| 摘 要： | 采用湿法挤出工艺,即将乳液聚合合成的丙烯腈-丁二烯-苯乙烯(ABS)接枝共聚物经凝聚和过滤后得到的ABS接枝共聚物湿粉料与苯乙烯-丙烯腈共聚物(SAN)以一定的比例投入湿法挤出机内挤出造粒,直接获得了ABS树脂。考察了ABS接枝共聚物湿粉料含水量、ABS树脂中橡胶含量、抗氧剂含量、挤出机温度及螺杆转速等因素对ABS树脂力学性能的影响。结果表明,挤出温度过高明显引起物料降解,ABS树脂的冲击强度减小,拉伸强度降低;ABS接枝共聚物湿粉料含水量对ABS树脂的性能没有明显影响;透射电子显微镜分析表明,橡胶粒子在SAN基体中分散均匀;湿法挤出的最佳工艺参数为,挤出温度:180℃,螺杆转速:200 r/min,抗氧剂含量:0.154%(质量分数,下同)。

| Abstract: | In this paper,wet extrusion process was used to prepare ABS resin.Firstly,ABS graft copolymer wet powder was synthesized by emulsion polymerization,and then filtering,dewatering.Secondly,the ABS graft copolymer wet powder was blended with SAN and then extruded in wet extruder,getting the ABS resin.The effects of moisture,rubber content,antioxidant content,and extrusion temperature and screw rotating speed on mechanical properties of ABS resin were studied.It was found that a too high extrusion temperature c... |
