摘要
将球状碳酸钙、片状滑石粉和纤维状凹凸棒土与聚苯硫醚(PPS)树脂熔融共混得到复合材料,采用差示扫描量热仪(DSC)对比了三种填料对复合材料的非等温结晶行为的影响,利用Jeziorny法和Mo法分析了复合材料的非等温结晶动力学,利用Friedman方程计算了复合材料在结晶前期和后期的非等温结晶活化能。结果表明,添加0.5%碳酸钙、滑石粉和凹凸棒土均促进PPS树脂结晶的发生,结晶速率作用效果依次为滑石粉>凹凸棒土>碳酸钙。Jeziorny方程、Mo方程和Friedman方程分析进一步表明三种填料促进PPS树脂的结晶。
Polyphenylene sulfide(PPS)composites were prepared by melt blending with PPS and spherical calcium carbonate,flake talc and fibrous attapulgite,respectively.The influence of different inorganic nanoparticles on non-isothermal crystallization properties of PPS composites were studied by differential scanning calorimeter(DSC).The non-isothermal crystallization kinetics were analyzed by Jeziorny and Mo methods.The value of activation energy for crystallization of PPS composites in early stages and in later stages of crystallization were calculated by Friedman equation.The results show that 0.5%calcium carbonate,talc and attapulgite acting as efficient nucleating agents and the efficiency is decreased as follows:talc>attapulgite>calcium carbonate.The results from Friedman equation,Mo equation and Kissinger equation further verify that the addition of inorganic nanoparticles promotes the non-isothermal crystallization of PPS composites.
