摘　　要：对比了山梨醇类成核剂(成核剂A)和有机磷酸酯盐类成核剂(成核剂B和成核剂C)对高光泽抗冲聚丙烯(PP)的刚性、韧性、耐热性、表面光泽度等性能的影响,并研究了纳米橡胶颗粒含量对样品性能的影响。结果表明:随着橡胶相含量的降低,样品的刚性和光泽度均逐渐提高,热变形温度显著增大,但冲击强度逐渐降低。当成核剂质量分数为0.10%时,成核剂B和成核剂C均能够明显提升PP的刚性、耐热性能和光泽度,成核剂A对PP的增刚增亮效果不理想。随着纳米橡胶含量的降低,样品的刚性、耐热性、光泽度均逐渐升高,韧性逐渐变差。The effects of sorbitol nucleating agents(nucleating agent A) and organic phosphate salt nucleating agents(nucleating agent B and nucleating agent C) on the rigidity, toughness, heat resistance, surface glossiness and other properties of high glossiness impact polypropylene(PP) were compared, and the effect of the amount of nano-rubber particles on sample properties was studied. The results show that as the rubber phase content decreases, the rigidity and glossiness of the sample gradually increase, and the thermal deformation temperature significantly increases, but the impact strength gradually decreases. When the mass fraction of nucleating agent is 0.10%, nucleating agent B and nucleating agent C can significantly improve the rigidity, heat resistance and glossiness of PP. Nucleating agent A does not have an ideal effect on increasing the rigidity and brightness of PP. As the content of nanorubber decreases, the rigidity, heat resistance and glossiness of the sample gradually increase while the toughness gradually deteriorates.
