Abstract

The invention relates to the technical field of exterior wall decoration materials, in particular to a silica sol composite thermal insulation real stone paint. The silica sol composite thermal insulation real stone paint is prepared from, by mass, 120 parts of water, 1 part of bactericide, 1 part of 5040 dispersing agent, 0.5 part of bentonite, 6 parts of ethylene glycol, 3 parts of titanium dioxide, 1 part of cellulose, 3 parts of coalescing agent, 1 part of AMPO-95, 80-100 parts of emulsion, 0-40 parts of silica sol, 500 g of 40-80-mesh white sand and 250 g of 80-120-mesh white sand. According to the silica sol composite thermal insulation real stone paint, silica sol is added into the real stone paint according to a certain proportion, the water resistance, the heat resistance and the anti-pollution capacity of the silica sol composite thermal insulation real stone paint are greatly improved, and the silica sol composite thermal insulation real stone paint has remarkable application and popularization significance.

Description

technical field [0001] The invention relates to the technical field of exterior wall decoration materials, in particular to a silica sol composite thermal insulation genuine stone paint. Background technique [0002] Real stone paint is a kind of polymer emulsion as the base material, adding a small amount of film-forming additives as the bonding material, using natural colored sand with different colors and meshes as the aggregate, and adding a series of additives and deionized water quantitatively. A polymer emulsion sand-wall-like high-build coating system prepared by physical uniform blending. As a good water-based paint, it has the advantages of safety, non-toxicity and rich texture. In addition, it also has the characteristics of realistic intercourse, and the decorative effect is similar to marble and granite, highlighting the heavy style and stone-like style. It is a high-quality, high-performance architectural coating. [0003] Polymer emulsion is the most importa...
