W
It is possible to perform PC processing. When the unsaturated polynisder resin is cured by heating in this way, the unsaturated polyester resin that has penetrated into the wood is completely cured because it is less affected by oxygen in the air, and the unsaturated polyester resin on the surface of the wood is cured. The curing of the polyester tree layer is accelerated by the condensing agent penetrating the surface of the wood T4, making it possible to cure the unsaturated polynisder resin without leaving an uncured layer on the surface. Therefore, when sanding and finishing the surface of wood, the problem of clogging of the sander is eliminated. [Example] Next, the present invention will be explained with reference to an example. Example: 100 parts by weight of unsaturated polyester resin P-852 (manufactured by Nippon Shokubai Kagaku Co., Ltd.), 50 parts by weight of styrene monomer (manufactured by Nippon Shokubai Kagaku Co., Ltd.), and 5 parts by weight of henzoyl perogysite (manufactured by Nihon Yushi Kagaku Co., Ltd.) An unsaturated polyester resin impregnation solution was prepared by blending. An oak veneer with a thickness of 3 mrn was immersed in this unsaturated polyester resin impregnating solution, and the pressure was reduced to 15 Torr and maintained for 2 hours, thereby impregnating the unsaturated polyester resin into the oak veneer. Next, as a condensing agent, Zeller (Nippon Shokubai Ka7 Co., Ltd.) was prepared in a 20% acetone solution.
After immersing the oak veneer in this condensing agent for 5 to 6 seconds, it was left to stand for 1 hour to allow the condensing agent to penetrate into the surface of the oak. Next, while heating this to 150"C, 10kg/cm'
The unsaturated polyester resin was cured by pressing at a pressure of 3 minutes. When sanding the surface of the wood treated with WPC by penetrating unsaturated polyester resin as described above, the surface of the wood was completely dry, and the powder produced by sanding was smooth. 1 go for sander 5
The sander did not get clogged until the length of 00~(ioOm). Comparative Example The oak W board was unsaturated in the same manner as in the example except that the treatment using the condensing agent was not performed. Polyester resin was treated with WPC.In this comparative example, the surface of the wood was not completely dry and had a sticky feel, and when it was sanded, it got tangled with the sander, resulting in 10 to 25 m long pieces of wood. When sanding the surface, only one layer appeared on the sander.In addition, when sanding the surface of an untreated oak material, no clogging occurs up to 1,500 to 2,000 meters. Effects of the Invention] As described in the second series, in the present invention, the unsaturated polyester resin is infiltrated into the wood, the condensing agent is infiltrated into the surface of the wood, and the unsaturated polyester resin is cured by heating. As a result, the unsaturated polyester resin that has penetrated into the interior of the wood is completely cured due to less influence of oxygen in the air, and the unsaturated polyester resin on the surface of the wood has penetrated into the surface of the wood. Curing is accelerated by the condensing agent contained in the resin, and it is possible to cure the unsaturated polyester resin without leaving an uncured layer on the surface. I wonder if it's a problem.
