Abstract

The invention relates to an organic and inorganic combined type stain resistance elastic flat emulsion paint. The organic and inorganic combined type stain resistance elastic flat emulsion paint is prepared from water, cellulose, a pH conditioning agent, a dispersing agent, a wetting agent, an antifreezing agent, a defoaming agent, titanium dioxide, filler, an ultraviolet photocrosslinking elastic emulsion, a water paint reinforcing agent, an antibacterial preservative, a mildew preventive, other thickening agents except cellulose and modified silica sol, wherein the filler is one or more or the combination of any two or more of coarse whiting, calcined kaolin, precipitated barium sulphate and talcum powder or mica powder. The organic and inorganic combined type stain resistance elastic flat emulsion paint overcomes the defects that an existing elastic flat emulsion paint is poor in stain resistance and weather resistance and has the advantages of being high in stain resistance (smaller than 12%), high in weather resistance, excellent in defoaming performance, easy and convenient to prepare and low in manufacturing cost.

Description

technical field [0001] The invention relates to an organic-inorganic compound type highly stain-resistant elastic flat coating latex paint and a preparation method thereof, which are applied in the field of water-based paint 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 membra...
