Description

A kind of diesel oil detergent saving fuel oil containing friction improver and preparation method thereof
Technical field
The present invention relates to a kind of fuel oil additive, particularly a kind of saving containing friction improver is fired Diesel oil detergent of oil and preparation method thereof.
Background technology
Low-sulfur, the appearance of ultra-low-sulphur diesel, although meet the requirement of environmental protection, but make diesel oil Self lubricity become extreme difference, result in dependence the oil transfer pump of diesel oil self-lubrication, high pressure fuel Jet pump excessive wear, the most therefore atomizer, piston gas ring and compression ring exist with upper bit Fretting wear phenomenon in various degree, greatly reduces service life and the combustion of fuel injection system Oil economy.Diesel fuel lubricity additive becomes the effective means solving this problem.Therefore at bavin On the basis of oil detersive, with the addition of diesel fuel lubricity agent, it is simply that in order to solve diesel oil in this respect Problem.Diesel oil detergent is with detergent-dispersant additive as host, and detergent-dispersant additive is efficient table Face activating agent, its polar group has the strongest adsorption capacity to established carbon distribution, deposit, Carbon distribution, deposit can be made gradually to loosen, and become little particle and be washed down, the most peace and quiet point Powder can stop little particle to form bulky grain and assemble on the metal surface, serves the work kept a public place clean With, engine work is served protective effect;Diesel fuel lubricity agent is using environment-friendly type combustion During material, by antifriction function, protect the normal operation of fuel injection system.
The present invention is directed to present derv fuel to meet the requirement of environmental protection, use low-sulfur, ultralow The oil transfer pump of diesel oil appearance of sulphur, jerk pump excessive wear, atomizer, piston gas There is fretting wear in various degree too in ring and compression ring, not only cause fuel oil to spray with upper bit Penetrate lifetime of system to shorten and make that fuel-oil atmozation is bad, the problems such as insufficient, oil consumption increasing of burning; By the application of multiple diesel fuel lubricity agent is found, being combined by suitable compounded diesel oil lubricant Diesel fuel additives, not only has the lubricant effect of excellence, at protection engine fuel injection system While, it is possible to play the effect saving fuel oil.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved is to provide A kind of diesel oil detergent saving fuel oil containing friction improver.
In order to reach above effect, the Mannich base of one of host detergent-dispersant additive is closed Become, and host and friction improver are screened.
(1) synthesis of Mannich base:
The toluene of the p-t-butyl phenol of 0.1mol with 120ml is added in still, adds 0.4g P-methyl benzenesulfonic acid, stir, by charge door add polyamines polyene in still, be passed through nitrogen Gas, is warming up to 80 DEG C, adds paraformaldehyde, is continuously heating to 120-130 DEG C, reacts 3h, Keep this temperature, after water knockout drum no longer divides water, after having reacted, stand 1h, with 50--60 DEG C Organic layer is washed 5 times by hot water, carries out decompression separation impurity and both obtained this product after filter filters.
In order to make additive lubricity of the present invention more preferable, the further Mannich synthesized by utilization Alkali detersive and aliphatic acid have synthesized existing detergent-dispersant performance and have had again the multiple-effect of excellent lubricity concurrently Additive.
By synthesized Mannich Base Detergent 0.05mol, toluene 60ml, p-methyl benzenesulfonic acid 0.2mol Add in reactor, be passed through nitrogen, be heated with stirring to 60 DEG C, by charge door, add ten Eight acid, are continuously heating to 80 DEG C, react 1.5h, stop reaction.By the decompression point of gained material From impurity, obtain Mannich alkaline 18 fatty acid amine diesel antiwear additive.
(2) selection of host: high-activity polyisobutene amine, polyetheramine etc. be clean intake valve, The effective additive in the position such as inlet and exhaust valve, atomizer, combustion chamber be Diesel engine temperature high, The position that carbon distribution is more difficult to remove, particularly general detersive heat decomposition temperature is difficult to meet diesel oil and sends out The requirement of motivation, the best to the combustion chamber cleaning performance of hot environment, therefore, detersive master In the selection of agent, except selecting polyetheramine, high activity polybutene amine, high-activity polyisobutene Beyond succimide, the Mannich base that can effectively clean combustion chamber is carried out emphasis choosing Select.The Mannich base that four kinds obtain with different amine synthesis is added in diesel oil as a certain amount of, profit Detergency test is carried out, to obtain the Mannich base of best results with crankcase coking plate.Bent axle The experimental condition that case coking plate uses is: oil temperature 120 DEG C, 310 DEG C of cokings of plate temperature, time 4h. Result of the test such as following table:
Test data (burnt weight/mg):
Sample 1-4 is respectively ethylenediamine, diethylenetriamine, triethylene tetramine, N, N-dimethyl The Mannich base that-1,3 propane diamine prepare.
Data show that the Mannich base using ethylenediamine as polar group is as diesel oil detergent effect More preferably.Determine select p-t-butyl phenol ethylenediamine as the present invention diesel oil detergent component it One.
(3) selection of friction improver: the kind of diesel oil friction improver have alcohol, ether, ester, Carboxylic acid and amine, acid amides isoreactivity compound, wherein with aliphatic acid, fatty acid ester wear resistence For excellent, aliphatic acid antiwear additive has certain acidity, and the corrosivity of diesel oil can be caused to improve, with Time promote carbon deposit and the generation etc. of greasy filth in Diesel engine, it is impossible to meet low-sulfur diesel-oil comprehensively and resist The requirement of mill property.And the abrasion resistance of long chain fatty acid mono ester compound is good, oil-soluble is good, body System is stable, the most significantly negatively affects diesel fuel characteristics, constitutes aliphatic acid and the carbon of alcohol of ester Chain is the longest, and its overall abrasion resistance is more excellent, therefore uses the long chain alkane ester of different molecular weight Compounds is selected by four ball frictional testing machines.
The wear resistence of diesel antiwear additive is different from lubricating oil, therefore evaluates diesel oil with four-ball tester wear-resistant Property must reduce test load, shorten the time, we use the operating condition of four-ball tester to be: (1) Load 15kg, (2) rotating speed 1500r/min, (3) time 30min, (4) temperature: normal temperature.
Test compares sample two kinds of wear resistences added under dose profile in diesel oil.Following table is examination Test result data.
Result of the test: (wear scar diameter/mm)
Addition μ g/g Sample 1 Sample 2 Sample 3 Sample 4
200 0.400 0.420 0.376 0.362
400 0.335 0.360 0.314 0.306
Sample 1-4 be respectively tetradecanoic acid monooctyl ester, hexadecanoic acid propyl ester, hexadecanoic acid monooctyl ester, Tetradecanoic acid monooctyl ester and hexadecanoic acid monooctyl ester 1:1 mixture, by result of the test it can be seen that Along with the increase of the alkyl chain length of the acid and alcohol constituting ester, antifriction quality improves, two kinds of ester mixing ratios Single ester wear resistence is more preferable, and therefore selecting sample 4 is anti-friction agent of the present invention.
