Abstract
The invention discloses a high-cleanness diesel lubricant which is formed by mixing the following components: 40-70 percent of C12-C20 unsaturated fatty acid monoester, 10-20 percent of C12-C18 saturated fatty acid, 10-20 percent of organic monoamine, 5-15 percent of dihydric alcohol, 5-10 percent of nitrate and 1-3 percent of ethylene-vinyl acetate copolymer. The high-cleanness diesel lubricant is used for improving the lubricating property of diesel, and has good low temperature fluidity and good lubricating property; the diesel has the condensation point of being less than -5 DEG C when the using amount of the high-cleanness diesel lubricant is 50-100ppm.
Description
Technical field
The present invention relates to a kind of diesel-dope, particularly a kind of additive for improvement of diesel fuel lubricity performance.
Background technology
Compared with petrol engine, diesel motor has the advantages such as efficiency is high, clean, durable, maintenance cost is low.Along with the raising that China requires the processed oil feature of environmental protection, in order to avoid in diesel engine vent gas, toxic substance is to the pollution of environment, and national compulsory ground reduces sulphur content in diesel oil, and within 2015, come into effect diesel oil state four standard, its sulphur content is 50mg/kg.
In diesel motor, diesel oil is fuel and lubricant.Reduce the sulphur content in diesel oil by hydrofining, the lubricity of diesel oil can be caused simultaneously to decline.If diesel fuel lubricity is too low, easily occur the adhesive wear of pump, pump performance quickly falls to the degree that cannot use subsequently, has had a strong impact on the performance and used life of engine.
Foreign petroleum company is a lot of about the research of non-acid type slip additive, once uses the oiliness additive of ester as low-sulfur diesel-oil of Carboxylic acid and alcohol synthesis, as glyceryl monooleate and caproic acid two isodecyl ester.Find in application, in this synthetic ester, add the low temperature flow improver for diesel fuel of 0.001 ~ 1%, can further improve the oilness of diesel oil.The domestic report also had about non-acid type slip additive, this lubricant is primarily of castor-oil plant grease composition, and molecular weight is large, characterization of molecules does not meet diesel oil character, and sticky valve, is unfavorable for burning, in diesel engine combusts process, produce black smoke, be not easily used as diesel fuel lubricity improving agent.
Summary of the invention
The object of this invention is to provide a kind of consumption few, condensation point is low, and low-temperature fluidity is good, the high-cleanness diesel oil lubricant that lubricity is good.
Diesel fuel lubricity agent of the present invention is made up of C12 ~ C20 unsaturated fatty acids acid monoester, C12 ~ C18 saturated fatty acid, unitary organic amine, dibasic alcohol, nitric ether and vinyl-vinyl acetate copolymer, and the mass percent of each constitutive material is:
C12 ~ C20 unsaturated fatty acids acid monoester 40 ~ 70% unitary organic amine 10 ~ 20%
C12 ~ C18 saturated fatty acid 10 ~ 20% dibasic alcohol 5 ~ 15%
Nitric ether 5 ~ 10% vinyl-vinyl acetate copolymer 1 ~ 3%.
Wherein, described unsaturated fatty acids acid monoester mainly refers to unsaturated fatty acid methyl ester or the ethyl ester of C12 ~ C20, as Linolenic acid methylester or ethyl ester, and methyl linoleate or ethyl ester; Described saturated fatty acid mainly refers to the saturated fatty acid of C12 ~ C18, as lauric acid, myristic acid, Palmiticacid, stearic acid; Described unitary organic amine mainly refers to the senior unitary organic amine of C8 ~ C18, as amino dodecane, tetradecy lamine, cetylamine, stearylamine; Described dibasic alcohol mainly refers to the dibasic alcohol of C2 ~ C6, as ethylene glycol, 1,3-PD, pentanediol etc.; Described nitric ether mainly refers to the nitric ether of C4 ~ C10, as cyclohexyl nitrate or isooctyl ester nitrate; The number-average molecular weight of described vinyl-vinyl acetate copolymer is 4000 ~ 8000.
The preparation method of diesel fuel lubricity agent of the present invention is: according to above-mentioned mass percent, adds C12 ~ C18 saturated fatty acid and unitary organic amine according to this in reaction vessel, within 2 hours, makes it fully react in 60 ~ 80 DEG C of stirrings; Add dibasic alcohol and C12 ~ C20 unsaturated fatty acids acid monoester more successively, stir after 20 ~ 30 minutes, add nitric ether and continue stirring 10 ~ 15 minutes, finally add vinyl-vinyl acetate copolymer, stir cooling and make material clear, obtain high-cleanness diesel oil lubricant.
The present invention is mainly used in the lubricity improving diesel oil, and consumption 50 ~ 100ppm, condensation point <-5 DEG C, low-temperature fluidity is good, and lubricity is good.
Join in GB diesel oil by the present invention with the addition of 50ppm, and do not add agent GB diesel oil and contrast, its properties is listed as follows.
