| 摘 要： | 将丁腈橡胶与高吸水树脂（SAP）、增强剂、聚乙二醇（PEG）和二苯基甲烷二异氰酸酯（MDI）等在开炼机上充分混合,在高温下PEG和MDI发生逐步聚合反应,与丁腈橡胶原位互穿,得到互穿网络型吸水膨胀橡胶（IPN-SWR）。研究了聚氨酯（PU）用量对互穿网络型吸水膨胀橡胶的机械性能和吸水膨胀性能的影响。结果表明,随着PU含量升高,橡胶的机械性能下降,吸水速率加快,最大质量膨胀倍率（ΔWe）先升高后降低,质量损失率降低,循环测试次数越高,膨胀性能下降,质量损失率变小。同种材料的胶筒制品的膨胀速率远远小于试片的膨胀速率。

| Abstract: | The nitrile rubber,super absorbent polymer(SAP),reinforcing filler,polyethylene glycol(PEG) and diphenylmethane diisocyanate(MDI)were mixed by two-roll mill machine.Step polymerization reactions between PEG and MDI,which in-situ interpenetrating with nitrile rubber molecule,occurred at high temperature and the IPN-based water swelling rubber(IPN-SWR) was obtained.The influences of the dosage of polyurethane(PU) on mechanical properties and water absorption expansion properties of IPN-based water-swelling ru... |
