Abstract

The invention discloses oxidized paraffin and antirust wax and a preparation method thereof, and relates to the field of paraffin. The antirust wax comprises oxidized paraffin, an emulsifier, an antirust agent and water, and the emulsifier is at least one of sorbitan monooleate, lauryl sodium sulfate and fatty alcohol-polyoxyethylene ether; the antirust agent is at least one of cyclohexylamine stearate, alkenyl succinic acid and alpha-mercaptobenzothiazole; the oxidized paraffin is loaded with a Mn metal element through a carrier. The catalyst loaded with the active component Mn is added in the preparation process of the oxidized paraffin, the acid value and the soap value of the oxidized paraffin are effectively increased, the oxidized paraffin interacts with the specific emulsifier and the antirust agent, the emulsifier does not affect the anti-oxidation protection function of functional components, and meanwhile, the antirust agent and the oxidized paraffin cooperate with each other to achieve the anti-corrosion effect in a synergistic mode; and the antirust capability of metal in a humid and hot environment and an acid-base environment is improved, and the application prospect is expanded.
