[0016] Nanoscale gear surface coating of the present invention is made up of following components by weight fraction proportioning:

[0017] Proportion by weight fraction is made from the following components:

[0018] 32 parts of graphite oxide, 54 parts of rosin resin, 4 parts of surfactant, 43 parts of oxidized castor oil, 6 parts of AMP dispersant, 44 parts of vinyl chloride copolymer resin, 6 parts of viscosity increasing agent, 15 parts of CAB resin liquid, nitriding 11 parts of boron, 15 parts of talc powder, 2 parts of molybdenum disulfide powder, 5 parts of fumed silica, 34 parts of deionized water, 3 parts of carbon black, and 6 parts of defoamer.

Embodiment 2

[0020] Nanoscale gear surface coating of the present invention is made up of following components by weight fraction proportioning:

[0021] 41 parts of graphite oxide, 76 parts of rosin resin, 8 parts of surfactant, 54 parts of oxidized castor oil, 8 parts of AMP dispersant, 48 parts of vinyl chloride copolymer resin, 9 parts of viscosity increasing agent, 17 parts of CAB resin liquid, nitriding 15 parts of boron, 31 parts of talc powder, 6 parts of molybdenum disulfide powder, 11 parts of fumed silica, 53 parts of deionized water, 6 parts of carbon black, and 11 parts of defoamer.

Embodiment 3

[0023] Nanoscale gear surface coating of the present invention is made up of following components by weight fraction proportioning:

[0024] 36 parts of graphite oxide, 65 parts of rosin resin, 6 parts of surfactant, 49 parts of oxidized castor oil, 7 parts of AMP dispersant, 46 parts of vinyl chloride copolymer resin, 8 parts of viscosity increasing agent, 16 parts of CAB resin liquid, nitriding 13 parts of boron, 23 parts of talc powder, 4 parts of molybdenum disulfide powder, 8 parts of fumed silica, 43 parts of deionized water, 5 parts of carbon black, and 8 parts of defoamer.

[0025] The graphite lubricating coating for gears of the present invention has stable colloidal form and reliable stability, and can replace traditional gear lubricants, such as butter. Using graphite oxide has more lubricity than graphite lubricants. At the same time, the coating has good thermal stability through ingenious doping of boron nitride and molybdenum disulfide powder.

Abstract

The invention relates to a nano-scale gear surface coating. The nano-scale gear surface coating is prepared from the following components in parts by weight: 32 to 41 parts of graphite oxide, 54 to 76parts of rosin resin, 4 to 8 parts of a surfactant, 43 to 54 parts of oxidized castor oil, 6 to 8 parts of an AMP dispersant, 44 to 48 parts of chlorinated vinegar copolymer resin, 6 to 9 parts of aviscosity additive, 15 to 17 parts of CAB resin solution, 11 to 15 parts of boron nitride, 15 to 31 parts of talcum powder, 2 to 6 parts of molybdenum disulfide powder, 5 to 11 parts of aerosil , 34 to 53 parts of deionized water, 3 to 6 parts of carbon black, 6 to 11 parts of a defoaming agent. The nano-scale gear surface coating provided by the invention has the advantages that the nano-scale gear surface coating be made into nanoscale fineness through the selection and cooperation of raw materials, while gear parts are effectively prevented from being corroded, the gear performance of gearparts is minimized.

Description

technical field [0001] The invention relates to the field of gear protection, in particular to a nanoscale gear surface coating. Background technique [0002] Gear coating refers to the coating applied on the surface of the gear. Gear coatings have the following properties: [0003] (1) Hiding power: Hiding power is usually expressed by the weight of the paint required to cover the specified black and white grid. The greater the weight, the smaller the hiding power. [0004] (2) Smear adhesion: Indicates the adhesion between the coating film and the base layer. [0005] (3) Viscosity: The size of the viscosity affects the construction performance, and different construction methods require different viscosities of the paint. [0006] (4) Fineness: The fineness directly affects the smoothness and gloss of the coating film surface. [0007] The main function of existing gear coatings is to prevent the gear parts from being isolated from the outside world, and avoid the gea...
