Problems solved by technology

[0003] The main components of methanol gasoline are composed of methanol and gasoline. Methanol has the following defects: 1) A small amount of acidic substances will be produced during the production process, and a small amount of organic acids will also be produced in contact with air; 3) During the combustion process, a small amount of acid and aldehyde substances may be produced
In the prior art, this defect is also changed by adding metal corrosion inhibitors, but the effect is not obvious

Abstract

The invention discloses a navigation alcohol fuel preservative anti-swelling additive for a vehicle, and solves the technical problem of corrosion of a metal part of an engine caused by existing methanol gasoline. The preservative anti-swelling additive is prepared from the following components in parts by weight: more than one reagent of 1 to 5 parts of 2-mercaptobenzothiazole, 1 to 5 parts of benzotriazole, 1 to 20 parts of xylene and 1 to 20 parts of alcohols, and at least more than two reagents of 1 to 20 parts of triethanolamine, 1 to 5 parts of trimer acid, 1 to 5 parts of calcium sulphonate and 1 to 20 parts of pyrazolone. The methanol gasoline which is prepared by using the navigation alcohol fuel preservative anti-swelling additive can inhibit the formation of an organic acid by external and internal water and navigation alcohol gasoline during manufacturing, storing and transporting processes, and can prevent the engine from being corroded, promote full combustion of the fuel and reduce the production of an acid and formaldehyde during a using process.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-swelling additive for aviation alcohol fuel for vehicles, which is added into methanol gasoline to prevent corrosion of engines and promote full combustion of fuel. The invention also relates to a preparation method of the aviation alcohol fuel anti-corrosion and anti-swelling additive for vehicles. Background technique [0002] With the rapid development of the automobile industry, the world is facing more serious problems such as oil resource shortage and environmental pollution. Therefore, vigorously developing economical, energy-saving and environmentally friendly alternative energy has become a significant and long-term strategic consideration. Methanol gasoline has become an ideal gasoline substitute due to its wide source, low production cost, good combustion effect, and less environmental pollution. [0003] The main components of methanol gasoline are composed of methanol and gasoline. Metha...
