Effect of Reactivee Mulsifier on Properties of Acrylate Microemulsion

The polymerizable surfactant will form a covalent bond with the monomer in the reaction system, and will not migrate during the film-forming process. This will help to improve the water resistance and the stability of the emulsion. In this paper, an acrylate microemulsion with an average particle size of 55 nm and solid content of 40% was synthesized by non-pre-emulsion polymerization. The reactive surfactant NR-1 on the properties of acrylate emulsion was systematically studied. The emulsion resistance was increased, the stability was increased, and the shear resistance of the emulsion was enhanced effectively with the increase of the amount of reactive emulsifier NR-1. It was found that when the amount of NR-1 was 1%, the emulsion had the best comprehensive properties.
