Abstract

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.

Description

technical field [0001] The technical field of the stainless steel material of the present invention relates to a stain-resistant, corrosion-resistant and antibacterial stainless steel plate and a preparation method thereof. Background technique [0002] Stainless steel is a silver-white alloy steel with excellent corrosion resistance, wear resistance, toughness and craftsmanship. Its excellent mechanical properties, good chemical stability and non-toxic properties make it widely used in aerospace, Marine, pharmaceutical, nuclear energy engineering, petrochemical and other aspects. In addition, stainless steel is also used for surface decoration in the construction industry, furniture appliances, kitchen equipment, automotive industry, office supplies, etc. Its beautiful natural surface provides beauty and cleanliness. However, during use, stainless steel materials are often exposed to corrosive liquids, such as acids and alkalis, which cause corrosion. Sometimes, the surfa...
