ADHESIVE FOR WOOD, METHOD FOR PRODUCING PLYWOOD AND METHOD FOR PRODUCING ADHESIVE FOR WOOD

摘要

PROBLEM TO BE SOLVED: To provide a plywood, not generating puncturing, in which sufficient required performance is acquired without applying an adhesive more than the amount of an adhesive necessary for developing strength of required plywood and the adhesive for wood used for wood and to provide a method for producing the adhesive for wood. SOLUTION: The adhesive for wood is obtained by expanding the adhesive composition for wood containing (A) an aqueous solution of a resol phenolic resin and (B) a surfactant. The method for producing the plywood comprises using the adhesive composition for wood. The method for producing the adhesive for wood comprises expanding a mixed liquid composed of (A) the aqueous solution of resol phenolic resin and (B) the surfactant to provide an expanded mixed liquid, adding (C) filler and (D) a curing accelerator to the mixed liquid and expanding the mixed liquid.
