一种聚(衣康酸酯/异戊二烯)生物基弹性体/层状硅酸盐纳米复合材料制备方法
摘要：
本发明涉及一种聚(衣康酸酯/异戊二烯)生物基弹性体/层状硅酸盐纳米复合材料制备方法。为一种来源于可再生生物质资源的康戊胶与层状硅酸盐湿法复合后再经过化学交联而成。层状硅酸盐/康戊胶纳米复合材料是一种新型的环境友好型的复合材料，填充层状硅酸盐还能降低橡胶的成本，是一种很有前景的气密型绿色橡胶制品。本发明制备的材料具有环境友好性和气体阻隔性能，所述的康戊胶/层状硅酸盐纳米复合材料的气体透过系数为1.7～10.4×10-17m2s-1Pa-1。为提高强度，还可添加20～50质量份的白炭黑（SiO2）或炭黑等联合增强剂。
摘要（英）：

The invention relates to a poly(itaconate/isoprene)bio-based elastomer/layered silicate nanocomposite material preparation method. A poly(itaconate/isoprene)bio-based elastomer/layered silicate nanocomposite material is obtained through wet compounding of a poly(itaconate/isoprene)bio-based elastomer and layered silicate, and chemical cross-linking. The layered silicate/poly(itaconate/isoprene)bio-based elastomer nanocomposite material is a novel environmentally-friendly composite material, and the filling of layered silicate can reduce the rubber cost, so the composite material is an airtight green rubber product having a very good prospect. The material prepared in the invention has an environmental protection property and a gas barrier performance, and the gas permeation coefficient of the poly(itaconate/isoprene)bio-based elastomer/layered silicate nanocomposite material is 1.7-10.4*10<-17>m<2>s<-1>Pa<-1>. 20-50 parts by mass of combined reinforcing agents comprising white carbon black (SiO2) or carbon black, and the like can be added to improve the strength of the composite material.
