The invention discloses a preparation method of styrene butadiene rubber liquid slurry added with white carbon black and a product prepared by using the same and relates to the technical field of performance improvement of high polymer composite materials such as rubber and the like. The slurry contains styrene butadiene latex and the white carbon black, wherein the mass ratio of the white carbon black to the styrene butadiene latex is 1-100%. The preparation method comprises the following steps: firstly, commonly stirring and premixing the white carbon black with water; then high shearing, dispersing and homogenizing the white carbon black water slurry to obtain a white carbon black-water suspension; subsequently, carrying out surface treatment on the white carbon black so that the surface of the white carbon black is organized; regulating the pH value of the suspension to 9-12; and finally, evenly mixing the suspension with the styrene butadiene latex to obtain the styrene butadiene latex liquid slurry adde
