Abstract

The invention relates to a preparation method of high-performance acrylic resin. According to the method, water, sodium dodecyl benzene sulfonate, fatty alcohol-polyoxyethylene ether and 2-acrylamide-2-methylpropanesulfonic acid are added; the temperature is raised; stirring is performed; monomers A are added; the emulsification is performed for 40min; when the temperature is raised to 70 DEG C, backflow water is introduced; when the temperature is raised to 85 DEG C, a potassium sulphate solution is added; the reaction is performed for 2h; then, fluticasone propionate is added; stirring and reaction are performed to obtain core layer emulsion; monomers B and a potassium peroxodisulfate solution are simultaneously dripped into the core layer emulsion; after the dripping is completed, stirring and reaction are performed; the temperature is lowered to 50 DEG C; the fatty alcohol-polyoxyethylene ether and the fatty alcohol-polyoxyethylene ether are added; the reaction time is 70 minutes; the reaction is performed for 1h at 70 DEG C; ammonia water is added for regulating the pH value to 7 to 8 to obtain the acrylic resin. The preparation method has the advantages that the abrasive resistance of the acrylic resin is greatly improved; the defect that a film formed by the acrylic resin emulsion becomes yellow is overcome.
