Abstract

The invention relates to the field of a chemical coating, in particular to white-washed two-component water-based paint with a matt surface. The formula of the white-washed two-component water-based paint with the matt surface comprises a main agent and a curing agent, wherein the main agent comprises components in percentage by mass as follows: 50%-70% of a water-based acrylic polyol dispersion, 1%-10% of butyl cellosolve, 1%-5% of titanium dioxide, 0.5%-10% of a matting agent, 0.5%-4% of a functional assistant and 10%-30% of distilled water. The formula can improve the rigidity and chemical resistance of the two-component water-based paint with the matt surface, so that the two-component water-based paint can compare favorably with the traditional oil paint, and real high environmental-protection and high-performance requirements for the paint are met.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a water-washed white two-component water-based matte finish. Background technique [0002] With the progress of society, the awareness of environmental protection in the whole society has generally improved, especially the strict restrictions on VOC content in coatings in various countries' environmental protection regulations, and water-based two-component coatings are ushering in development opportunities. Water-based two-component coatings combine the high performance of similar solvent-based coatings with the low VOC content of water-based coatings. They have good environmental effects and relatively convenient construction. They are widely used in wood furniture, architectural decoration, and automotive coatings. At the same time, as my country's technology is becoming more mature, the cost of raw materials has been significantly reduced, and the degree of localization has b...
