Novel extreme pressure lubricating oil

Abstract

The invention discloses a novel extreme pressure lubricating oil which is prepared from the following raw materials in parts by weight: 1.5-4.1 parts of nano titanium dioxide, 2.3-4.4 parts of hydrogenated dimer acid, 25-33 parts of industrial red oil, 2.5-7.1 parts of FEVE (fluoroethylene vinyl ether) fluorocarbon resin, 2.5-4.5 parts of sorbitan monooleate, 10-17 parts of glycerol and 3.5-4.7 parts of acrylate-modified butadiene resin. According to the novel extreme pressure lubricating oil, the carrying capacity of gear grease is greatly improved, the influence of a conventional lead-containing formula on health of operators is avoided, and the surfaces of steel and copper parts can be effectively prevented from being worn; due to proper adhesion and low friction coefficient, the noise generated during operation of gears and the machine body temperature can be effectively reduced and the energy consumption can be decreased; the service life of an oil product can be greatly prolonged, the oil change frequency can be reduced and the enterprise cost can be saved under the conditions that various properties are excellent and the normal operation of a steam turbine is guaranteed.

Description

technical field [0001] The invention relates to a novel extreme pressure lubricating oil, which belongs to the field of industrial chemical industry. Background technique [0002] The existing gear grease generally uses mineral oil as the base oil, and various additives are added, such as detergent and dispersant, anti-oxidant and anti-corrosion agent, demulsifier, anti-foaming agent, oily agent and extreme pressure anti-wear agent. Since gears are under heavy loads during operation, good extreme pressure and anti-wear performance is an important criterion for evaluating the quality of gear greases. Traditional extreme pressure antiwear agents are mainly sulfur-containing and phosphorus-containing. It is difficult to achieve a suitable balance between the extreme pressure and antiwear properties and high temperature stability of such compounds. At the same time, it has a negative impact on the anti-emulsification of the gear, which will reduce the strength of the oil film a...

Problems solved by technology

However, the existing new technology, such as the use of nano-diamond powder in the patent CN101029264, is prepared by the negative oxygen balance method and functional group modification method. The steps are cumbersome and expensive, which is not conducive to large-scale industrial production, and its Trinitrotoluene used in the production process is extremely explosive and poses a great safety hazard
