| 中文摘要: |
| 研究环氧树脂/金属氧化物硫化体系对氯丁橡胶（CR）性能的影响。结果表明：环氧树脂对CR具有增塑和抗焦烧作用；与金属氧化物硫化体系胶料相比，环氧树脂/金属氧化物硫化体系胶料的门尼粘度较小，弹性较好，老化后拉伸强度变化率较小，拉断伸长率变化率较大；随着环氧树脂用量增大，环氧树脂/氧化镁/氧化锌硫化体系胶料的硬度增大，300%定伸应力和拉伸强度变化不大，弹性提高；环氧树脂用量为4~6份的环氧树脂/金属氧化物硫化体系胶料综合性能较好。 |

| The influence of epoxy/metal oxide vulcanization system on the properties of CR compound was studied.The results showed that，epoxy resin provided plasticizing effect and anti-scorch effect to CR compound.Compared with the compound using metal oxide vulcanization system，the Mooney viscosity of the compound with epoxy/metal oxide vulcanization system was lower，the elasticity of the vulcanizates was higher，the tensile strength changed less after aging，and the elongation at break showed more change after aging.With the increase of the epoxy content，the hardness of the vulcanizates using epoxy resin/magnesium oxide/zinc oxide as the curing system increased，the modulus at 300% elongation and tensile strength changed little，and the elasticity was improved.It was found that when the epoxy content was 4～6 phr，the overall performance of the compound was excellent. |
