FULLY-SYNTHETIC DRAWING LIQUID FOR COARSE DRAWING OF COPPER AND USE METHOD THEREOF

摘要

The present invention relates to fully-synthetic drawing liquid for coarse drawing of copper and a use method thereof. The fully-synthetic drawing liquid for coarse drawing of copper comprises the following raw materials in parts by weight: 5-25 parts of a lubricant, 1-7 parts of a regulating acid, 4-11 parts of boric acid, 4-11 parts of organic alcohol amine, 4-11 parts of ethylene glycol, 4-11 parts of an antirust agent, 1-7 parts of a diethyleneglycol monobutyl ether coupling agent, 0.1-2 parts of a hard water resistant agent, 1-6 parts of a copper corrosion inhibitor T706, 0.01-0.16 part of an organic silicon defoamer, and 1-4 parts of a bactericide, with the balance being water. After the fully-synthetic drawing liquid for coarse drawing of copper prepared by the method is mixed with water according to a certain proportion, the effects of emulsified oil and microemulsion can be achieved when the lubricating property is tested on a German Microtap tapping torque machine, and the field actual use is completely free from problems; in the use process of the fully-synthetic drawing liquid for coarse drawing of copper, no floating oil problem exists, cleaning is easy, copper powder is easy to settle and filter, only subsequent addition is needed, replacement is not needed, no waste liquid is discharged, and environmental pollution is reduced.
