METHOD FOR PRODUCTION OF EMULSIFIED POWDERED RUBBERS

摘要

FIELD: rubber industry. SUBSTANCE: emulsified powdered rubber is obtained by coagulation of latex with alkali-earth metal compounds in presence of antiagglomerants, antioxidants, and optionally fillers, followed by removal of moisture. As latex, mixture of carboxylate and non-carboxylate elastomer latexes is used at their weight ratio between 60:20 and 20:80. EFFECT: avoided on- storage agglomeration effect and increased compaction capacity. 1 tbl, 10 ex
