Description
Technical field
The present invention relates to lubricating oil field, the industrial gear oil that is specifically related to a kind of antioxidant composition, its purposes and comprises it.
Background technology
The thermal oxidation process of organic compound comprises a series of free chain reaction, under the effect of heat, light or oxygen, the chemical bond of organic compound molecule ruptures, generate active free radical and hydroperoxide, hydroperoxide generation decomposition reaction, generates hydrocarbon oxyradical and hydroxyl radical free radical.These free radicals can cause a series of free chain reaction, cause structure and the character generation fundamental change of organic compound.The effect of oxidation inhibitor is to eliminate the free radical just having produced, or impels the decomposition of hydroperoxide, stops the carrying out of chain reaction.The oxidation inhibitor that can eliminate free radical has compound and the derivatives thereof such as aromatic amine, hindered phenol, is called primary antioxidant; The oxidation inhibitor of energy hydroperoxide decomposition has the organic compound of phosphorous and sulfur-bearing etc., is called auxiliary antioxidant.
The oxidation stability of extreme pressure type industrial gear oil is present stage one of more scabrous problem always.Due to adding of extruding anti-wear agent, under high temperature oxidation, oil product is as easy as rolling off a log rotten.Especially, it is base oil component that Industrial Closed gear oil is used the paraffinic base neutral oil of suitable proportion and bright stock more, bright stock is the heavier oil product obtaining from oil residual component, the component with longer molecular chain, under high temperature oxidation, also very easily impel chainpropagation, the viscosity of oil product is increased.
The test of extreme pressure type industrial gear oil oxidation stability adopts SH/T0123 standard method (the method is drafted by Lanzhou oil-refining chemical head factory, adopts by reference ASTM D2893-88 < < extreme pressure lublicating oil oxidation susceptibility assay method > >) conventionally.During test, in special Glass tubing, add 300mL formation testing, at 121 ℃, with certain speed, in pipe, pass into air 312h, with the formation testing viscosity rate of increase recording, represent the thermal oxidation stability of formation testing.Test viscosity rate of increase is little, illustrates that the work-ing life of oil product is longer, and oxidation stability is good.Product index requires as " 100 ℃ of viscositys increase be not more than 6%, sludge number is not more than 0.1ml ".
At present, conventional Industrial Closed gear oil L-CKD320 in Chinese market, 680 etc., according to the method test of SH/T0123, test-results there will be viscosity to increase the situation that surpasses 6%, the oxidation stability that existing oil product is described is still not ideal enough, and a kind of novel additive of continual exploitation is to improve the oxidation stability of industrial gear oil.
Summary of the invention
For overcoming the deficiency of existing industrial gear oil's oxidation stability aspect, find a kind of oxidation inhibitor that is more applicable for industrial gear oil, the object of this invention is to provide a kind of antioxidant composition.
Another object of the present invention is to provide a kind of purposes of antioxidant composition.
Another object of the present invention is to provide a kind of industrial gear oil.
Antioxidant composition provided by the invention, comprises by mass percentage:

In above technical scheme, described phenolic ester type oxidation inhibitor is selected from β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid isooctyl alcohol ester.Structural formula is as follows:
The preparation process of antioxidant composition provided by the invention is: alkylated diphenylamine oxidation inhibitor and phenolic ester type oxidation inhibitor are proportionally mixed, at the temperature of 45 ℃-50 ℃, use machinery or hand mixing evenly, wherein, order of addition(of ingredients) is not particularly limited.
Antioxidant composition provided by the invention can obviously improve oxidation of lubricating oil stability, and therefore, the present invention also provides antioxidant composition described in the above technical scheme any one purposes as industrial gear oil additive.
Preferably, described industrial gear oil is Industrial Closed gear oil; More preferably, described industrial gear oil is extreme pressure type heavy loading (L-CKD) Industrial Closed gear oil.
The present invention also provides a kind of industrial gear oil, comprises by mass percentage the antioxidant composition described in 0.1～1.0% above technical scheme any one.
Preferably, described industrial gear oil comprises the antioxidant composition described in 0.1～0.5% above technical scheme any one by mass percentage.
Preferably, described industrial gear oil is Industrial Closed gear oil; More preferably, described industrial gear oil is extreme pressure type heavy loading (L-CKD) Industrial Closed gear oil.
It is base oil component that existing Industrial Closed gear oil is used paraffinic base neutral oil and bright stock more; in 680 viscosity ranks; conventionally also can add polyisobutene viscosity index improver to reach the viscosity of oil product requirement, to refer to that agent adds fashionable when glutinous, and the antioxidant property of oil product is had higher requirement.Conventional industrial gear oil's oxidation inhibitor has shield phenol type and amine type compound antioxidant, belong to chain cessationer, can generate stable product (ROOH or ROOA) with peroxidation base (ROO), thereby prevent the oxidizing reaction of hydrocarbon compound in lubricating oil, as 2,6-ditertbutylparacresol, 4,4-methylene radical bis-phenol, a-naphthylamines, N, N-di-sec-butyl-p-phenyl enediamine etc.
Compare existing oxidation inhibitor, antioxidant composition provided by the invention has adopted two kinds of dissimilar oxidation inhibitor to carry out composite, two-way interaction has produced good synergistic effect, especially, can suppress viscosity growth and the sedimental generation of bright stock base oil, polyisobutene viscosity index improver.Antioxidant composition provided by the invention can obviously improve oxidation of lubricating oil stability, is particularly useful in Industrial Closed gear oil.In addition, antioxidant composition cost provided by the invention is lower, and preparation process is easy.The industrial gear oil that comprises described antioxidant composition provided by the invention has improved the oxidation stability of oil product greatly, the growth of oil product viscosity can be controlled under 6%, and effectively suppress sedimental generation.
