Grinding and binder integrated acrylic emulsion as well as preparation method and application thereof

The invention discloses a grinding and binder integrated acrylic emulsion and a preparation method and application thereof, and the acrylic emulsion is prepared from the following raw materials by weight: 3-5 parts of an unsaturated hydroxyl functional monomer, 5-8 parts of an unsaturated dibasic acid monomer, 8-15 parts of an acrylate hard monomer, 20-30 parts of an acrylate soft monomer, 0.1-0.5 part of a chain transfer agent, and 0.5-1.5 parts of an initiator. 1-5 parts of an emulsifier and 45-55 parts of water. The acrylic emulsion provided by the invention has a core-shell structure, and by adding a specific content of unsaturated dibasic acid monomer and unsaturated hydroxyl functional monomer into the shell structure, pigment grinding and high adhesive force to a film substrate can be realized, and the special performance of ink drying speed can be improved by diluting with ethanol in any proportion; the core structure, as a binder moiety, provides associated resistances. Due to the unique excellent pe
