摘　　要：本文研究了一种实验室合成的新型高阻剂HYJL和过氧化物硫化剂BIBP的用量对CPE/EPD M并用体系体积电阻率的影响。通过相关实验与测试发现:当只减少BIBP的用量或者只增加HYJL的用量时,胶片的体积电阻率都会有相应的提升但提升幅度有限。当减少BIBP用量的同时增加HYJL的用量时,样品的体积电阻率会有比较显著的提升,特别是当减少2份BIBP并加入4份HYJL时样品的体积电阻率提升幅度最大,同时样品的力学性能也有一定程度的提升,并且其浸水后也能保持良好的绝缘性。In this paper,we study the effect of the dosage of a novel laboratory-synthesized highly resistive inhibitor,HYJL,and the peroxide,BIBP,on the system volume resistivity of CPE/EPDM.Through relevant experiments and tests we found that when only the volume of BIBP is reduced or only the amount of HYJL is increased,the volume resistivity of the film will increase accordingly,but the increase range is limited.When reducing the amount of BIBP while increasing the amount of HYJL,the volume resistivity of the sample will be significantly improved,especially when reducing two portion BIBP and adding four portion HYJL will increase the most,and the mechanical performance of the sample will be improved to a certain extent.And it can also maintain good insulation after water immersion.
