限られるという基本的な問題があった。2. Description of the Related Art Wood, which is widely used as a material for construction materials and crafts, has the purpose of improving various properties such as water resistance, fire resistance, decay resistance, dimensional stability, and abrasion resistance. It is practiced to impregnate various high-molecular compounds, low-molecular compounds, chemicals, and treating agents such as inorganic substances. However, the treating agent containing a polymer compound as a main component cannot impart water resistance to wood because the polymer compound has a too large molecular size to be impregnated into the cell walls of wood. Polymerization was also attempted by impregnating a polymer compound monomer, but because the monomer is hydrophobic, it cannot be impregnated into the cell wall of wood, and the polymerization reaction is difficult to complete. There was a problem of leaching. Furthermore, many of the methods for impregnating low molecular weight compounds, chemicals, inorganic substances, etc., including the above-mentioned polymer compounds, have the drawback that the original wood texture of the wood is impaired by the impregnation treatment. There was a basic problem that was limited.

There are many problems in practical use due to the drawbacks such as the use of a large amount of acetic anhydride, several reaction steps, and the need to thoroughly wash the acetic acid produced in the reaction process with water. .

The application of the silane coupling agent and the organic silanes disclosed in No. 704 is expected to be effective in the crosslinkability and water repellency of the organic functional group, so the organic group has a long chain length and the hydrophobicity of the molecule. Therefore, it cannot be impregnated into the cell wall of wood as in the case of the above-mentioned treated material composed of a polymer monomer, and the reaction of forming a Si—O bond between the OH group and the alkoxy group of wood is slow. Therefore, there was a problem that the expected effect could not be achieved.

It may be impregnated with the vapor of the treatment agent in the vapor phase, or may simply be sprayed or applied on the surface of the wood. The trialkoxysilane in the wood treating agent of the present invention has a very high permeability to wood, and can be easily impregnated into the wood by any method. It is sufficient to impregnate the wood with the wood treating agent of the present invention and leave it at room temperature, but by heating it, the chemical change of the wood treating agent can be promoted and the treatment time can be shortened. The temperature for heating is preferably not higher than the boiling point of trialkoxysilane, and the boiling point of trialkoxysilane is approximately 130 ° C.

を抑制する。Although the mechanism of action of the present invention is not clear, the wood treating agent quickly impregnates the wood part where the cell wall is clogged and the conduit part through which water or the like was flowing, and It is considered that a strong Si—O bond is formed between the OH group and the alkoxy group, and exhibits a water resistance effect. Therefore, when the wood treated with the wood treating agent of the present invention is subjected to a water absorption test, the water absorption weight of the wood increases due to the intrusion of water into the conduit in the very initial short time, but after that, a long time water immersion is performed. However, since the water absorption from the conduit to the wood part does not proceed, the water absorption weight of the wood does not change and the size does not change. In addition, even if it is re-dried after absorbing water, the water in the conduit easily escapes, so that the weight of the wood immediately returns to the weight before the water absorption test, and there is no dimensional change. On the other hand, in the wood part, the cell wall is covered with a strong Si-O bond, so that the propagation of wood-destroying fungi is suppressed, and even when exposed to flames, the phenomenon of ash collapse on the surface due to the progress of combustion is suppressed. Suppresses the progress of combustion to deep wood.
