摘 要：在电线电缆的绝缘和护套材料中，PVC电缆比较便宜，阻燃性好，加工设备、工艺简单，硬度可调范围广，电绝缘性好，耐油、耐化学试剂机械性能优良，使得它长久以来成为电线电缆行业使用数量最多的材料。 综述了在生产PVC电缆料中的各种添加剂的作用以及对其产品性能的影响，通过对试样的断裂伸长率、拉伸强度、200℃时热稳定时间、老化后拉伸强度、老化后断裂伸长率等性能测试的实验数据和国家标准进行对比找到最佳的配方。同时研究各组分对其产品性能的影响。 研究结果表明：采用以下配方所得的电缆料粒子满足国家的标准：PVC粒料（废旧料）82Kg， PVC树脂粉18Kg， 碳酸钙11Kg， DOP 6Kg， 氯化石蜡 4 Kg，碳黑3Kg，复合热稳定剂1kg，硬石蜡0.1Kg，1801硬脂酸0.15Kg，双酚A 0.2Kg，塑料光亮剂 0.13Kg，硬脂酸铅 0.15Kg可达到GT/T 8815-2002电缆料标准。 关键词：PVC电缆料；废旧电缆皮；再生 |
