Abstract
A composite additive of lubricating oil for both gear and worn gear is prepared from polar antiwear agent, oily agent, antirusting agent, anti-emulsifying agent and corrosion inhibitor. It serves to increase efficiency, reduce wear and cost and ellongate service life.
Description
The present invention relates to a kind of lubricating oil additive, particularly relate to a kind of industrial gear and worm gear composite additive of lubricating oil and preparation method thereof.
As everyone knows, gear is most widely used a kind of transmission mechanism in the machinery equipment in modern age, does not wait to several meters from several millimeters, can simply be divided into enclosed geartransmission, exposed gear transmission and worm and gear by the transmission type.Industrial different needs has been satisfied in various transmissions.Because gear oil is different with the performance requriements of worm and worm wheel oil, therefore gear oil and worm and worm wheel oil are not general at present, and at some factory's middle gears and the shared fuel tank of worm and gear, and the additive of sulfur-bearing such as rare hydrocarbon of sulfuration in the gear oil or chlorine has the deep-etching effect to copper, gear oil on the market is mainly based on sulphur or chlorine extreme-pressure additive at present, worm and worm wheel oil is then based on oiliness improver, so gear grease generally is not suitable for the lubricated of worm and gear.
The purpose of this invention is to provide and a kind ofly can satisfy the lubricated composite additive of lubricating oil of gear lubrication and worm and gear simultaneously.
Another object of the present invention provides the preparation method of a kind of gear and worm-type lubricant composite additive.
A kind of gear-worm gear composite additive of lubricating oil of the present invention is characterized in that basically being made up of extreme pressure anti-wear additives, oiliness improver, antirust and corrosion inhibitor, antioxidant, kilfoam and non-emulsifying agent, pour point depressant.
A kind of gear-worm gear composite additive of lubricating oil is characterized in that weight percentage is made up of extreme pressure anti-wear additives 10～60%, oiliness improver 10～60%, rust-preventive agent and corrosion inhibitor 1～5%, antioxidant 1～5%, kilfoam and non-emulsifying agent 1～5%, pour point depressant 0.5～20% basically.
Extreme pressure anti-wear additives of the present invention is wherein one or more of rare earth class additive, borate and borate ester additive, P-N type additive, sulfate-phosphate class additive.
Oiliness improver of the present invention is fatty acid, aliphatic alcohol ester and amine salt class, organic copper class etc., as in stearic acid, oleic acid, butyl oleate, oleic acid three hydramine, phosphoric acid ester, oleic acid epoxy ester, dimeracid glycol ester, oleic acid glycol ester, the rare hydrocarbon Oleum Gossypii semen of sulfuration one or more.
Rust-preventive agent of the present invention and corrosion inhibitor are 124 Triazole aliphatic amide salt, Sulfonates or metal carboxylate imidazolines etc.As one or more of N-oleoyl musculamine salt stearylamine, zinc naphthenate, Si Ben-80, oleic acid three alkanolamine ester, benzo three nitrogen wool grease magnesium soaps, 2-amine 2 bases 17 alkenyl imidazolines-dodecenylsuccinic acid salt, alkenyl succinic acid.
Kilfoam of the present invention and non-emulsifying agent are polyethylene oxide-propylene oxide.
Antioxidant of the present invention is benzotriazole analog derivative, thiadiazoles spread out class biology or dialkyl dithiophosphate.
Pour point depressant of the present invention is wherein one or more of polyacrylic ester, polyalphaolefin, vinyl acetate between to for plastic-divinyl two acid esters, ethylene propylene copolymer, acrylate-maleic acid, maleic anhydride copolymer.
Gear-worm gear is made of weight percentage basically with the preparation method of composite additive of lubricating oil extreme pressure anti-wear additives 10～60%, oiliness improver 10～60%, rust-preventive agent and corrosion inhibitor 1～5%, antioxidant 1～5%, kilfoam and non-emulsifying agent 1～5%, pour point depressant 0.5～20%, add in the mediation still of belt stirrer, slowly be heated to 80-120 ℃, be incubated 0.5-3 hour, the cooling back is continued at room temperature to be stirred to all materials and is dissolved transparent fully.
The present invention compared with prior art has following substantive distinguishing features:
(1) improves the supporting capacity of gear oil, improved gear life, improved the abrasion resistance of worm gear;
(2) adopt low-sulfur or do not have the sulphur technology, in the wear resistance that improves copper simultaneously, do not reduce the extreme pressure property of gear oil;
(3) has good demulsification performance.
In order to estimate the performance of gear and worm gear all-purpose engine oil composite additive, carried out following test:
(1) lubricating oil to preparation has carried out oil film strength and long term wear test on four ball experimental machine, estimates the friction and wear behavior of lubricating oil.(2) on the Timken friction wear testing machine copper alloy is carried out frictional coefficient and wearing and tearing mensuration: (load 365N, rotating speed 800r/min, room temperature), on the performance of lubricating oil, wearing and tearing and frictional coefficient should be the smaller the better.(3) on the Timken friction wear testing machine, tested the OK value.(4) on the FZG trier, supporting capacity is tested.(5) project of routine has been carried out corresponding test.
Used temperature is degree centigrade among the present invention, and used percentage ratio (%) is weight percentage.
In carrying out assessment of performance in 3% the ratio adding base oil, the result is as follows with above complex additive of the present invention:
The main physical and chemical index of table 1 composite additive
In carrying out performance test in 3% the ratio adding base oil, the result is as follows with composite additive:
