The invention belongs to the technical field of a chemical preparation, and relates to an alcohol mixing solvent. According to a recipe, the alcohol mixing solvent is prepared from 86.9 to 88.9 weight percent of absolute ethyl alcohol, 9.5 to 10.9 weight percent of isopropyl alcohol and the balance of butanone. Compared with ordinary absolute ethyl alcohol, the alcohol mixing solvent has the advantages that the solubility on a capacitance welding material is higher; the dissolution efficiency is doubled; the alcohol mixing solvent is very suitable for precise purposes of electronic industry and the like; good market competitiveness is realized.
