(1) preparation of lubricating antiwear reinforcing agent: adding 20% of aluminum distearate, 20% of magnesium stearate, 12% of emulsifier and 3% of dispersant by weight into a high-speed stirring kettle, heating to 110 ℃ at 100 ℃, uniformly stirring and mixing at 200-300 rpm, cooling to 70-80 ℃, increasing the stirring speed to 4500-6000 rpm, stirring at high speed, slowly adding 45% of deionized water by weight proportion while stirring until the emulsion becomes pasty, keeping the rotating speed unchanged, continuously stirring for 20-30min, and stopping stirring to obtain the lubricating and antiwear enhancer;
(2) preparation of an auxiliary agent: adding 10% of ethylene stearic acid amide and 20% of ethylene bis stearic acid amide by weight, 5% of propylene glycol fatty acid ester, 3% of sodium silicate, 10% of oleyl alcohol polyoxyethylene ether, 51.5% of deionized water and 0.5% of sodium hydroxide into a high-pressure stirring kettle by weight percent, heating to 130-150 ℃, carrying out curing reaction for 0.5h under the pressure of 0.15-0.25MPa, and cooling to normal temperature to obtain the composite emulsion.
(3) Adding animal and vegetable oil, a lubricant, a surfactant, an antirust agent and an anticorrosive bactericide into the reaction kettle, and stirring for 0.5h to obtain a uniform emulsion; and (3) finally adding the emulsions prepared in the step (1) and the step (2), and stirring for 0.5h to obtain the required environment-friendly water-soluble stainless steel sheet punching oil.
