METHOD OF PREPARING ANTIAGGLOMERATOR

摘要

rubber industry. SUBSTANCE: invention relates to preparation of calcium stearate-based antiagglomerator that can be utilized in production of synthetic rubbers. Preparation involves consecutive interaction of stearic acid with alkali and calcium chloride solutions leading to isolation of calcium stearate suspension, said stearic acid being preliminarily fed into an aqueous medium at temperature 55-65 C and stearic acid-alkali reaction product being heated to 75-85 C and diluted by 1.4-2.5 times. Resulting suspension has particle size 100-500 mcm and allows preparation of stable synthetic rubber pulp with homogeneously distributed antiagglomerator. EFFECT: reduced consumption of antiagglomerator and reduced Mooney viscosity factor drop on drying machines. 1 tbl, 18 ex
