摘　　要：研究了白炭黑用量对溴化丁基(BIIR)/顺丁橡胶(BR)并用胶性能的影响。结果表明,随着白炭黑用量增加,胶料的正硫化时间和交联程度先增加后减小,拉伸强度、撕裂强度、断裂伸长率以及磨耗性能,均随着白炭黑用量增加先升高后下降,硬度和门尼粘度呈逐渐增大的趋势。The influence of silica white loading level on properties of the BII1UBR blends was investigated. The results revealed that both cure time and crosslink density increased at the beginning and then decreased with the increase of silica white loading. Tensile strength, tear strength and elongation at break as well as abrasion resistance firstly increased and then decreased. Hardness Shore A and Mooney viscosity increased.
