Problems solved by technology

The existing water-based paints on the market have the characteristics of difficulty in dispersion and poor storage stability, and corrosion often occurs during construction and application in winter
In addition, the current common metal water-based paints have poor hardness, the anti-corrosion and anti-rust functions cannot last long, and the weather resistance is poor. When the temperature is low in winter, they are easy to fall off and cannot achieve a better anti-rust effect.

Abstract

The invention relates to a metallic water-based paint and a preparation method thereof. The metallic water-based paint comprises the following components in percentage by weight: 35-40% of an acrylic emulsion, 2-3% of propylene glycol, 3-6% of rock powder, 0.1-0.4% of a wetting agent, 0.05-0.3% of a dispersant, 8-12% of a color paste, 0.1-0.4% of a defoaming agent, 0.1-0.4% of a neutralizing agent, 4-6% of a film coalescing aid, 0.1-0.3% of a leveling agent, 0.05-0.3% of a preservative, 3-5% of bentonite, 1-4% of a thickening agent, 0.2-0.5% of a coupling agent and 1-3% of acrylic resin. Compared with the prior art, the metallic water-based paint provided by the invention has the advantages of good weathering resistance, strong ageing resistance, strong adhesive power and capability of reducing product corrosion.

Description

technical field [0001] The invention relates to a water-based paint, in particular to an anti-corrosion and anti-rust metal water-based paint with good weather resistance. [0002] The present invention also relates to a preparation method of the above-mentioned metallic water-based paint. Background technique [0003] As an environmentally friendly and convenient metal paint, water-based metallic paint has been used more and more widely in recent years, and its cost is low. It has been more and more respected and developed rapidly. The existing water-based paints on the market have the characteristics of difficulty in dispersion and poor storage stability, and phenomena such as corrosion often occur during construction and application in winter. In addition, the current common metal water-based paints have poor hardness, the anti-corrosion and anti-rust functions cannot last, and the weather resistance is poor. When the temperature is low in winter, they are easy to fall o...
