Embodiment Construction

[0018] The embodiment of the forming method of graphene protective layer

[0019] Such as figure 1 As shown, the forming method of the graphene protective layer of the present invention first disperses the graphene anchored with lipophilic groups in a liquid to make a graphene suspension. By spraying the graphene suspension, the graphene suspension is sprayed at an initial spraying speed greater than 381m / s, and the graphene is spread on the surface of the resin matrix to form a graphene protective layer.

[0020] Preferably, the initial spraying velocity of the graphene suspension is greater than 420m / s. It is beneficial to further improve the initial kinetic energy of graphene suspension injection, and enhance the anchoring effect and binding force between the lipophilic groups of graphene and the groups of the resin matrix.

[0021] Preferably, the distance between the nozzle for spraying the graphene suspension and the resin matrix is ​​less than 5.5 cm. It is beneficia...

Abstract

The primary purpose of the invention is to provide a graphene protective layer and a molding method thereof, a compound thread fastening part and a compound gear. According to the graphene protectivelayer and the molding method thereof, the compound thread fastening part and the compound gear, graphene anchored with oil-wet groups is dispersed in liquid to form a graphene suspension solution, thegraphene is spread on the surfaces of a resin matrix, the compound thread fastening part and the compound gear to form the graphene protective layer by means of the manner of spraying the graphene suspension solution, graphene edge rejoining is facilitated to form the smooth protective layer, and the composite material abrasion resistance strength and impact resistant capacity are greatly improved.

Description

technical field [0001] The invention relates to a graphene protective layer and a forming method thereof, a composite threaded fastener and a composite gear. Background technique [0002] Graphene is one of the materials with the highest strength known, and it also has good toughness and can be bent. The theoretical Young's modulus of graphene reaches 1.0TPa, and its inherent tensile strength is 130GPa. Graphene has excellent wear resistance. Using graphene to make the wear-resistant layer of parts can effectively improve the impact resistance and wear resistance of parts and prolong the service life of parts. However, the graphene coating formed by the conventional spraying or brushing process is easy to fall off from the surface of the part, and it is difficult to give full play to the effect of the graphene coating. Contents of the invention [0003] The primary purpose of the present invention is to provide a method for forming a graphene protective layer with high ad...
