研究硫化体系、硫化条件和白云母用量对天然橡胶/丁苯橡胶/白云母复合材料性能的影响。结果表明：复合材料优化硫化体系为促进剂D 1，促进剂CZ 0.6，促进剂DM 0.6，硫黄2.5；适宜的硫化条件为145℃×8 min；当改性白云母用量为20，40和60份时，复合材料的物理性能和耐磨性能满足工业车辆轮胎胎面胶和垫带胶、农业轮胎胎面胶和垫带胶、载重型和非载重型力车轮胎胎面胶以及鞋跟胶料国家或行业标准要求；改性白云母用量为20份时，复合材料的物理性能和耐磨性能可以满足大部分橡胶制品的要求。%In this study,the effects of curing system,curing conditions and the amount of muscovite on the properties of NR/SBR/Muscovite composites were investigated.The optimized curing system was as follows:accelerator D1,accelerator CZ0.6,accelerator DM0.6,and sulfur2.5.The optimum curing condition was 145℃×8 min.When the amount of modified muscovite was 20,40 or 60 phr,the physical properties and wear resistance of the composite met the requirements of national standards or industry standards on various rubber products: tread and flat of industrial tire and agricultural tire,tread of load and non-load cycle tire,and shoe heel compound.When the amount of modified muscovite was 20 phr,the physical properties and wear resistance of the composite met the specifications of most rubber products.
