The invention relates to a silicone resin coating type platinum catalyst as well as a preparation method and application thereof. The silicone resin coating type platinum catalyst is core-shell microspheres which takes a platinum complex as a core and active component and crosslinking organic silicon resin as a coating layer and has the platinum catalysis hydrosilylation activity and is prepared by the following steps of by taking alkoxy silane as a raw material, performing secondary polymerization process with a W/O micro-emulsion to obtain the silicone resin coating type platinum catalyst. The silicone resin coating type platinum catalyst is uniform in particle size, good in stability, controllable in catalytic activity and suitable for application of single-component silica gel solidification system.
