Description

technical field [0001] The invention relates to a metal processing lubricating fluid, in particular to a water-based mobile phone battery case stamping and stretching forming lubricating liquid used for lubricating, cleaning, cooling and the like during the processing of the mobile phone battery case, a preparation method and a use method. Background technique [0002] The aluminum shell of the mobile phone battery is formed by rolling, stamping, and stretching the aluminum plate through a core-pulling die for many times. During the forming process, due to the large amount of deformation of the aluminum plate, a lot of heat and aluminum powder are generated, resulting in the surface of the aluminum shell. The temperature is extremely high. This requires that the lubricating oil used for stretching must have excellent cooling lubricity and settling performance on aluminum powder, so as to ensure that there are no scratches and strains on the surface of the workpiece; while tr...
