摘　　要：用增容剂和聚乙二醇(PEG)改善聚丙烯酸钠(PAAS)与氯丁橡胶(CR)的界面相容性,将吸水树脂PAAS与CR共混制备吸水膨胀橡胶。通过测定吸水性能和力学性能研究各因素对橡胶性能的影响规律。结果表明体系中加入适量甲基丙烯酸缩水甘油酯(GMA)的烷烃共聚物、PEG、CaCO3及γ-甲基丙烯酰氧基丙基三甲氧基硅烷(KH-570)均有利于提高橡胶的吸水膨胀性能和力学性能。扫描电镜(SEM)表明,吸水树脂在橡胶网络中分散比较均匀,界面相容性好。The water swelling rubber was preparated by water swell resin PAAS and chloroprene rubber（CR）by blending process.The compatibility of PAAS and CR was improved by using compatibilizer and PEG.Research focus was put on the influence of various factors on the water absorption and mechanical properties of rubber.The result showed that the properties of rubber raised by adding a certain amount compatibilizer,PEG,CaCO_3 and KH-570.SEM pictures showed that the resin dispersed in the rubber network and the interface compatibility of PAAS and CR was good.
