Abstract

The invention relates to a corrosion inhibitor for alcohol ether fuel. A method for preparing the corrosion inhibitor comprises the following steps of: performing polymerization reaction of maleic anhydride and styrene by taking an alpha-methyl styrene dipolymer as a molecular weight regulator in a cyclohexanone solvent to obtain a maleic anhydride-styrene low polymer; adding water and polypropylene glycol 600, heating, distilling under reduced pressure and recovering cyclohexanone; and adding polypropylene glycol 2000 and ethylene glycol monobutyl ether to obtain the corrosion inhibitor. The corrosion inhibitor for the alcohol ether fuel has a simple preparation process, does not contain elements such as nitrogen, sulfur, phosphorus and the like which are harmful to environment, and is low in cost, high in intermiscibility with multiple oils and little in addition amount; and compared with the common corrosion inhibitor sold in markets, the corrosion inhibitor has an obvious anti-corrosion effect in various oils.
