Abstract

The invention discloses a metal cold forming water-based lubricating agent which comprises the following components in percentage by weight: 71%-88% of water-based stearate, 1%-5% of a silane coupling agent, 0.1%-0.3% of an auxiliary lubricating agent, 0.5%-2% of a dispersing agent, 0.2%-0.5% of an antirusting agent, 0.1%-0.5% of a defoaming agent and 5%-27% of water, wherein the content sum of the components is 100%. The metal cold forming water-based lubricating agent disclosed by the invention has the advantages of safety, environmental friendliness and good lubricating effect. The preparation method of the metal cold forming water-based lubricating agent comprises the following steps: adding the water to a reaction kettle; sequentially adding the dispersing agent, the silane coupling agent and the water-based stearate under mechanical stirring; stirring for 10-20 minutes, and then adding the auxiliary lubricating agent; then stirring at a high speed for 20-60 minutes by utilizing a pipeline type shearing machine to completely emulsify and disperse materials inside the reaction kettle; and finally adding the defoaming agent and the antirusting agent, and mechanically stirring for 5-10 minutes to obtain the white water-based lubricating agent. The preparation method disclosed by the invention has the advantages of simple process flow and easiness for operation.

Description

Technical field [0001] The invention belongs to the technical field of lubricants for metal cold plastic forming, and in particular relates to a water-based lubricant for metal cold plastic forming and a preparation method thereof. The water-based lubricant is mainly used for cold extrusion, cold drawing and other cold forming of metal materials. . Background technique [0002] Lubrication and plastic forming are closely related. In the process of metal cold plastic forming, when the metal to be processed and the mold move relative to each other, the contact surface produces resistance that prevents tangential movement, that is, external friction. The existence of external friction will increase the force and energy required for processing, so it is necessary to lubricate the metal surface. If the lubrication of the surface does not meet the requirements, it will aggravate the wear of the mold and cause adhesion, scratches, scratches and other phenomena on the surface of the wo...
