Abstract
Disclosed anti-oxidation gear oil is prepared from the following raw materials in parts by weight: 15-22 parts of sodium lauryl polyoxyethylene ether sulfate, 10-17 parts of mineral mixed oil, 2.5-7.3 parts of maleic anhydride, 2.3-6.5 parts of triethanolamineoleate, 2.3-4.6 parts of hendecanedioic acid and 1.2-6.3 parts of potassium borate. Compared with conventional gear oil, the anti-oxidation gear oil has the characteristics of being good in anti-oxidation anti-corrosion property and antirust property, long in oil changing period, capable of reducing discharge of waste oil, exhaust gas and particles, good in biodegradability, relatively low in price compared with conventional lubricating oil; also the anti-oxidation gear oil helps heavy-load industrial gear with high-speed, low-speed, heavy-duty, high-torque or impact load to form a wear-resistant high-temperature-resistant extrusion-resistant boundary lubricating oil film, helps to prevent gear surface from wearing, scratching, gumming, pitting and the like, and helps to prolong the service life of the heavy-load industrial gear.
Description
Technical field
The present invention relates to a kind of anti-oxidant gear oil, belong to industrial chemical field.
Background technology
At present, external gear type oil pump both domestic and external is high pressure gear oil pump particularly, mostly adopt cast housing and DU bearing arrangement, the DU bearing of supporting principal and subordinate gear shaft neck is to determine toothed gear pump rated pressure and the vitals in life-span, but the sealing means due to the end play auto-compensation adopting, all take high-pressure oil is thoroughly isolated to low pressure casing bearing chamber as main, even if novel DU bearing (carbon steel base toothed gear pump self-oiling bearing) is under the condition of oil lubrication, the highest PV value reaches 60N/mm2m/s, maximum line velocity V reaches 10m/s, also because lubricants capacity is inadequate, the performance of DU bearing is not fully utilized, make bearing ablation and destroy or reduce work-ing life, cause high-pressure gear pump short work-ing life.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of anti-oxidant gear oil is provided, and has good anti-oxidation and antisepsis, rust-preventing characteristic, drain period is long, reduce waste oil, waste gas and granular material discharged, biodegradability good, with low cost.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of anti-oxidant gear oil is made by the raw material of following parts by weight:
Alkylpolyoxyethylene sodium sulfate 15-22 part, mineral mixing oil 10-17 part, MALEIC ANHYDRIDE 2.5-7.3 part, triethanolamine oleate 2.3-6.5 part, ten carbon dicarboxylic acid 2.3-4.6 parts, potassium borate 1.2-6.3 part.
Optimize, above-mentioned anti-oxidant gear oil, by the raw material of following parts by weight, made:
17 parts, alkylpolyoxyethylene sodium sulfate, 12 parts of mineral mixing oils, 5.3 parts of MALEIC ANHYDRIDE, 4.6 parts of triethanolamine oleates, 3.3 parts of ten carbon dicarboxylic acids, 5.6 parts of potassium borates.
The present invention compares with existing gear oil, have good anti-oxidation and antisepsis, rust-preventing characteristic, wear-resistant, antifriction, carrying, high moment of torsion, preservative property, high-temperature stability, resistance to emulsion, drain period long, reduce waste oil, waste gas with granular material discharged, biodegradability good, the lower feature of the relative conventional lubrication oil of price; Simultaneously, can make heavy loading industrial gear under high speed, low speed, heavy duty, high moment of torsion or impact load, form rapidly borderline oil film wear-resisting, high temperature resistant, resistance to extruding, prevent the breakoff phenomenons such as the flank of tooth weares and teares, scratch, gummed, spot corrosion, to extend the work-ing life of heavy loading industrial gear.
Embodiment
