Example Embodiment

[0028] Example one:

[0029] 1. Add 460ml of 98% concentrated sulfuric acid into a three-necked flask, cool to 0~6℃, add 20g colloidal graphite powder with a particle size of 2μm under stirring, then weigh 30g potassium permanganate and slowly add it to the flask After reacting for 2h, heat to 35℃, continue the reaction for 30min, slowly add 460ml deionized water to the system, continue stirring for 15min, transfer the product to a large beaker, dilute with 2500ml deionized water and add a concentration of 5% 200ml of hydrogen peroxide containing 200ml, stand still, pour off the supernatant, filter and wash repeatedly until the filtrate has no sulfate residues, dry, grind, and sieve to obtain graphite oxide for use. (This graphite oxide preparation method is slightly improved on the basis of the Hummers method. The original Hummers method is from the reference: Willams Hummers, JR Richarde Offeman. Preparation of Graphitic Oxide. Journal of the American Chemical Society [J]. 1958...

Abstract

The invention relates to an epoxy resin solid lubrication coating material containing surface finish graphite oxide and a preparation method thereof. The material is a coating material containing a component A and a component B, and is characterized in that: the component B is a curing agent, and the weight of the component B is 3-15% of that of the component A; the component A comprises the following components by weight percentage: 20-35% of solid lubricant, 25-45% of epoxy resin, 1-5% of coupling agent and 25-55% of organic solvent. The invention provides a method and an approach for preparing a polymolecularity and macromolecule based nanocomposite and a macromolecular resin based solid-film lubricantion coating material, solves the problems of poor dispersity of the graphite solid lubricant in a resin solution, and solves the difficult problems that the macromolecular resin based solid-film lubricantion coating material has uneven concentration and harder thickness control, defects of the coating and the like.

Description

technical field [0001] The invention relates to a solid lubricating coating material and a preparation method thereof, in particular to an epoxy resin solid lubricating coating material containing surface-modified graphite oxide and a preparation method thereof. Background technique [0002] Under the harsh working conditions of ultra-high temperature, low speed and high load, solid lubrication technology can ensure long-term and effective lubrication of workpieces, and has been widely used in aviation, aerospace and weapon systems and other fields. Polymer resin-based solid lubricating coating uses polymer resin as the binding phase, disperses graphite and molybdenum disulfide as solid lubricants in the resin, and coats it on the surface of mechanical transmission friction components through a specific coating process , to reduce the friction coefficient and wear of the friction pair. The polymer resin-based solid lubricating coating not only has a lower friction coefficie...
