木質材の製造方法に関する。BACKGROUND OF THE INVENTION The present invention relates to a method of impregnating and hardening a wood material containing a large amount of quinones with a radical polymerization type resin solution.
The present invention relates to a method for manufacturing a synthetic-resin-injected wood material having improved durability, hardness, and cosmetic properties.

This is called a radical polymerization type resin liquid such as acrylic or polyester resin is injected into a void portion in the wooden material and cured to improve hardness and durability, which are defects of the wooden material. Such WPC materials are widely used for floor materials, stairs, furniture surface materials, and the like.

填化を図るためである。The reason for using a radical polymerization type resin liquid as a synthetic resin liquid to be injected into a wood material is that this resin not only has a high heat-curing speed and good productivity but also has a solvent such as styrene or methyl methacrylate. At the same time, by adding a compound that is capable of radical polymerization and curing itself, the viscosity of the resin liquid can be reduced to facilitate penetration into the wood material.Furthermore, the generation of gas during heat pressure can be minimized. This is to prevent uneven distribution of punctures and resins and to increase the resin filling in the wood material.

より重合阻害されて充填ムラが生じたり、樹脂が完全に
硬化しなくてベトツキが残る等の問題点がある。However, wood cedars, zelkova, walnuts, and the like, which are high-grade precious woods used for high-quality building materials and furniture, contain a large amount of quinones in their woody materials. Therefore, when a radical polymerization type resin solution is directly injected into such a wood material, there is a problem that polymerization is inhibited by quinones and uneven filling occurs, and the resin is not completely cured and stickiness remains.

There is. Therefore, even if an attempt is made to extract the polymerization-inhibiting component in advance with hot water, alcohol, or the like, it cannot be completely removed from the complicated and fine structure of the wooden material, and the above problem cannot be solved.

A wood-based material containing a large amount of quinones that cause polymerization inhibition when a polymerized resin solution is injected, a condensed polymerized resin solution such as a phenolic resin is added in advance to the cell lumen of the wood-based material. And then impregnating and curing the radical polymerization type resin liquid into the voids.

It reacts and denatures to become a substance that does not inhibit radical polymerization.

ジカル重合を阻害しなくなる。Further, since the condensation polymerization resin solution is injected in the form of an aqueous solution, it easily penetrates into the cell walls of the wooden material which is hydrophilic and volatilizes the water after the infiltration, so that the cell cavity of the wooden material can be removed. It cures while filling the small voids in the cell wall with the large voids remaining. for that reason,
The inhibitor is blocked so as not to float and does not inhibit the radical polymerization.

Thus, a resin-injected wood material that prevents cracks and contaminants from penetrating can be obtained.

An aqueous solution of a condensation polymerization resin adjusted to have a non-volatile content of 40% by weight or less, preferably 5 to 25% by weight, by adding an appropriate amount of water to a fiber is prepared. It is poured into undried wood having a water content below the saturation point (even a water content of about 50% is acceptable). As the condensation polymerization resin, urea resin, melamine resin, phenol resin, furan resin, and the like are used, and are injected into the wood material as an aqueous solution adjusted to the above concentration.
If this is the case, impairment of the impregnation of the radical polymerization type resin solution to be described later occurs, so the content is adjusted within the above range.

れる。When an acid such as toluenesulfonic acid, xylenesulfonic acid, benzenesulfonic acid or the like is added to the aqueous solution of the condensation polymerization resin, the low molecular weight compound in the wood material component is hardly modified into a quinone structure together with the catalytic action. It is considered to be effective in preventing the formation of radical polymerization inhibitors.

A method and conditions suitable for the shape and size of the material, permeability, and tree species may be appropriately selected so as to be impregnated. In addition, as the polycondensation resin to be injected, a low molecular weight resin having a molecular weight of 200 or less is used to facilitate the penetration of the wood material into the cell wall. On the other hand, the wood material to be injected may be any of a thin plate such as a veneer, a thick lumber such as a square or plate material, a hollow material, a plywood, a laminated wood, and the like.

For example, the aqueous solution of the condensation polymerization resin easily penetrates.

ては熱風ドライヤーを用いて行ってもよい。After injecting the aqueous condensed polymer resin solution into the wood material, the resin-injected wood material is heated while paying attention to the occurrence of warpage, cracks, etc., to volatilize the water in the aqueous condensed polymer resin solution impregnated in the wood material. Exclude. In addition, you may perform using a hot-air dryer as a heating and drying means.

Thus, voids (cell lumens) not filled with the resin are formed, while small voids in the cell wall remain filled with the resin.

This is preferable because it does not occur. Such heating and drying treatments are 80-160 ° C depending on the thickness of the wood.

寸法安定性や防腐防虫性が確保できる。When the rate of weight increase of the wood material after the injection polymerization of the condensation polymerization resin solution is 5 to 40%, preferably 10 to 25%, the presence of voids such as cell cavities in the wood material is maintained. As a result, the condensation polymerization resin is sufficiently injected into the wall and hardened without impeding the injection of the later-described radical polymerization type resin solution, so that good dimensional stability and antiseptic and insect repellency can be secured.

Therefore, the concentration of the aqueous solution of the condensation polymerization resin is limited to the above range of 40% by weight or less. The adjustment of.
