Abstract
The invention discloses a release agent used for a wheel hub die-casting mold and a preparation method thereof. The preparation method comprises the steps that an organic solvent, glycerol, paraffin, silicone oil, polytetrafluoroethylene, talcum powder, triethanolamine and diatomite are mixed, heated, stirred and cooled, so that the release agent is obtained. The release agent used for the wheel hub die-casting mold and the preparation method thereof are capable of solving the problem that the lubrication performance is insufficient due to the fact that a thin film which is formed after a release agent used for a common wheel hub die-casting mold is coated is uneven.
