摘　　要：在聚氯乙烯(PVC)中添加紫外吸收剂,对其表面进行等离子刻蚀,制备PVC复合电缆材料(FPVC/UV)。结果表明:FPVC/UV-3具有最佳的力学性能,拉伸强度以及冲击强度分别为57.6 MPa和4.13 kJ/m2,表现出最佳的抗老化性能。在抗腐蚀测试中,FPVC/UV-3在10 h腐蚀老化后表现出最佳的性能,质量损失率仅为6.9%,拉伸强度和冲击强度下降率分别为15.4%和11.6%,优于其他材料。FPVC/UV-3表现出优异的耐久性,在60 h腐蚀老化测试下,质量损失率仅为14.23%,具有较强的适用性。Polyvinyl chloride(PVC)composite cable material(FPVC/UV)was prepared by adding ultraviolet absorber into PVC and plasma etching on its surface.The results show that FPVC/UV-3 has the best mechanical properties,the tensile strength and impact strength are 57.6 MPa and 4.13 kJ/m2,respectively,and show the best aging resistance.In the corrosion resistance test,FPVC/UV-3 showes the best performance after 10 h corrosion aging.The mass loss rate is only 6.9%,and the decrease rates of tensile strength and impact strength are 15.4%and 11.6%,respectively,which are better than other materials.FPVC/UV-3 showes excellent durability,and the mass loss rate is only 14.23%under 60 h corrosion aging test,which has strong applicability.
