摘要
采用不同种类白炭黑与同种炭黑作为双相填料填充溶聚丁苯橡胶(SSBR)与顺丁橡胶(BR)共混胶,研究了不同白炭黑与SSBR/BR共混胶间相互作用对其磨耗性能的影响规律。结果表明,在Akron磨耗测试条件下,炭黑/白炭黑双相填料填充的SSBR/BR共混胶主要经受磨粒磨耗和卷曲磨耗的耦合作用。当白炭黑平均粒径增大且粒径分布不均匀时,白炭黑与橡胶基质间的相互作用较弱,硫化胶硬度和磨耗性能下降,在磨耗耦合作用机理中卷曲磨耗所起的作用越来越大。
Solution polymerized styrene-butadiene rubber (SSBR) and cis-1, 4-polybutadiene rubber (BR) were filled with the dual phase filler consisted of different kinds of silica and the same kind of carbon black (CB), and effect of interaction between different silica in the dual phase filler and SSBR/BR blends on abrasion resistance of the blends were investigated. The results showed that in Akron abrasion test, the specimens of CB/silica dual phase fillers filled SSBR/ BR blends mainly experienced the coupling effect of abrasive wear and curling wear. When the average particle size of silica enlarged and the particle size distribution was inhomogeneous, the interaction of silica with rubber matrix weakened, both the hardness and abrasion resistance of vulcanizates decreased, and the effect of curling wear became increasingly stronger in the coupling mechanism of abrasion.
