Embodiment 1

[0016] The anti-friction material includes the following components by weight percentage: 10% of nanometer molybdenum disulfide, 80% of graphite, 5% of graphene, and 5% of titanium dioxide.

Embodiment 2

[0018] The anti-friction material includes the following components by weight percentage: 12% of nano-molybdenum disulfide, 74% of graphite, 6% of graphene, and 8% of titanium dioxide.

Embodiment 3

[0020] The anti-friction material includes the following components by weight percentage: 20% of nano-molybdenum disulfide, 60% of graphite, 10% of graphene, and 10% of titanium dioxide.

[0021] Graphite is a hexagonal crystal with a coefficient of friction of 0.05 to 0.19. It is in the shape of scales and has a stable structure. The carbon atoms are firmly combined and are not easily damaged. The bonding force between layers is weak, and it is easy to slip under the action of shear force. It has a good filling and repairing effect on the friction surface, and is easy to form a covering film on the metal surface. It is a good solid lubricant.

[0022] Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It is composed of a single layer of atoms, and the carbon atoms are connected to each other to form a hexagonal grid. Its specific gravity in oil is low.

[0023] The structure of molybdenum disulfide is the same as that of graphite, which i...

Abstract

The invention relates to an anti-attrition material. The anti-attrition material contains the following ingredients in percentage by weight: 10-20% of nano molybdenum disulfide, 60-80% of graphite, 5-10% of graphene and 5-10% of titanium white. The anti-attrition material has the beneficial effects that graphite is used for filling and repairing a rough metal surface and plays a role in reducing attrition, nano molybdenum disulfide is suspended into grease in the presence of graphene, forms a cover film on the metal surface and has extreme pressure resistance, and the suspended nano molybdenum disulfide can be continuously filled to the worn metal surface again even if the generated film is worn, so that the anti-attrition material plays a role in reducing attrition and lubricating and meanwhile plays a role in saving energy, protecting environment, increasing speed, resisting extreme pressure attrition, resisting oxidation and the like.

Description

technical field [0001] The invention relates to a wear-reducing material. Background technique [0002] At present, friction and wear are the main reasons for the damage of materials and the scrapping of mechanical equipment. Lubrication technology is an effective means to reduce friction and wear. An important means of lubrication technology is to use lubricants. Lubricants can be divided into liquid lubricants and solid lubricants, which are attached or coated on the surface of the friction pair to form a lubricating transfer film on the friction surface through the friction and wear process to improve the contact between the friction pair conditions, thereby playing an effective role in reducing wear and tear. [0003] Some existing anti-friction materials have poor anti-friction and lubrication effects, and cannot meet the anti-friction requirements of extreme environments such as high temperature, high pressure or corrosion. Contents of the invention [0004] The te...
