摘　　要：介绍了采用硅烷交联聚乙烯制备交联聚乙烯方法,利用性能测试的方式验证材料的耐湿热性能。为保证测试结果的精准度,向材料中混入聚乙烯基吡咯烷酮或混杂纤维,并将混合后的材料置于沸水内持续煮200 h,以此模拟真实的湿热老化环境。通过对测试结果进行分析可知,在复合材料中添加6%聚乙烯基吡咯烷酮,或者添加混杂纤维复合材料厚度在6.6 mm时,交联聚乙烯的性能达到最佳。In order to improve the production efficiency and performance of wire and cable,the crosslinked polyethylene material as the main research object,using silane crosslinked polyethylene technology to complete the preparation of crosslinked polyethylene material.In order to ensure the accuracy of the test results,polyethylene pyrrolidone or hybrid fiber were mixed into the material,and the mixed material was boiled in boiling water for 200 h,so as to simulate the real humidity and heat aging environment.Through the analysis of the test results,it can be seen that 6%polyethylene pyrrolidone or 6.6 mm hybrid fiber reinforced can achieve the best performance of crosslinked polyethylene.
