摘要:
分别采用硫黄硫化、半有效硫化、硫载体硫化、有机过氧化物硫化和复合硫化体系制备三元乙丙橡胶(EPDM)硫化胶,并考察了不同硫化体系对EPDM硫化胶的硫化特性、物理机械性能与电绝缘性的影响。结果表明,EPDM硫化胶交联结构中,过氧化物硫化的EPDM硫化胶具备优异的电绝缘性,但物理机械性能较差;而硫黄硫化的EPDM硫化胶的物理机械性能优异,电绝缘性较差;硫载体硫化和半有效硫化的EPDM硫化胶的电绝缘性与物理机械性能较差。复合硫化体系下,EPDM硫化胶具有优异的电绝缘性,体积电阻率较大,介电损耗与介电常数较小,同时具备优异的物理机械性能。
Abstract:
Ethylene propylene diene monomer (EPDM) vulcanizates were prepared by sulfur vulcanization, semi-effective vulcanization, sulfur carrier vulcanization, organic peroxide vulcanization and composite vulcanization systems respectively. The effects of different vulcanization systems on curing characteristics, physical and mechanical properties and electrical insulation of EPDM vulcanizates were investigated. The results showed that in the cross-linking structure of EPDM vulcanizate, peroxide vulcanized EPDM vulcanizate had excellent electrical insulation, but poor physical and mechanical properties. The sulfur vulcanized EPDM vulcanizate had excellent physical and mechanical properties but poor electrical insulation. The electrical insulation and physical and mechanical properties of EPDM vulcanizates vulcanized with sulfur carrier and semi- effective vulcanization were poor. In the composite vulcanization system, EPDM vulcanizate had excellent electrical insulation, large volume resistivity, small dielectric loss and dielectric constant, and excellent physical and mechanical properties.
