SURFACE PREPARATION METHOD FOR WOODY MATERIAL, SURFACE PREPARATION AGENT FOR WOODY MATERIAL, AND WOODY MATERIAL

摘要

PROBLEM TO BE SOLVED: To allow for the uniform application of a water soluble coating on a woody material subjected to nonflammable, semi-nonflammable, or flameproofing treatment using water soluble chemicals of boric acid and phosphoric acid, to suppress the spouting of a chemical, and to improve alga repelling properties, termite repelling properties, and antiseptic properties.;SOLUTION: The woody material subjected to nonflammable, semi-nonflammable, or flameproofing treatment by an aqueous solution of phosphoric acid or boric acid is coated with, immersed in, or impregnated with a solution in which zirconium ammonium carbonate is dissolved or a solution in which at least one of an alkaline earth metal, titanium, manganese, iron, cobalt, nickel, copper, silver, zinc, or aluminum salt, oxide, hydroxide, or complex is dissolved. In the treatment by the zirconium ammonium carbonate solution, irrespective of the implementation of the nonflammable, semi-nonflammable, or flameproofing treatment, the woody material is coated, immersed, or impregnated.;COPYRIGHT: (C)2008,JPO&INPIT
