Emulsified oil for copper and copper alloy wire drawing and preparation method thereof

The invention discloses emulsified oil for copper and copper alloy wire drawing and a preparation method of the emulsified oil. The emulsified oil for copper and copper alloy wire drawing comprises the following components in percentage by weight: 3-15% of softened water, 0.8-1.5% of an anti-rust preservative, 3-5% of n-dodecyl amine, 6-14% of an anionic surfactant, 3-6% of a nonionic surfactant, 1-3% of organic alcohol amine, 4-7% of an extreme pressure agent, 7-10% of a lubricant, 2-4% of C14-C16 isomeric alcohol, 2-3% of a bactericide and the balance of water. The lubricating oil is prepared from the following components in percentage by weight: 1 to 3 percent of high-molecular-weight succinimide, 0.1 to 0.2 percent of siloxane type defoaming agent and 40 to 55 percent of base oil. The emulsified oil is simple in production and preparation process and easy to operate, raw materials are easy to obtain, harmful elements such as P, Cl and B are not contained, and the emulsified oil is a green and environment-
