Abstract

The invention belongs to the field of building coating materials, and provides a macadam real paint and a preparation method thereof, wherein the macadam real paint comprises a silicone acrylic emulsion, natural colored stone powder, hydroxyethyl cellulose, propylene glycol, dodecyl alcohol ester, a thickener and a preservative. According to the invention, the silicone acrylic emulsion has good film-forming property, the hydroxyethyl cellulose can improve the surface viscosity of the macadam real paint and improve the fluidity of the macadam real paint, the propylene glycol can improve the frost resistance of the macadam real paint, the natural colored stone powder can endow the macadam real paint with gorgeous colors, the dodecyl alcohol ester can improve the film-forming property of thesilicone acrylic emulsion, reduce the lowest film-forming temperature of the silicone acrylic emulsion and enhance the coating adhesive force of the macadam real paint, the thickener can improve the surface viscosity of the macadam real paint and prevent the macadam real paint from precipitating in the storage process, and the preservative can prevent the macadam real paint from decaying or beinginfected with mould when the macadam real paint is stored in the container; and the macadam real paint has good color, good pattern, good stone-like effect after being used, and is strong in decoration.

Description

technical field [0001] The invention belongs to the field of architectural coatings, in particular to a gravel real paint and a preparation method thereof. Background technique [0002] Crushed stone real lacquer belongs to a kind of real stone varnish. Real stone varnish is a kind of paint with a decorative effect similar to marble or granite. It is applied to the exterior wall of a building and has the effect of imitating stone, so it is also called liquid stone. Compared with other types of coatings, real stone paint also has the advantages of strong decoration, wide application range, water-based environmental protection and good stain resistance. [0003] After the existing crushed stone lacquer is used, it is prone to strength reduction and dry cracking in a long-term low-temperature environment, and its performance in terms of stability, dry crack resistance and workability still needs to be improved. Contents of the invention [0004] The invention provides a crus...
