摘　　要：将经钛酸酯偶联剂NDZ-101表面处理过的纳米CaCO_3与废旧聚苯乙烯塑料通过共混挤出方法制得废旧聚苯乙烯塑料/纳米CaCO_3复合材料.通过测试分析复合材料的拉伸强度、冲击强度和弯曲强度,复合材料中的纳米CaCO_3的质量分数为5%左右时,所制得的复合材料的弯曲强度和冲击强度有一定的提高.通过热重分析,制得的复合材料的分解温度有一定的提高.同时采用XRD对单体和混合物进行结构表征和分析,纳米CaCO_3能分散到聚苯乙烯基体中.采用SEM对单体和混合物结构进行表征和分析,当纳米CaCO_3的含量低于7.5%时,纳米CaCO_3能较好地分散在聚苯乙烯中.The nano-CaCO3,after being surface treated with titanate coupling agent NDZ-101,and waste polystyrene were used to prepare waste polystyrene plastic/nano-CaCO3 composite material by blending extrusion method.Through test the tensile strength,impact strength and bending strength of the composite material were analyzed and it is found that when the mass fraction of nanometer calcium carbonate in the composite material was 5%,the bending strength and impact strength of the composite material improves to some extent.By thermogravimetric analysis,the decomposition temperature of the composite material had certain improvement.Meanwhile,XRD is used to conduct the structural characterization of the monomer and the mixture and it finds that nanometer calcium carbonate disperses in the polystyrene matrix.The structure of the monomer and the mixture were then characterized and analyzed,and it is found that when the content of nanometer calcium carbonate is less than 7.5%,nano calcium carbonate can be evenly dispersed in the polystyrene.
