摘要： 选择3种不同结构的丁苯橡胶为基体，研究了白炭黑用量以及白炭黑与橡胶间的相互作用对硫化胶阿克隆（Akron）磨耗和DIN磨耗性能的影响规律。研究结果表明，溶聚丁苯橡胶SSBR72606与白炭黑相互作用最强，SSBR2557A次之，而ESBR1502最低。对于Akron磨耗，ESBR1502达到最高耐磨性时白炭黑用量为60份，而SSBR2557A为50份，SSBR72606为40份。这说明与白炭黑作用力越强，达到最佳耐磨性时白炭黑的用量越少。对于DIN磨耗，随白炭黑用量的增加，3种硫化胶的耐磨性能提高，但当白炭黑用量高于40份时，白炭黑用量再增加对3种硫化胶的耐DIN磨耗性能影响不大。

Abstract: Three kinds of SBR with different structures were used as matrix, and the effects of silica contents and interaction of rubber/SiO2 on their Akron and DIN abrasion resistance were investigated. The results indicated that the interaction between SSBR72606 with silica was the strongest, and ESBR 1502 was the weakest, SSBR2557A was the middle. For ESBR1502, the loaded silica was 60 phr when its Akron abrasion resistance was the best, and it was 50 phr for SSBR2557A, 40 phr for SSBR72606. These results indicated that the stronger the interaction of rubber/SiO2, the smaller the loaded silica when abrasion resistance reached the highest value. The DIN abrasion resistance of these three SBR vulcanizates improved with SiO2 content increasing, however it improved very little when the loaded SiO2 was over 40 phr.

Key words: SBR; silica; abrasion resistance
