中文摘要:
      在BR/CPE自硫化共混物中加人少量氯化亚锡（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。
英文摘要:
      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.
