摘  要:本研究以不同的用量梯度将不同的加工助剂(氯化石蜡、纳米碳酸钙、氯化聚乙烯)添加至PVC电缆料体系并制备了PVC电缆料样品。使用多项测试表征方法研究上述助剂对PVC电缆料的热稳定性能、力学性能、阻燃性能、外观及加工性能的影响。结果显示,13份的氯化石蜡添加量使得热稳定时间降低了52.9%,低温冲击-断裂根数由19根下降到8根,氧指数由28提升至29.1;引入10份纳米碳酸钙低温冲击-断裂根数便由5根下降至3根,拉伸强度增加了15.5%,产品外观明显得到改善,同时产品加工性能得到提升;氯化聚乙烯由5份到10份的添加,使得复合材料的低温冲击-断裂数量由15根下降到10根,低温冲击-断裂数量下降了33%,抗冲击性能有明显的提升。In this study,processing additives with different gradient amounts(chlorinated paraffin,nano calcium carbonate,chlorinated polyethylene)were added to the PVC cable particle system and PVC cable material samples were prepared.Use multiple testing and characterization methods to study the effects of the aforementioned additives on the thermal stability,mechanical properties,flame retardancy,appearance,and processing properties of PVC cable materials.The results showed that the addition of 13 parts of chlorinated paraffin reduced the thermal stability time by 52.9%,the number of low-temperature impact fractures roots decreased from 19 to 8,and the oxygen index increased from 28 to 29.1;introducing 10 portions of nano calcium carbonate reduced the number of low-temperature impact fractures roots from 5 to 3,increased tensile strength by 15.5%,significantly improved product appearance,and improved product processing performance;The addition of chlorinated polyethylene from 5 to 10 parts reduced the low-temperature impact fractures number of the composite material from 15 to 10,and the low-temperature impact fracture number decreased by 33%,indicating a significant improvement in impact resistance.
