Organosilicon weatherproof batch scraped natural stone-like paint and preparation method thereof

Abstract

The invention provides organosilicon weatherproof batch scraped natural stone-like paint. The organosilicon weatherproof batch scraped natural stone-like paint is characterized by being prepared from25 wt% of a component A, 3 to 5 wt% of a component B and 70 to 72 wt% of a component C, wherein the component A comprises 27 to 37.65 wt% of water, 0.8 to 1 wt% of cellulose ether, 0.15 to 0.2 wt% ofa pH value regulator, 10 to 18 wt% of film forming organosiloxane modified acrylic emulsion, 45 wt% of film forming silicone emulsion, 2.5 to 3. 5 wt% of a film forming additive, 3 to 4 wt% of a coalescent additive, 0.2 to 0.3 wt% of a defoamer, 0.3 to 0.4 wt% of a thickener and 0.4 to 0.6wt% of a bactericide; the component B comprises 94.6 to 97.6 wt% of water, 2 to 3 wt% of an organic modified thickener and 0.4 to 0.6 wt% of a bactericide; the component C comprises natural colored sand. The organosilicon weatherproof batch scraped natural stone-like paint disclosed by the invention has goodpaint film hydrophobicity, waterproofness, permeability, weather resistance and stain resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a silicone weather-resistant scratch-off type natural stone paint and a preparation method thereof. Background technique [0002] Natural real stone paint is a very popular product type in the architectural coating industry in recent years. The product is mainly composed of acrylic emulsion and natural colored sand. Matched. This product has the texture effect of natural stone, and the coating film has a long-lasting hydrophobic effect, one-way waterproof and breathable, excellent durability, no fading, strong crack resistance, and beautiful decorative effect. This product is also a very popular decoration in the market now. One of the systems. [0003] The research and development of natural stone paint technology has been relatively mature. At present, the main work is to improve the construction, weather resistance and stain resistance of the product. However, the const...

Problems solved by technology

[0003] The research and development of natural stone paint technology has been relatively mature. At present, the main work is to improve the construction, weather resistance and stain resistance of the product. However, the construction process of the product has a greater impact on the stain resistance of the product. At present, the real stone paint on the market The paint is still mainly sprayed with styrene-acrylic or pure acrylic emulsion. The spraying effect of the paint film is relatively rough, and it is easy to accumulate serious dust. The surface of the batch-scraped real stone paint is relatively smooth, and the addition of silicone resin greatly enhances the paint film of the product. Surface hydrophobicity, coating waterproof and breathable, weather resistance, the greater advantage lies in saving labor and air pollution in the process (compared with spraying)
