| 中文摘要: |
| 研究不同防焦剂对采用硫黄硫化体系、硫载体硫化体系和过氧化物硫化体系的三元乙丙橡胶（EPDM）的焦烧性能和物理性能的影响。结果表明：防焦剂E/C，CTP，E-80和DZ-01有效成分用量为0. 5份时，对采用3种硫化体系的EPDM焦烧均起到延迟作用，防焦剂E/C的防焦效果最显著；添加防焦剂E/C的EPDM尤其是采用硫黄硫化体系的EPDM综合性能较好；随着防焦剂E/C用量的增大，采用硫黄硫化体系的EPDM焦烧时间和正硫化时间延长，拉伸性能先改善后变差，抗压缩永久变形性能改善。 |
| 英文摘要: |
| The effects of different anti-scorching agents on the scorch characteristics and physical properties of EPDM compounds which were vulcanized by the sulfur vulcanization system，the sulfur carrier vulcanization system and the peroxide vulcanization system were studied. The results showed that when the content of the active component of the anti-scorching agents，i. e. E/C，CTP，E-80 and DZ-01，was 0. 5 phr， the scorching time of EPDM with any one of those three vulcanization systems was effectively prolonged， and anti-scorching agent E/C provided the most significant anti-scorching effect. The EPDM with anti- scorching agent E/C and especially sulfur vulcanization possessed better properties. It was found that when the addition level of anti-scorching agent E/C increased，the scorching time and optimum curing time of the sulfur cured EPDM were extended，the tensile properties were improved first and then deteriorated，and the anti-permanent set property was improved. |
