绿色轮胎用橡胶材料功能化的研究概况

介绍绿色轮胎用橡胶材料功能化的研究概况。绿色轮胎用橡胶的功能化研究目前集中于湿法混炼天然橡胶（NR）/白炭黑母炼胶、石墨烯或碳纳米管补强NR、高强度NR、多官能化溶聚丁苯橡胶（SBR）、长链支化稀土顺丁橡胶（BR）以及高乙烯基BR等材料；橡胶材料的功能化配合技术主要是NR，SBR和BR的二元和三元并用、橡胶/白炭黑共沉胶制备、白炭黑与偶联剂和加工助剂的配合以及片状无机填料在气密层胶中的应用；橡胶材料功能化研究新进展主要为高韧性胶料、自适应性复合材料和气密性复合材料的研发以及材料体系相容性的研究。绿色轮胎用橡胶材料在实现功能化的同时，要保证胶料的综合性能。;The research situation of the functionlization of rubber material for green tire is introduced.The functionalization of rubber for green tire is currently focused on wet mixing of natural rubber（NR）/silica master rubber，graphene or carbon nanotube reinforced NR，high strength NR，multi-functional soluble styrene-butadiene rubber（SBR），long-chain branched rare earth cis-butadiene rubber（BR） and high vinyl content BR and other materials.The main functional matching technologies of rubber materials are binary and ternary combination of NR，SBR and BR，the preparation of rubber/silica coprecipitate，the matching of silica with coupling agents and processing aids，and the application of flake inorganic fillers in innerliner compound.Recent advances in functional research of rubber material are mainly development of high toughness compounds，adaptive composites and air-tight composites，and compatibility of material system.When the functionalization of rubber material for green tire is realized，the comprehensive properties of rubber compound should be guaranteed
