Zusammenfassung:PURPOSE:To provide a wood modifier harmless to the human body and to obtain modified wood enhanced in physical properties, fire resistance and shrinkage resistance by the treatment with the wood modifier. CONSTITUTION:A wood modifier is composed of a mixture of a low-molecular wt. compd. of chitosan and sodium silicate. Sodium silicate is used in an amt. of 0.1-8.0 pts.wt. with respect to 1 pts.wt. of the low-molecular wt. compd. of chitosan. Pref., the mixture is used as an aqueous soln. of pH 5-12. Wood can be easily made inorg. by sodium silicate and this wood modifier acts so as to enhance physical properties such as preservative effect, fire retardance or shrinkage resistance and is used in order to obtain modified wood.
