Problems solved by technology

Traditional organic coatings, etc., have a huge impact on the environment. Not only the finished products often emit greenhouse gases and cause climate warming, but also release toxic substances in the air, causing diseases and deaths of people, animals and plants. It also consumes a lot of energy, does not meet the concept of low-carbon in my country, and produces various industrial sewage or toxic gases

Description

technical field [0001] The invention relates to the technical field of ceramic coatings, in particular to a high-temperature-resistant, high-blackness, anti-coking, and corrosion-resistant ceramic coating. Background technique [0002] Ceramic coatings belong to the field of functional coatings and are a new type of water-based inorganic coatings. It is mainly composed of nano-inorganic compounds and water as a dispersant. After coating, it is usually cured by low-temperature heating to form a coating film with properties similar to ceramics. Its raw materials are abundant, easy to mine and low in price, which makes its cost lower than traditional coatings. Some of them use silane coupling agent and aluminum hydroxide colloid to prepare ceramic coatings, which have many advantages such as high temperature resistance, high hardness, non-flammable and smoke-free, super weather resistance, environmental protection and non-toxic, rich colors, and easy coating. After various ne...
