| 中文摘要: |
| 究过氧化物硫化体系对氯丁橡胶（CR）胶料性能的影响。结果表明：当助交联剂为TAIC和DTMPTA时，过氧化物BIPB或双25均可以有效地硫化CR胶料，采用BIPB的CR胶料的硫化速率更快，160 ℃下的t90约为8 min，DTMPTA对CR胶料的硫化促进效果好于TAIC；在助交联剂相同时，采用BIPB的CR胶料的Payne效应更强，不利于填料分散，采用双25的CR硫化胶的拉伸强度、拉断伸长率和撕裂强度大于采用BIPB的CR硫化胶，但硬度和100%定伸应力较小；助交联剂为DTMPTA的CR硫化胶的损耗因子较小，生热更低。 |

| The effect of peroxide vulcanization systems on the properties of chloroprene rubber（CR） compounds was studied.The results showed that，when the coagent was TAIC or DTMPTA，the peroxide BIPB and DBPH could effectively vulcanizate CR compounds.The vulcanization rate of CR compound with BIPB was faster，the t90 at 160 ℃ was about 8 min. DTMPTA had a superior acceleration effect on the crosslinking of CR compound than TAIC.When the coagent was the same，the Payne of CR compound with BIPB was stronger，which was not conducive to filler dispersion，the tensile strength，elongation at break and tear strength of CR compound with DBPH were greater than those of the compound with BIPB，but the hardness and modulus at 100% were lower.The CR vulcanizate with DTMPTA exhibited a lower loss factor，indicating a reduced heat build-up. |
