| 摘 要： | 采用原位生成法制备聚丙烯酸钠(PNaAA)／EPDM吸水膨胀橡胶，研究其吸水膨胀性能的影响因素。结果表明，过氧化二异丙苯用量增大，硫化胶的吸水膨胀性能降低，NaAA理论生成量增大，硫化胶的吸水膨胀性能提高，氢氧化钠／AA摩尔比为1～1．2时，硫化胶的吸水膨胀性能较好，水溶液温度高，硫化胶的吸水膨胀率较大，水溶液中Na^ 含量越大，硫化胶(尤其是NaAA理论生成量大时)的吸水膨胀率越小。

| Abstract: | The effective factors on the water-swelling property of in-situ formed polymerized sodium acrylate (PNaAA)/EPDM were investigated.The results showed that the water-swelling property of vulcanizate decreased as the additional level of DCP increased;the water-swelling property improved as the theoretical yield of PNaAA increased;the water swelling property of vulcanizate was better when the mole ratio of sodium hydroxide/AA was 1~1.2;the higher temperature of water solution,the greater water swelling ratio of vulcanizate;and the higher Na~+ content in water solution,the lower water swelling ratio of vulcanizate. |
