Sand-in-sand multicolor interior and exterior wall building coating material and preparation method thereof

Abstract

The invention discloses a sand-in-sand multicolor interior and exterior wall building coating material and a preparation method thereof, and relates to the field of building coating materials, whereinthe components of the formula comprise: a granulating agent, cellulose, a pH value regulator, a bactericide, inorganic bentonite, an anti-freezing agent, a film forming aid, a granulating emulsion, sand, an emulsion, a dispersing agent and titanium dioxide. The preparation method comprises: preparing a white base paint, preparing a granulating agent system, granulating, preparing a real stone paint and preparing a finished product. According to the invention, based on the sand-in-water multicolor coating material, through the specially-made granulating agent adding and the process, the sand-in-water color particles have characteristics of low use amount of, various colors, stone-like fidelity and the like, the real stone paint has advantages of favorable constructability, high storage stability and favorable texture effect, and the sand-in-water color particles and the real stone paint are combined to form the completely-new sand-in-sand multicolor coating material, so that the existing technical difficulties are solved, and the existing comprehensive advantages are retained.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to sand-in-sand colorful interior and exterior wall architectural coatings and a preparation method thereof. Background technique [0002] Real stone paint and water-in-sand are usually used in the existing interior and exterior wall coatings of buildings. When the coating of real stone paint is thicker during use, the paint consumption is large, and the sand fall is serious during the spraying process, which produces smog that pollutes the environment. When it is thinner, the effect of covering the background color is poor, resulting in quality problems such as layering and whitening of the coating, and the real stone paint is too rough and poor in stain resistance; the construction technology of water-in-sand is too high, and the color particles are fragile and blurred , the pressure is too low and the material is uneven, the progress of the project is too slow, which affects...

Problems solved by technology

[0002] Real stone paint and water-in-sand are usually used in the existing interior and exterior wall coatings of buildings. When the coating of real stone paint is thicker during use, the paint consumption is large, and the sand fall is serious during the spraying process, which produces smog that pollutes the environment. When it is thinner, the effect of covering the background color is poor, resulting in quality problems such as layering and whitening of the coating, and the real stone paint is too rough and poor in stain resistance; the construction technology of water-in-sand is too high, and the color particles are fragile and blurred , the pressure is too low and the material is uneven, the progress of the project is too slow, which affects the project delivery date, wastes manpower and material resources, and the sand in water has poor stability and is not easy to store. Color mixing in the packaging barrel, spraying is not clear
