The esters is one or more of NP343, NP372 and P81, the hydrocarbon is one or more of PA08, PA010 and PA012, the three-type base oil is one or more of 150NN, 100N, 75N and 250N, the extreme pressure antiwear agent is one or more of T323, T321 and T306, the cleaning agent is one or more of T101, T104 and T105, the oxidation and corrosion inhibitor is one or two of T203 and T204, and the anti-friction agent is boron nitrogen compound. The invention has excellent high temperature stability, antioxidation stability, wear-resistance, corrosion resistance and rust resistance. The gear lubricant is added into various gear oil according to the proportion, the viscosity or the viscosity index of the gear oil is slightly changed or not changed, so that the wear resistant, high temperature resistant and press resistant boundary lubricating oil film is formed rapidly when an apparatus is at high speed, low speed, heavy load or impact load.
Description
Technical field
The invention belongs to field of lubricant, particularly a kind of new gear lubricant and preparation method thereof.
Background technology
The classification of lubricant has: solid lubricant, liquid lubricant, gas lubricant and semi-solid lubricants.Although so lubricant of multiple types is arranged, because the difference of the kind of equipment, structure, operation conditions, so the lubricating system of equipment is also different with the requirement to lubricant.Especially once be considered as all kinds of geared machines lubricated of industrialization symbol, it not only needs lubricating oil to have good sticking warm nature, can still can keep enough oil-bound films under the gear tooth friction hot conditions, the unlikely wearing and tearing.And when low temperature, also to have enough flowabilities, there are enough gear oils flank of tooth lubricant housings, prevents from starting wearing and tearing.This is a very formidable lubricated difficult problem always.
At present, various geartransmission equipment lubricated, the gear lubricating oil product of use all can only satisfy equipment component lubrication needs under general condition.How to guarantee that gear can effectively lubricating in high extreme pressure interlock transmission or extreme pressure grind, can reduce the resistance of motion again and reach save energy, be the lubricated very scabrous problem of industry always.
Summary of the invention
The object of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of and can under low viscosity, high extreme pressure boundary lubrication condition, guarantee the effectively lubricating of all kinds of geartransmission equipment, effectively the gear lubricant of capable of reducing friction resistance, reduction wearing and tearing.
The present invention is achieved by the following technical solutions:
A kind of gear lubricant is made by the raw material of following weight part: base oil: ester class 5-15, hydro carbons 30-50, three class base oil 30-40, additive: extreme pressure anti-wear additives 3-10, clear agent agent 2-4, oxidation and corrosion inhibitor 4-6, low friction compound 3-8.
The ester class is one or more among NP343, NP372 and the P81, hydro carbons is one or more among PAO8, PAO10 and the PAO12, three class oil are one or more among 150NN, 100N, 75N and the 250N, extreme pressure anti-wear additives is one or more among T323, T321, the T306, purification agent is one or more among T101, T104 and the T105, oxidation and corrosion inhibitor is one or both among T203 and the T204, and low friction compound is boron-nitrogen compound.
The ester class is NP343, and hydro carbons is PAO12, and three class oil are 150N, and extreme pressure anti-wear additives is T323, and purification agent is T101, and oxidation and corrosion inhibitor is T203, and low friction compound is boron-nitrogen compound.
Raw material by following weight part is made
Base oil: ester class 10, hydro carbons 32, three class base oils 35,
Additive: extreme pressure anti-wear additives 8, purification agent 4., oxidation and corrosion inhibitor 4, low friction compound 7.
The preparation method of gear lubricant may further comprise the steps:
A, by above-mentioned weight part ester class, hydro carbons and three class base oils are joined in the container, be heated to 50 ℃-90 ℃, mixed 50-70 minute;
B, add successively extreme pressure anti-wear additives, purification agent, oxidation and corrosion inhibitor and low friction compound in the container of A step by weight and mix, be 10-15 minute pitch time that adds every kind of raw material, and raw material all added Hybrid Heating 30-40 minute afterwards;
C, step B products obtained therefrom is down to normal temperature, filters packing.
Described step is heated to 70 ℃, mixes 60 minutes, and described step B pitch time is 12 minutes, and Hybrid Heating was 35 minutes after raw material all added.
Advantage of the present invention is:
Product has excellent high-temperature stability, anti-oxidative stability and wear-resistant, anti-corruption and rustless property.Its modest viscosity, the ratio in 5% add in all kinds of gear oils, and be minimum or can not change gear oil viscosity or viscosity index.Condensation point to typical gear oil has auxiliary pour-point depressing process.Can make equipment under high speed, low speed, heavy duty or impact load, form rapidly a kind of borderline oil film of wear-resisting, high temperature resistant, anti-extruding, guarantee good oilness.Prevent the breakoff phenomenons such as the flank of tooth weares and teares, scratch, gummed, make wheelwork be able to permanently effective operation.The work-ing life of extension device.Save energy.
