Description
Technical field
The present invention relates to a kind of lubricating oil, particularly relate to a kind of automobile rust preventive lubricating oil.
Background technology
Lubricating oil is generally made up of base oil and additive two portions.Base oil is lubrication main body of oil, and decide the essential property of lubricating oil, additive then can make up and improve the deficiency of base oil aspect of performance, gives the performance that some is new, is the important component part of lubricating oil.
Lubricant base mainly divides mineral base oil, synthetic base oil and biological basis oil three major types.Mineral base oil, is widely used, consumption very large (about more than 95%), but some application scenario then must use the product of synthetic base oil and bio oil formulation of base oil, thus makes these two kinds of base oils be developed rapidly.
Mineral base oil is refined by crude oil and forms.The main production process of lubricant base has: atmospheric and vacuum distillation, solvent deasphalting, solvent treatment, solvent dewaxing, carclazyte or hydrofinishing.Nineteen ninety-five has revised the lube base oil standard of China's current, mainly have modified sorting technique, and adds the low solidifying and special base oil standard of deep refining two class.The production of mineral type lubricating oil, the most important thing is to select best crude oil.
The chemical composition of mineral base oil comprises high boiling point, high-molecular weight hydrocarbon and non-hydrocarbons mixture.Its composition is generally alkane (straight chain, side chain, higly branched chain), naphthenic hydrocarbon (monocycle, dicyclo, many rings), aromatic hydrocarbons (mononuclear aromatics, polycyclic aromatic hydrocarbons), cycloalkyl aromatic hydrocarbons and containing oxygen, nitrogenous, organic compounds containing sulfur and the non-hydrocarbons such as colloid, bituminous matter.Biological basis oil (vegetables oil) is just more and more welcome, and it can biological degradation and reduce environmental pollution rapidly.Because the measure reducing environmental pollution is all being sought by industrial enterprises all in the world today, and this " natural " lubricating oil just having this feature, although vegetables oil cost is high, the expense increased is enough to the environmental improvement expense offsetting other mineral oil of use, ucon oil brings.
Additive is the marrow of senior lubricant in modern age, correctly selects and rationally adds, and can improve its physicochemical property, gives new property to lubricating oil, or strengthens its certain performance originally had, and meets higher requirement.According to the quality and performance of lubricating oil requirements, meticulously selecting additive, carefully balance, carry out rational allocation, is the key ensureing quality of lubrication oil.General conventional additive has: viscosity index improver, pour point reducer, antioxidant, detergent-dispersant additive, friction negative catalyst, oiliness improver, extreme pressure agent, foam reducing composition, metal passivator, emulsifying agent, anticorrosive agent, rust-preventive agent, demulsifying agent etc.
CN1183237C disclose a kind of phosphorus content lower than 0.1% large diesel engine lubricating oil composition, comprising the mixture of ashless dispersant, neutral calcium phenylate, oil soluble high alkaline calcium sulfonate and overbased magnesium sulphonates, dialkyl disulfides zinc phosphate and ashless antioxidant, said composition has good high temperature detergency, resistance to abrasion and anti-oxidative stability.
Above-mentioned is will introduce the additives such as a small amount of high alkalinity sulfonic acid magnesium, high alkalinity sodium sulfonate or high alkalinity potassium sulfonate in the composition of metal detergent with calcium sulfonate with high base number, the high temperature detergency of introducing to composition of high alkalinity magnesium salts affects, and the introducing of high alkalinity sodium sulfonate or potassium can make the resistance to abrasion of lubricating oil composition decline, simultaneously, mountain is in the limitation of high alkalinity sodium sulfonate or sylvite antioxidation property, need to introduce more antioxidant, the economy of filling a prescription is affected.
USP6730638 discloses low ash content, engine starts oil lubricating that is low-phosphorous, low-sulfur is oily, the base oil of the sulphur content 300ppm of mountain primary amount, the boracic ashless dispersant of 0.5-10%, the friction improver containing aluminium of 0.05-1.5%, the at least one of 0.05-5.0% be selected from sulfonate, alkylphenol or salicylate metal detergent, the thiophosphoric acid zinc of 0.1-0.75%, the wherein purification agent of the preferred alkaline including earth metal of purification agent.
Prior art shows, and employing alkylsalicylate is metal detergent, can on the basis meeting properties, and the consumption of metal additive in reduction system meets oil product low-sulfur, low-phosphorous and low-ash requirement.But alkylsalicylate preparation process is complicated, and product cost is high.With sulfonic acid calcium salt and the composite modulation lubricating oil composition of alkylsalicylate, although combine the advantage of the two, in the storage of oil product and use procedure, additive easily becomes turbid or precipitates, and affects it and uses further.
Therefore, the progress of Lubricating Oil Technique is advanced to be very important.
