摘 要: 采用CPVC与PVC共混,研究共混物的力学性能和耐热性,并考察纳米CaCO3对其性能的影响。结果表明:随着CPVC含量的增加,共混物的拉伸强度、弯曲强度和耐热性能都有明显的提高,冲击强度则先增后减;随着CaCO3含量增加,共混物的冲击强度和耐热性能都逐渐提高,但拉伸强度和弯曲强度则呈下降趋势。 Mechanical Properties and heat resistance of CPVC/PVC blends were studied, and the effect of nano- CaCO3 was also studied. It was found that the tensile strength, flexural strength and heat resistance were enhanced significantly while the impact strength first increased and then decreased with the CPVC content increased. The impact strength and heat resistance increased gradually while the tensile strength and flexural strength decreased with the CaCO3 content increased.
