The styrene acrylic emulsion coating has the dominant advantage in the water based coating of paper products. It has good weatherability, strong adhesion and good leveling. In the process of emulsion polymerization, the diameter of latex particles is one of the most important indexes for the quality of the emulsion, and the water absorption of the emulsion film is an important symbol of the performance of the emulsion. The smaller the particle diameter and the narrower the distribution of the latex particles, the lower the surface tension of the emulsion and the better the film leveling is, and it also has better permeability and wettability to the substrate and stronger adhesion.

The lower the water absorption of the emulsion coating, the stronger the water resistance of the coated products. Many factors affect the particle diameter and water absorption rate, such as : type, amount and ratio of emulsifier, initiator amount, acid and alkaline monomer influence, solid content, the seed emulsion monomer ratio and other factors, all these factors will have a significant impact on the particle diameter and water absorption of film. At the same time, the above factors are related to each other. The understanding of these factors has an important guiding role in the study and mastery of emulsion polymerization technology. In this study, the above factors are carried out one by one, and some regular results are obtained in a certain range.
