Problems solved by technology

[0004] At present, there are the following problems in the popularization and application of phosphate coating materials. The addition of basic metal oxide curing agents can effectively reduce the curing temperature of the coating, but the use of low-activity curing agents with relatively poor curing effects cannot effectively reduce the temperature of phosphate coatings. temperature, while the strong curing agent is easy to cause the curing reaction to be too fast, which affects the overall performance of the coating after curing and cannot form a film

Abstract

The invention discloses an inorganic anticorrosive paint. The inorganic anticorrosive paint is prepared from the following raw materials in parts by weight: 80-90 parts of an aluminum dihydrogen phosphate adhesive, 10 to 15 parts of a curing agent, 1-4 parts of an auxiliary agent, 1-4 parts of a filler and 80 to 90 parts of distilled water, wherein the curing agent is a mixture of zinc oxide, magnesium oxide and nickel oxide, the auxiliary agent is a mixture of borax and polydimethylsiloxane, and the filler is a mixture of calcium aluminate, magnesium sulfate and nanometer molybdenum disulfide. The inorganic anticorrosive paint provided by the invention can realize self-curing at room temperature, does not release VOC, and has good corrosion resistance, heat resistance and water resistance.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to an inorganic anti-corrosion coating and a preparation method thereof. Background technique [0002] Metal materials such as iron and steel are widely used in various fields of national economic construction, but their poor corrosion resistance also limits their application. Among them, anti-corrosion coating has become one of the most commonly used and effective methods to prevent corrosion of metal materials such as steel. Anti-corrosion coating materials refer to materials that can be cured to form a tough protective film coated on the surface of metal materials such as steel. However, most of the polluting raw materials contained in organic coatings will be lost to the surrounding environment during production and application, causing certain harm to the human body and the environment. At the same time, the limited high temperature resistance of organic coatin...
