The air tightness of the clay/ SBR nanocomposite prepared by mixing clay and SBR latex was investigated. The results showed that the air tightness of clay/ SBR nanocomposite was better than that of the traditional filler filled SBR vulcanizate, and changed fewer with the temperature; 对乳液法制备的SBR粘土纳米复合材料的气密性进行了研究,结果表明:SBR粘土纳米复合材料的气密性优于传统填料填充的硫化胶,且随温度的变化较小;
A modified kaolinite/ NR composite was prepared by coacervation-coprecipitation of concentrated NR latex with modified kaolinite and the influence of the preparation conditions on the mechanical properties of vulcanizate was investigated. Moreover, the tensile sectional morphology of vulcanizate was analyzed by SEM. 以浓缩NR胶乳为主体材料,改性高岭土为填料,用凝聚共沉法制备改性高岭土/NR复合材料,研究影响复合材料物理性能的因素,并对材料拉伸断裂面的形貌进行扫描电镜分析。
