Anti-wear, anti-friction and anti-oxidant additive and energy-saving hydraulic oil containing same

Abstract

The invention discloses an anti-wear, anti-friction and anti-oxidant additive and energy-saving hydraulic oil containing the same. Zinc dialkyl thiosulfate, molybdenum phosphate, molybdenum dithiocarbamate, a boron nitrogen compound, borate, organic molybdenum, methylene bisdibutyl dithiocarbamate, polyisobutylene dibutyl diimide, 350N paraffin base oil, polyalphaolefin PAO8 and polyol ester are used as raw materials, and the specific gravity of each component is strictly controlled; the borate has good anti-wear performance, so that the service life of a machine can be prolonged by more thanone time, the bearing capacity is strong, and a sintering accident can be prevented; the friction coefficient is low, and the friction coefficient of oil prepared from a borate agent can be as low as0.05-0.06 at a room temperature; most of the conventional lubricating oil uses an oil-soluble liquid anti-wear agent, and solid anti-wear agents such as graphite, molybdenum disulfide and polytetrafluoroethylene can be applied only when particles thereof are small and stably dispersed in base oil of the lubricating oil; the anti-wear, anti-friction and anti-oxidant additive has very good anti-wearand friction-reducing effects.

Description

technical field [0001] The invention relates to the technical field of anti-wear, anti-friction, and anti-oxidation additives, in particular to an anti-wear, anti-friction, and anti-oxidation additive and energy-saving hydraulic oil containing the additive. Background technique [0002] The energy consumption loss of the hydraulic system is mainly reflected in the following aspects: throttling loss, overflow loss, internal leakage, local pressure loss, loss along the way, fluid compression and expansion loss, mechanical friction loss, etc. Oil solves the energy consumption problem of the hydraulic system from a single aspect. There is no analysis and solution from the perspective of the entire hydraulic system. For example, the hydraulic oil blended with mineral oil mainly shrinks the sealing ring of the hydraulic system, while the fully synthetic hydraulic oil mainly expands the sealing ring; the anti-wear agent is mainly liquid, and the liquid is anti-wear In the process...

AI Technical Summary

Problems solved by technology

For example, the hydraulic oil blended with mineral oil mainly shrinks the sealing ring of the hydraulic system, while the fully synthetic hydraulic oil mainly expands the sealing ring; the anti-wear agent is mainly liquid, and the liquid is anti-wear In the process of functioning, the agent chemically reacts with the metal on the surface of the friction pair to form a new metal compound to play the role of anti-wear and anti-friction, that is to say, the metal friction pair is continuously consumed during the working process; secondly, it is produced with mineral oil The loss along the process of hydraulic oil during use is much greater than that of synthetic oil; at the same time, the viscosity of mineral oil changes much more than that of synthetic oil with the change of temperature. High, when the temperature is high, the viscosity becomes smaller, resulting in throttling, large internal leakage, and the thinning of the lubricating oil film, making it difficult to separate the two friction pairs and reduce friction. Now there is a lack of an anti-wear, anti-friction and anti-oxidant additive and containing The energy-saving hydraulic oil of the additive to comprehensively solve the above problems
