Abstract

The invention relates to a high-activity compound modified additive of methanol gasoline for an automobile. The additive is prepared from the following components in percentage by weight: 12% of ethanol as a solvent, 0.1% of 2-methyl-1-butanol as an antidetonant, 0.5% of sulfurized calcium alkyl as an adjustor, 1.5% of triethanolamine as an engine carbon deposition preventer and an anticorrosive agent, 2.5% of methylal as a combustion improver, 59% of normal butanol as an active mutual solvent, 0.1% of 3-methyl-1-butanol as a synthetic solvent, 10% of 2-methyl-1-propanol as a synthetic solvent, 10% of normal propyl alcohol as a synthetic solvent, 0.1% of ethyl tert butyl ether as an antidetonant, 2% of 1-phenyl-5-mercapto-tetrazole as a corrosion inhibitor, 1% of 2-mercapto benzimidazole as a corrosion inhibitor, 20.6% of nano TiO as a protective coating and 0.6% of 2, 6-ditert-butyl p-cresol as an antioxidant. The additive can be widely applied to additives of methanol and methanol motor gasoline.

Description

technical field [0001] The invention relates to a high-activity composite modified additive for methanol gasoline for automobiles, in particular to a high-activity composite modified additive for methanol gasoline for automobiles and its preparation process and application. Background technique [0002] With the increase of the global population and the continuous improvement of people's living standards, people have to endure the environmental pollution and energy pressure caused by the development of the automobile industry while enjoying the convenience brought by automobiles. Now that climate warming and frequent smog have caused confusion to people's lives and work, the "Action Plan for Air Pollution Prevention and Control" will be implemented to promote the prevention and control of air pollution, reduce vehicle exhaust emissions, protect the ecological environment, and crack the "ten-faced smog" It has become a common issue faced by our country and even the world.
