Description
Technical field
The present invention relates to lubricating oil Application Areas, specifically, relating to a kind of complete synthesis type bavin machine oil of the heavy-duty engine for working under harsh operating mode.
Background technology
At present, along with China's Abgasgesetz is increasingly strict, manufacturers of engines constantly adopts various new technology to meet more and more stricter Abgasgesetz to enable its engine.Such as, report has been had to adopt the technology such as DOC (oxide catalyst), DPF (particulate filter or trap), SCR (selective reduction catalyst), LNT (oxynitrides trap) and EGR (exhaust gas recirculation) to reduce the content of Exhaust emissions as far as possible at present.Meanwhile, for improving the power of diesel engine, diesel engine has widely used the technology such as straight spray, turbo-charging.The bavin machine oil that the use of these technology above-mentioned uses matched with diesel engine clean, dispersion, anti-oxidant, to resistance to wear etc. in propose strict requirement.
Bavin machine oil formed primarily of base oil and additive, and wherein the component of base oil accounts for more than 85% of whole content, and the quality of kind to whole bavin machine oil of base oil plays vital effect.Bavin machine oil mainly plays a part lubrication, cooling, clean and sealing within the engine.Oil film strength is that bavin machine oil carries out a very important index of lubrication, in the heavy loading work particularly under harsh operating mode, has very high requirement to the oil film strength of bavin machine oil.
The base oil of traditional bavin machine oil, mainly based on mineral oils base oil, is mainly divided into paraffinic base, intermediate base base oil and naphthenic base oils.Though paraffinic base and intermediate base base oil have good viscosity temperature characteristic, but shortcoming is that oxidation stability is low, pour point is high and viscosity is relatively little, if the heavy loading work bavin machine oil under applicable harsh operating mode will to be obtained for raw material with it, need to add a large amount of oxidation inhibitor, dispersion agent, anti-wear agent, pour point depressant and tackifier etc. wherein, the use of a large amount of additive can cause oil product progressively resolving and losing this function had in use.Though naphthenic base oils pour point is low, antioxidant property is good, but viscosity index is low, in use except needs add a large amount of detergent dispersant, anti-wear agent, viscosity increaser, also need to add viscosity index improver, and the fresh oil of general firm use is by the shearing action of engine friction pair, the viscosity index improver in oil product can be cut into small molecules, causes oil product kinematic viscosity obviously to decline; Thereafter along with the continuous increase of engine duration of service, oil product can occur to be oxidized and generate macromole colloid, add the catalyzed oxidation of wear metal and the effect of incomplete combustion product soot, oil product kinematic viscosity can be made slowly to go up, when being elevated to a certain degree, engine lubrication will be caused bad, and the possibility of generation accident increases.According to statistics, lubricating oil only accounts for 1% of vehicle operating cost, but the fault caused due to faulty lubrication accounts for 40% of total failare, so should use high-quality synthetic oil, minimizing accident is to create better economic benefit.
Also have the formula of some bavin machine oil to the addition of the synthetic oil of part to improve its product performance at present, but the heavy loading work that will be used under harsh operating mode also have problems.Although use the bavin machine oil formula of full synthetic oil also continuing to bring out, wherein only adopt the synthetic oil of single kind substantially, most of full synthetic oil bavin machine oil is based on pure poly-alpha olefins specifically.Poly-alpha olefins is nonpolar hydrocarbons, its oxidation susceptibility is not good, and the most additive used in bavin machine oil is polar material, thus cause the consistency of poly-alpha olefins and additive bad, additive is limited in use and in use easily separate out.All this kind all makes this area existing is that the bavin machine oil of raw material also cannot obtain gratifying performance with synthetic oil.
Given this, the present invention have developed the technical scheme of employing three kinds complete synthesis base oil preparation bavin machine oil, particularly employ high viscosity alkylnaphthalene base oil wherein, obtain a kind of and need add the novel complete synthesis type bavin machine oil of high-quality that a small amount of dispersion agent and oxygenant just can be applicable to the heavy loading work under harsh operating mode completely.This bavin machine oil efficiently solves existing most of bavin machine oil oil film strength deficiency for heavy-duty engine, fuel oil consumption forms Piston Carbon greatly, very easily, the powerful not lasting shortcoming of outputting power.
