The invention discloses copper rod complete-synthesis coarse-drawing lubricating fluid and a preparation method as well as a use method thereof. The copper rod complete-synthesis coarse-drawing lubricating fluid is prepared from the following components in parts by weight: 0.5-1 part of copper protectant, 3-5 parts of mixed emulsifier, 20-40 parts of water-based extreme pressure lubricant, 1-2 parts of boric acid, 2-5 parts of cholamine, 2-5 parts of monobutyl ether coupler, 0.5-1 part of hard water resistor, 0.01-0.1 part of defoamer, 0.01-0.1 part of triethanolamine borate antirust agent and 20-25 parts of distilled water; the copper rod complete-synthesis coarse-drawing lubricating fluid is used by being diluted with water according to a ratio of 1:5-20. The copper rod complete-synthesis coarse-drawing lubricating fluid has the advantages that the lubricating property, cooling property and oxidation resistance can be matched with cleaning property for a long term, stableness is achieved, and the service cycle is long.
