Problems solved by technology

[0002] At present, the idlers used in many domestic conveying machinery industries include steel pipes, nylon pipes, steel-coated rubber pipes, steel-coated PE pipes, etc. The simple use of steel pipes as idlers has defects such as easy rust, large frictional resistance, and serious wear on the conveyor belt. ; while using nylon tubes as idlers, the production length can only be within 500mm, and once it is extended, it cannot carry a large load; although the rubber covered with steel tubes has good elasticity, it also has the defect of large frictional resistance; For polyethylene pipes, although the interference fit can be used to reduce the gap between the steel pipe and the polyethylene pipe of the jacket during assembly, a certain amount of heat will be generated after friction during operation, and the polyethylene casing will be exposed to heat after being heated. The diameter expands, resulting in slippage, and the service life is affected to a certain extent

Abstract

The invention discloses an anticorrosion coating for pipes, which belongs to the technical field of pipes. In the present invention, through the fusion of resin and metal flakes, the metal flakes are in a resin-coated state and evenly distributed in the coating. The matrix path significantly reduces the permeability of the coating, better shields the environment from water, oxygen and other corrosive factors, thereby improving the wear resistance of the resin and making the pipe have better weather resistance.
