The invention discloses an anti-stain anti-corrosion antibacterial stainless steel plate. A preparation method of the anti-soil anti-corrosion antibacterial stainless steel plate comprises the following steps that (1) a stainless steel plate is subjected to mechanical polishing; (2) the stainless steel plate is subjected to caustic washing; (3) the stainless steel plate is subjected to acid washing; (4) the stainless steel plate is subjected to deactivation, specifically, the acid-washed stainless steel plate is placed in deactivation liquid and subjected to deactivation for 5-8 min on the condition that anode voltage is 4-6 volts; (5) the stainless steel plate is subjected to oxidation, specifically, the deactivated stainless steel plate is placed in film formation liquid at the temperature of 60-65 DEG C and treated by positive and negative alternate alternating current, and a layer of oxidation film of 300-400nm is formed on the surface of the stainless steel plate; (6) coatings are smeared on the stainless steel plate, specifically, the polymer coating and the antibacterial coating are smeared on the stainless steel plate; and (7) the stainless steel plate obtained from the step (6) is placed in distilled water and immersed for 6-8 min at the temperature of 75-85 DEG C, so that the anti-stain anti-corrosion antibacterial stainless steel plate is obtained. The preparation method is simple, and anti-stain, anti-corrosion and antibacterial functions of the prepared product are all excellent.
