Abstract

The invention provides an extreme-pressure lubricant, and relates to the technical field of industrial lubricants. The extreme-pressure lubricant is prepared from, by weight, 2.5% of component A, 28% of component B, 5% of component C, 7% of component D, 2% of component E, 4.5% of component F, 0.8% of component G and the balance water. The component A is polyvinyl alcohol, the component B is talcum powder, the component C is sodium silicate, the component D is sodium fluoborate, the component E is zinc stearate, the component F is water-soluble zinc dialkyl dithiophosphate or water-soluble fullerene-styrene-acrylic copolymer nanoparticles with the diameter of 10-15 nanometers, and the component G is a water-based defoaming agent. The extreme-pressure lubricant is extreme low in high-temperature friction coefficient, excellent in lubricating performance and capable of meeting the lubricating requirement of equipment under high-temperature and high-load conditions well at present.

Description

technical field [0001] The invention relates to the technical field of industrial lubricants, in particular to an extreme pressure lubricant. Background technique [0002] With the development of modern mechanical equipment in the direction of high speed, high load, high temperature, etc., the lubrication conditions of the equipment become more and more harsh; when the mechanical equipment is under high load and high speed conditions, the film formed by traditional lubricants will If it is damaged, it will no longer protect the metal surface, and the contact surface will be scratched or even sintered. At this time, an extreme pressure-resistant lubricant is needed to improve the wear resistance of each component. [0003] Chinese invention patent 200910053842.2 discloses an environment-friendly high-temperature lubricant for metal thermoplastic processing. 1 to 20 times the weight of water, although the environment-friendly high-temperature lubricant for metal thermoplastic...
