Waterborne drawing paint and preparation method thereof

Abstract

The invention discloses waterborne drawing paint and a preparation method thereof. The waterborne drawing paint is prepared from, by weight, 40-45% of tinting pigment paste, 15-20% of acrylic resin, 15-20% of talcum powder, 1-2% of waterborne butyl ether amino resin, 1-2% of epoxy phosphate resin, 2-3% of butyl ether, 2-3% of waterborne zinc stearate, 0.1-0.2% of defoamer, 0.2-0.4% of dispersant,0.5-1% of wetting agent, 0.2-0.3% of flatting agent, 3-5% of neutralizing agent, 0.5-0.7% of thickener and the balance deionized water. With the help of cooperative use of various assistants, pigmentsare wet and dispersed, pigment particles have good stability and compatibility, and the overall performance of the paint is greatly improved; the obtained product has the characteristic of being morestable, the surface tension and the wettability of the paint are better than those of waterborne paint, the characteristics of being good in weather fastness, aging resistance and adhesive force areachieved, and harm and pollution caused by organic solvent volatilization in the production and application processes are further greatly reduced.

Description

technical field [0001] The invention relates to the field of water-based paint, in particular to a water-based wire-drawn paint that can be used for coating and metal surface wire-drawing process and a preparation method. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection awareness, people's environmental protection requirements for decorative materials are also getting higher and higher. Ordinary solvent-based paints contain a large amount of organic solvents, which cause great pollution to the environment. After use, they will cause harm to the human body. The amount of coating and metal surface treatment has been continuously reduced, and many environmentally friendly paints for different purposes have been developed. . Water-based paint is one of them. It uses water as a diluent, does not contain benzene, toluene, xylene, formaldehyde, and free TDI toxic heavy metals. It is non-toxic, non-irrit...

Problems solved by technology

[0005] In a further solution created by the present invention, the acrylic resin is a water-based thermosetting acrylic resin, which is the main film-forming substance and provides a high-hardness paint film, which can improve the water-resistant and anti-aging capabilities of the water-based brushed paint, and the drying speed is fast and the time is short. It solves the problem that the drying speed is slow and cannot be used in low temperature weather; the colored pigment slurry is an organic pigment of phthalocyanine or condensed azo, which is the main film-forming substance and mainly plays a coloring role
