Abstract
The invention discloses an additive for wear resistance of lubricating oil, which comprises the following components in part by weight: 15 to 35 parts of antiwear agent, 6 to 29 parts of detergent dispersant and 12 to 26 parts of antioxidant preservative, wherein the antiwear agent consists of boric acid tributylester, phosphonic acid dibutyl ester, copper isooctoxyborate and cupric cyclohexoxylborate; the detergent dispersant consists of polybutene amine, polyisobutene carbamic acid ester and 2-aminopyridine; and the antioxidant preservative is boronized butanimide. The additive has wide use range, can be used in paraffin, naphthene and intermediate base oil, and also can be used in synthetic and semi-synthetic base oil. The additive has the advantages of effectively improving the wear resistance of the lubricating oil, strengthening the bearing capacity of the lubricating oil, making the lubricating oil have long service life, and having small dosage in the lubricating oil and simple and convenient preparation process.
Description
Technical field
The present invention relates to a kind of additive for wear resistance of lubricating oil, relate in particular to a kind of additive for wear resistance of lubricating oil of forming by anti-wear agent, detergent-dispersant additive, antioxidant preservative.
Background technology
The running of equipment be unable to do without lubricating oil, and lubricating oil be unable to do without oil dope, and oil dope is the marrow of modern various senior lubricants.According to statistics, about 30% energy consumption is in friction, and 80% part of damage is scrapped by wearing and tearing.Therefore, improve lubricity to reduce friction, to wear and tear and to prevent that sintering is significant to national economy.The most frequently used additive is an extreme-pressure anti-friction additive in the lubricating oil, under condition of boundary lubrication, is used to improve the base oil tribological property, and the friction resistance between the pair of reducing friction reduces wearing and tearing and scratch, finally reaches the purpose of the carrying that improves lubricating oil.
Extreme-pressure anti-friction additive such as sulphur phosphorus type (SP) the gear oil extreme pressure anti-wear agent using and study at present; I. C. engine oil, antiwear hydraulic oil are with the anti-rotten wear-resistant multipurpose of zinc dialkyl dithiophosphate (ZDDP) antioxygen; Organic-molybdenum, tungsten low friction compound; Organic copper and nano-copper sulfide low friction compound, nanometer cerium, lanthanum rare earth anti-wear agent, ceramic anti-wear agents such as Nano diamond, SP 1, silicon-dioxide; Oildag, molybdenumdisulphide, tetrafluoroethylene antifriction and antiwear agents; Salt and ester extreme pressure anti-wear additives thereof such as dithiocarbamic acid zinc, copper, molybdenum, cadmium, antimony, but these additives or the independent supporting capacity of using are low, like sulphur, phosphorus and chlorine extreme pressure anti-wear additives scuffing of cylinder bore seizeization watt accident take place easily under the sh extreme condition; Perhaps consume excessively easily and cause lubricating oil shorter work-ing life for forming used extreme pressure anti-wear additives of effective tempered oil film layer such as the agent of sulphur phosphorus; Perhaps fabrication process condition is strict with nano ceramics, Nano diamond and imidazoles fluorine boron ionic liquid etc., also is difficult to produce in enormous quantities the supply of material at present.
Summary of the invention
The present invention is the problems referred to above during the present traditional anti-wear agent of solution is promoted the use of, and provides a kind of wear-resistant bearing capacity strong, long service life, the additive for wear resistance of lubricating oil that additive capacity is little and production technique is easy.
The weight of additive for wear resistance of lubricating oil of the present invention consists of:
15～35 parts of anti-wear agents;
6～29 parts of detergent-dispersant additives;
12～26 parts of antioxidant preservatives;
Wherein, said anti-wear agent is made up of tri-n-butyl borate, di-n-butyl phosphite, different octyloxy copper borate and cyclohexyloxy copper borate; Said detergent-dispersant additive is made up of polybutylenes amine, polyisobutene carbamate and diamino-pyridine; Said antioxidant preservative is the boronation succimide.
The weight of preferred said anti-wear agent consists of:
5～10 parts of tri-n-butyl borates;
3～9 parts of di-n-butyl phosphites;
2～8 parts of different octyloxy copper borates;
5～8 parts of cyclohexyloxy copper borates;
Said detergent-dispersant additive weight consists of:
2～12 parts of polybutylenes amine;
3～8 parts of polyisobutene carbamates;
1～9 part of diamino-pyridine.
The used tri-n-butyl borate of the present invention, di-n-butyl phosphite, different octyloxy copper borate and cyclohexyloxy copper borate not only have fabulous extreme-pressure anti-wear antifriction quality; And has a good thermal oxidation stability; Under the high temperature to the copper non-corrosiveness; Iron and steel is had good anti-rust properties, also have good seal compatibility simultaneously, help improving operating environment; Colloid, greasy filth, carbon deposit and abrasive particle that the used detergent-dispersant additive of the present invention is used for solubilising, disperses the lubricating oil use to produce; Prevent that gum deposit influences the equipment normal operation in lubricating oil; Adopt amine polybutylenes amine, ammonia ester type polyisobutene carbamate and heterogeneous ring compound diamino-pyridine synergy; Can effectively remove oxidation generation acidulous material in the oiling system, make lubricating oil also have the antiacid corrosive power of certain antioxygen, thereby strengthened its lubricating function.
The preparation of additive for wear resistance of lubricating oil of the present invention adopts conventional blending means at normal temperatures and pressures promptly, and each component is added Mixer pot, promptly gets after stirring.Additive of the present invention joins in the lubricating oil according to the ratio of 0.1～2.0wt% in use, mixes to get final product.
Additive use range of the present invention is wide, both can in paraffin, cycloalkanes, intermediate base base oil, use, and can in synthetic, semi-synthetic base oil, use again.Add additive of the present invention and can effectively improve the wear resistance of lubricating oil, the supporting capacity of lubricating oil is strengthened, long service life, and additive capacity is little in lubricating oil, and manufacture craft is easy.
