摘要

采用一种新型制备方法——预膨胀有机黏土与机械共混的方法制备丁基橡胶（IIR）/有机黏土纳米复合材料。实验结果表明，当有机黏土为10 phr时，采用预膨胀有机黏土（S-OC）与机械共混的方法制备的IIR/有机黏土纳米复合材料（IIR/S-OCNs）的拉伸强度和撕裂强度，明显优于采用熔体法制备的IIR/有机黏土（OC）纳米复合材料（IIR/OCNs）的相应性能，较纯丁基橡胶分别提高了4.96倍、0.22倍；当有机黏土为5 phr时，采用预膨胀有机黏土与机械共混的方法制备的IIR/S-OC纳米复合材料的气体渗透率，分别较纯IIR、熔体法制备的IIR/OC纳米复合材料下降了21.88%和12.50%。这种新型制备方法是将溶液制备方法的优点与熔体制备方法的优点有机地统一在了一起。该材料有可能在高级无内胎轮胎气密层以及其他要求高性能弹性体材料的领域获得应用。

Abstract

Isobutylene-isoprene rubber(IIR)/clay nanocomposite was synthesized by shearing mixing of pre-swollen orgnomontmorillonite (S-OC)with IIR.The experimental results demonstrated that the properties of the as-prepared nanocomposite (IIR/S-OCNs)were superior to those of nanocomposite prepared with the traditional melt intercalation method (IIR/OCNs).When the loading of clay was 10 phr

tensile strength and tear strength were about 4.96 and 0.22 times higher than those of pure IIR. When the loading of clay was 5 phr

gas permeability of the IIR/S-OCNs was reduced markedly by 21.88% and 12.50% compared to pure IIR and IIR/OCNs.The novel strategy united the advantages of melt method and solution method together.The IIR/clay prepared by the novel method could be applied in rubber products

which required high gas barrier property

such as tire inner tube

inner liner and applied in other elastomer materials.
