Extreme-pressure anti-wear lubricating agent

Abstract

The invention provides an extreme-pressure anti-wear lubricating agent, and relates to the technical field of high-temperature lubricating agents. The extreme-pressure anti-wear lubricating agent comprises components in weight ratio as follows: 0.1%-3% of a component A, 8%-35% of a component B, 2%-6% of a component C, 0.5%-5% of a component D, 0.5%-4% of a component E, 0.5%-4% of a component F, 0.8%-4% of a component G, 0.2%-1% of a component H and the balance of water, wherein the component A is one of or a mixture of sodium carboxymethylcellulose and xanthan gum; the component B is one of or a mixture of talc powder and bentonite; the component C adopts sodium silicate; the component D adopts one of or a mixture of two or three of sodium fluoborate, borax decahydrate and calcium metaborate; the component E adopts one of zinc stearate and lithium stearate; the component F adopts one of nano fullerene and alkaline sulfonate; the component G adopts sodium polyacrylate; and the component H adopts a water-based defoaming agent. The high-temperature friction coefficient value is very low, the lubricating property is excellent, and the lubricating requirement of current equipment under the high-temperature and high-load conditions can be well met.

Description

technical field [0001] The invention relates to the technical field of industrial lubricants, in particular to an extreme pressure anti-wear lubricant. Background technique [0002] With the development of modern machinery and equipment in the direction of high speed, high load, high temperature, etc., the lubrication conditions of the equipment have become more and more harsh; It will generate extremely high heat, the film formed by traditional lubricants will be destroyed, and it will no longer protect the metal surface, and the contact surface will be scratched or even sintered. At this time, a high temperature resistant and extreme pressure resistant lubricant is required. Lubricant to improve the wear resistance of various parts. [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 ...

Problems solved by technology

[0003] Chinese invention patent 200910053842.2 discloses an environment-friendly high-temperature lubricant for metal thermoplastic processing. Its raw materials are 20-70% of alkali metal salt, 5-50% of phosphate, 0.5-30% boric acid, 0.01-2% bactericide, and then add 1-20 times the weight of water to process it. Although this environmental-friendly high-temperature lubricant for metal thermoplastic processing has a good lubricating effect, but with the development of science and technology , the speed of the equipment is getting higher and higher, and the load on the moving parts of the machine is getting higher and higher. The above-mentioned environmentally friendly high-temperature lubricants for metal thermoplastic processing have exposed the following shortcomings: 1. The high-temperature friction coefficient value is relatively high, and its high-temperature lubrication performance needs to be strengthened

2. The maximum extreme pressure value that the lubricant can withstand is low, and it is difficult to meet the current requirements for high-load lubrication of equipment
