摘　　要：采用橡胶加工分析(RPA)仪、扫描电子显微镜(SEM)和透射电子显微镜(TEM)分析方法验证硫化仪数学分析方法评价无机填料在橡胶基体中分散状况和最佳填料用量的可行性。结果表明:RPA,SEM和TEM,以及硫化仪数学分析3种方法均得出N-苯基-N′-(γ-三乙氧基硅烷)-丙基-硫脲(STU)用量为0.92份时,STU/白炭黑/天然橡胶体系的最佳白炭黑用量为30份左右,证明将硫化仪数学分析方法用于橡胶复合材料配方设计时,可对填料分散状况和最佳用量做出正确评判。The feasibility of using rheometer and mathematic analysis method to evaluate the dispersion of filler in rubber matrix and achieve an optimum filler loading level were verified by RPA,SEM and TEM analysis.The results showed that the three methods of RPA,SEM and TEM,as well as rheometer and mathematic analysis method came to the same result that the optimum addition level of silica filler in STU/silica/NR compound with 0.92 phr STU was about 30 phr.It was suggested that the rheometer and mathematic analysis method could be effective for evaluating the dispersion of filler and optimum filler content in designing rubber composite.
