AQUEOUS COMPOSITION OF THERMAL REACTION TYPE

摘要

PURPOSE:To obtain an aqueous composition of thermal reaction type improving water resistance, solvent resistance and adhesiveness of synthetic high polymer useful as impregnating resin and adhesive, containing a blocked isocyanate compound, an aquosity forming auxiliary and water. CONSTITUTION:10-60wt.% blocked isocyanate compound obtained by blocking isocyanate group of a diphenylmethane diisocyanate compound containing >=12% isocyanate group with an oxime compound is blended with 0.1-18% aquosity forming auxiliary and the rest of water to prepare the aimed substance. An ordinary emulsifying device or dispersing device is used in the preparation and average particle diameter is <=10mu. The blocked isocyanate compound is obtained by reaction of isocyanate group in an inert solvent at normal temperature - 100 deg.C.
