Abstract

The invention relates to an M30 methanol gasoline corrosion inhibitor which is prepared from the following components in parts by weight: 8 parts of petroleum ether, 12 parts of 2-chloro-4-nitryl imidazole, 16 parts of ethylene glycol monoethyl ether, 12 parts of trimethylolpropane mono allyl ether, 6 parts of creatine hexaphosphate, 8 parts of heptamethyldisilazane, 12 parts of diethoxyethylamine, 7 parts of zinc dialkyl dithiophosphate, 9 parts of dibenzofuran, 12 parts of octanol and 10 parts of glycol ether. The M30 methanol gasoline corrosion inhibitor provided by the invention is prepared from the following components such as a power promoter, a metal anti-wear reagent at extreme pressure, a rubber swelling inhibitor, a corrosion inhibitor and the like. The M30 methanol gasoline corrosion inhibitor has excellent antioxidant ability and corrosion resistant performance and effectively prevents automobile metals from being corroded in the using process, particularly corrosion on a cast iron generator.

Description

technical field [0001] The invention relates to a fuel oil additive for vehicles, in particular to an M30 methanol gasoline corrosion inhibitor. Background technique [0002] Methanol gasoline refers to a mixture of national standard gasoline (93#, 97#, etc.), methanol, and additives in a certain volume (mass) ratio and through strict procedures. It also includes mixtures of methanol, ethanol, n-propanol, n-butanol and isopropanol mixed with gasoline. [0003] The amount of methanol incorporated is generally 5% to 30%. The one mixed with 15% is the most, which is called M15 methanol gasoline. The anti-knock performance is good, the research octane number (RON) increases with the increase of the amount of methanol mixed, and the motor octane number (MON) is not affected. Combustion emissions are less toxic than regular leaded gasoline, and there is less carbon monoxide in the exhaust. Good combustion cleaning performance. However, general methanol gasoline is corrosive t...
