Епоксидно-акрилове антикорозійне покриття на водній основі є різновидом багатофункціонального покриття, захист навколишнього середовища та гарне покриття, which is widely used in different fields. This paper will introduce the preparation method of this coating in detail, as well as its outstanding performance in many application fields such as can wall, household appliances, інструменти, тощо.

Preparation method
The preparation process of waterborne epoxy-acrylic anticorrosive coatings involves the following key steps:

Synthesis of epoxy-acrylic resin

Перший, epoxy-acrylic resin with rich acid groups was formed by grafting epoxy resin with acrylic monomer or acrylic polymer. The resin is then neutralized with ammonia to form a corresponding salt.

Preparation of water emulsion

A mixture of epoxy resin, ethylene glycol monobutyl ether and n-butanol was added to the reaction vessel and stirred at a temperature of 110°C. A mixture of methacrylate, стирол, butyl acrylate and benzoyl peroxide (BPO) is slowly added over 3 години, and then heated to 120°C for 4 години. Subsequently, the temperature was lowered to 85°C, and a mixture of N, n-dimethylaminoethanol and distilled water was added, stirred at high speed and incubated at 50°C for 3 hours to finally obtain an epoxy-acrylic resin water emulsion.

Підготовка покриття

The epoxy-acrylic resin water emulsion is mixed with other raw materials and then mixed and ground through a sander until the desired fineness is reached. Нарешті, the epoxy-acrylic resin water emulsion is added to the mixture and thoroughly mixed.

Сфера застосування
Waterborne epoxy-acrylic anticorrosive coatings are known for their good performance and versatile properties, and the following are its main applications in different fields:

Can lining coating

This paint is widely used in canning production because it has excellent adhesion and is able to protect the inner wall of food cans from corrosion and contamination.

Household appliance

Waterborne epoxy-acrylic anticorrosive coatings are widely used in the home appliance industry, and can be used for the surface protection of refrigerators, washing machines and other equipment, with excellent impact resistance and wear resistance.

інструмент

This type of coating is also commonly used on the surface of various instruments and equipment, providing high strength, chemical resistance, corrosion resistance and good appearance.

Waterborne epoxy-acrylic anticorrosive coatings have become a pearl in the coatings market through careful preparation methods and superior properties in multiple application fields. Its excellent adhesion, стійкість до ударів, зносостійкість, weather resistance, corrosion resistance and environmental adaptability have made it widely favored in many industries. In the future, with the continuous pursuit of paint performance and sustainability, water-based epoxy-acrylic anti-corrosion coatings will continue to provide high-performance protection and beautification solutions for a variety of applications.
