Abstract

The invention relates to a drawing fluid, in particular to a long-acting semi-emulsion copper drawing fluid. The drawing fluid is prepared by raw materials in parts by weight as follows: 18-20 parts of epoxidized soybean oil, 20-25 parts of trimellitate, 1-2 parts of pullulan, 1-2 parts of polyoxyethylene polyoxypropylene pentaerythritol ether, 4-5 parts of tween 80, 3-5 parts of glycerol monostearate, 2-3 parts of butylated hydroxyanisole, 0.5-1 part of molybdenum disulfide, 1-2 parts of isothiazolinone, 4-5 parts of auxiliaries and 800-1,000 parts of deionized water. The drawing fluid takes a mixture of the epoxidized soybean oil and the trimellitate as base oil, and additives such as tween 80, glycerol monostearate, isothiazolinone and the like are added, so that the oxidation stability is good, and oil separation, demulsification, rancidity and the like are not easy to cause; besides, the pullulan has certain film-forming property and can improve adhesiveness of the drawing fluid on the metal surface and reduce the friction coefficient; and the prepared drawing fluid is environment-friendly and long in service life, and the production cost is greatly saved.
