核壳结构SAM增韧聚碳酸酯树脂的研究

Study on Core-shell SAM Modifier Toughening Polycarbonate Resin

电动汽车具有零排放、能源利用率高、低噪音等特点,得到国家政策的大力扶持,发展迅速。但是,目前电动汽车充电基础设施并不完善,限制了充电汽车的普及。充电桩是电动汽车充电基础设施至关重要的一环,由于其使用环境的特殊性、差异性要求其壳体材料具有良好的机械性能和耐低温冲击性能。本文采用新型有机硅-丙烯酸酯-甲基丙烯酸甲酯增韧剂(SAM)对双酚A型聚碳酸酯(PC)进行增韧改性,改善PC缺口敏感性,提高PC韧性特别是低温冲击性能,为电动汽车充电桩用耐寒PC材料的开发提供参考,推动电动汽车基础设施的建设,助力电动汽车的普及。

With zero emission, high energy utilization rate, low noise and other characteristics, electric vehicle is developing rapidly and it is supported by government policies. However, the charging infrastructure is not fully functional at present, which limiting the popularity of electric vehicle. Charging station is a vital part of the electric vehicle charging infrastructure and it is used in special and different environment. Therefore, the shell material of charging station requires good mechanical properties and low temperature impact resistance. In this paper, polycarbonate resin was modified by silicone-acrylate-methyl methacrylate toughening agent in order to reduce notch sensitivity and improve toughness, especially the low temperature impact performance. On the one hand, this work can provide reference for the research and development of electric vehicle charging station PC material with low temperature resistance. On the other hand, it can promote the construction of electric vehicle infrastructure and improve the popularity of electric vehicles.
