Abstract
The invention discloses a gear lubricant, which is made by the following raw materials in parts by weight: 2.5-4.3 parts of sorbitan monooleate, 1.5-2.2 parts of nitrobenzoic acid, 15-25 parts of Turkey oil, 2.5-4.1 parts of diethanolamine borate, 1.5-2.2 parts of dodecanedioic acid and 3-6 parts of triethanolamine. The gear lubricant composition has excellent viscosity temperature properties and high viscosity index, so as to ensure that the lubricant still has the proper viscosity, oil film thickness and low solidifying point when the lubricant is used in the relatively wide temperature range, and the lubricant still has good fluidity at low temperature, and furthermore the lubricant is conveniently pumped or carried to a lubrication point. The safety index of use of the lubricant products is ensured, the transportation, storage and use of the lubricant products are facilitated. The ordinary gear lubricant emulsifies due to a small amount of water into the gear lubricant, so that the lubricant film is broken and invalid. When 20% of water enters into the synthetic gear lubricant provided by the invention, the gear lubricant still has good lubricity.
Description
Technical field
The present invention relates to a kind of gear grease, belong to industrial chemical field.
Background technology
Gear oil is to take mineral base oil or synthetic base oil as main, a kind of important lubricating oil that adds extreme pressure anti-wear additives and oiliness improver modulation to form, for various wheel gearings, to prevent tooth surface abrasion, scratch, sintering etc., extend its work-ing life, improve transmitted power efficiency, reduce power loss.Gear oil should have good wear-resistant, withstand load performance and suitable viscosity.In addition,, even if also should there is good thermal oxidation stability, anti-bubble, water separable performance energy and rustless property synthetic gear oil under very high service temperature and load, still can guarantee that all parts of transmission system is not frayed.In industrial production, often because poor sealing causes water coolant seepage in oiling system, cause emulsification of lubricant rotten, stop up oil circuit, be forced to more oil change and produce normal operation with assurance.Existing gear oil addresses this problem the method for the system water inlet raising demulsibilities that adopt more, or oil product is changed.Although improve demulsibility, can solve temporarily the impact of water inlet on gear oil, the additive in gear oil usually reduces gradually along with the separation of water.The existence of a small amount of moisture still easily causes lubrication failure, directly gear oil is changed to the use cost that has increased again enterprise.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of gear grease is provided, and has excellent viscosity temperature characteristic, high viscosity index guarantees that oil product is used and still has suitable viscosity and oil film thickness in wide temperature range.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of gear grease is made by the raw material of following parts by weight:
Sorbitan monooleate 2.5-4.3 part, nitrobenzoic acid 1.5-2.2 Fen, Turkey oil 15-25 part, diethanolamine boric acid ester 2.5-4.1 part, SL-AH 1.5-2.2 part and trolamine 3-6 part.
Optimize, said gear lubricating oil, by the raw material of following parts by weight, made:
4 parts of 18 parts of 3 parts of sorbitan monooleates, nitrobenzoic acid 2.1Fen, Turkey oil, 3.5 parts of diethanolamine boric acid esters, 1.8 parts of SL-AH and trolamines.
The invention provides lubricant for gears composition and there is excellent viscosity temperature characteristic, high viscosity index, assurance oil product is used in wide temperature range still has suitable viscosity and oil film thickness, low condensation point, guarantee that oil product still has good mobility at lower temperature, be beneficial to pumping or be carried into oiling point, guarantee the safety indexes that oil product is used, be conducive to the transportation of oil product, store and use, ordinary gear oil enters a small amount of water can there is emulsification, thereby cause oil-bound film fracture failure, synthetic gear oil provided by the invention is when the water that enters 20%, still have good oilness.
Embodiment
embodiment 1
The present invention is a kind of gear grease, by the raw material of following parts by weight, is made:
4 parts of 18 parts of 3 parts of sorbitan monooleates, nitrobenzoic acid 2.1Fen, Turkey oil, 3.5 parts of diethanolamine boric acid esters, 1.8 parts of SL-AH and trolamines.
embodiment 2
The present invention is a kind of gear grease, by the raw material of following parts by weight, is made:
3 parts of 15 parts of 2.5 parts of sorbitan monooleates, nitrobenzoic acid 1.5Fen, Turkey oil, 2.5 parts of diethanolamine boric acid esters, 1.5 parts of SL-AH and trolamines.
embodiment 3
The present invention is a kind of gear grease, by the raw material of following parts by weight, is made:
6 parts of 25 parts of 4.3 parts of sorbitan monooleates, nitrobenzoic acid 2.2Fen, Turkey oil, 4.1 parts of diethanolamine boric acid esters, 2.2 parts of SL-AH and trolamines.
The invention provides lubricant for gears composition and there is excellent viscosity temperature characteristic, high viscosity index, assurance oil product is used in wide temperature range still has suitable viscosity and oil film thickness, low condensation point, guarantee that oil product still has good mobility at lower temperature, be beneficial to pumping or be carried into oiling point, guarantee the safety indexes that oil product is used, be conducive to the transportation of oil product, store and use, ordinary gear oil enters a small amount of water can there is emulsification, thereby cause oil-bound film fracture failure, synthetic gear oil provided by the invention is when the water that enters 20%, still have good oilness.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement, all should belong to protection scope of the present invention.
