Methanol modifier as well as preparation method and application thereof

Abstract

The invention discloses a methanol modifier and a preparation method and application thereof, and belongs to the technical field of new energy. The methanol modifier comprises the following raw materials in parts by weight: 30-40 parts of a corrosion inhibitor, 10-20 parts of a clearing agent, 30-40 parts of low-carbon alcohol and 10-20 parts of vegetable oil, wherein the corrosion inhibitor is composed of benzotriazole, mercaptobenzothiazole, methylbenzotriazole, organosilicon and N,N-disalicylidene-1,2-propane diamine; the clearing agent is composed of polyisobutene amine and polyether amine, and the low-carbon alcohol is composed of isopropanol and isobutanol. The corrosion inhibitor disclosed by the invention can form a compact and firm protective film on the surface of metal to protect the metal from being corroded by atmosphere and water; the clearing agent does not generate deposits, and can remove original CCD and vegetable oil to reduce abrasion of machine parts. The methanol modifier can enable methanol fuel to have the effects of corrosion resistance, oxidation resistance, emulsification resistance, static electricity resistance, lubrication improvement, prevention of galling between a piston and an air cylinder and the like.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a methanol modifier and its preparation method and application. Background technique [0002] In the 1990s, global energy consumption increased sharply, and limited oil resources could not meet people's demand for energy. At the same time, the use of oil resources would emit a large amount of harmful substances into the atmosphere, resulting in environmental pollution. In order to alleviate the problem of tight oil supply and environmental pollution, countries around the world have begun to promote various alternative fuels. Among them, methanol is a green and clean energy. It has the highest efficiency and only emits water and carbon dioxide. It is the cleanest, most environmentally friendly and most promising fuel in the future. However, methanol is easily oxidized to produce formic acid when exposed to the air, which will swell the rubber gasket. Moreover, methanol is a d...

AI Technical Summary

Problems solved by technology

However, methanol is easily oxidized to produce formic acid when exposed to the air, which will swell the rubber gasket. Moreover, methanol is a dry substance with strong polarity and low lubrication coefficient. When it is used in automobile fuel, it is prone to corrosion, swelling, roughening, static electricity, etc. question

In addition, methanol is prone to static electricity during filling, loading and unloading, which leads to unsafe factors and limits its wide application as a clean energy source.
