Abstract

The invention relates to a friction-reduction and antiwear solid lubrication material and a preparation method thereof. The method includes: firstly pretreating friction-reduction and antiwear materials composing the solid lubrication material, taking 6-15 parts of treated graphite and / or molybdenum disulfide, 0.05-0.1 part of treated graphene oxide, 1-5 parts of treated carbon fiber, 0.1-1 part of treated TiO2 particle, 30-70 parts of treated polyamideimide resin with a mass concentration of 30%, 0.1-0.8 part of treated polypropylene glycol modified polysiloxane with a molecular weight of 500-800, and 0.1-0.8 part of treated double-effect active polysiloxane, adding the materials into a planetary ball mill to conduct high speed grinding for 40min to promote reaction of the surface functional groups each particle with the isocyanate or amide group in the polyamideimide resin so as to form a covalent bond or secondary bond, and then carrying out filtering with a 100mesh filter screen, thus obtaining the friction-reduction and antiwear solid lubrication material.

Description

technical field [0001] The invention relates to a friction-reducing and anti-wear solid lubricating material and a preparation method thereof. Background technique [0002] Friction is a phenomenon caused by the relative motion of objects, and it is a major way of energy loss. It is estimated that 1 / 3-1 / 2 of the world's energy is eventually consumed by various forms of friction. [0003] Therefore, using lubrication to overcome the energy loss caused by friction is a major way to solve and alleviate the energy shortage. At present, in various fields of the national economy, such as aerospace, transportation, heavy machinery, military industry, etc., different forms of liquid lubrication or solid lubrication are used to solve friction problems. [0004] Compared with liquid lubrication, solid lubrication has the characteristics of continuous use at high temperature. The solid lubricating coating of metal, ceramic or polymer composite is formed on the dual surface of the fr...
