三元乙丙橡胶与未处理聚酯帆布的粘合性能研究

研究过氧化二异丙苯（DCP）和马来酰亚胺类物质（M）对三元乙丙橡胶（EPDM）与末处理聚酯帆布粘合性能的影响。结果表明：采用DCP为引发剂、M为交联剂的硫化体系所制备的EPDM硫化胶具有较好的物理性能，在常温和200 ℃下与末处理聚酯帆布的粘合强度较高；当DCP/M用量比为0.75/3时，硫化胶的高温粘合强度达到耐热输送带的T3等级。;The effect of dicumyl peroxide（DCP）and maleic imide containing additive M on the adhesionproperty of EPDM and untreated polyester canvas was investigated.The results showed that，EPDM vulcanizate prepared with DCP as initiator and M as crosslinking agent had good physical properties，and the adhesion strength with untreated polyester canvas was high at room temperature and 200 ℃.It was found that when the blend ratio of DCP/M was 0.75/3，the adhesion strength of the vulcanizates at high temperature reached T3 level of heat resistantconveyor belt
