Aqueous exterior wall coating material with high solid content and low viscosity

Abstract

The invention discloses an aqueous exterior wall coating material with high solid content and low viscosity. The coating material with low viscosity and easy construction can be prepared by the following steps of: fully mixing components such as water, a dispersion stabilizer, a filler with high covering power, a wetting agent, titanium white, aqueous styrene-acrylic emulsion with high solid content, elastic acrylic acid emulsion with high solid content, a pH regulator, an antifoaming agent, a thickening agent, a film-forming additive and the like according to a certain process flow; and reasonably matching and combing the filler with high covering power and other components by fully utilizing the high solid content and high stabilizing effect of the aqueous styrene-acrylic emulsion and the high-efficiency film-forming property and weather resistance of the elastic acrylic acid emulsion. The coating material can directly achieve the construction effect during the construction of an exterior wall and can achieve the effect of high covering power without being thinned by adding water.

Description

technical field

[0001] The invention relates to a paint, in particular to a water-based high-solid-content low-viscosity exterior wall paint for building exterior walls. Background technique

[0002] With the improvement of people's living standards and the continuous development of society, people pay more and more attention to the choice of architectural decorative coatings. The simpler the construction requirements for coatings, the better. In terms of the protection of the substrate, at the same time, the construction of the coating is required to be simple and convenient, and at the same time, it is required to maintain high decorative requirements such as color retention.

[0003] At present, when ordinary exterior wall coatings are used as architectural decoration coatings, they need to be diluted with water during construction, and the construction period is relatively long. Usually, a primer is applied, and a second topcoat is required at the same time to achieve a ...
