The invention relates to a solution polymerized styrene-butadiene rubber which is prepared from styrene, butadiene, a hexamethylene-hexane mixed solvent, butyl lithium and natural rubber. The preparation method of the solution polymerized styrene-butadiene rubber comprises the following steps: carrying out high-purity nitrogen replacement on a reactor to remove oxygen, adding the hexamethylene-hexane mixed solvent, adding the butyl lithium, heating to initiation temperature, adding styrene-butadiene mixed monomers, carrying out polymerization to obtain a polymerization colloidal liquid, carrying out sample analysis to determine the relative molecular weight and distribution of the copolymer, discharging the colloidal liquid when the relative molecular weight reaches a designated value, adding the antioxidant, adding the aromatic oil at 30-40 DEG C, evenly mixing, condensing vapor, drying and dehydrating. The solution polymerized styrene-butadiene rubber has the characteristics of high crosslinking density, high tensile strength, favorable adhesion property, favorable heat resistance, favorable aging resistance, favorable abrasion resistance and the like, and thus, is a good raw material for tires and other products.
