Abstract

The invention discloses zinc-aluminum coating anti-corrosion paint. The paint is composed of two-components of A and B in a mass ratio of 3:1, wherein a component A comprises the following raw materials: zinc aluminum alloy powder, nano-silica, sodium lignosulphonate, benzotriazole, thiodiethylene glycol, amino trimethylene phosphonic acid, sodium carboxymethylcellulose and deionized water; a component B comprises the following raw materials: zircinium fluoride, gamma-aptes, inositol hexaphosphate, cellaburate, ethanol and the deionized water, wherein the zinc aluminum alloy powder is composedof Zn, Al, Ti, Ni, Mg and Mn. According to the zinc-aluminum coating anti-corrosion paint and the preparation method thereof, excellent corrosion resistance and impact resistance are acquired and a deficiency that the production process of triphenylphosphine in the prior art has potential dangers on environmental safety and operators is compensated by means of adjusting mass ratio of each component of the zinc aluminum alloy powder on the basis of replacing the triphenylphosphine with the amino trimethylene phosphonic acid and the sodium carboxymethylcellulose.

Description

technical field [0001] The invention relates to a metal anticorrosion coating, in particular to a zinc-aluminum coating anticorrosion coating. Background technique [0002] Anti-corrosion coating refers to a type of liquid or solid material that can form a thin film on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. There are three main functions: protection, decoration, and concealing the defects of the product to enhance the value of the product. The anti-corrosion coating is formed after drying and curing on the surface of the substrate to be coated. Its protective effect mainly includes the following three types. Shielding effect. According...
