The effects of ZnO/S curing system,TCY/resin compounding curing system,and Pb3O4/resin compounding curing system on the curing character,physic-mechanic properties,heat ageing resistance and oil resistance of CR/CIIR vulcanizate were studied in this paper.The results showed that the curing speed of the blend was fast,and it's curing torque was high by using ZnO/S curing system.The mechanic properties of the vulcanizate cured with the 3 kinds of curing systems was the same,and the mechanic propertie retention of the vulcanizate cured with TCY/resin compounding curing system was higher than that of the vulcanizate cured with ZnO/S/organic accelerator curing system after ageing,and the oil resistance of the vulcanizate with the later was good.
