一种改性氯化聚氯乙烯电缆保护双层波纹管及其制备方法
摘要：
本发明公开一种改性氯化聚氯乙烯电缆保护双层波纹管及其制备方法，一种改性氯化聚氯乙烯电缆保护双层波纹管包括外层和内层，所述波纹状的外层配方为：氯化聚氯乙烯50～60%、聚氯乙烯25～30%、轻质碳酸钙1～5%、重质碳酸钙 0.5～1%、稳定剂 4～8%、聚乙烯蜡1～2%、 ACR加工助剂1～2%、氯化聚乙烯1～5%；所述波纹状的内层的配方为：氯化聚氯乙烯25～30%、聚氯乙烯50～55%、轻质碳酸钙10～15%、重质碳酸钙0.5～1%、稳定剂4～8%、聚乙烯蜡1～2%、ACR加工助剂4～5%。本发明具有拉伸强度高，环刚度高，耐热性好，散热性好且阻燃性好，能够满足非开挖施工要求。
摘要（英）：

The invention discloses a modified polyvinyl chloride cable protective double-layer corrugated pipe and a preparation method thereof. The modified polyvinyl chloride cable protective double-layer corrugated pipe comprises an outer layer and an inner layer, wherein a formula of the corrugated outer layer comprises: 50 to 60% of chlorinated polyvinyl chloride, 25 to 30% of polyvinyl chloride, 1 to 5% of lightweight calcium carbonate, 0.5 to 1% of heavyweight calcium carbonate, 4 to 8% of a stabilizing agent, 1 to 2% of polyethylene wax, 1 to 2% of an ACR processing aid and 1 to 5% of chlorinated polyethylene; and the formula of the corrugated inner layer comprises: 25 to 30% of chlorinated polyvinyl chloride, 50 to 55% of polyvinyl chloride, 10 to 15% of lightweight calcium carbonate, 0.5 to 1% of heavyweight calcium carbonate, 4 to 8% of the stabilizing agent, 1 to 2% of polyethylene wax and 4 to 5% of the ACR processing aid. The modified polyvinyl chloride cable protective double-layer corrugated pipe provided by the invention has the advantages of high tensile strength and ring stiffness and good heat resistance, heat dispersion and flame retardancy, and can meet the requirement of non-excavating construction.
