Abstract

The present invention is the ashless organic wear preventive additive of a kind of phosphorus-nitrogen type of not sulfur-bearing, and it is an aryl phosphate ester class thing, long-chain organic amine thing, the organic reaction mixture of mulit-hydroxy fatty acid ester or polyprotonic acid fat carboxylic ester class thing and benzotriazole.Strong in order to synthetic wearproof lubricant resistance to emulsion, facile hydrolysis does not corrode copper and silver, and abrasion resistance is good, is particularly useful for semi-fluid or boundary lubrication operating mode, for example the injection pump antiwear hydraulic oil; Also be applicable to lubricating of oil bearing etc.; Also can add extreme-pressure additive modulation extreme pressure industrial gear oil.

Description

The present invention relates to a kind of ash-free, Wear-resistant phosphorus-nitrogen (P-N) type additibve and manufacture method thereof of lubricating oil product.The special lubricating oil product that add this wear preventive additive especially are suitable for the semi-fluid or the boundary lubrication operating mode of mechanical parts, are suitable for contacting easily the oil lubrication system of water.
Widespread use lubricating oil product in mechanical transmission and the controlling organization often adds some wear preventive additives to reduce wearing and tearing in lubricating oil product, promptly make antiwear hydraulic oil as suitably adding an amount of wear preventive additive in the hydraulic efficiency oil of using at injection pump.U.S. Pat 4537696(1985) and PCT patent WO8404319 all propose to make wear preventive additive with dialkyl group carbophenothion acid zinc (ZPTP).Dialkyl group carbophenothion acid zinc is the sulphur phosphoric acid organic salt of metallic zinc, is a kind of surface active cpd.Meet water capacity facile hydrolysis, can generate alkyl sulfide phosphoric acid and sulphur in the hydrolytic process.Sulphur phosphoric acid is a kind of emulsifying agent, and it can make lubricating oil be difficult to separate with water generation emulsification, so that the deterioration of lubricant inefficacy, and for example the lubricating oil in the fuel tank in winter lost efficacy because of contacting the emulsified back of issuable water of condensation, must the replacing new oil.Sulphur is corrosive to copper and silver, and that mechanical parts such as bearing etc. are selected for use is copper more, often influences work-ing life owing to generating the corrosion of sulphur to them after the hydrolysis.
It is strong to the purpose of this invention is to provide a kind of resistance to emulsion, and resistance to hydrolysis is good, the ashless organic wear preventive additive of resistance to abrasion phosphorus-nitrogen type better, not sulfur-bearing.This new additive agent is facile hydrolysis not, is difficult for making oil and water generation emulsification, does not contain sulphur, thereby can not produce corrosion to copper, silver-colored part, belongs to Ashless type, and abrasion resistance is good.
Wear preventive additive provided by the invention is that aryl phosphate ester, long-chain organic amine, polyhydroxy-alcohol fatty acid ester or alicyclic polybasic acid fatty alcohol are with the organic reaction mixture of Ben And triazole.Its composition by weight per-cent is aryl phosphate ester 40% to 90%, long-chain organic amine 2% to 15%, and both can appoint one or Er person And usefulness polyhydroxy-alcohol fatty acid ester or alicyclic polybasic acid fatty alcohol, amount to 10% to 50% , Ben And triazole 0.5% to 5%.In application, aryl phosphate ester can adopt Tritolyl Phosphate; The long-chain organic amine can adopt stearylamine; The polyhydroxy-alcohol fatty acid ester can adopt Sorbitol Powder fatty acid ester or pentaerythritol fatty ester, and the alicyclic polybasic acid fatty alcohol can adopt dioctyl sebacate.
Method of manufacturing technology is: aryl phosphate ester class thing, long-chain organic amine thing He Ben And triazole are added in the reactor by above-mentioned weight percent mix earlier, be heated to 70 ℃ to 150 ℃, maintain then under this temperature and stirred 6 hours to 20 hours, add alicyclic polybasic acid fatty alcohol or polyhydroxy-alcohol fatty acid ester by above-mentioned weight percent again, continue 1 to 4 hour postcooling blowing of insulated and stirred again.The mixed solution of emitting is the concentrated solution of the ashless organic wear preventive additive of phosphorus-nitrogen type of indication of the present invention, and concentrated solution at room temperature is a kind of lurid oily matter, and zero pour is lower than 0 ℃, and flash-point is greater than 200 ℃.Concentrated solution can dilute with thinner, and thinner can adopt hyperoxic poly-hydroxy or polybasic ester class thing, for example binary carboxylic esters, pentaerythritol fatty ester, Sorbitol Powder fatty acid ester, trihydroxymethylpropanyl ester.
This novel wear preventive additive can any ratio and lubricating oil product mix, can not influence the zero pour of lubricating oil product after the mixing.This wear preventive additive that adds 0.1-1% in lubricating oil product just can present wear-resistant effect, and general addition is 0.1% to 10% by weight.This wear preventive additive also can be to other additives of lubricating oil product, as oxidation inhibitor, tackifier, pour point depressant, defoamer etc. are compatible, the back forms the compound wear resistant extreme-pressure additive, and then modulation extreme pressure industrial gear oil and hyperboloidal gear wet goods also can to dope extreme-pressure additive (as two sulphur dibenzyls, many sulfide isobutenes, dialkyl group carbophenothion acid zinc).
Good with the antiwear hydraulic oil abrasion resistance that ash-free, Wear-resistant phosphorus-nitrogen (P-N) type additibve provided by the invention is modulated into, resistance to abrasion is higher than with the synthetic antiwear hydraulic oil of dialkyl group carbophenothion acid zinc wear preventive additive greater than 90 ℃ the time, record copper weightlessness through the ASTM.D-2619 hydrolysis experiment and be bordering on vestige, separation time was less than 30 minutes when the test of ASTM.D-1401 demulsibility records at 54C, index advanced person, excellent property.Can be modulated into multiple wearproof lubricants such as the low moment of torsion lubricating oil of ashless anti-wear hydraulic oil, sound-track engraving apparatus oil bearing abrasion-proof lubricant oil, sewing machine, compound extreme pressure industrial gear oil with this wear preventive additive, application benefit is remarkable.As ashless anti-wear hydraulic oil, be applied to ram pump and high pressure vane pump and record pump after one to two year and do not have noticeable wear, copper spare there is not corrosion substantially.
The ash-free, Wear-resistant phosphorus-nitrogen (P-N) type additibve prescription is as follows with manufacturing embodiment:
Prescription (weight percent):
Tritolyl Phosphate: 80%
Stearylamine: 10%
Ben And triazole: 0.8%
Sorbitol Powder fatty acid ester: 1.4%
Diisooctyl sebacate: 1.8%
Manufacturing process:
Tritolyl Phosphate, stearylamine, Ben And triazole are put into reactor mixing post-heating to 110 ℃, keep this Wen Du And to be stirred 14 hours, add Sorbitol Powder fatty acid ester and diisooctyl sebacate again, continue then to stir 3 hours, after cooling blowing.Optionally add an amount of thinner.
