preparation example Construction

[0056] The preparation method of the present invention: under normal temperature and normal pressure, the required components are respectively added into the mixer according to their volume parts through a flow pump; through thorough mixing, the desired inhibitor is obtained.

[0057] The polar group of the additive involved in the present invention is adsorbed on the surface of metals such as copper and aluminum, and the non-polar long chain forms a protective film on the metal surface to prevent the electrochemical corrosion of the metal by ions, and the protective film formed on the metal surface is also weakened. It prevents the corrosion of active sulfur in methanol fuel; some functional groups in the compound form complexes with certain strength with active materials such as Fe, and form a dense coating layer on the surface of steel to prevent alcohol gasoline from corroding active metals. At the same time, due to the addition of the rubber plasticizer, the swelling of th...

specific Embodiment approach 1

[0063] Under normal temperature, normal pressure, fireproof, explosion-proof, and static-free environment, proceed as follows:

[0064] (1) according to the volume portion of the present invention, be modulated into alcohol fuel additive;

[0065] (2) The additive and high-proportion methanol fuel, such as M85 and M100, are fully reconciled according to the volume ratio of 1 to 2:99 to 98, and a high-proportion methanol fuel with corrosion inhibition and swelling resistance can be obtained;

specific Embodiment approach 2

[0067] Under normal temperature, normal pressure, fireproof, explosion-proof, and static-free environment, proceed as follows:

[0068] (1) according to the ratio of the present invention, adjust the alcohol fuel additive;

[0069] (2) fully reconcile the added additive with the denatured methanol that does not have the anti-corrosion and swelling effect according to the volume ratio of 0.5~1:99.5~99;

[0070] (3) Fully mix the denatured fuel methanol prepared in step (2) with gasoline according to the required volume ratio, and then M5-M50 methanol gasoline can be prepared.

Abstract

The invention relates to alcohol fuel additive which has the advantages of anticorrosion of metals and inhibiting the swelling of rubber and solves the problems of metal corrosion and rubber swelling of the vehicle oil supply system and the transportation devices caused by the high proportion alcohol gasoline fuel; the alcohol fuel additive comprises the compositions calculated part by volume, including 5-8 portions of propargyl alcohol, 14-20 portions of malic acid diethyl ester, 8-14 portions of N-methyl morpholine and 18-26 portions of cyclohexane. The alcohol fuel additive has the advantages of inhibiting the metal corrosion effectively, moderating the swelling of the rubber and plastic parts caused by the alcohol fuel.

Description

technical field [0001] The invention relates to an alcohol fuel additive, in particular to an alcohol fuel additive for preventing metal corrosion and inhibiting rubber swelling. Background technique [0002] Alcohol fuel refers to gasoline containing a certain proportion of methanol or ethanol. Methanol generally contains acidic substances in the production process, and the water absorption of methanol itself makes it contain a small amount of water in the storage process. The presence of water in methanol fuel will activate the acid corrosion and electrochemical corrosion of metals. When there is no moisture in gasoline, the acid corrosion is very weak, mainly caused by active sulfides of copper corrosion; and when there is moisture in methanol fuel, it will cause acid ionization, which will intensify the acid corrosion of active metals. [0003] Methanol is corrosive to many metals in the engine fuel system and can corrode copper, iron, aluminum, lead, zinc, magnesium an...
