The invention provides a modified silicone oil type emulsion release agent which is prepared from the following raw materials in parts by weight: 25-40 parts by weight of phenyl vinyl silicone oil, 10-25 parts by weight of phenyl hydrogen-containing silicone oil, 2-8 parts by weight of an emulsifying agent, 0.005-0.015 part by weight of a catalyst, 0.002-0.01 part by weight of an inhibitor and 25-65 parts by weight of water. Compared with the prior art, the modified silicone oil type emulsion release agent provided by the invention has the advantages that the phenyl vinyl silicone oil and thephenyl hydrogen-containing silicone oil are taken as basic raw materials, the catalyst is added to promote the hydrosilylation, and the inhibitor is added to enable the modified silicone oil type emulsion release agent to have better storage stability; and in the using process of the modified silicone oil type emulsion release agent, a release agent protection layer can be formed on the surface ofa mold through cross-linking reaction, so that the release effect, high temperature resistance and durability of the mold can be improved.
