Inorganic ceramic paint

Abstract

The invention relates to a building coating, in particular to an inorganic ceramic coating used for building walls or decorative panels. It contains 34-56% of water-based silica sol, 26-46% of alumina or hydrated alumina, 1-7% of water-soluble alcohol amine, 2-13% of calcium oxide or calcium hydroxide, and the rest for water. The invention can make a variety of building substrates (such as ceramics, glass, concrete, calcium silicate board, etc.) have good adhesion coating, and the obtained coating has excellent hardness, water resistance, stain resistance, Acid and alkali resistance, non-combustible, easy to use, can be widely used in building exterior walls and decorative panels.

Description

technical field

[0001] The present invention relates to a kind of architectural paint, especially relate to a kind of inorganic ceramic paint that is used for building wall or decorative plate. Background technique

[0002] The development and application of inorganic architectural coatings began after the oil crisis in the early 1970s, and a more economical and durable coating was demanded in the market. At that time, Japan first successfully researched and developed coatings with silicate inorganic polymers as film-forming substances. German companies such as BASF, Wacker, Bayer and Keimfarben also successively developed special liquid potassium silicate as the main film-forming substance. new inorganic coatings. Since then, the United States has also developed rapidly in inorganic coatings and inorganic-organic composite coatings. Since the early 1980s, there have been reports of successful research on this type of coating in my country, mainly inorganic coatings based ...
