Quick-drying sand textured coating

Abstract

The invention belongs to the technical field of quick-drying coatings, and concretely relates to a quick-drying sand textured coating. The quick-drying sand textured coating is disclosed to overcome the defects of too long surface drying time of sand textured coatings and uneven distribution of solid components in coatings due to direct addition of a quick-drying assistant. The quick-drying sand textured coating comprises 5-10 wt% of water, 2-6 wt% of the quick-drying assistant, 15-20 wt% of an emulsion, 70-75 wt% of a pigment filler and 1-5 wt% of assistants, and the assistants include a wetting agent, a dispersant, a thixotropic agent and a thickener. The emulsion is a 40-60 wt% styrene acrylic emulsion or a pure acrylic emulsion. A film forming assistant, an anticorrosive bactericide and an antifreeze agent can be selectively added to the assistants. The coating is suitable for brushing exterior walls of buildings.

Description

technical field [0001] The invention belongs to the technical field of quick-drying coatings, in particular to a quick-drying sand wall-like coating. Background technique [0002] Due to its rich texture, strong three-dimensional effect and various colors, the sand wall-like paint can be made into different textures and colors such as imitation marble and imitation granite by using different construction methods, and is mostly used for exterior wall coating of buildings. [0003] However, due to the high content of solid materials such as sand grains in the sand wall-shaped coating, after being coated on the surface of the substrate, these solid materials will hinder the volatilization of water. Therefore, the surface-drying time of sand-wall-like coatings is long, especially in areas with low temperature and high humidity in the south in winter. Damage such as rainwater has become a difficult problem in the industry. [0004] If you directly add anhydrous ethanol and othe...
