氯化聚乙烯电缆料的配方优化

Formulation Optimization of Chlorinated Polyethylene Cable Compound

通过正交试验对氯化聚乙烯(CPE)电缆料配方进行优化,以CPE/三元乙丙橡胶(EPDM)为基相,硫化剂DCP/助交联剂TAIC为硫化体系、炭黑为补强剂,并配以适量的阻燃剂和增塑剂,制备阻燃型电缆料。结果表明:电缆料的最佳配方为CPE 70,EPDM 30,炭黑10,氧化镁5,抗氧剂2,增塑剂DOP 5,硫化剂DCP 4,助交联剂TAIC 2.5,胶料综合性能较优,且满足电缆料要求。

The formulation of chlorinated polyethylene（CPE） cable compound was optimized through the orthogonal experiment test,the flame retardant cable compound was prepared with CPE/EPDM as based resin,DCP/TAIC as curing system,carbon black as reinforcing agent,and proper amount of flame retardant and plasticizer. The results showed that,the optimized formulation of cable compound was CPE 70,EPDM 30,carbon black 10,MgO 5,antioxidant 2,DOP 5,DCP 4,TAIC 2. 5. The comprehensive properties of the optimized formulation compound were excellent and met the requirements of the cable compound.
