二氧化硅增强丁苯橡胶复合材料的制备与性能研究

he rubber composites filled by silica are ideal materials for producing green tire, which has advantages of low rolling resistance, saving fuel and reducing exhaust emissions. The modification effects of silica in styrene butadiene rubber composites were studied in this paper. The results showed that the addition of EEUG, EPDM-g-MMH and KH-550 could decrease the vulcanization delay, reduce Payne effect, and improve mechanical properties, wear resistance compression fatigue of composites. The composite modified with EEUG got higher mechanical properties, better abrasion resistance and dynamic mechanical properties compared to KH-550 and EPDM-g-MMH.
