聚碳酸酯树脂组合物及其制备方法
摘要：
本发明提供了一种聚碳酸酯树脂组合物及其制备方法，该组合物包含按重量份数计的如下组分：聚碳酸酯树脂：20～50份；聚甲基丙烯酸甲酯树脂：5～10；丙烯腈‑丁二烯‑苯乙烯共聚物：5～40份；苯乙烯‑丙烯腈‑甲基丙烯酸缩水甘油酯三元共聚物：5～10份；苯乙烯‑丙烯腈共聚物：20～40份。该树脂组合物的制备方法包括：将PC与PMMA挤出共混获得PC/PMMA树脂组合物；将ABS、SAN与SAG挤出共混获得ABS/SAG树脂组合物；将PC/PMMA树脂组合物与ABS/SAG树脂组合物挤出共混制备聚碳酸酯树脂组合物。与现有技术相比，本发明具有如下优点：聚碳酸酯树脂组合物的界面性能明显改善，界面厚度明显增加，极大地提升了树脂组合物的物理机械性能。
摘要（英）：

The invention provides a polycarbonate resin composition and a preparation method thereof. The composition is prepared from, by weight, 20-50 parts of polycarbonate resin, 5-10 parts of polymethyl methacrylate resin, 5-40 parts of acrylonitrile-butadiene-styrene copolymer, 5-10 parts of styrene-acrylonitrile-glycidyl methacrylate terpolymer and 20-40 parts of styrene-acrylonitrile copolymer. The preparation method of the resin composition comprises the steps that PC and PMMA are subjected to extrusion blending to obtain a PC and PMMA resin composition; ABS, SAN and SAG are subjected to extrusion blending to obtain an ABS and SAG resin composition; the PC and PMMA resin composition and the ABS and SAG resin composition are subjected to extrusion blending to prepare the polycarbonate resin composition. Compared with the prior art, the interface property of the polycarbonate resin composition can be obviously improved, the interface thickness is obviously increased, and the physical and mechanical properties of the resin composition are greatly improved.
