摘　　要： 采用芳纶浆粕预处理方法专利技术对芳纶浆粕超细短纤维表面进行改性处理,制备在橡胶基质中纤维分散性良好的芳纶浆粕预分散体。通过对未处理芳纶浆粕和芳纶浆粕预分散体补强CR复合材料宏观性能和微观结构形态关系的对比研究,证实该专利技术的可行性,同时探讨了纤维状硅酸盐作为填料对芳纶浆粕纤维和芳纶短纤维补强CR复合材料物理性能的影响。 Art aramid pulp（AP） predispersion with short fibre well-dispersed in rubber matrix was prepared by modifying the surface of the AP superfine short fibre with the proprietary AP pretreating technology. The feasibility of the proprietary technology was confirmed by comparing the relationship between macro-properties and micro-morphology of untreated AP/CR composite to that of AP predispersion/CR composite, and the influence of the fibrous silicate filler on the physical properties of AP or DCAF/CR composites was also investigated.
