Description
Technical field
The present invention relates to a kind of vehicle fuel oil additive, more particularly to a kind of methanol gasoline corrosion inhibitor.
Background technology
The corrosivity of methanol gasoline, methanol can typically contain acidic materials, and the suction of methanol in itself in process of production
It is water-based to be allowed to contain a small amount of moisture in storage process, while oxidation by air or bacterial fermentation can also be produced and a small amount of had
Machine acid, and, caused formaldehyde, formic acid etc. after methanol burning, more serious corrosion and abrasion shadow can be all produced to engine
Ring.The research of U.S. Ford company finds that after methanol gasoline, the iron content ratio in engine lubricating oil uses unleaded gas
Big 5.2 times, the main performance of abrasion of engine is the abrasion and corrosion of piston ring and cylinder wall, its main cause be methanol and its
Erosion of the radical reaction generation oxidation product (such as formic acid) to metal surface among burning.In addition, the evaporation latent heat of methanol is big,
Gasify bad and flow into cylinder wall, cause lubricating oil film be rinsed and caused by lubricating oil dilution and serious emulsification cause engine
The fretting wear of part.RIPP result of study shows that methanol gasoline has corrosiveness to the lead tin coating of automotive oil tank, such as contains
Moisture then can also produce corrosion to steel plate and welded still pipe, also have corrosiveness to the metals such as some copper, zinc, aluminium and its alloy.
The hydrophily methanol gasoline of methanol is easily separated in the presence of a small amount of moisture, influences storage and automobile is normally transported
Turn.The corrosivity of methanol itself can be equally shown in low-proportion methanol fuel.Ford Motor Company of the U.S. stops life within 1998
Produce methyl alcohol flexible fuel vehicle.Meanwhile allow in Europe, gasoline containing 3% methanol, but statistics is shown in fuel only
It with the addition of the methanol less than 0.1-0.5%.World fuel normal structure (The World Wide Fuel Charta, WWFC) is exhausted
To forbidding containing methanol in gasoline.Current technology can't solve methanol gasoline metal erosion sex chromosome mosaicism very well.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of prior art, there is provided a kind of methanol gasoline corrosion of good performance suppresses
Agent, to solve methanol gasoline to automobile dynamic system corrosion of metal, and reduce the etching problem to oil piping system rubber.
Methanol gasoline corrosion inhibitor provided by the invention, is made up of the component of following parts by weight：N-butanol 12~
15 parts, 4~5 parts of ethylal, 6~8 parts of propylene glycol methyl ether acetate, six 2~3 parts of polyethyleneglycol last of the ten Heavenly stems ethers, isomery
2~3 parts of alcohol APEO, 7~9 parts of lauric acid amide of ethanol, 4~6 parts of tert-butyl diphenyl chlorosilane, ethylene glycol 6~8
Part, 5~7 parts of 2- methyl -2- butanol.
As optimization, the methanol gasoline corrosion inhibitor, it is made up of the component of following parts by weight：13 parts of n-butanol,
4.5 parts of ethylal, 7 parts of propylene glycol methyl ether acetate, six 2.5 parts of polyethyleneglycol last of the ten Heavenly stems ethers, isomery alcohol polyoxyethylene
2.5 parts of ether, 8 parts of lauric acid amide of ethanol, 5 parts of tert-butyl diphenyl chlorosilane, 7 parts of ethylene glycol, 6 parts of 2- methyl -2- butanol.
The method for preparing methanol gasoline corrosion inhibitor of the present invention, comprises the following steps：
(1) by the lauric acid amide of ethanol of the parts by weight, tert-butyl diphenyl chlorosilane, ethylene glycol, 2- methyl-
2- butanol, uses magnetic stirrer stirring reaction 4~5 minutes under the conditions of 43~48 DEG C, after mixing, obtains A liquid；
(2) by the n-butanol, ethylal, propylene glycol methyl ether acetate of the parts by weight, at 52~55 DEG C
Under the conditions of, magnetic stirrer stirring reaction is used after mixing 10~15 minutes, obtain B liquid；
(3) by six 2.5 parts of the polyethyleneglycol last of the ten Heavenly stems ethers of A liquid, B liquid together with the parts by weight, isomeric alcohol polyethenoxy ether,
It is admixed together to use ultrasonic wave separating apparatus, under the conditions of 48~50 DEG C, ultrasonic disperse 15~25 minutes, produce.
Methanol gasoline corrosion inhibitor provided by the invention, by dispersant, antirust agent, rubber swelling inhibitor, corrosion inhibitor
Formed Deng composition.Act synergistically and protrude between each component；Methanol gasoline corrosion inhibitor provided by the invention is for reducing first
Alcohol gasoline is to automobile dynamic system corrosion of metal, and reduces obvious to the corrosiveness of oil piping system rubber.
Related experiment：Test material：Red copper：Meet the copper corrosion requirements of GB/T 5096；Brass：Meet in GB/T5231
The requirement of H70 copper；Cast iron chemical composition：Carbon mass fraction is 3.0%~3.3%, and the mass fraction of silicon is 1.8%~2.2%, iron
Surplus；20# steel：Meet GB 699 to require；Aluminium flake chemical composition：The mass fraction of silicon is 5.5%~6.5%, the quality point of copper
Number is 3.0%~4.0%, the mass fraction of iron<1.2%, the mass fraction of manganese is 0.8%, the mass fraction of magnesium for 0.1%~
0.5%, the mass fraction of nickel<0.5%, the mass fraction of zinc<1.0%, aluminium surplus；Tin piece：The mass fraction of tin is 29.0%
