| 摘 要： | 热塑性塑料成核剂是一种促进聚合物结晶并改善其晶粒结构的改性剂.在热塑性树脂中加入成核剂可以提高其结晶速度,缩短成型周期,改善制品的机械性能和热性能.热塑性树脂的结晶改性是实现其高性能化、高功能化的重要途径.本研究介绍了苯甲酸钠的合成方法及主要物性.苯甲酸钠作为分散型成核剂,可以提高聚丙烯的结晶温度,缩短结晶时间;在高压下成型,还可以改变聚丙烯的晶型;而作为PET和PEN的成核剂,则是通过与聚酯发生化学反应,通过"化学成核"而起作用.苯甲酸钠成核剂与其他成核剂相比,具有合成工艺简单、成本低、无毒、易储存等优点,本研究还指出,延长苯甲酸钠成核剂产品寿命的方向是提高产品纯度、降低粒度,与其他成核剂复配使用.
