Abstract
The influence of the hyperoxide curing system,sulfur curing system,compound curing sys-tem with sulfur,compound curing system without sulfur on the mechanical properties and process proper-ties of ethylene propylene diene monomer(EPDM)composite material is studied.The results show that the crosslinking density of EPDM composite material prepared by hyperoxide curing system are higher than that of other three composite materials,nevertheless the accelerant agent would affect the crosslinking efficiency of hyperoxide; the tensile strength and compress permanent deformation of EPDM composite material are the best,and the tear strength of EPDM composite material prepared by curing system with sulfur is better than that of EPDM composite material prepared by hyperoxide curing system.Besides,the hyperoxide curing system is easy to cause the product parting line tear,but the compound curing system with sulfur can improve the product surface tear obviously; the sulfur and accelerant agent may easily cause the blooming of EPDM.The compound curing system without sulfur have the best mechanical prop-erties and process properties,and can be widely applied to the formula design of EPDM.关键词
