Novel gear extreme pressure grease

Abstract

The invention discloses a novel gear extreme pressure grease, which is prepared from the following raw materials by weight: 1.5-4.1 parts of dimethyl-dithio-dipropyl amide, 2.3-4.4 parts of hydrogenated dimeric acid, 25-33 parts of industrial red oil, 2.5-7.1 parts of 2-amino-2-methyl-1-propyl alcohol, 2.5-4.5 parts of sorbitan monooleate, 10-17 parts of glycerol and 3.5-4.7 parts of boric acid. The invention can greatly improve bearing capacity of the gear grease but also eliminate the influences of a traditional lead formula on the health of workers and can effectively prevent wearing on the surfaces of steel and copper parts; proper adhesion and extremely low coefficient of friction can effectively reduce the noise produced during gear running and machine temperature and reduce energy consumption; and in the premise of excellent performance and ensuring normal operation of a steam turbine, the novel gear extreme pressure grease greatly prolongs the service life of oil, reduces the oil change frequency and saves cost for enterprises.

Description

technical field [0001] The invention relates to a novel gear extreme pressure lubricating grease, 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 oi...

Problems solved by technology

However, the existing new technology, such as patent CN101029264, uses nano-diamond powder. The nano-material is prepared by 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
