Abstract

The invention aims to provide a water-based dispersoid solid lubricant material and the preparation method thereof; wherein, the water-based dispersoid solid lubrication material can be used as solid lubrication material, has good filming and adhesive properties, anticorrosion and wear resistance, and adopts polyamide imide and PTFE as main adhesive material; the water-based solid lubricant is environmental protection, anticorrosive and wear resistant, has low friction coefficient and good high and low temperature resistance, overcomes the problems that the organic solvent of solid lubrication material in prior art has greater toxicity, easy volatilization and is not wear resistant so that the water-based solid lubricant has good application prospect.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to an aqueous solid lubricant. Background technique [0002] The lubricating mechanism of solid lubricating materials is not like liquid and colloidal lubricating materials that form a certain form of fluid or semi-fluid film on the friction interface to achieve effective lubrication, but mainly rely on the low shear characteristics of the material itself or its transfer film. Has excellent anti-wear and anti-wear properties. As a new type of lubricating material, solid lubricating materials have greatly broken through the limits of traditional materials in terms of performance. It provides strong technical support for friction and wear problems under typical special working conditions such as media, and also lays an important foundation for improving the stability and reliability of machinery. Now its application range has shifted from aviation, aerospace and military technology to autom...
