Description

A kind of compressor oil composition containing trihydroxymethylpropanyl ester
Technical field
The invention belongs to compressor oil technical field, combine particularly to a kind of compressor oil containing trihydroxymethylpropanyl ester Thing.
Background technology
Compressor oil is a kind of special lube, it be mainly used in the piston of compressor and the friction position of cylinder and Inlet and outlet valve and the lubrication of the driving member such as base bearing, the connecting-rod bearing, simultaneously also act as cooling moving parts friction surface and Seal the effect of the swept volume of gas compression.Owing to compressor is constantly in high pressure, high temperature and the environment with the presence of condensed water In, in order to ensure compressor safe handling, prolongation oil draining period, holding baric systerm is clean, reduce friction and transmission energy consumption, compresses Machine oil should have good high-temperature stability, prevents carbon deposit from generating, and also to have good anticorrosive, emulsion resistance and anti-foaming property.Remove Outside above-mentioned characteristic, compressor oil also should nontoxic, tasteless, disposable, environmentally safe.
Summary of the invention
It is an object of the invention to: for the deficiencies in the prior art, and provide a kind of compression containing trihydroxymethylpropanyl ester Engine oil base oil, to solve the problems such as fast, the poor high temperature stability of compressor oil rate of deterioration, extending machine oil uses the cycle, reduces Component wear.
To achieve these goals, the present invention is by the following technical solutions:
A kind of compressor oil composition containing trihydroxymethylpropanyl ester, including the composition of following percentage by weight:
Wherein, described base oil is the III class hydrogenated base oil by API classification；Group III base oil is to use full hydrogenation technique Prepare, compared with II class base oil, belong to the hydrogenated base oil of high viscosity index, also referred to as non-conventional base oil (UCBO).Group III Base oil considerably beyond I class base oil and II class base oil, especially has the highest Viscosity Index and the lowest in performance Volatility.The present invention mainly selects Group III base oil 100N and Group III base oil 150N.
Described artificial oil is PAO class artificial oil；The present invention mainly selects low viscous PAO 6#, this kind of artificial oil and mineral Oil phase ratio, without S, P and metal, and the not content of wax, so pour point is extremely low, generally below-40 DEG C, Viscosity Index is generally more than 140。
Trihydroxymethylpropanyl ester is a kind of polyol ester, has oxidation stability and thermal stability, good lubricity With extreme pressure property, extremely suitable for preparing high perofmrnace lubricating oils.In addition, it is necessary to explanation, base oil and PAO class artificial oil The polarity of itself is little, dissolves the ability of polar additive, can be overcome by adding a certain amount of trihydroxymethylpropanyl ester.
Described compressor oil compound additive is LZ 5404 compound additive.This compressor oil compound additive quality is steady Fixed, there is good wear resistence, antioxidant, antirust, corrosion protection and thermal oxidation stability, the oil draining period is obviously prolonged.
The described compressor oil composition containing trihydroxymethylpropanyl ester, also includes 0.2-2%'s by weight percentage Metal deactivator, described metal deactivator is at least one in thiadiazole derivant and benzotriazole analog derivative.Metal watch In the face of oil ageing can play catalytic action, acted on metal surface by metal deactivator, shield its catalytic action.With This simultaneously, metal deactivator also can play anti-oxidation efficacy, and it plays synergism with antioxidant.
The described compressor oil composition containing trihydroxymethylpropanyl ester, also includes by weight percentage 0.1～1% Extreme pressure anti-wear additives, described extreme pressure anti-wear additives is at least one in olefine sulfide and phosphate ester.Extreme pressure anti-wear additives typically has height Active group, under the High Temperature High Pressure of local, can react formation protecting film with metal surface.Therefore, extreme pressure anti-wear additives is at metal Under conditions of load is born on surface, can prevent the abrasion of metal surface, scratch from even sintering.
Described viscosity index improver be three block coupling hydrogenated styrene-butadiene copolymers, polyisobutylene, ethylene- At least one of alpha olefin copolymer.Viscosity index improver mainly improves the viscosity-temperature characteristics energy of lubricating oil, improves its viscosity and refers to Number.It has the good compatibility with other components of the present invention, and ratio selects properly can not only improve the viscosity-temperature characteristics energy of oil product, Compositions can also be made to have the anti-shear performance of excellence, it is ensured that oil product still has under engine high-temperature, high shear environment simultaneously There is suitable viscosity.
Described antioxidant be double octyl group zinc dithiophosphate, zinc dialkyl dithiophosphate, DBPC 2,6 ditertiary butyl p cresol, At least one in alkylated diphenylamine and N-phenyl-a-naphthylamine.Antioxidant is by absorbing free radical and peroxynitrite decomposition compound Form, blocker mixed oxidization decay process, thus play the effect improving Working Life of Lubricating Oil.Wherein, double octyl group two sulfur Being 9.0～10.5% for the percentage composition of Zn in zinc phosphate, it is steady that it has excellent oxidation corrosion resistance, abrasion resistance and heat Qualitative energy.
Described anti-foaming agent is at least one in poly-methyl-silicone oil and fluoro-alkyl ether.Anti-foaming agent is typically with fine particle shape Formula is dispersed in lubricating oil, the stability with bubble surface effect reduces bubble, reaches anti-bubble or froth breaking effect.Adding of anti-foaming agent Dosage is the lowest, maximum less than 1%.
Described pour-point depressant is at least one in poly alpha olefin, polymethacrylates and alkylnaphthalene.The effect of pour-point depressant Mechanism is to form cocrystallization with paraffin, changes size and the profile of paraffin crystal, is allowed to not be easily formed network structure, plays reduction The effect of freezing point.
Preferably, the described compressor oil composition containing trihydroxymethylpropanyl ester, including the group of following percentage by weight Become:
Being more highly preferred to, the described compressor oil composition containing trihydroxymethylpropanyl ester, including following percentage by weight Composition:
The described compressor oil composition containing trihydroxymethylpropanyl ester, its preparation method comprises the following steps:
