Lubricating agent for preparing copper and copper alloy and using method of lubricating agent

The invention discloses a lubricant for preparing copper and copper alloy. The lubricant is characterized by comprising the following components in percentage by mass: 5-20% of talcum powder and/or carborundum powder, 2-5% of sodium polyacrylate, 1-5% of butylated hydroxyanisole, 1-5% of sodium carboxymethyl cellulose, 1-3% of sodium dinaphthyl methane disulfonate and the balance of beef tallow. By adding talcum powder and/or carborundum, sodium polyacrylate, butylated hydroxyanisole, sodium carboxymethyl cellulose, sodium dinaphthyl methane disulfonate and beef tallow and controlling the respective addition amounts, the lubricating oil has the advantages of high adhesive force, thick oil film, high heat dissipation performance, small wire drawing friction resistance and improved surface smoothness on the surface of a copper material. And meanwhile, the color difference problem on the surface of the bar can be solved, the surface quality of the copper material is improved, and the technical effect of a mirror
