摘要
研究了再生橡胶(RR)的高性能化策略及反式-1, 4-丁二烯-异戊二烯共聚橡胶(TBIR)/RR并用胶的结构与性能。结果表明,实验用再生橡胶由100份橡胶和58份填料组成;采用100份TBIR与58份炭黑共混制备TBIR母炼胶,90～60份RR与10～40份TBIR母炼胶按比例共混,相比RR硫化胶,RR/TBIR并用硫化胶具有非常优异的综合性能:拉伸强度提高33%～83%,100%定伸应力提高31%～75%,撕裂强度提高39%～76%,邵A硬度提高3%～11%,弹性提高30%～65%,耐磨耗性能提高11%～25%,100%伸张疲劳寿命提高0.5～2.1倍,耐屈挠疲劳裂纹引发性能提高1.0～7.3倍,耐热空气老化性能提高11%～59%,耐臭氧老化性能提高5%～27%,滚动阻力降低20%～42%。通过RR与TBIR简单的物理共混,可实现RR更完善的橡胶网络结构及优异的物理机械性能,为廉价橡胶材料的再生利用提供高性能化方案与策略,赋予再生橡胶更广泛的用途。
The structures and properties of reclaimed rubber(RR) modified with multi-block trans-1, 4-poly(butadiene-co-isoprene) copolymer rubber(TBIR) were researched. The results showed that, the reclaimed rubber used in this experiment was consisted of 100 phr rubber and 58 phr filler. 100 phr TBIR and 58 phr carbon black(CB) were mixed for the TBIR master-batch preparation. 90～60 phr RR and 10～40 phr TBIR master-batch were mixed to prepare the RR/TBIR compounds. Compared with RR vulcanizates, RR/TBIR vulcanizates showed excellent performances, such as improved tensile strength(33% to 83% higher), modulus at 100%(31% to 75% higher), tear strength(39% to 76% higher), shore A hardness(3% to 11% higher), rebound(30% to 65% higher), abrasion resistance(11% to 25% higher), tensile fatigue resistance(0.5 to 2.1 times), flex fatigue crack initiation resistance(1.0 to 7.3 times), hot-air ageing resistance(11% to 59% higher) and ozone ageing resistance(5% to 27% higher), and decreased rolling resistance(20% to 42% lower). The improved polymer networks, filler-polymer interaction and filler distribution of RR was obtained through the simple blending of RR and TBIR. A high performance modification strategy for RR with TBIR is proposed.
