Abstract

The invention discloses an antibacterial and antiviral ferritic stainless steel and a preparation method thereof. According to the invention, multiform alloying silver elements and rare earth elements are distributed in a ferritic structure; the silver elements are naturally activated by the environment to form silver ions with different valence states, and the silver ions can act on bacteria and virus independently or in a combined mode; so that bacteria respiration is inhibited, or a virus structure is damaged; and therefore the bacteria and virus is killed; and the rare earth elements can increase the corrosion resistance of the steel and improve the antibacterial activity of the steel at the same time, and the requirements of kitchens and bathrooms, household appliances, household appliance parts, tableware, other public facilities and the like for stainless steel materials are met advantageously.

Description

technical field

[0001] The invention relates to broad-spectrum anti-virus and anti-bacteria iron and steel material technology, especially an antibacterial and poisonous ferritic stainless steel and its preparation method. By distributing polymorphic alloying silver elements and rare earth elements in the ferrite structure, the Silver elements are naturally activated by the environment into different valence silver ions, which can act on bacteria and viruses alone or in combination, inhibit bacterial respiration or destroy virus structures, thereby killing bacteria and viruses. The rare earth elements can increase the corrosion resistance of steel and at the same time improve The antibacterial activity of steel is beneficial to meet the demand for stainless steel materials such as kitchen and bathroom, household appliances, home appliance parts, tableware and other public facilities. Background technique

[0002] Bacteria and viruses are easily adsorbed on kitchens and bathr...
