Technical field
The invention belongs to lubricating composition technical field, relate to a kind of lubricant oil composite, particularly a kind of ashless hydraulic fluid compositions.
Background technology
Hydraulic oil as hydraulic system power transmitting medium is a kind of plural equilibrium system containing multiple additives, and widely used zinc dialkyl dithiophosphate (ZDDP) is as multi-functional antiwear additive.But, easily environment is caused containing zinc hydraulic oil heavy metal pollution, and when being in use subject to water pollution, zinc dialkyl dithiophosphate ZDDP is easily hydrolyzed generation greasy filth blocking filter, and copper has certain corrosivity.
Ashless hydraulic fluid can well make up the deficiency containing zinc hydraulic oil, avoid heavy metal problem of environmental pollution, reduce ash and greasy filth in fluid to produce to pollute, improve detergency and filterability, meet European Union's ecology regulation and worker health security legislation and the environmental regulation requirement of some region such as forest.Therefore, ashless hydraulic fluid is the direction of development, and its demand constantly increases, both at home and abroad to ashless hydraulic fluid technical research also at development.
US Patent No. 5254272 describes a kind of ashless lubricating oil compositions, containing base oil, adopts sulfuration synthetic ester and thiodiphenvl phosphate amine salt as antiwear additive.Said composition is applied in hydraulic oil, and the hydrolysis stability of thiodiphenvl phosphate ester ammonium salt is poor, when there being water to pollute, it is easy to produce greasy filth, and copper has certain corrosivity.
US Patent No. 5531911 describes a kind of functional liquid, containing base oil, adopts triphenylphosphorothionate and dibutyl dithio phosphate ester as antiwear additive, and aryl sulfonic acid ammonium salt is as antirust agent.This functional liquid is applied in hydraulic oil, and aryl sulfonic acid ammonium salt resistance to water is poor, has under water condition and easily produces corrosive degradation byproducts, corroding metal parts and generation greasy filth blocking filter.
US Patent No. 2002/0010103A1 describes a kind of lubricant oil composite with outstanding heat stability and extreme pressure and antiwear behavior, containing base oil, adopting tricresyl phosphate to arrange in pairs or groups as antiwear additive with phosphite ester, dodecenylsuccinic acid derivant, laurylene base succinamide derivant or anil are as antirust agent.Said composition is applied in hydraulic oil, and the activation temperature of phosphate ester front three phenolic ester is higher, and anti-wear effect under low pressure and low load is also inconspicuous, and phosphite ester is easily hydrolyzed, and hydrolysis stability is poor.
US Patent No. 6531429 describes a kind of lubricant oil composite, containing base oil, adopting triphenylphosphorothionate and diisopropyl disulfide substituted phosphate as antiwear additive, phosphate amine salt is as antirust agent, and with the addition of polyol ester, amine or epoxide and improve filterability.Said composition is applied in hydraulic oil, phosphate amine salt is easily hydrolyzed, and wet filter is poor, although this patent is by adding polyol ester, amine, epoxide, improve wet filter, but still existence and divalent metal easily react formation greasy filth blocking filter.
US Patent No. 2004/0259743A1 describes a kind of lubricant oil composite with abrasion resistance, containing base oil, have employed alkyl phosphoric acid ester ammonium salt and the diisooctyl phosphordithiic acid addition compound product with acrylamide as antiwear additive, and with the addition of hindered phenol and amine type antioxidant and matal deactivator.This compositions can be applied in hydraulic oil, and alkyl phosphoric acid ester ammonium salt is easily hydrolyzed equally, and wet filter is poor.
US Patent No. 2005/0096236A1 describes a kind of ashless additive formula being suitably applied in hydraulic oil; containing base oil; have employed tributyl phenyl phosphorothioate and acid dialkyl dithiophosphate as antiwear additive, N-acyl group sarcosine is as antirust agent.This ashless additive formula is applied in hydraulic oil, is not suitable for II, Group III base oil, and the rustless property in II, Group III base oil is poor, it is impossible to by ASTMD665B corrosion test requirement.
Chinese patent CN102399612A, disclose a kind of without zinc High Pressure Antiwear Hydraulic, and specifically disclose techniques below feature " including the component of following mass percent: base oil 98.5%～99%, antioxidant 0.2%～0.4%, extreme pressure anti-wear additives 0.7%～0.9%, antirust agent 0.04%～0.07%, matal deactivator 0.04%～0.08%, detergent-dispersant additive 0.015%～0.05%, anti-foaming agent 0.0002%～0.0005% ".
The base oil selected in this patent is I class HVI150 and HVI500, and viscosity index (VI) is less than 110.
I class base oil contains the impurity such as a certain amount of unsaturated hydrocarbons, sulfur, nitrogen, therefore that the dissolubility of additive single dose is relatively strong, and the susceptibility of antiwear additive is better, but shortcoming to be oxidation stability poor, service life is shorter.
II/III class base oil is refined deep, completely based on saturated hydrocarbons material, the hetero atom such as sulfur-bearing, nitrogen hardly, advantage is that oxidation stability is good, it is significantly better than I class base oil service life, shortcoming is that II/III class base oil is poor to dissolubility and the susceptibility of the additives such as antiwear additive, matal deactivator, antirust agent, and therefore selection and the law of compound of additive are proposed higher requirement by II/III class base oil.
It addition, the antirust agent in this patent is sulfonate or carboxylic acid and carboxylate (based on calcium salt), therefore hydraulic oil combination property under meeting water condition is bad.
It is experimentally confirmed antirust agent having the greatest impact to wet filter (ISO13357) performance, but ashless anti-rusting additive susceptibility in II/III base oil is poor simultaneously, single ashless anti-rusting additive cannot meet the test of ASTM665B anti-corrosion and the test of ISO13357 wet filter simultaneously, it is necessary to carries out multiple ashless anti-rusting additive composition research and could pass through above-mentioned two tests simultaneously.
Along with hydraulic technique to high speed, high pressure, high load capacity development, hydraulic system is small compact more, volume of fuel tank and gap are less, filtering accuracy is higher, this just requires that hydraulic oil has better wear resistence, hydrolysis stability, heat stability, oxidation stability, filterability and anti-corrosive properties and longer service life.The standard of hydraulic oil and specification are also in constantly revision and upgrading, as hydrolysis stability, oxide etch and filterability are had higher requirement by DenisonHF-0 (2012) specification, it is additionally arranged heat stability, filterability test, and the blade of high-voltage pulse loading and plunger mixing double pump (T6H20C) are done, wetting phase bench test.DenisonHF-0 (2012) specification is the standard of the representative antiwear hydraulic oil peak performance level generally acknowledged in the world at present, and common hydraulic oil is difficult to the detection by this standard.
Summary of the invention
The technical scheme is that the oxidation stability in order to overcome prior art to exist is poor, service life is shorter, to the dissolubility of the additives such as antiwear additive, matal deactivator, antirust agent and susceptibility is poor, hydraulic oil combination property under meeting water condition is bad weak point, and a kind of ashless hydraulic fluid compositions with the hydrolysis stability of excellence, filterability, wear resistence and oxidation stability and low greasy filth is provided, it can meet GB11118.1-2011 and DenisonHF-0 (2012) specification standards.Antirust agent is the composite mixture of sarcosine derivative and amino acid derivativges or organic amide, therefore uses the hydraulic oil of ashless hydraulic fluid compositions blending to have better combination property under meeting water condition.
