Description
Technical field
The present invention relates to a kind of vehicle lubricating oil, particularly automotive gear oil.
Background technology
Automotive gear oil is the general name for gear of vehicle transmission system lubricating oil, and it mainly is applied to the transmitting gear of manual transmission, diverter and the front and back bridge of vehicles such as lubricated automobile, tractor, engineering machinery.Automotive gear oil is in gear drive, and main effect is to reduce friction, and reduces wearing and tearing, cooling parts; Simultaneously, also play and relax vibration, reduce and impact, prevent corrosion and the effect of cleaning the surface of friction booty.
Development along with Domestic Automotive Industry, very big variation has taken place in the vehicle arrangement performance structure: at first, because the vehicle user is to the requirement of fuel economy, the merchant of Railway Car Plant has improved back axle and wheel box transmission power density, the capacity of inner gear of the gear box oil is diminished, the gear oil cycle frequency increases, thereby causes that gear temperature and load improve rapidly.Secondly, the widespread use of aerodynamic design and airflow design, though can effectively improve fuel efficiency, but the gear tangential speed is accelerated, the gear bearing load increases, back axle and wheel box ambient air flow velocity reduce, and may make working temperature raising 25～30 ℉ of heavy loading truck manual transmission owing to employing aerodynamic design and airflow design according to the OEM report.At last, the use of snubber produces the stripping hole at the gear crown easily.This all makes the lubricating condition at system of vehicle transmission position in the past more harsh, thereby the over-all properties of automotive gear oil is had higher requirement.In addition, because synchronizer being extensive use of on novel manual wheel box and drive axle makes original gear box oil can not satisfy service requirements; Satisfy the APIGL-5 oil of MIL-L-2105D specification in actual use, a large amount of greasy filth, paint film and deposition have occurred, cause the oil product use properties to descend, sealing leak also can not have been satisfied the requirement that gear of vehicle mechanism uses in reality.Therefore, press for have the good resistance oxidation, the high performance vehicle gear oil of characteristic such as wear-resistant, rust protection, high bearing capacity.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of automotive gear oil that good sticking warm nature, thermal oxidation stability, extreme pressure property, wear resistance, anti-load, resistance to emulsion, anti-spumescence, erosion resistance, rust-preventing characteristic, stability in storage, synchronous weather resistance, sealing material consistency are arranged.
The present invention solves the problems of the technologies described above with following technical scheme:
The synthetic oil that the poly-internal olefin of employing and oil soluble polyethers are combined into cooperates multiple composite additive as the base oil of automotive gear oil, and the mass percent of its each component is:
| Component | Content (mass percent) |
| Base oil | 85%～90% |
| Oxidation inhibitor | 1.0%～4.0% |
| Extreme pressure anti-wear additives | 4.0%～6.0% |
| Rust-preventive agent | 0.02%～0.1% |
| Metal passivator | 0.8%～1.2% |
| Kilfoam | 0.05%～0.3% |
| Non-emulsifying agent | 0.2%～0.5% |
| Oiliness improver | 1.0%～3.0% |
Base oil is that poly-internal olefin and 40%～30% the oil soluble polyethers of mass ratio 60%～70% is compound.
Oxidation inhibitor is 3 of mass ratio 40%～50%, 5-di-t-butyl-4-hydroxyl phenylpropionic acid alkyl (C7-C9 branching) ester and 60%～50% compound to di-iso-octyldiphenylamine.
Extreme pressure anti-wear additives is that boronation phosphoric acid ester and 30%～40% the dialkyl group curing phosphoric acid sulfuration oxygen molybdenum of mass ratio 70%～60% is compound.
Rust-preventive agent is that low alkali value calcium alkylbenzenesulfonate and the synthetic barium sulfonate of 60%～50% high base number of mass ratio 40%～50% is compound.
Metal passivator is that thiadiazoles derivative and 40%～50% the benzotriazole derivative of mass ratio 60%～50% is compound.
Kilfoam is acrylate and ether copolymer.
Non-emulsifying agent is amine and epoxy compounds condenses.
Oiliness improver is that oleic acid ethylene glycol and 30%～40% the phosphonic acid ester of mass ratio 70%～60% is compound.
The remarkable advantage of automotive gear oil of the present invention has:
1. good combination property, every performance index all reach service requirements.It has good sticking warm nature, thermal oxidation stability, extreme pressure property, wear resistance, anti-load, resistance to emulsion, anti-spumescence, erosion resistance, rust-preventing characteristic, stability in storage, synchronous weather resistance and sealing material consistency; Guaranteed that gear of vehicle mechanism has enough oil film thicknesses under severe condition, reduced the frictional coefficient between the flank of tooth, improved the transmission efficiency of gear mechanism, effectively prolonged work-ing life and the oil draining period of gear of vehicle transmission system.
2. the oil soluble polyethers of Cai Yonging is except the advantage with traditional polyethers, and elastomer compatibility and water absorbability are significantly improved, and has overcome between traditional polyethers and other base oils to have insoluble deficiency.
Embodiment
The present invention be directed to the harsh day by day service requirements of automotive gear oil, the synthetic oil that the poly-internal olefin of employing and oil soluble polyethers are composited is as base oil; By adopting artificial neural network algorithm, targetedly to multiple functional additive screening and prediction; And adopt genetic algorithm to carry out choosing of optimization prescription, seek to obtain the gear of vehicle oil ingredient of different size, cost performance.This gear oil has good sticking warm nature, rust-preventing characteristic, thermal oxidation stability, resistance to emulsion, anti-spumescence, erosion resistance, extreme pressure property, wear resistance, stability in storage; Its every performance index all meet service requirements, are applicable to the lubricated and sealing of gear of vehicle transmission rig.
