Abstract

The invention belongs to the technical field of anticorrosive paint preparation, and provides noise reduction graphene anticorrosive paint for rail facilities and a preparation method thereof. The method is characterized in that after sodium dioxide powder and graphene powder are mixed, the mixture is preheated in a coating pan and rotates; molten state waterborne polyurethane is sprayed onto thepowder surface; the powder is coated to form a uniform thin film encapsulation layer; after cooling, a paint additive is obtained; before the paint is used, the paint additive is added into the paint;uniform mixing is performed; along with the dissolution of the thin film, sodium dioxide and water react to generate gas; bubble holes are formed; secondary dispersion of the graphene is promoted; the noise reduction graphene anticorrosive paint is obtained. Compared with that of a traditional method, the graphene paint prepared by the preparation method can effectively prevent the interlayer reunion phenomenon of the graphene; meanwhile, micropores can be formed; a certain noise reduction effect and good mechanical performance and anticorrosion performance are realized; the preparation mechanical equipment is simple and common; the energy consumption is low; the product quality is easy to control; the environment-friendly performance is good.

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...
