Water-based amino industrial coating and preparation method thereof

Abstract

The invention discloses a waterborne amino industrial paint. The waterborne amino industrial paint comprises the following raw materials by weight: 35-55 parts of a modified hydroxyl acrylic emulsion,1.5-2 parts of carbon black, 1-2 parts of zinc aluminum phosphomolybdate, 1.5-3 parts of a liquid antirust pigment, 1-2 parts of amino resin, 35-45 parts of water, 1-2 parts of a dispersant, 1-2 parts of a defoamer and 1-2 parts of a leveling agent. The paint prepared by the method provided by the invention has the advantages of high hardness, good flexibility, excellent adhesion to different substrates, excellent interlayer adhesion when matching with a primer, and good decorativeness and chemical resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based amino industrial coating. Background technique [0002] my country is a major producer and exporter of light industry (household appliances, bicycles, motorcycles, sewing machines, etc.), machinery parts industry, transformer industry, agricultural machinery, and packaging barrels (cans) and other industries. The metal anti-corrosion and decorative protection of the above products are mainly effectively protected by solvent-based amino baking varnish. Because of its convenient construction, amino baking varnish not only has excellent mechanical properties (fast drying, high hardness, short construction period, and can be used off-line), but also has excellent decorative properties (high gloss), and is widely used in areas closely related to people's livelihood. In the field, as we all know, solvent-based amino products contain a lot of xylene and butanol, and even...

AI Technical Summary

Problems solved by technology

The coating protection of products in these industries requires not only high decorativeness, but also excellent anti-corrosion performance. Traditional water-based coatings can only be used as low-grade anti-corrosion or simple decorative single-coat coatings, and VOC content is still common Higher, low coating hardness, poor water resistance and adhesion, low gloss, short coating protection life and other defects, cannot meet the requirements of high-end products

At the same time, the construction performance is poor, and it is difficult to apply to assembly line operations. Therefore, it is urgent to develop high-decorative and long-lasting anti-corrosion water-based amino industrial coatings to replace existing varieties to meet the needs of these industries, reduce the LCC cost of coating companies, and achieve my country's environmental protection and energy saving. row request
