| 摘 要： | 在ＢＲ／ＣＰＥ自硫化共混物中加入少量氯化亚锡（０．５－２份）能显著促进自硫化反应，增大硫化速度和交联密度，共混物凝胶含量达到９８％，进一步增大氯化亚锡用量对共混物硫化和硫化胶性能无显著影响。ＢＲ／ＣＰＥ共混物用炭黑和白炭黑作补强剂较好，补强剂用量为３０份较合适；ＣＰＥ用量较大，共混物的物理性能较好。

| Abstract: | The self-vulcanization of BR/CPE blend was investigated. It was found that the curing rate and the crosslink density could be significantly increased, and the gel content could reach 98% when the small quantity(0. 5-2phr) of stannous chloride was used in the blend. The curing behaviour of blend and the property of vulcanizate were insignificantly influenced when more than 2 phr of stannous chloride was used. 30 phr of carbon black or silica was suitable for the BR/CPE blend. The better physical properties of the vulcanizate could be obtained when CPE was dominant in the blend. |
