Epoxy resin solid lubrication coating material and preparation method thereof

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...
