Problems solved by technology

Although water-based coatings have certain advantages in terms of construction, storage, and cost, there is still a big gap in water resistance, chemical resistance, and weather resistance of the paint film, which cannot meet the requirements of more demanding applications.
[0004] In addition, with the implementation of the concept of green environmental protection, the traditional paint and spraying process is being abandoned by people. However, after using the existing process to spray water-based paint, the surface gloss of the furniture is poor, and the brightness is not good, which affects the appearance.

Abstract

The invention relates to rare-earth colorful anticorrosive water-based paint and a preparation method thereof. The rare-earth colorful anticorrosive water-based paint, made from polystyrene-acrylic resin, water-based polyurethane, silane coupling agents, surfactants, water, a rare earth colorant solution system, wetting agents, fillers, defoamers, dispersants, antioxidants and UV absorbers in an appropriate weight ratio, are non-toxic and harmless; no organic solvent is volatilized during storage and use, and environmental protection is achieved; the rare-earth colorful anticorrosive water-based paint has high resistance to acid, alkali, corrosion, water and aging, strong color fastness and high adhesion; paint layers formed after coating have high toughness, gloss and adhesion and do notcontain residual toxic and harmful small molecular substances and toxic heavy metals to achieve high safety; the coating speed of the paint and the production efficiency are high, the coating amount per unit area is small, the energy consumption is low, and the cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a rare-earth colorful anti-corrosion water-based coating and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of industry, the problem of environmental pollution has attracted more and more attention. Countries around the world are taking strict measures to limit the emission of volatile organic compounds. Green materials have become the mainstream in the field of material research and application. In order to adapt to this trend, water-based coatings have emerged as the times require and have become an extremely active research and development field. Water-based coatings are one of the best ways to reduce VOC. [0003] Water-based coatings are widely used in coatings, adhesives and other industries due to their environmental friendliness. Although water-based coatings have certain advantages in terms of construction, stora...
