The invention discloses a cationic polymer emulsion for dip dyeing of a coating. The polymer emulsion is synthesized by adopting an emulsion polymerization method by taking styrene and butyl acrylate as a monomer, hexadecyltrimethyl ammonium chloride as a cationic emulsifier and azobis methylpropion amidine dihydrochloride as a cationic initiator. Emulsion particles in the polymer emulsion have positive charges and can be combined with coating particles and fibers with negative charges, so that the emulsion particles can be fixedly attached on the surfaces of the fibers. According to the cationic polymer emulsion applied to dip dyeing of the coating, the color depth, the fastness and the hand feel are improved.
