Abstract

The invention provides normal-temperature air drying type single-component water-based acrylic anticorrosion finish paint. The normal-temperature air drying type single-component water-based acrylic anticorrosion finish paint is characterized by being prepared from the components in parts by weight: 30-65 parts of water-based acrylic resin, 11-15 parts of mica powder, 2-5 parts of a dispersing agent, 1-5 parts of a defoaming agent, 2-5 parts of talcum powder, 5-10 parts of polyethylene glycol dioleate, 0.5-3 parts of kieselguhr, 0.5-6 parts of a flexibilizer, 0.5-5 parts of texanol ester alcohol, 1-5 parts of titanium dioxide, and 15-30 parts of deionized water. The water-based acrylic resin is adopted as a base material, the special composite flexibilizer is adopted, excellent ageing resistance is achieved, weather resistance is high, an experiment shows that ultraviolet light aging resistance can reach 600 h, a coating is flat and bright, the excellent adhesive capacity to a bottom layer is achieved, water resistance and outdoor durability are good, and excellent properties of natural drying and quick drying are achieved.

Description

technical field [0001] The invention relates to a paint, in particular to a normal-temperature self-drying one-component water-based acrylic anti-corrosion finish paint. Background technique [0002] There are also some paints for spraying on the surface of objects in the prior art, but the spraying effect is not very satisfactory, and there are shortcomings such as poor appearance quality, easy corrosion, wear, and poor outdoor weather resistance, thereby affecting the appearance quality and image of the object. Moreover, traditional metal coatings are all solvent-based products with high VOC (volatile organic compound) content. During the process of manufacturing, construction, drying, and curing to form a film, the VOC emitted into the air will seriously pollute the environment. With the increasingly stringent environmental protection regulations, the coating industry has gradually developed in the direction of pollution-free, pollution-free, energy-saving, environmentall...
