Problems solved by technology

The anti-stick and wear-resistant coatings described in Chinese patent ZL98126804.8 have long life and low coefficient of friction, but the coating has low load-bearing capacity, poor resistance to hydraulic and lubricating oil media, and poor high temperature resistance.
Its coating cannot be widely used in harsh working conditions such as high load, high speed, high temperature, hydraulic pressure and lubricating oil medium, and the coating film thickness construction process is poor, and the coating film thickness is difficult to control
Oil-resistant, high-temperature-resistant, wear-resistant lubricating coatings with excellent comprehensive properties that cannot widely meet the needs of the civil market

Abstract

The invention discloses a machine oil resistant, high temperature resistant, and grinding resistant lubricating coating material. It is made up of binding agent, solid lubricant, mix solvent, and assistant agent. The binding agent adopts poly-phenylene thioether resin; solid lubricant adopts polytetrafluoroethylene, mix solvent is the mixture of distilled water and ethanol; assistant agent adopts cyanuric ammonia and cyanuric acid ester complex, antimony trioxide, and rare earth fluoride. It has the advantages of super high bearing capacity, good adaptability to hydraulic pressure and lubricant medium, high temperature resistant, long useful life, etc.

Description

technical field [0001] The invention describes an oil-resistant, high-temperature-resistant, wear-resistant lubricating coating and a preparation method thereof. Background technique [0002] Due to the high load, high speed, dry friction and long-term immersion in oil medium, the temperature rise of the surface of the components is relatively high due to the dry friction of the machinery, chemical industry, metallurgy and other industries, as well as the high-load cylinder piston and sliding parts under the action of hydraulic and lubricating oil media. If the temperature is too high, the parts will be sintered and strained, so that the parts will fail, so that the working life of the equipment will be shortened, the energy consumption of the equipment will increase, and the economic cost will be too high. If a layer of environmentally friendly medium-resistant, high-temperature-resistant, and wear-resistant lubricating paint is applied to the friction parts, it will not on...
