摘　　要：无机矿物填料对橡胶复合材料的性能具有重要影响,主要研究了包括微晶石墨(GM6)、微型硅酸盐(MS-1)、粉煤灰(FA)和砖粉(BP)等无机矿物填料对天然橡胶(NR)复合材料的硫化特性和力学性能的影响。结果表明,当微晶石墨(GM6)被用作填料时,橡胶复合材料表现出最高的最高转矩与最低转矩的差值(M_(H)-M_(L))值和最快的硫化时间。此外,该复合材料在拉伸强度、撕裂强度、硬度和耐磨性方面均表现出最佳性能,而断裂伸长率没有明显的差异。该研究发现为无机矿物材料在橡胶中的应用和优化提供了参考。Inorganic mineral fillers have an important influence on the properties of rubber composites,and the effects of inorganic mineral fillers including microcrystalline graphite(GM6),microsilicates(MS-1),fly ash(FA),and brick powder(BP)on the vulcanisation characteristics and mechanical properties of natural rubber(NR)composites were mainly investigated.The results showed that the rubber composites exhibited the highest M_(H)-M_(L)values and the fastest vulcanisation time when microcrystalline graphite(GM6)was used as a filler.In addition,the composites exhibited the best performance in terms of tensile strength,tear strength,hardness and abrasion resistance,with no significant difference between the composites in terms of elongation at break.The findings provide a reference for the application and optimisation of inorganic mineral materials in rubber.
