Anticorrosive water-based acrylic polyurethane finish paint and preparation process thereof

Abstract

The invention discloses an anticorrosive water-based acrylic polyurethane finish paint and a preparation process thereof, wherein the anticorrosive water-based acrylic polyurethane finish paint comprises acrylic polyurethane resin, toluene diisocynate, homoarginine, methyl isobutyl ketone, triethylamine, a film-forming auxiliary agent, a thickening agent, an organic metal catalyst and deionized water. During the preparation of the paint, by changing the content of toluene diisocynate and homoarginine, the performance of the finish paint is controlled; by changing the content of toluene diisocynate, reducing the surface tension of the finish paint and matching with the effect of the thickening agent, after the finish paint is brushed, the flowability is reduced, and the finish paint can be firmly attached to a brushed surface; and by changing the content of homoarginine, homoarginine reacts with carbon dioxide in the air to generate homoarginine salt in the drying process of the finish paint, so that a layer of special protective film is formed in the finish paint, the protective film cannot be oxidized in the air, the outside can be effectively isolated, the protective performance is improved, and the flowability of the finish paint is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion finish paint, in particular to an anti-corrosion water-based acrylic polyurethane top paint and a preparation process thereof. Background technique [0002] The top paint is the wall paint, which is often called latex paint. It is one of the main decorative materials used for the wall in home decoration. The wall paint accounts for a considerable proportion of the basic decoration cost. Choose high-quality wall paint It is very heavy. In order to achieve the purpose of bonding, the main component of wall paint is resin, which can be firmly bonded to the wall. According to different application areas, wall paint can be divided into interior wall latex paint and exterior wall paint. There are two categories of latex paint. In addition to their commonality, these two wall paints also have their own unique characteristics. Among them, interior wall latex paint is applied indoors, so its environ...

AI Technical Summary

Problems solved by technology

[0004] 1. The surface tension of the paint emulsion is relatively high. When it is painted on a vertical surface or an inclined surface, the paint tends to flow downwards, resulting in incomplete painting of the painted surface;

[0005] 2. After the paint is painted and dried, it is easy to oxidize in the air, which will lead to the fading of the paint and reduce the protective ability of the paint
