The invention provides graphene-doped latex and a preparation method for the same, and particularly discloses a preparation method for graphene-doped latex. The preparation method comprises the following steps of dissolving crude rubber, dispersing the graphene, preparing a crosslinking system solution, and performing emulsification, crosslinking curing, solvent removal and concentration. According to the method, the graphene-doped latex is prepared by homogenizing the crude rubber, the graphene and a crosslinking agent with the same solution, performing blending emulsification, performing accelerated stirring to volatilize a solvent after curing and further adding a stabilizing agent for concentration and drying. The preparation method is less in influence on the environment and a human body, and graphene is uniformly distributed; the solid content of the graphene-doped latex is 28 to 31 percent, the particle size distribution of latex particles is uniform, the mechanical stability is high, and the latex is convenient to store and transport.
