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 MH-ML 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.
