摘　　要：采用辐射硫化技术制备了氯丁 /聚丙烯酸钠遇水膨胀橡胶 ,考察辐射剂量、组成等对遇水膨胀橡胶机械性能、膨胀性能的影响。遇水膨胀橡胶的吸水膨胀率及平衡膨胀率随辐射剂量增加而逐渐下降 ,随聚丙烯酸钠相对含量增加而上升 ;其机械性能在辐射剂量约 4 0kGy时最佳 。A new radiation vulcanization process of water -swellable rubber comprised of a chloroprene rubber and crosslinked polyacrylate,has been performed by radiation vulcanization.The results indicate that the water-swellable rubber vulcanized at 40kGy with the weight proportion of the chloroprene rubber to the polyacrylate sodium 4:3 has the best comprehensive properties.
