Abstract

DISCLOSED IS A METHOD FOR PRODUCING AN ADHESIVE, WHICH COMPRISES ADDING TO (A) AN AQUEOUS EMULSION, (B) A POLYVINYL ALCOHOL POWDER OF WHICH THE SOLUBILITY IN WATER AT 40°C FOR 1 HOUR IS NOT LOWER THAN 50 % BY WEIGHT AND OF WHICH THE SURFACE TENSION IN THE FORM OF A 1 WT.% AQUEOUS SOLUTION IS NOT LOWER THAN 45 MN/M, TO PREPARE A PRIMARY ADHESIVE INGREDIENT, FOLLOWED BY ADDING THERETO (C) A POLYISOCYANATE COMPOUND. THE PRIMARY ADHESIVE INGREDIENT IS PRODUCED AT LOW TEMPERATURES, AND ITS STABILITY IS HIGH. ALSO DISCLOSED IS AN ADHESIVE COMPRISING (A) AN AQUEOUS EMULSION, (B) A POLYVINYL ALCOHOL HAVING CARBOXYL GROUPS IN AN AMOUNT OF FROM 0.2 TO 5 MOL%, OF WHICH THE SOLUBILITY IN WATER AT 40°C FOR 1 HOUR IS NOT LOWER THAN 50 % BY WEIGHT AND OF WHICH THE SURFACE TENSION IN THE FORM OF A 1 WT.% AQUEOUS SOLUTION IS NOT LOWER THAN 45 MN/M, AND (C) A POLYISOCYANATE COMPOUND. THE ADHESIVE HAS HIGH ADHESIVE STRENGTH, ESPECIALLY HIGH INITIAL ADHESIVE STRENGTH, AND IT’S THE ADHESIVE STRENGTH IS NOT LOWERED IN REPEATED BOILING CONDITIONS. THE POT LIFE OF THE ADHESIVE IS LONG. THE ADHESIVE IS FAVORABLE TO WOOD AND PLYWOOD FOR PRODUCING LAMINATES.
