Abstract

The invention discloses a preparation process of a water-based metal cold extrusion lubricant. The preparation process comprises the following steps: 1, adding 55-75 wt% of water and 1-5 wt% of a nonionic surfactant into a reaction kettle, and stirring until the nonionic surfactant is completely dissolved in water; and 2, firstly adding 5-10% of water-based stearate and 10-20% of tungsten disulfide into a solution obtained in step 1, heating, and continuously stirring, maintaining the temperature at 50-70 DEG C for 1 h, stopping heating, and after the solution is cooled, adding 10-15% by weight of a water-based interface lubricant, 0.5-1% by weight of a dispersing agent, 2-3% by weight of an antirust agent and 0.1-0.5 wt% of a defoaming agent to obtain the water-based metal cold extrusionlubricant. The water-based metal cold extrusion lubricant is a water-based cold extrusion coating, replaces a novel lubricating coating prepared through a phosphatization-saponification process, playsa role in protecting a mold and guaranteeing the size and the shape in the cold extrusion process, and is free of any waste water and waste gas pollution in the whole process.

Description

technical field [0001] The invention relates to the technical field of water-based lubricants, in particular to a preparation process and a use method of a water-based metal cold extrusion lubricant. Background technique [0002] In the metal cold extrusion process, the use of lubricants is very important. In the process of metal cold plastic forming, the resistance to tangential movement is generated between the contact surfaces when the metal to be processed and the mold move relative to each other, 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. The lubricant is used to reduce the friction resistance of the friction pair and slow down its wear. A firm and tough lubricating film is formed between them to achieve the purpose of reducing friction. If the lubrication of the surface does not meet the requirements, it will aggravate the wear of the mold, ...
