【摘要】 以硅烷为改性剂 ,利用高速混合搅拌机对湖北宜昌煤系煅烧高岭土进行表面改性处理 ,然后将其填加到丁苯橡胶中进行应用试验 ,通过充填橡胶的硬度、伸长率、扯断强度、撕断强度以及永久变形等机械性能的测定 ,表明煅烧高岭土完全可用于丁苯橡胶做补强剂更多还原

【Abstract】 Calcined coal-measures kaolin is modified with silane as a modifying agent,and the optimal technological conditions are found in this research. When the modified calcined coal-measures kaolin is added to SBR,the mechanical performances of the filled SBR,such as hardness,elongation rate,tensile strength and permanent set can fulfil quality requirements as an intensifier of SBR.更多还原
