Abstract

The invention discloses a methanol fuel composite additive that is prepared from the following raw materials in percentage by mass: 20%-35% of polyether amine, 11%-25% of polyamine methyl polyisobutene phenol, 0.6%-5.0% of bis (benzotriazolyl) imidazoline Schiff base, 0.1%-3.0% of 2, 6-butylated hydroxytoluene, 1.0%-8.0% of glyceryl monooleate, 0.3%-3.0% of oleic acid diethanolamide borate, 0.5%-6.0% of diisooctyl sebacate and the balance of a cosolvent. The methanol fuel composite additive is good in synergistic effect, can effectively improve the cleaning performance, lubricating performanceand oxidation resistance of methanol fuel, the corrosion resistance of metal of an automobile oil way system and the swelling performance of rubber under the condition of low-dosage addition, and issimple in preparation process, easily available in raw materials, moderate in cost and good in environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry, and in particular relates to a composite methanol fuel additive. Background technique [0002] As the shortage of oil resources and environmental pollution become more and more prominent, actively seeking and developing clean alternative energy has become a key issue to promote my country's economic development. In the development and research of many new energy fuels, methanol fuel emerged as a new type of environmentally friendly fuel due to its excellent performance, and is currently the focus of the development of renewable energy in the world. The United States, the European Union, Brazil and other countries have used methanol fuel on a large scale. At present, my country's corresponding standards for methanol include GB / T 23510 vehicle fuel methanol, GB / T 23799 vehicle methanol gasoline M85, and local standards for methanol gasoline such as M15, M25, M30, and M50 succe...
