Abstract
The present invention relates to a cleaning agent for a fuel oil system, which is prepared from 5 to 20% of macromolecular detergent dispersant, 10 to 30% of carrying oil, 5 to 20% of dehydrator, 15 to 35% of polar solvent and 30 to 65% of diluting agent, wherein the macromolecular detergent dispersant can be one of polyisobutene amine, polyether amine, poly alkylphenol, alkyl group polyurethane and polyisobutylene succinimide, the carrying oil is one of alkyl group polypropyleneglycol ether, alkyl group polytetramethylene glycol ether, mechanical oil, base oil, liquid paraffin and vegetable oil, the dehydrator is one of or two of nonyl phenol polyoxyethylene ether, octadecy l polyoxyethylene ether, peregal, dodecyl alcohol amide, Tween-80 and Span-80, and the polar solvent is one or a plurality of isopropanol, isobutanol, ethylene glycol monomethyl ether and ethylene glycol monobutyl ether. The present invention has the advantages of no corrosion to metal, high stability, convenience, rapidness and no delay to normal running of automobiles.
Description
(1), technical field
The invention belongs to a kind of gasoline car cleaning agent for fuel oil system.
(2), background technology
Because the oxidation products of impurity, external moisture and gasoline olefin in the gasoline can deposit to positions such as fuel tank, oil pipe, carburettor gradually, sending out imperfect combustion product in the collaborating of cycle gas, malleation air inlet of merit machine simultaneously can be deposited on carburettor, intake manifold, intake valve, combustion chamber and form colloid, the oxidation step of going forward side by side is a carbon deposit, and these settlings will cause and mix that combustion gas departs from ideal value, quickens that the air inlet of metal parts burn into is smooth, the combustion chamber heat-conducting piece reduces, compression ratio increases, pre-ignition, increase oil consumption, tail gas raise, degradation defective under the power.Thus, people adopt diverse ways to clean the settling of prime the fuel system.Conventional method is manually to scrub after automobile is taken apart or soak with aqueous alkali, and this will cause metallic corrosion and destroy part inherent precision-fit, and the cleaning interval is long, and the cost height is also unfavorable to repairman's health.Another kind of purging method is to use the peripheral equipment wash cycles, and its shortcoming spends height exactly, needs special-purpose cleaning equipment, and it is incomplete to clean the position.The third method is to utilize the prime the fuel system cleaning machine to exempt from demolition clean.Chinese patent CN1035562, CN1182781, the disclosed prime the fuel system of CN1106060 are cleaned and mainly are made up of alcohols, alkyl amine, low-molecular-weight surfactant, alcohol ether, water, thinner etc.These products have following shortcoming: at first because the existence of water, strong alkaline substance causes corrosion of metal easily; Secondly because the existence of water, product stability is poor, and layering easily adds behind the gasoline also less stable.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of cleaning agent for fuel oil system, it does not only have corrosion to metal, and good stability, and the wash clean that can effectively prime the fuel system settling everywhere be disappeared are convenient and swift, do not delay the normal operation of automobile.
The present invention solves the technical scheme that its technical problem takes: it comprises the polymer detergent-dispersant additive, carries oil, water-removal agent, polar solvent, thinner, its mass ratio is: polymer detergent-dispersant additive: 5-20%, carry oil: 10-30%, water-removal agent: 5-20%, utmost point spare solvent: 15-35%, thinner: 30-65%, described polymer detergent-dispersant additive can be a kind of in PIBA, polyetheramine, poly-alkylphenol, alkyl urethane, the polyisobutenyl succinimide; Carry a kind of in the alkyl polypropylene glycol ether, alkyl polytetramethylene glycol ether, machinery oil, base oil, whiteruss, vegetables oil of oil; Water-removal agent is one or both among polyoxyethylene nonylphenol ether, octadecyl Soxylat A 25-7, peregal, dodecanolyacylamine, Tween-80, the Span-80; Polar solvent is a kind of in Virahol, isopropylcarbinol, ethylene glycol monomethyl ether, the ethylene glycol monobutyl ether or several; Thinner is a kind of in gasoline, dimethylbenzene, 200# solvent oil, kerosene, the turps.
It does not only have corrosion to metal, good stability, and the wash clean that can effectively prime the fuel system settling everywhere be disappeared, when eliminating colloid, carbon deposit, also possess the function of eliminating moisture in the oil circuit, convenient and swift, do not delay the normal operation of automobile, driver oneself just can clean.
(4), embodiment
The present invention includes the polymer detergent-dispersant additive, carry oil, water-removal agent, polar solvent, thinner, its mass ratio is: polymer detergent-dispersant additive: 5-20%, carry oil: 10-30%, water-removal agent: 5-20%, polar solvent: 15-35%, thinner: 30-65%.
Wherein the polymer detergent-dispersant additive plays significant feature, settling can be distributed in the gasoline, and it can be a kind of in PIBA, polyetheramine, poly-alkylphenol, alkyl urethane, the polyisobutenyl succinimide, and its mass percent is 5-20%.
Carry oil and assist the polymer detergent-dispersant additive to play a role in hot metal surface, it can be a kind of in alkyl polypropylene glycol ether, alkyl polytetramethylene glycol ether, machinery oil, base oil, whiteruss, the vegetables oil, and its mass percent is 10-30%.
Water-removal agent is used for the free-water in the solubilising emulsion gasoline, thereby water is formed ice crystal when slowing down corrosion and preventing winter.Water-removal agent can be among polyoxyethylene nonylphenol ether, octadecyl Soxylat A 25-7, peregal, dodecanolyacylamine, Tween-80, the Span-8 one or both, and its mass surface proportion by subtraction is 5-20%.
Polar solvent can be a kind of in Virahol, isopropylcarbinol, ethylene glycol monomethyl ether, the ethylene glycol monobutyl ether or several, and its mass percent is 15-35%.
Thinner can be a kind of in gasoline, dimethylbenzene, 200# solvent oil, kerosene, the turps, and its mass percent is 30-65%.
Provide two embodiment below.
Embodiment 1: the present invention includes PIBA: 6%, and the octadecyl polypropylene glycol ether: 12%, peregal-15:6%, isopropylcarbinol: 18%, 200# solvent oil: 58%.
Embodiment 2: the present invention includes polybutylene succinimide: 8%, and purification paraffin: 12%, Tween-80:14%, ethylene glycol monomethyl ether: 30%, dimethylbenzene: 36%.
Production method: polymer detergent-dispersant additive, carrier oil are used for thinner, again water-removal agent are dissolved in the polar solvent, both are mixed get final product again.To just can automatically prime the fuel system be cleaned up in the ratio adding fuel tank of the present invention in 0.5-1%.
