Abstract

The invention provides a graphene preservative and a corrosion control method for a mounting bracket. The graphene preservative can permeate into a honeycomb structure and form a dense protective filmon the surface of the honeycomb structure, and has good acid resistance, salt resistance and corrosion resistance. According to the corrosion control method for the passenger dedicated signal devicemounting bracket, first a zincizing corrosion resistance technology is adopted to form a honeycomb zinc-iron alloy layer on the surface of a workpiece, and the graphene preservative is sprayed in a pressure environment of 0.4-0.6 MPa. The graphene preservative undergoes multiple physical and chemical reactions, and a labyrinth effect is formed on the honeycomb zinc-iron alloy layer by overlappingdistribution, and the graphene preservative fills tissue gaps. A graphene coating is evenly distributed, the extremely low gas or liquid permeability of the coating can be maintained, and a corrosivemedium diffusion way is effectively blocked. At the same time, an anode material is added in the graphene, so that the coating has a self-healing function, and even if the graphene coating is partially damaged, the corrosion can also be effectively suppressed, thereby achieving long-term corrosion protection.

Description

technical field [0001] The invention belongs to the field of engineering equipment anticorrosion, and in particular relates to a graphene anticorrosion agent and an anticorrosion method for a mounting bracket. Background technique [0002] The railway signal indicates the command of train operation and shunting operation, and uses the color, shape, position and sound of specific objects to convey information to railway drivers about the road conditions ahead, the operating conditions of rolling stock, the status of driving equipment, and driving orders. equipment. Railway signals are like the eyes, ears and central nervous system of human beings. They have the functions of organizing and commanding train operation, ensuring driving safety, improving transportation efficiency, transmitting driving information, and improving the working conditions of driving personnel. The installation of passenger-only signal equipment usually requires the help of installation brackets, and ...
