Abstract
The invention discloses the cleaning gasoline additives and preparing method. The additive comprises 7.1-9.0% alkylphenol amido, 14.5-18.0% polyisobutene succinamide, 1.5-2.5% methyl tert-butyl ether, 4.5-6.9% pyrrolidone, 6.3-9.7% diamine epoxypropane and 54-66% thinning oil. The additive is effective on cleaning charcoal and colloid of fuel spray nozzle and air inlet valve.
Description
Technical field
Prescription of the cleaning gasoline composite additive that the present invention relates to and preparation method thereof relates to the petrol engine decarbonizing, and prescription of the purification agent of minimizing noxious gas emission and preparation method thereof belongs to the purification agent technical field.
Background technology
The purification agent that prior art is used for the engine decarbonizing is a kind of tensio-active agent; this tensio-active agent can be in prime the fuel system; as nozzle; the metallic surface at positions such as intake valve forms protective membrane; thereby prevent that the settling that compound such as rare hydrocarbon forms owing to the high temperature oxidation condensation in the fuel oil from accumulating in the metallic surface; thereby play automatic cleaning prime the fuel system carburettor; nozzle; the settling at positions such as intake valve; and make them be in cleaner situation; allowing engine be under the good operating mode moves; and then reduce the vehicle exhaust hazardous emission, and can make automobile have the starting speed-raising fast; high-speed and low-noise; idling is steady; it is powerful to travel; advantages such as fuel-economizing.In the prior art, the purification agent that is used for gasoline mostly is the additive of simple function, mostly effective to the carbon deposit and the gelationus detergency of oil nozzle, and it is general even very little to carbon deposit and the peace and quiet effect of gelationus of intake valve PFI (port fuel injection device), when particularly running into inferior fuel, its effect descends greatly.
Summary of the invention
The objective of the invention is to solve above-mentioned the deficiencies in the prior art, purpose is to solve above-mentioned the deficiencies in the prior art exactly, provides the compound sky of a kind of novel clean gasoline to add agent and process for making thereof.Can effectively suppress the generation of colloid carbon deposit in petrol engine is used, being that engine is long-term keeps near best operating mode.A kind of cleaning gasoline composite additive prescription and preparation method thereof is provided, is used for the peace and quiet energy-conservation of petrol motor.
It is characterized in that the component of purification agent provided by the present invention is as follows:
The binder component weight percent:
Alkylphenol amine: 7.1% ~ 9.0%; Polyisobutene succinic diamide: 4.5% ~ 18.0%
Methyl tertiary butyl ether: 1.5% ~ 2.5%; Pyrrolidone: 4.5% ~ 6.9%
Diamino epoxy pronane: 6.3% ~ 9.7%; Thinning oil: 54% ~ 66%
Above raw material is commercially available.
Embodiment
Get 1/3rd thinning oil, after adding alkylphenol amine, polyisobutene succinic diamide, methyl tertiary butyl ether successively in proportion under 25 ℃～35 ℃ conditions, stir 45～60min and become A; Get 1/3rd thinning oil, become B after after adding pyrrolidone, diamino epoxy pronane polymkeric substance in proportion under 35 ℃～45 ℃ conditions, stirring 30～40min.
After stirring 15 ~ 20min, the thinning oil that adds surplus after A and B mixed successively in proportion makes finished product after filtration.
