| Abstract: |
| The research situation of the functionalization 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 solution-polymerized styrene-butadiene rubber（SBR），long-chain branched rare earth cis-butadiene rubber（BR） and high vinyl content BR.The main functional formulation technologies of rubber materials are binary and ternary combination of NR，SBR and BR，preparation of co-precipitated rubber/silica compound， formulation technologies of silica with coupling agents and processing aids，and application of flake inorganic fillers in the inner-liner compound. Recent advances in functional research of rubber material are mainly development of high toughness compounds，adaptive composites, air-tight composites，and compatibility of material systems.Besides the functional property，other properties of the functional rubber material for green tire have to meet the application requirements. |
