Problems solved by technology

[0003] 1. Existing industrial gear oils generally have insufficient extreme pressure and anti-wear performance, and the working surface of the gear device is greatly worn;
[0004] 2. The working temperature of gear oil is relatively wide. In contact with air, metal, impurities, etc., gear oil at high temperature is prone to oxidation, resulting in increased oil viscosity, increased acid value, and decreased surface tension, thereby causing metal corrosion ;
[0005] 3. The polar additives in the gear oil are easy to react with some alloy parts in the gear device, causing corrosion of the parts;
[0006] 4. Insufficient thermal stability, some additives in gear oil are easy to precipitate when stored at low temperature, and additives may react with each other at high temperature to form precipitation, reducing the performance

Abstract

The invention discloses a totally-synthesized over-load antiwear extreme-pressure industrial gear oil and a preparation method thereof. The totally-synthesized over-load antiwear extreme-pressure industrial gear oil comprises synthetic base oil, a sulfur-phosphorus-free organo-molybdenum friction-reducing agent, a borate anti-wear reagent at extreme pressure, an anti-oxidation and anti-gum inhibitor, a viscosity index improver, a pour-point depressant, a friction improver and an anti-rust agent, wherein the synthetic base oil is base oil IV. The totally-synthesized over-load antiwear extreme-pressure industrial gear oil has excellent extreme-pressure antiwear properties, heat stability, anti-rust capability and corrosion resistance, meets demands for starting at high and low temperature and for heavy loads of equipment and prolongs the service life of the gears and bearings of the equipment; meanwhile, the sulfur-phosphorus-free organo-molybdenum friction-reducing agent and the borate anti-wear reagent at extreme pressure produce synergism, so the friction coefficient of a contact surface is reduced, the gear oil has improved capability in withstanding extreme pressure and over-load, and protruding antiwear and antifriction effects are exerted on the surfaces of gears and bearing parts.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a fully synthetic super-load anti-wear extreme pressure industrial gear oil. Background technique [0002] Gears are the most widely used transmission parts in modern machinery and equipment. With the development of science and technology, the load-carrying capacity of gears is getting bigger and bigger, the speed is getting higher and higher, the friction between the tooth surfaces is getting bigger and bigger, and the oil temperature during work Elevation accelerates the friction and wear of the tooth surface of the gear, and even the gluing fails. Therefore, the lubrication of gears is particularly important. Especially heavy-duty mechanical equipment such as machinery, metallurgy, and mining are mostly heavy-duty, low-to-medium speed, and frequently started, subject to impact loads, requiring lubricating oil suitable for high temperature and high load. This requires...
