Abstract
The invention relates to automobile gear lubricating oil containing borate. The gear lubricating oil is prepared through taking neopentyl polyol ester as base oil, adding a small amount of sulfur, nitrogen and boron-containing boride borate BNS, dialkyl pentasulfide (RC2540) and phosphide P120, and mixing uniformly. The formula is as follows: neopentyl polyol ester serves as the base oil, and the following ingredients, which account for the weight percent of neopentyl polyol ester, are added: 0.05-0.65% of BNS, 0.05-0.65% of RC2540 and 0.1-0.7% of P120. The gear lubricating oil has excellent extreme-pressure wear resistance, high bearing capacity which can reach 1,906N and the lowest wear scar value of 0.255mm, can be used for preparing vehicle gear oil and can also be applied to medium-duty industrial gear oil.
Description
Technical field
The present invention relates to a kind of lubricating oil, particularly relating to a kind of take neopentyl polyol ester as the gear grease that base oil adds boric acid ester.
Background technology
Along with the enhancing of mankind's environmental consciousness, based on mineral oil oil lubricating oil will substitute by environmentally friendly base oil.Traditional lubricating oil great majority oil based on mineral oil, mineral oil also exists the problem that biodegradable difference etc. constitutes a threat to environment and health.Neopentyl polyol ester class oil can be used for grease base plinth oil, mainly under the working conditions of harshness, protects machine part, is particularly useful for low temperature and high temperature grease.Do the lubricating grease generally very difficult service requirements meeting more than less than-60 DEG C and 150 DEG C of base oil with mineral oil, and the use temperature scope of lubricating grease oily based on polyol-ester type oil is generally at-37 ~ 200 DEG C.The lubricity of neopentyl polyol ester is better than dibasic acid esters, mineral oil, is far superior to poly-alpha olefins (PAO), although and the ester viscosity of long and short chain mixing is little, there is minimum frictional coefficient; Neopentyl polyol ester has good sticky warm nature and volatility..
Boron has the title of nonactive lubrication element.Boric acid ester, except having excellent extreme-pressure anti-wear friction reduction characteristics, has anti-oxidant and erosion resistance, excellent rust-preventing characteristic, preservative property toward contact simultaneously, and nontoxic odorless, to characteristics such as metal substrate non-selectivities, because of but the multi-functional lubricating oil additive of a class.
Novel boron-containing additive obviously can improve the oxidation-resistance of lubricating oil, rust-preventing characteristic, thermal stability and antiwear and friction reduction property etc.The progress of boron additive, comprises boracic purification agent, boron-containing dispersant, boracic extreme pressure anti-wear additives and boracic rust-preventive agent, thinks that multi-functional boron-containing additive is following developing direction.Organic boric acid ester is a kind of multifunctional additive for lubricating oil, has excellent antiwear and friction reduction property.The boric acid ester that organic boric acid ester particularly introduces long chain hydrocarbon groups has fabulous oil soluble, directly can be dissolved in base oil and use.Carbon, hydrogen 2 kinds of elements are generally only had in the alkyl of the simple boric acid ester of early stage synthesis.Along with deepening continuously of research, in boric acid ester structure, introduce the elements such as oxygen, nitrogen, sulphur, phosphorus, chlorine gradually, make boric acid ester have many-sided function.
Organic boric acid ester has huge potentiality in the application of boundary lubrication.Boric acid ester compound abundant raw material source, lower to equipment requirements, synthetic method is simple, and cost is lower.And boric acid ester has the concern that many excellent properties cause people just day by day, the application of boric acid ester has very wide prospect.Wherein the boric acid ester over-all properties of amide containing and tetrahydroglyoxaline is comparatively outstanding.The abundant raw material of synthesis boric acid ester, simple to operate, be easily applied to production practice.
Summary of the invention
Adopt the boride containing nitrogen and sulphur, Uniform Design and artificial neural network optimization method is adopted to carry out being optimized test-results with the star of dialkyl pentasulfide RC2540 and the compound phosphorus containing phosphorus, find out the combination of the additive of supporting capacity performance, and verify, the good composite test of three kinds of additives filtered out.
Object of the present invention, be to provide a kind of Automobile gear lubricant containing boric acid ester, this lubricating oil extreme pressure and antiwear behavior is high, and supporting capacity is strong.
The technical scheme adopted is a kind of Automobile gear lubricant containing boric acid ester, and it is characterized in that this lubricating oil is is base oil by neopentyl polyol ester, adds boride BNS, dialkyl pentasulfide RC2540 and P120, mixes make through heating.
The weight percent of the star P120 of the boride BNS that neopentyl polyol ester adds, dialkyl pentasulfide RC2540 and phosphorus is:
BNS is 0.05%-0.65%;
RC2540 is 0.05%-0.65%;
P120 is 0.1-0.7%.
The present invention has fabulous extreme pressure and antiwear behavior, and supporting capacity is high, and configurable comparatively heavy duty automobile gear oil, also can be used for heavy loading and medium duty industrial gear oil.
The mechanism that extreme pressure anti-wear of the present invention is good, bearing capacity is high:
Boric acid ester has good anti-wear and wear-resistant performance, and after introducing the elements such as Cl, S, P in molecule, the boric acid ester of some structure also has anti-extreme pressure energy.The research of boric acid ester antifriction antiwear mechanism is proved, under condition of boundary lubrication, organic boronic ester molecule is through the process of the complexity such as absorption, cracking, polymerization, condensation, deposition and friction boronising, produce adsorption film, friction polymer film, surface deposition film and permeable membrane at friction surface, thus play friction-reducing and antiwear action.The friction condition that these surface film generate is not quite similar, and thus various surface film Individual existence sometimes, sometimes exists simultaneously and play antiwear and antifriction effect.Particularly nitrogenous boric acid ester, not only has good abrasion resistance, also has higher hydrolysis-stable acid esters, not only has good abrasion resistance, also has higher stability to hydrolysis, rust-preventing characteristic, oxidation-resistance.
Neopentyl polyol ester (Neopentyl Polyol Ester NPE-3) is that in molecular structure, ester group ortho position is a class synthetic ester of quaternary carbon atom, than dibasic acid esters, there is more excellent heat and stability to hydrolysis, mainly comprise DOPCP, trihydroxymethylpropanyl ester and pentaerythritol ester.Its physicochemical property is in table 1.
The boride of sulphur and nitrogen is boric acid ester BNS, and this compound is synthesized by Shanghai Communications University.10.85% sulphur wherein containing total molecular weight, 4.75% nitrogen and 1.85% boron, all the other are hydrocarbon thing.
Dialkyl pentasulfide, code name is RC2540.Product is light brown clear liquid, can the vulcanized oil that obtains base oil sulfuration of extraordinary substituted element sulphur.Its active sulphur content rises along with temperature and increases (can reach 38%) in addition, and result is that temperature slightly rises (50-60 DEG C), has significant extreme pressure effect.Also can compound use effective with other sulfur-containing additive for improving extreme pressure property further.As: with phosphorodithioic acid zinc salt, phosphoric acid partial ester or ashless sulphur-phosphorus additive compound use, abrasion resistance can be improved further.Phosphorus containing trace is extreme pressure agent anti-wear agent.
