Abstract

The invention relates to high-cost-performance and high-stain-resistance elastic flat-coating emulsion paint. The emulsion paint is prepared from water, cellulose, a pH regulating agent, a dispersing agent, a wetting agent, a wetting anti-freezing agent, an anti-freezing agent, a defoaming agent, titanium dioxide, filler, ultraviolet crosslinking type elastic emulsion, a water-based paint enhancing agent, sterilization preservatives, a mould-preventing agent and other thickening agents except cellulose, wherein the filler is prepared from one or any combination of heavy calcium carbonate, calcined kaolin, precipitated barium sulfate, talcum powder and mica powder. The emulsion paint overcomes the defects that existing elastic flat-coating emulsion paint cannot have high stain resistance and high elasticity at the same time, and a preparation method is complicated, and has the advantages that high stain resistance (stain resistance is smaller than 15%) and high elasticity (room-temperature tensile strength is larger than 2.5 MPa, normal-temperature break elongation is larger than 300%, and low-temperature break elongation is larger than 80%) are achieved at the same time, defoaming performance is excellent, manufacturing cost is low, cost performance is high, and the preparation method is simple and convenient.

Description

technical field [0001] The invention relates to a cost-effective, highly stain-resistant elastic flat-coated 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 is divided into two types: elastic flat coating and elastic napping. The elastic flat latex paint 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 brushed latex paint is a thick coating (the film thickness is about 300um), and the coating film is flat and smooth. The membrane is three-dimen...
