The invention discloses a method for adjusting a physical property through mixed using of emulsion polymerized styrene-butadiene latex, provides a technology for achieving adjustment of the physical property of rubber through a combination formula that different types of low temperature latex are utilized to polymerize styrene-butadiene latex, and belongs to the technical field of styrene-butadiene rubber production. The method is characterized in that physical property parameters of to-be-adjusted latex are adjusted in a mode that adjusting latex is mixed into the to-be-adjusted latex, specifically, the to-be adjusted latex and the adjusting latex are different in types, and the mixing proportional quantities of the to-be-adjusted latex and the adjusting latex are determined through a data formula that D*R is smaller than or equal to L; wherein D is the absolute value of a difference value of a target Mooney viscosity value of the to-be-adjusted latex and a Mooney viscosity value of the adjusting latex, R is the volume ratio of the adjusting latex and the to-be-adjusted latex, and L is larger than zero and smaller than five. In the production process of the low temperature emulsion polymerized styrene-butadiene rubber, adjustment of the physical property parameters is achieved through mixed using of the to-be-adjusted latex and the adjusting latex according to a set proportion.
