Problems solved by technology

At present, there are many water-based antirust products on the market, but most of them are anti-corrosion through the addition of pigments and fillers, which cover the luster of the metal surface, and the antirust effect of varnishes without these fillers is very poor.

Abstract

The invention relates to water-based metal rust-proof varnish and a preparation method thereof, and belongs to the field of coating. The water-based metal rust-proof varnish comprises the following components in parts by weight: 5 to 15 parts of deionized water, 70 to 80 parts of water-based polymer emulsion, 1 to 2 parts of a salt-mist-resistant agent, 0.5 to 1 part of a corrosion inhibitor, 0.1 to 0.3 part of a wetting and leveling agent, 2 to 3 parts of wax emulsion, 4 to 6 parts of alcohol ester-12, 0.2 to 0.4 part of a pH regulator and 0.2 to 0.5 part of an associative thickener. The water-based metal rust-proof varnish can form a paint film quickly at room temperature, has high transparency, light color, high glossiness and good plumpness, is smooth and fine, and perfectly takes on the metal effect of a substrate. High-performance materials are selected, so that the paint film has strong ultraviolet-resistant ability, good adhesive force, high weather resistance, yellowing resistance, water tolerance, scraping resistance, high hardness and long rust-proof time, and is bright and clean as new after being washed by rain. The product is non-toxic and odorless, does not contain components which are harmful to a human body and the environment, and is real environment-friendly water-based corrosion-resistant coating. The water-based metal rust-proof varnish is convenient to construct and high in self-drying speed, improves the efficiency and reduces the energy.

Description

technical field [0001] The invention relates to a water-based paint and belongs to the field of paint. Specifically, it is a water-based metal antirust varnish and a preparation method thereof. Background technique [0002] The continuous improvement of today's material and spiritual life makes people have a special liking for the original ecological things, especially the best-selling log furniture all reflect people's desire for nature in the fast-paced and high-pressure environment. At present, there are many water-based antirust products on the market, but most of them are anti-corrosion through the addition of pigments and fillers, which cover the luster of the metal surface, and the antirust effect of varnishes without these fillers is very poor. Contents of the invention [0003] The purpose of the present invention is to provide a water-based metal antirust varnish, which is an environment-friendly anticorrosion paint. Another object of the present invention is t...
