NOVELTY - The invention discloses a self-lubricating seal which is formed by spraying new graphene-containing material components on the surface of a rubber seal to improve the surface properties. The main process is to spray a surface friction layer with a thickness of 0.1-100u on the surface of the traditional rubber seal, which greatly improves the performance of the seal and can be used more effectively for piston seals, shaft seals, buffer seals, Solenoid valve seals, O-rings, special-shaped rings and other parts that are in contact with metal and move in friction. Disperse graphene evenly and effectively in the resin solution. The graphene content can be adjusted from 0.1% to 20% (100% of the total weight of the resin formulation) depending on the application function standard to adjust the different friction coefficient and lubricity of the object. . After spraying the surface of the seal, it can greatly improve the lubricity of the seal, reduce the friction and wear of the seal during movement, and can operate stably for a long time, effectively extending the pneumatic, hydraulic and other fields. The life of each element of linear motion, rotation and various motions, and reduce the energy consumption during work.
