O revestimento anticorrosivo epóxi-acrílico à base de água é um tipo de multifuncional, proteção ambiental e revestimento de bom desempenho, 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, electrodomésticos, instrumentos, etc..

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

Synthesis of epoxy-acrylic resin

Primeiro, 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, estireno, butyl acrylate and benzoyl peroxide (BPO) is slowly added over 3 horas, and then heated to 120°C for 4 horas. Subseqüentemente, 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.

Preparação de revestimento

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. Finalmente, the epoxy-acrylic resin water emulsion is added to the mixture and thoroughly mixed.
