Abstract

The invention discloses water-based metal primer-finish combined paint. The water-based metal primer-finish combined paint comprises, by weight, 5-6% of water, 0.1-0.4% of magnesium aluminum silicate,0.5-0.6% of a dispersant, 0.1-0.2% of a wetting agent, 0.1-0.3% of a defoamer, 0.2-0.5% of a pH regulator AMP-95, 12-18% of R-760 titanium dioxide, 2-5% of zinc phosphate, 3-5% of barium sulfate of 1000 meshes, 1-3% of mica powder of 1000 meshes, 50-55% of an water-based acrylic industrial emulsion, 2-3% of a film former Texanol, 0.5-1% of an anti-flash rust agent, 0.1-0.5% of a preservative, 0.1-0.5% of a polyurethane thickener, 0.1-0.2% of a substrate wetting agent and the balance of water.

Description

technical field [0001] The invention relates to the technical field of water-based anti-corrosion coatings, in particular to a water-based metal bottom and surface all-in-one paint and a preparation method thereof. Background technique [0002] Effective anti-corrosion measures for metal materials can save resources, energy, and reduce sudden safety accidents. , saving energy and other advantages, it has become the most effective, economical and widely used anti-corrosion method. Among them, acrylic resin coatings have many advantages that other resins cannot match, such as light aging resistance, strong outdoor exposure durability, not easy to decompose and turn yellow under ultraviolet light, good acid and alkali resistance, and good corrosion resistance to metal substrates. In recent years, with the increasing attention to environmental protection issues, the development and research of water-based acrylic resin coatings are particularly important. [0003] Although the...
