研究了氯化聚乙烯橡胶（CM）的主要硫化体系对氯丁橡胶（CR）的硫化特性的影响，并与金属氧化物(ZnO/MgO)的效果进行对比，发现CR的焦烧时间明显缩短，硫化速度显著提高，硫化体系NA-22（亚乙基硫脲）/S （硫磺）、FSH（三唑二巯基胺盐）和TCHC（复配型交联剂EataMix）都有明显的返原现象。NA-22/S、PT75（噻二唑衍生物类化合物EataVulc）/903（噻二唑衍生物类化合物EataAccel）和TCHC硫化的CR/CM出现明显的硫化不同步现象。DCP（过氧化二异丙苯）/TAIC、FSH和TCY（三巯基均三嗪）硫化的CR/CM，硫化同步性较好。对于纯CR，硫脲类和TCHC硫化胶料的拉伸强度较高，六种硫化体系的硫化胶物理性能都低于金属氧化物硫化胶。共混胶中NA-22/S和TCHC类拉伸强度较高（达22.8 MPa），金属氧化物和TCY拉伸强度较低。NA-22/S、DCP/TAIC、PT75/903、FSH和TCHC硫化的共混胶的力学性能与硫化CR相近，显示出较好的共混性能。

The properties of CR prepared by the primary vulcanization system of CM were investigated, and the comparison with a metal oxide was also studied. The results showed that, CR had significantly shorter scorch time and the higher vulcanization rate. NA-22/S, FSH and TCHC vulcanization system had obvious reversion phenomenon. The Vulcanizing processing of CR/CM blends vulcanized by NA-22 / S, PT75/903 or TCHC were not synchronous. Those with DCP/TAIC, FSH and TCY were better in synchronism. For individual CR, NA-22/S and TCHC system had higher tensile strength, and the physical properties of all the six kinds of vulcanized rubber were worse than metal oxide vulcanized one. NA-22/S and TCHC in blends had higher tensile strength(22.8 MPa), and metal oxides and TCY in blends had lower tensile strength. For NA-22/S, DCP/TAIC, PT75/903, FSH and TCHC, the mechanical properties of vulcanized blends were similar with those of individual CR, and showed good performance.
