Q2Study on the mechanism of silica sol coupling modified styrene acrylic emulsion

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。

Q2The influence factors of benzene - propylene emulsion granule diameter and film absorption rate

In the paper products with water - based paint, the absolute advantage is the benzene - acrylic emulsion coating, its weatherability is good, the adhesion strong, the level is good.In the process of emulsion polymerization, the diameter of the emulsion is one of the important indexes of emulsion synthesis quality, and the water absorption rate of emulsion coating is an important symbol of the emulsion performance.The smaller the diameter of the emulsion, the narrower the distribution, the lower the surface tension of the emulsion, the better the film flow flattening, the better permeability and wettability of the bottom material, and the stronger the adhesion.


The lower the absorption rate of the emulsion coating, the stronger the product is.Influencing colloidal particle diameter and water absorption of many factors, such as: the varieties and amount of the emulsifier and the proportion, dosage of initiator, acid monomer, the effects of solid content, factors such as monomer ratio of seed emulsion, bibulous rate of colloidal particle diameter and film have obvious impact.At the same time these factors are interrelated.To understand these factors, it is important to study and master the emulsion polymerization technique.In this study, the influence factors were investigated and some regularity results were obtained.
