Abstract

The invention relates to a water-based highlight two-component acrylic polyurethane coating and a preparation method thereof, and belongs to the technical field of coatings. The coating comprises a component A and a component B, wherein the component A comprises the following components in parts by weight: 20-40 parts of a water-based hydroxy acrylic acid dispersion I; 20-40 parts of a water-basedhydroxy acrylic acid dispersion II, 0-0.5 part of a pH regulator, 1-5 parts of a conventional auxiliary agent, 1-6 parts of a coalescing agent, 1-25 parts of a pigment filler, 0-1.5 parts of a special auxiliary agent, 0.1-0.5 part of bentonite, 5-20 parts of deionized water, 0-1 part of a flash rust inhibitor and 0-1 part of a thickening agent. And the component B comprises the following components in parts by weight: 20-70 parts of an isocyanate curing agent I, 20-70 parts of an isocyanate curing agent II and 0-30 parts of a cosolvent. The two-component coating disclosed by the invention hasthe advantages of high gloss, high fullness and small fog shadow, and the problems of low performance and poor appearance of a water-based coating are solved.

Description

Technical field [0001] The invention belongs to the technical field of coatings, and specifically relates to a water-based high-gloss two-component acrylic polyurethane coating and a preparation method thereof. Background technique [0002] Water-based paint is a paint that uses water as a solvent. Using water as a diluent during construction greatly reduces the use of toluene and xylene, and reduces VOC emissions. In this way, the use of environmentally friendly water-based coatings can protect human life and property safety while reducing pollution to the atmospheric environment. At present, in the high-end industry, the proportion of water-based paints and domestic paints is relatively low, and its restrictive conditions are mainly in the performance and appearance of water-based paints. The present invention introduces a high-performance acrylic polyurethane paint and its preparation method. Performance and appearance can meet the requirements of high-end industries. Summar...
