摘　　要：以丁腈橡胶和自制的两性共聚吸水树脂为主要原料,以炭黑和白炭黑为补强剂,使用物理共混方法制备出吸水膨胀橡胶,并对其吸水性能,力学性能性能及耐环境性能进行研究.结果表明:当吸水树脂质量份为40 phr,炭黑为20 phr,白炭黑为30 phr时制备的吸水膨胀橡胶的吸水性能和力学性能可达到最佳值,并具有一定的耐高温,耐盐,及耐酸碱腐蚀性能.Water swellable rubber （WSR） was prepared using the nitrile rubber and Self-made amphoteric copolymerization absorbent resin as the raw materials, the charcoal black and white charcoal black as reinforcing agent by the way of physical mix. The water absorbency, mechanical properties and environmental resistence of WSR was investigated. The results showed that the water absorbency and mechanical properties of the WSR can achieve the optimal value when the contain of absorbent resin was 40 phr, charcoal black was 20 phr and white charcoal black was 30 phr, and the rubber have certain performance for high temperature resistance, salt tolerance, acid and base resistance.
