摘　　要：以丁苯橡胶(SBR)为主要原料通过不同硫化体系制备了相应遇油膨胀橡胶(OSR)。研究了普通硫化体系、有效硫化体系、半有效硫化体系和过氧化物硫化体系对OSR性能的影响。结果表明,半有效硫化体系适合制备的多元共混OSR,硫磺用量在1.2质量份左右时,吸油膨胀率达775%左右,拉伸强度为6.8MPa,其综合性能最佳,符合制品要求。Using styrene-butadiene rubber （SBR） as the main raw material the corresponding oil- swellable rubber （OSR）, was prepared by the different type of curing system. The effect of ordinary vulcanization system, effective vulcanization system, semi-efficient vulcanization system and peroxide vulcanization system on OSR performance was inrestigated. The results showed that the semi-efficient vulcanization system prepared diverse blend of oil-swellable rubber, the sulfur content about 1.2, oil ratio of about 775%, tensile strength of 6.8 MPa it nas the its best overall performance, in line with article requirements.
