There are two types of wood cracking (also called dry cracking) preventive agents: one type that suppresses dimensional changes that occur when wood absorbs and dehumidifies moisture, and the other type that suppresses dimensional changes that occur when wood absorbs and dehumidifies moisture. However, there are some types that form a drying-inhibiting film to prevent this.

防止用水溶剤に関する。Based on the knowledge of the present inventors, it has been found that an aqueous solvent prepared by blending a sodium salt of trichlorophenol in a certain proportion with an aqueous solution of polyethylene glycol can prevent wood from cracking and at the same time has an antifungal effect. That is, in the present invention, the sodium salt of trichlorophenol is contained in a ratio of 1 part by weight or more to 0 parts by weight of polyethylene glycol, and the polyethylene glycol is 6% by weight (

ことが判明した。In the present invention, the polyethylene glycol itself may be of a grade known to have a dimensional stabilizing effect on wood, and #1000 is a good example. It is necessary to mix 1 part by weight or more of trichlorophenol to 1 part by weight of polyethylene glycol, for example, as is clear from the test examples described below. 035.07 parts by weight of trichlorophenol sodium salt for 30 parts by weight of
Even if they are mixed in parts by weight, the desired antifungal effect cannot be obtained; on the contrary,
Compared to the single use of trichlorophenols, the combination with polyethylene glycol is more likely to cause mold growth.
Therefore, it was found that a good antifungal effect can be obtained in the area of the present invention.
