The invention relates to a method for preparing a white carbon black/solution-polymerized styrene-butadiene rubber nano composite material. In the invention, nano white carbon black powder and silanecoupling agent are fully mixed and condensation reaction is carried out at high temperature, organic modified nano white carbon black powder is obtained and added into solution-polymerized styrene-butadiene; the mixture of the white carbon black powder and solution-polymerized styrene-butadiene is stirred and removes solvent and then dried, thus obtaining the silicon dioxide/solution-polymerized styrene-butadiene rubber nano composite material prepared by co-polymerization. The invention expands the range of methods for preparing the nano composite material with solution composition. The adopted method using the organically modified white carbon black is simple and easy for operation and the solution composite technique is fast and convenient with low cost. The prepared co-polymerized rubber can be taken as master
