The invention discloses a surface grafted poly-conjugated diene modified silicon dioxide composite material and a preparation method thereof. The surface-grafted poly-conjugated diene modified silicon dioxide composite material is obtained by vulcanizing silicon dioxide of which the surface is grafted with poly-conjugated diene. The preparation method of the silicon dioxide with the poly (conjugated diene) grafted on the surface comprises the following steps: uniformly mixing an initiator, a ligand, a metal catalyst, a conjugated diene monomer and a solvent, optionally adding a reducing agent, and carrying out atom transfer radical polymerization. The surface grafted poly conjugated diene modified silicon dioxide composite material is a nano composite material with low heat generation, low rolling resistance and excellent low-temperature performance.

    本发明公开了一种表面接枝聚共轭二烯改性二氧化硅复合材料及其制备方法。所述表面接枝聚共轭二烯改性二氧化硅复合材料由表面接枝聚共轭二烯烃的二氧化硅硫化得到。所述表面接枝聚共轭二烯烃的二氧化硅的制备方法包括将引发剂、配体、金属催化剂、共轭二烯单体和溶剂混合均匀,任选地加入还原剂,进行原子转移自由基聚合。所述表面接枝聚共轭二烯改性二氧化硅复合材料是一种低生热、低滚阻、低温性能优异的纳米复合材料。
