Abstract

The invention provides a highly stable latex paint and a preparation method thereof. The latex paint comprises 20-50 parts of a styrene acrylic emulsion, 2-8 parts of propylene glycol, 8-18 parts of hydroxyethyl cellulose, 7-16 parts of 3-aminopropyltriethoxysilane modified aqueous polyurethane, 5-10 parts of attapulgite, 0.1-2 parts of a mildew inhibition bactericide, 5-8 parts of dibutyl phthalate, 0.1-0.5 parts of an antifoaming agent and 20-55 parts of water. The latex paint has the advantages of simple formula, environmentally-friendly and pollution-free preparation process, strong environment resistance, difficult water separation and good levelability.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a high-stability latex paint and a preparation method thereof. Background technique [0002] Latex paint is widely used in interior wall and exterior wall decoration because of its excellent characteristics. Due to the difference in construction process and construction environment, there are higher requirements for the quality of latex paint film formation. However, the existing latex paints have poor environmental adaptability and are prone to water separation and layering; in view of the problem of water separation, enterprises have produced a variety of latex paints, but after solving the problem of water separation, it is easy to cause poor film-forming properties. Contents of the invention [0003] The problem to be solved by the present invention is to provide a latex paint with good stability, high temperature and low temperature resistance, good film-forming property and high s...
