| 运用乳液共沉法制备淀粉/NBR复合物，通过氢氧化钠和丙烯酸的中和反应，在NBR中原位合成丙烯酸钠(NaAA)，制备淀粉/NaAA/NBR复合材料，并对复合材料物理性能和吸水性能进行研究。结果表明，与直接添加NaAA的淀粉/NaAA/NBR复合材料相比，原位合成NaAA的淀粉/NaAA/NBR复合材料物理性能较好，吸水性能较差；随着浸水时间延长和浸水温度升高，直接添加NaAA的淀粉/NaAA/NBR复合材料吸水体积膨胀率增大，原位合成NaAA的淀粉/NaAA/NBR复合材料吸水体积膨胀率先增大后减小，前者吸水性能较好。 |
| 英文摘要: |
| Starch/NBR composite was prepared by emulsion co-coagulation method.Through neutralization reaction of sodium hydroxide and acrylic，sodium acrylate(NaAA) was prepared in situ in NBR compound，then starch/NaAA/NBR composites were prepared，and the physical properties and water-absorbent property were investigated.The results showed that，the physical properties of starch/NaAA/NBR composite through in situ formation of NaAA was better，but the water absorbent property was worse compared with starch/NaAA/NBR composite by adding NaAA directly；the volume welling ratio of starch/NaAA/NBR composite by adding NaAA directly was always increased，the starch/NaAA/NBR composite through in situ formation of NaAA
was increased first and then decreased as the time of soaking extended and the temperature rose，and the water-absorbent property of the former was better. |
