The influences of coagulant dosage, coagulation temperature and stirring rate on coagulation effect were studied through the analysis of coagulation mechanism of high rubber acrylonitrile-butadiene-styrene terpolymer(ABS) latex. The optimum process conditions were determined based on the practical production situation of the industrial plant as follows: coagulant dosage 35-45 kg/t, coagulation temperature 76 ℃and stirring rate 100 r/min. A suggestion was presented for improving the existing coagulation process.%通过分析高胶丙烯腈-丁二烯-苯乙烯三元共聚物(ABS)的胶乳凝聚机理,研究了凝聚剂用量、凝聚温度和搅拌器转速对凝聚效果的影响.结合装置实际生产情况得出最佳凝聚工艺条件:凝聚剂用量35-45 kg/t,凝聚温度为76℃,搅拌器转速为100 r/min.对现有凝聚工艺提出了改进建议.
