The invention discloses a transfer film waterborne mold releasing agent. The transfer film waterborne mold releasing agent is prepared from a component A, a component B, a de-foaming agent and a flatting agent, wherein the component A is prepared from methyl hydrogen silicone oil, vinyl silicone oil, an emulsifying agent, a pH (Potential of Hydrogen) regulator and de-ionized water; the component Bis prepared from a catalyst, the vinyl silicone oil, the emulsifying agent, the pH regulator and the de-ionized water. The invention further discloses a preparation method of the transfer film waterborne mold releasing agent. The transfer film waterborne mold releasing agent disclosed by the invention has the following advantages that 1, the transfer film waterborne mold releasing agent has a relatively low stripping force; 2, water is used as a dispersant and no organic solvent is released; the transfer film waterborne mold releasing agent is safe in transportation and utilization processes,is not combusted and does not explode and has no damages to human health and no pollution to the environment, and the solvent does not need to be recycled; 3, the transfer film waterborne mold releasing agent has relatively low viscosity (1cS to 10cS), and is diluted by the water or is directly utilized in a utilization process; the transfer film waterborne mold releasing agent is suitable for various coating manners and is simple and convenient to operate; 4, the curing temperature is moderate, the production efficiency is improved and safe production is realized.
