防虫合板の製造法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides 0゜O-dimethyl()-(J-methyluda-nitrophenyl) which is an active insect repellent ingredient in Hekinanchu.
This invention relates to a method for producing insect-proof plywood by adding a preparation containing lotioate C (hereinafter referred to as fenitrothison) and constructing the plywood by a conventional method.

いる。For our country, which relies on foreign materials for most of its wood resources, the effective use of these resources is an important issue.The import of Nanpo Dohiro tree, which is widely used for lumber and plywood, is increasing from country to country. However, on the other hand, the biggest drawback of South Sea lumber, the damage caused by the dry wood pest, the oyster beetle, has become a serious problem.
すなわち、防虫合板の必要性が免速に高まっているので
ある。In other words, the need for insect-proof plywood is increasing rapidly.

い方法である。Among them, (1) adhesive mixing method is a method of creating self-adhesive plywood by mixing insect repellent into the adhesive. This is the most desirable method from the viewpoint of production efficiency, production efficiency, and production efficiency.

要がある。tた%接着剤の接着力や合板の耐候性が紡虫
剤を混入したことにより一低下しないことが望まれる。However, this method has the disadvantage that the INK does not penetrate into the xylem, so it is necessary to devise ways to ensure that a sufficient amount reaches the xylem. It is desired that the adhesion strength of the adhesive and the weather resistance of the plywood do not deteriorate due to the addition of the insecticide.

必須である。Also, as a requirement when manufacturing plywood, adhesives and insect-proof steel are required.
There are local restrictions such as ensuring that the IK is mixed uniformly and that it does not emit a bad odor, and it is also essential that the insect repellent plywood has sufficient larvae.

Add and mix so that the thickness is between θθt and 1000t K, and apply the adhesive part, apply the adhesive part, laminate it, apply it by cold pressure, leave it to stand, and perform hot pressing according to the conventional method. It was at this point that I discovered that it could be created and completed the present invention.

のである。Furthermore, as is clear from Reference 4J13, when using hydrated steel containing fenitrothion or an emulsion using an unsuitable field [Im property], 7-enitrothion is transferred from the adhesive steel layer in the manufactured plywood to the xylem. Penetration is insufficient. In a prototype plywood made using an appropriate surfactant in the deep layer, it was found that the concentration of 7-nitrothion in the central layer was 3 to 75 times higher than that in the surface layer. This shows that when using chlordane, the ratio is 065 to 3 times (N71 Wood Science Society lecture, behavior of chlordane in insect-proof plywood, Takashi Nishiki-1/31K (/?7JI 1, significantly different from fenitrothion). .Practically speaking, oyster bark beetles attack the surface water area, but in practical terms, there is a lot of insect damage in the middle plate where sapwood is often used, and from an environmental hygiene perspective, a large amount of medicinal steel comes out on the surface layer, which can be harmful to the human body through contact with Fi. Considering that the fenitrothion preparation according to the present invention is not suitable for use due to the risk of being touched and removed from the cavity, this phenomenon of 111111 distribution of fenitrothion when using the fenitrothion preparation according to the present invention is very favorable. In order to reach %fenitrothion and maintain biological activity, the amount of fenitrothion added to plywood must be 700974 or more, more preferably -00f/- to 1000F/-.
This upper limit was set in consideration of the decrease in adhesive strength of plywood.
