Example Embodiment

[0019] Example 1: Graphite or molybdenum disulfide with a particle size of 3-10 μm was sprayed with monoalkoxy tris(dioctylphosphoryloxy) titanate, and then vacuum-baked at 140° C. for 4 hours to make the The titanate end groups are reacted and coupled with groups such as hydroxyl groups on the surface of graphite or molybdenum disulfide; for graphene oxide with a thickness of less than 1nm and a diameter of 100nm-1μm, vacuum bake at 80 °C for 4 hours to remove surface water; use γ-aminopropyl The carbon fibers with a width of 7 μm and an aspect ratio of 7 were sprayed with triethoxysilane, and milled on a planetary ball mill for 2 hours to promote the coupling and dehydration reaction between the silane end groups and the surface groups of the carbon fibers. Bake in vacuum for 4 hours; for rutile-type TiO with a particle size of 20-100nm 2 The particles were baked in vacuum at 140 °C for 4 h to remove moisture. Take 15 parts of treated graphite, 0.05 parts of graphene oxide,...

Example Embodiment

[0020] Embodiment 2: The same parts of this embodiment and embodiment 1 will not be repeated, the difference is to take 10 parts of treated graphite, 5 parts of molybdenum disulfide, 0.1 part of graphene oxide, 0.5 part of carbon fiber, TiO 2 1 part of particles, 40 parts of polyamide-imide resin with a mass concentration of 30%, 0.4 part of polypropylene glycol modified polysiloxane with molecular weight of 500-800, and 0.4 part of double-effect active polysiloxane were added to the planetary ball mill High-speed grinding for 40 minutes, and then filtered with a 100-mesh filter to obtain a friction-reducing and anti-wear solid lubricant.

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...
