Abstract

The invention discloses waterborne acrylic modified epoxy ester resin as well as a preparation method and application thereof, belongs to the field of chemical engineering, and solves the problem that the corrosion resistance of existing hydrophilic resin is reduced. The resin comprises epoxy ester resin, epoxy phosphate, styrene, methyl methacrylate, butyl acrylate, acrylic acid, benzoyl peroxide, tert-butyl hydroperoxide, ethylene glycol monobutyl ether, dimethylethanolamine and deionized water. The preparation method comprises the following steps: heating the epoxy ester resin and the epoxy phosphate; dropwise adding a mixed solution of the styrene, methyl methacrylate, butyl acrylate, acrylic acid and benzoyl peroxide; adding the tert-butyl hydroperoxide; cooling and vacuumizing; adding the dimethylethanolamine for a neutralization reaction, and adding the deionized water for emulsification and dispersion. The waterborne acrylic modified epoxy ester resin is applied to water-based industrial anticorrosive paint. The water-based anticorrosive paint prepared from the waterborne acrylic modified epoxy ester resin has the characteristics of quick drying and high weather resistance of acrylic resin, and also has the characteristics of high adhesive force, high corrosion resistance and the like of epoxy resin.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a water-based acrylic modified epoxy ester resin and a preparation method thereof. Background technique [0002] Coatings are polymer functional material products that provide supporting protection and surface decoration for many industries in the national economy. Among them, water-based industrial coatings are emerging new environmentally friendly coating products, which belong to the category of new materials for national strategic emerging industries. In 2019, my country's paint production has reached 24.388 million tons, making it the world's largest paint production and consumption country. However, in stark contrast to the rapid development of output, the share of domestic environmental protection coatings is very low, especially the market share of water-based industrial coatings is very low due to the constraints of key technologies and backward key material ...
