Description

A kind of carbon on engine clean-out system and preparation method thereof
Technical field
The present invention relates to engine cleansing agent technical field, particularly relate to one and be applied to carbon on engine clean-out system.
Background technology
The fuel oil of engine chamber and air mixed afterfire, due to factors such as atomizing effects, the smog part produced after burning is discharged, and another part forms that carbon distribution is attached to be amassed on the object that temperature is lower as near swirler and nozzle, generates soft carbon distribution; When being deposited on high temp objects as some high-temperature zone wall of combustion chamber flame drum, formed hard carbon distribution by coking.The hard carbon distribution of combustion chamber is petroleum coke substantially, is to be formed by liquid phase fuel pyrolytic cracking pyrolytic deposition, and matter hard being difficult to removes.Hard carbon distribution often becomes the source of corrosion of combustion chamber with a small amount of sulfide.Conventional carbon cleaning method first uses apparatus as bamboo chip, and thick soot particles wiped off by steel disc, or blows large surperficial carbon deposit particle off by the method for blast.Soak with aviation kerosene, cleaning, then uses detergent washing greasy dirt, finally also cleans with a large amount of water again.Such carbon distribution method easily causes physical abuse to part, reduces work-ing life, and aero oil and water resource waste are comparatively large, and pollute the environment.
Real-life automobile maintenance industry needs the carbon distribution often removing fuel engines, and the method for existing decarbonizing is mainly scalped with perching knife after soaking carbon distribution with diesel oil, gasoline again, so both bothersome have the damage easily causing perching knife to engine part, also worry diesel oil in addition, disaster hidden-trouble that gasoline causes and dangerous, and it is also larger to environment with the greasy dirt that diesel oil, gasoline carbon remover are remaining, diesel oil, gasoline also not recoverable, had so not only been unfavorable for environmental protection but also not cost-saving.
The patent No. be 93118502.5 patent discloses one " self cleaning agent for IC engine oil pipes ".It mainly contains butanols, peregal, oleic acid, thanomin, ammoniacal liquor, kerosene, machine oil, glycol ether, water through mixing together.Then join in oil fuel and be made into mixing oil, run within the engine by such mixing oil and burn.This clean-out system reaches the object of removing grease, rust staining and carbon distribution to a certain extent, but containing ammoniacal liquor in formula, can cause corrosion to engine.
Application number be 200410051231.1 application discloses one " fuel engines carbon cleaning liquid ".It is mainly made up of potassium pyrophosphate, trisodium phosphate, sodium hydroxide, sodium carbonate, Starso, tensio-active agent, water.This clean-out system reaches the object of carbon remover to a certain extent, but this clean-out system emits by greasy dirt is become greasy filth, so just require that the engine compartment time must clean, otherwise greasy filth can block engine.At present, research and develop a large amount of carbon on engine clean-out systems, but most of clean-out system all exists has burn into a certain degree easily to block the shortcomings such as engine to engine part, develop a kind of there is high-efficiency cleaning, can reuse, carbon on engine clean-out system that environmental pollution is little just seems particularly necessary.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, the carbon on engine clean-out system that a class is new is provided, the advantages such as this clean-out system has high-efficiency cleaning, cost is low, environmental pollution is little, can reuse.
Carbon on engine clean-out system technical scheme of the present invention is be made up of following component by weight:
Tensio-active agent 5-20 part, permeate agent 5-10 part, dispersion agent 5-15 part, emulsifying agent 5-20 part, organic solvent is 35-80 part.
Tensio-active agent is any one in lauryl sulfosuccinic acid monoester disodium, fatty alcohol-polyoxyethylene ether (3) sulfosuccinic acid monoesters disodium MES, Coconut Fatty Acid Monoethanolamide sulfosuccinic acid monoesters disodium DMSS, single Tryfac 5573 MAP, Monododecylphosphate potassium MAPK, alcohol ether phosphate (AEO3, AEO9 phosphoric acid ester), lauryl alcohol phosphoric acid ester potassium (MAEPK), fatty alcohol-polyoxyethylene ether (EO=3) ammonium sulfate (AESA).
Described permeate agent is any one in sulfated castor oil, alkyl sodium sulfonate, alkyl sulfuric ester sodium, secondary alkyl sulphate sodium, a-sodium olefin sulfonate, sodium alkyl naphthalene sulfonate, succsinic acid alkyl ester sulfonate sodium, Igepon T, thionamic acid sodium, fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene.
Described dispersion agent is any one in sulphonated oil, alkyl or long chain base benzene sulfonic acid sodium salt, alkyl polyoxyethylene ether, sodium lignosulfonate, naphthalene sulfonic acidformaldehyde condensation product, oleoyl polyamine group carboxylate salt.
Described emulsifying agent is polyethenoxy ether class or polyoxypropylene ethers.
Described organic solvent is any one in ethanol, benzene, toluene, acetone, methylene dichloride, ethyl acetate.
By the emulsifiers dissolve of the permeate agent of the tensio-active agent of 5-20 part, 5-10 part, 5-20 part in the organic solvent of 35-80 part, stirring and dissolving is integrated in a kettle., be warmed up to 20-40 DEG C, add the dispersion agent of 5-15 part while stirring, temperature control is at 20-50 DEG C, isothermal reaction 30-100min, make it be separated into uniform liquid, namely abundant dissolving obtains engine cleansing agent.Beneficial effect of the present invention is:
(1) efficient: owing to the addition of tensio-active agent, permeate agent, dispersion agent, thus make clean-out system of the present invention can penetrate into quickly and efficiently carbon on engine inside and with carbon distribution effect, thus play the effect of cleaning.There is cleaning speed fast, effective, thoroughly can remove the advantage of combustion-chamber deposit.
(2) security: traditional clean-out system generally all with the addition of highly basic, and the present invention has abandoned adding of strong alkaline substance, so corrosion-free to engine components, to human-body safety.
(3) suitability: clean-out system of the present invention, owing to the addition of a large amount of dispersion agents, makes carbon distribution to lump, can be distributed in organic solvent, directly can be discharged to external engine, and need not disassemble engine can operate.
