Abstract：To enhance the flocking fastness and texture of the product,a polyacrylate electrostatic flocking adhesive was synthesized by introducing hydroxyethyl acrylate by semi-continuous seed emul-sion polymerization method.The effects of emulsifier proportion,emulsifier dosage,initiator dosage,polymerization temperature and other factors on the properties of emulsion were discussed,and the synthesis process was identified as follows:The ratio of alkylphenol ethoxylates to sodium lauryl sul-fate is 1∶1,emulsifier dosage was 5％,initiator ammonium persulfate dosage was 0.5％,and the polymerization temperature was 80℃.The average particle size of the prepared polyacrylate emulsion was 129.7 nm,the monomer conversion rate was as high as 97.23％,and the gel rate was 1.14％.The effects of the dosage of functional monomer hydroxyethyl acrylate and the ratio of soft and hard monomers on the properties of emulsion and adhesive film were explored.The results showed that when the dosage of hydroxyethyl acrylate was 2％and the ratio of hard and soft monomers was 65∶15,the peeling strength of the adhesive film was 1.70 kN/m,and the film-forming property was good.The emulsion is used in electrostatic flocking,the flocking product has good fastness,wear re-sistance up to 9030 times,soft touch,softness of 87.74,smoothness of 74.14.
