The formula of the metal coating comprises, by mass, 55-75 parts of acrylic acid modified epoxy resin, 1-2 parts of a polyacrylate thickener, 2-6 parts of fumed alumina, 6-10 parts of modified polyurea, 4-6 parts of a composite heat insulation agent, 2-4 parts of caprin, 1-3 parts of low molecular polyethylene wax, 12-14 parts of hydroxyapatite nano-powder, 5-7 parts of boron carbide, 4-6 parts of mercaptobenzothiazole, 2-6 parts of zinc dihydrogen phosphate, 1-2 parts of an assistant and 1-3 parts of a wetting dispersant. The coating produced through using the formula and the production method has good metal corrosion resistance, good environmentally-friendly property and good heat insulation property.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a metal coating and a preparation method thereof. Background technique [0002] Corrosion of metals is a phenomenon in which metals are destroyed by electrochemical or chemical action of environmental media. Metal corrosion spreads across all fields of the national economy, bringing huge losses to the national economy. In industrially developed countries, the direct economic loss caused by metal corrosion accounts for 1% to 4% of the total output value of the national economy. The steel that rusts due to corrosion accounts for about 20% of the total output every year, and about 30% of the equipment is damaged by metal Corroded and scrapped. In China, the annual economic loss due to metal corrosion accounts for 4% of the gross national product. Because of this, metal anti-corrosion coatings with excellent rust resistance and chemical medium corrosion resistance have developed ...

Problems solved by technology

Due to the wide use of metal products, many metal products have been subjected to friction tests for a long time. If anti-corrosion coatings are not coated, the service life of metal products will be greatly reduced due to metal corrosion and friction. Coating anti-corrosion coatings can reduce corrosion, but the existing The environmental protection of existing metal anti-corrosion coatings is poor, and long-term and large-scale use is likely to cause a great impact on the surrounding environment, and the existing metal anti-corrosion coatings have poor heat insulation performance. Metal products often bring safety hazards due to high temperature, and commonly used water showers or air-conditioning cooling will cause a lot of waste of energy
