Abstract

The invention belongs to the technical field of preparation of anti-corrosion coatings, and provides a noise-reducing graphene anti-corrosion coating for railway facilities and a preparation method thereof. In this method, sodium peroxide powder and graphene powder are mixed, preheated and rotated in a coating pan, and the molten water-based polyurethane is sprayed on the surface of the powder, and the powder is coated to form a uniform film encapsulation layer, and the coating additive is obtained after cooling. , before the paint is used, it is added to the paint and mixed evenly. As the film dissolves, sodium peroxide reacts with water to generate gas, forming cells and promoting the secondary dispersion of graphene to obtain a noise-reducing anti-corrosion paint. Compared with the traditional method, the graphene coating prepared by the present invention can effectively prevent the interlayer repolymerization of graphene, and can form micropores at the same time, has a certain noise reduction effect, better mechanical properties and anti-corrosion properties, and is suitable for preparing mechanical equipment Simple and common, low energy consumption, easy to control product quality, and good environmental friendliness.

Description

technical field

[0001] The invention belongs to the technical field of preparation of anti-corrosion coatings, and provides a noise-reducing graphene anti-corrosion coating for railway facilities and a preparation method thereof. Background technique

[0002] In chemical, petroleum, food, light industry and other industries, most equipment and pipelines are corroded due to the existence of corrosive media. The concentration and temperature of corrosive media change at any time and act alternately, so the corrosion is very serious. Using various anti-corrosion materials to make the covering layer or lining is to completely isolate the metal equipment from the corrosive medium, prevent corrosion and abrasion of the equipment, and improve the corrosion resistance, wear resistance, safety and service life of the equipment. With the rapid development of science and technology, anti-corrosion technology has also entered a new stage, and various new anti-corrosion materials and con...
