Acrylic emulsion with strong adhesive force for printing ink and preparation method of acrylic emulsion

The invention discloses a high-adhesion acrylic emulsion for ink and a preparation method of the acrylic emulsion. The acrylic emulsion comprises acrylic solid resin, a pre-emulsion, a pH regulator, an initiator, an emulsifier, an oxidant, rongalite, a defoaming agent and the balance of water. The pre-emulsion is a pre-emulsion A or a pre-emulsion B; the invention relates to the technical field of acrylic emulsion preparation. According to the high-adhesion acrylic emulsion for the printing ink and the preparation method of the high-adhesion acrylic emulsion, the lauryl sodium sulfate and the alkylphenol polyoxyethylene ether are used as emulsifiers, and the ratio of the lauryl sodium sulfate and the alkylphenol polyoxyethylene ether is regulated, so that the viscosity of the acrylic emulsion is effectively improved, the adhesion of the acrylic emulsion is improved, and meanwhile, the stability, the water resistance and the friction resistance of the emulsion are also greatly improved; the glossiness is impro
