Copper wire drawing agent and preparation method and application thereof

The invention relates to the technical field of metal processing aids, and provides a copper wire drawing agent as well as a preparation method and application thereof. The copper wire drawing agent provided by the invention is prepared from the following components: transformer oil, an emulsifier, polyalcohol amine, alkylphenol ethoxylates, fatty acid triglyceride, benzotriazole, a mildew preventive, organic silicon oil and diethylene glycol ether. According to the invention, the transformer oil is used as base oil, the cycloalkane content of the transformer oil is high, the formed emulsion system is stable, and the emulsion formed by mixing the obtained copper wire drawing agent with water is not easy to separate out oil and soap and has good stability. The surfactant and various assistants are compounded to obtain the copper wire drawing agent with excellent lubricating property, favorable cleaning property and long service life on the basis of ensuring the stability. The preparation method provided by the
