The invention provides a printable OLED electronic ink and a preparation method thereof. The electronic ink is prepared through following steps: an OLED organic light-emitting material which is loadedon aerogel and is prepared by taking silicate ester, an organic solvent, a silane coupling agent, a polymer monomer, an initiator, an OLED organic light-emitting material and water as raw materials;then a dispersion liquid is prepared by taking nano alloy particles, P-type nano metal oxide particles and an alcohol solvent as raw materials; and then mixing and stirring with an alkali metal complex doping material, a surface tension regulator, a viscosity regulator, a polar mixed solvent and an auxiliary solvent are carried out to obtain a finished product. The OLED material in the OLED electronic ink provided by the invention is good in dispersity, the physical properties such as viscosity, surface tension and boiling point of the composite ink can meet the requirements of existing ink-jet printing equipment, the
