NOVELTY - Online copper-plating water-soluble lubricating powder for welding wire and connecting wire, comprises 3-5 pts. wt. water absorbing agent, 10-20 pts. wt. heat removing agent, 35-42 pts. wt. calcium base, 5-12 pts. wt. lubricant, 5-10 pts. wt. auxiliary agent, 5-12 pts. wt. industrial soap powder, 8-10 pts. wt. talcum powder, 5-8 pts. wt. industrial alkali and 15-18 pts. wt. organic solvent type protective agent. USE - Online copper-plating water-soluble lubricating powder for welding wire and connecting wire ADVANTAGE - The lubricating powder reduces the friction between the interface, reduces force energy consumption when drawing, prevents adhesion of the metal mold wall caused by heating so as to reduce the energy consumption and temperature rise when drawing, prolongs the service life of the wire drawing mold, surfaces the quality of the product, and making the deformation uniform. The product has good lubricating rate, wide application and can provide good corrosion resistance and insulating performance to the welding wire in the process of connecting and pulling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing copper-plating water-soluble lubricating powder, which involves grinding a calcium-based material into 250-300-mesh powder, adding a lubricant, industrial soap powder, industrial alkali and a water absorbent into a ball mill charging basket, performing rolling ball milling for 30min, and continuously performing rolling ball milling for 8 min when the temperature is raised to 150 degrees Celsius to obtain mixed powder, sequentially adding the auxiliary agent and the heat removal agent into a barrel of a rolling ball mill, performing ball milling for 30 minutes, then adding the mixed powder into the barrel of the rolling ball mill, and performing rolling ball milling reaction for 30 minutes to obtain primary powder; mixing the primary powder, the talcum powder, the industrial alkali and the organic solvent type protective agent by a stirrer, heating the mixture for 40 minutes, and controlling the heating temperature at 50 degrees Celsius to obtain a finished product; and keeping the finished product for 40 minutes, cooling to room temperature, and fully grinding to obtain the finished lubricating powder.
