摘　　要：以丁苯橡胶(SBR)和自制的高吸油树脂(OAR)为主要原料,以高耐磨炭黑(HAF)为补强剂,以石油树脂为软化剂,使用物理共混方法制备遇油膨胀橡胶(OSR).兼用数学方法对其吸油性能和力学性能进行了研究,结果表明:随着高吸油树脂用量的增加,OSR的吸油性能提高,力学性能降低;随着高耐磨炭黑用量的增加,OSR的吸油性能和断裂伸长率降低,硬度和拉伸强度提高.所建立的数学方程,为预测OSR的性能及优化配方提供了理论参考.Oil swelling rubber （OSR） was prepared by the way of physical mix, using the polymerized styrene butadiene rubber（SBR） and high oil absorption resin（OAR） as the matrix material,high abrasion furnace black （HAF） as a reinforcing agent,petroleum resin for softener. Oil absorption and mechanical properties were detected by mathematical methods. The results show that： With the amotmt of high oil absorbing resin increasing, oil absorption of OSR enhances but the mechanical properties decrease; with the increasing of high abrasion furnace black dosage, the oil absorption and the elongation of OSR reduce, tensile strength and hardness increase. This mathematical equation provides a theoretical basis to predict OSR performance and optimization formula.
