. So what is an inorganic coating? As far as its name is concerned, we can define it like this: the coating made of inorganic binder material as the main binder, combined with certain additives and pigments and fillers, we call it inorganic coatings. There is a quantitative problem in this concept of "inorganic binder material as the main binder". At present, the industry generally believes that the coating with an organic content of less than 5% is an inorganic coating. Due to its unique properties and uses, inorganic coatings are a newer and better choice for the decoration industry!
Inorganic coatings are inorganic polymer coatings composed of inorganic polymers and dispersed and activated metals, metal oxide nanomaterials, and rare earth ultrafine powders. They can quickly react with iron atoms on the surface of steel structures to form Physical and chemical dual protection, inorganic polymer anti-corrosion coating firmly combined with the substrate through chemical bonds, no pollution to the environment, long service life, anti-corrosion performance has reached the international advanced level, is a high-tech replacement product that meets environmental protection requirements.
In recent years, due to the government's emphasis on environmental protection, inorganic coatings have been re-emphasized by the industry. The environmental protection mentioned by the government here is not limited to the environmental protection of this material, but focuses on the impact on the environment during the entire production and use process of this material (including raw material production, coating processing, construction and coating film aging). influence as low as possible. For example, air pollution is mainly dust pollution and VOC (volatile organic compound) pollution. Dust pollution is mainly inorganic mineral dust and organic particles (mainly incomplete combustion or sintered particles produced by high temperature). Most of the harm to the environment caused by inorganic mineral dust is temporary and limited, while the harm to the environment caused by organic particles and VOC is obvious to all. Therefore, in modern life, organic products (including latex) produced from petroleum and coal produce a lot of pollution in the production process (monomer production, polymerization, secondary recycling, and scrap treatment). Reducing the production and use of organic products is the fundamental solution to the current air pollution. Inorganic coatings conform to such requirements.

First of all, the base materials of inorganic coatings are often directly taken from nature, so the sources are very rich. For example, coating base materials such as silica sol and silicate solution are mainly derived from quartz ore, which is an extremely abundant material in nature.

Secondly, compared with some organic coating base materials, the production and use of inorganic coating base materials have less environmental pollution, and most of the products use water as the dispersion medium, which is environmentally friendly and healthy. side effects.

Third, the aging resistance and certain physical and chemical properties of inorganic coatings are difficult to achieve for most organic coatings with the same production cost, so they have better technical and economic performance.

Fourth, most of the inorganic coatings are alkaline, which is more suitable for application on bases such as cement and lime sand, which are also alkaline, and can chemically react with lime in these substrates to form silicon Calcium acid crystals can be integrated with the base layer, so its adhesion is particularly good.
