摘　　要：采用自制的新型纳米“核-壳”改性剂,与传统氯化聚乙烯(CPE)/丙烯酸树脂(ACR)增韧体系进行对比,研究了不同增韧体系对硬质聚氯乙烯(PVC)改性的影响。通过转矩流变分析和动态机械热分析研究了不同增韧体系复合材料的加工性能和松弛性能。结果表明:新型纳米“核-壳”改性剂改善了复合材料的缺口冲击强度和加工性能,同时显著提高了复合材料的拉伸强度和加工性能、模量和玻璃化转变温度。The new nano-core-shell modifier was used as a comparison with the traditional chlorinated polyethylene(CPE)/acrylic resin(ACR)toughening system to study the effect of different toughening systems on the modification of rigid polyvinyl chloride(PVC).With torque rheology and dynamic mechanical thermal analysis,the processability and relaxation properties of composite materials with different toughening systems were characterized.The results show that the new modifier effectively improve the notch impact strength and processing properties of PVC,and it can significantly increase the tensile strength,glass transition temperature and modulus of the composite material.
