Corrosion-resistant metal coating and preparation method thereof

Abstract

The invention discloses a corrosion-resistant metal coating and a preparation method thereof. The corrosion-resistant metal coating comprises raw materials in parts by weight as follows: 10-50 parts of nano-zinc oxide, 10-50 parts of manganese dioxide, 50-60 parts of cerium oxide, 40-80 parts of castor oil polyoxyethylene ether, 10-20 parts of aluminum, 20-30 parts of copper, 20-100 parts of 2-hydroxyethyl methacrylate, 10-50 parts of 2-ethylene pyrrolidine and 20-30 parts of sorbic acid. The preparation method of the corrosion-resistant metal coating comprises the steps as follows: nano-zinc oxide, manganese dioxide, cerium oxide, aluminum, copper, 2-hydroxyethyl methacrylate, 2-ethylene pyrrolidine and sorbic acid are heated for 20-30 h at the temperature of 40-60 DEG C, then castor oil polyoxyethylene ether is added, the materials are mixed uniformly, a mixture is obtained, a metallic matrix is uniformly coated with the mixture and is dried, and the corrosion-resistant metal coating is obtained. The corrosion-resistant metal coating has excellent corrosion resistance.

Description

technical field

[0001] The invention relates to a corrosion-resistant metal coating and a preparation method thereof. Background technique

[0002] Coating is a solid continuous film obtained by one application of paint. It is a thin plastic layer coated on metal, fabric, plastic and other substrates for the purpose of protection, insulation and decoration. The paint can be gaseous, liquid, or solid, and the type and state of the paint are usually determined according to the substrate to be sprayed. Metal coating refers to: the covering layer prepared by thermal spraying method using metal as spraying material.
