Acrylate emulsion has the advantages of strong adhesion, simple production process, and low cost. It is the most common type of coating raw materials. It is generally an anionic emulsion, that is, an anionic group is used in the structure of the synthetic raw material, which mainly exists in the anion. Surfactant, anionic monomer initiator. In addition, there is also a type of cationic acrylate emulsion, which is characterized by the surface of the latex particles with a cationic structure or the emulsion itself with cations. Because most substrates have a negative charge on the surface, the cationic acrylate latex is between the substrate and the substrate. It has good adhesion and increases the adhesion of the film. Although there are not many related reports at present, it shows more excellent performance in some special applications.
