の複数を併合して採用してもよい。 To impregnate wood with a solution of an alkyl silicate compound, it is sufficient to simply immerse the wood in the above solution, but vacuum impregnation, pressure impregnation, or
Any one of the heat impregnation methods, in which the wood material is immersed in a solution heated to 60 to 90° C., or a combination of two or more of these methods may be employed.
木質材中に含浸されたアルキルシリケート化合
物は、加熱あるいは加水分解等の手法で硬化され
て無機高分子化され、木質材中に定着される。 The alkyl silicate compound impregnated into the wood material is cured by heating or hydrolysis to form an inorganic polymer and is fixed in the wood material.

熱圧して、桧単板中で、アルキリシリケート化合
物が高分子化してシリカゲルとなつた。Example 1 A cypress veneer with a thickness of 4.0 mm was impregnated with an isopropyl alcohol solution containing 25% by weight of an alkyl silicate compound under reduced pressure for 4 hours, and then impregnated with a pressure of 20 kg/cm 2 for 8 hours.
Impregnation rate is 80% by time pressure impregnation (100% by weight of plate material)
An impregnated veneer was obtained in which the alkyl silicate compound was impregnated in an amount of 80% by weight. This is 6
After being air-dried for an hour, it was heated and pressed at a temperature of 150° C. and a pressure of 15 kg/cm 2 for 20 minutes to polymerize the alkyl silicate compound into silica gel in a cypress veneer.

燃やそうとしても炭化するだけであつた。 This impregnated veneer has a slightly increased transparency and depth in appearance, and in terms of physical properties, the surface hardness is 40 to 50 on the Barcall hardness tester (No. 935).
It was significantly improved compared to the untreated Japanese cypress veneer, which had a score of 2 to 3. Furthermore, attempts to burn this impregnated veneer with a burner only resulted in carbonization.
