Abstract

The invention relates to high-stain-resistance elastic and round-shaped broom-finish emulsion paint. The emulsion paint is prepared from water, a pH regulating agent, a dispersing agent, a wetting agent, an anti-freezing agent, a defoaming agent, titanium dioxide, precipitated barium sulfate, heavy calcium carbonate, calcined kaolin, ultraviolet crosslinking type elastic emulsion, opaque polymer, a water-based paint enhancing agent, an adhesive force hanging agent, sterilization preservatives, a mould-preventing agent and a thickening agent. The emulsion paint overcomes the defects that existing elastic broom-finish emulsion paint cannot have high stain resistance and high elasticity at the same time, defoaming is difficult, and a preparation method is complicated, and has the advantages that high stain resistance (stain resistance is smaller than 15%) and high elasticity (normal-temperature break elongation is larger than 250%) are achieved at the same time, defoaming performance is excellent, the number of paint film pin holes is small, and the preparation method is simple and convenient.

Description

technical field [0001] The invention relates to a high-pollution-resistant elastic round-shaped brushed latex paint and a preparation method thereof, which are applied in the field of water-based paints for architectural decoration. Background technique [0002] At present, the base material of the exterior wall of buildings is generally cement-based. After being affected by factors such as environment, temperature and humidity changes, the wall is extremely prone to tiny cracks. This not only destroys the beauty of the wall, but also easily erodes the internal wall. [0003] Elastic latex paint can be divided into two types: elastic flat coating and elastic napping. The elastic flat coating is a thin coating (the dry film thickness of the coating film is about 60um), and the coating film is flat and smooth; while the elastic napping is a thick coating coating (the coating film thickness is about 300um), and the coating film is three-dimensional and uneven . The main diff...
