A kind of nano-magnesium-aluminum corrosion-resistant coating and preparation method thereof

Abstract

The invention discloses a nano magnesium-aluminum anti-corrosion coating. The coating comprises a first component and a second component, wherein the second component is formed by mixing a component A with a component B; the first component comprises components as follows: epoxy resin, hydroxyl acrylic resin and ammonium dihydrogen phosphate; the component A comprises components as follows: nano magnesium oxide, nano aluminum oxide, nano titanium dioxide, nano zirconium dioxide, nano rare earth oxide and deionized water; the component B comprises components as follows: butanol, filler, barium sulfate, diethylenetriamine and dipropylene glycol butyl ether. The invention further discloses a preparation method of the nano magnesium-aluminum anti-corrosion coating. The coating is high in mechanical strength and excellent in wear resistance, hardness, compressive strength and impact resistance, meanwhile, the preparation technology is simple and easy to operate, the cost is lower, the production process is safe and environment-friendly, and no pollutant is produced.

Problems solved by technology

[0003] With the rapid development of industries such as aviation, aerospace, automobiles and weapons, the requirements for the performance of metal materials are getting higher and higher. Not only are metal materials required to work normally at higher temperatures and harsher corrosion environments, but also It is difficult for organic polymer materials to meet the current use requirements if metal materials have good performances such as anti-vibration, anti-fatigue, anti-temperature sudden change and anti-scouring.

Ordinary coatings generally cannot form a dense protective layer through self-reaction at a certain temperature, and it is also impossible to react with metal materials in a short period of time to form a metal complex layer, thereby producing good adhesion; When used at the above temperature, the traditional coatings are somewhat insufficient in terms of heat and humidity resistance, salt spray resistance and high and low temperature performance.
