利用独创的粘土晶层／胶乳纳米互穿技术获得了粘土／ＮＢＲ纳米复合材料。通过Ｘ光衍射、透射电子显微镜证实和分析了其纳米分散相结构。物理性能的研究结果表明，当粘土用量较小时，复合材料的拉伸强度便达到了一个较高的水平，且远高于炭黑Ｎ３３０补强胶料的水平。复合材料的定伸应力随粘土用量的增大而直线上升，耐磨性迅速提高。当粘土用量达到２０份时，复合材料的气密性优于用ＣＩＲ制造的无内胎子午线轮胎气密层胶料。
Clay / NBR nanocomposites were obtained using the original clay crystal / latex nanocomposite technology. The structure of nanodispersed phase was confirmed and analyzed by X-ray diffraction and transmission electron microscopy. The results of physical properties show that when the amount of clay is small, the tensile strength of the composite reaches a higher level, which is much higher than that of the carbon black N330 reinforcing compound. The tensile stress of composite material increases linearly with the increase of clay content, and the wear resistance increases rapidly. When the clay content reaches 20 parts, the airtightness of the composite is better than that of a tubeless radial tire inner liner made by CIR.
