Description of the Related Art Woody materials are used as building materials in houses and structures, and are also frequently used as furniture and other general industrial materials or general civil engineering materials. Most of the deterioration of the wood-based material is caused by food-damaging by wood-destroying fungi or pests, and in order to protect the wood-based material from such deterioration, an aqueous wood preservative or the like is applied to the surface of the wood or the like. There is a way. However, simple application is not enough to achieve long-term preservation, and the most effective method is to inject and infiltrate the preservative into the wood under pressure. Is highly effective against decay and insect damage.

れていなかった。Although such a preservation treatment is suitable for treating materials such as veneer and timber, laminated wood materials such as plywood and laminated timber have a phenol-based or isocyanate-based material for small wood pieces and veneers. Since it is formed by joining and assembling with a thermosetting adhesive such as, the penetration of the preservative into the wood is likely to be uneven, and it is difficult to sufficiently improve the antiseptic performance. Therefore, a method has been proposed in which a wood piece or a veneer before being assembled is preliminarily treated with a preservative and then bonded and assembled using an adhesive. However, when the timber treated with a wood preservative is bonded and assembled, the adhesive strength is weaker than the wood not treated with the wood preservative and it is easy to peel off.
