Abstract
Disclosed is an antibacterial product including at least one antibacterial part, wherein the antibacterial part includes a surface layer containing silver sintered under a nitrogen atmosphere or silver oxide sintered under an oxygen atmosphere. The antibacterial product prevents the proliferation of bacteria arising due to use thereof, kills bacteria, sterilizes and purifies contaminated water, and exhibits an antibacterial effect against harmful bacteria within at most 6 hr, and preferably an early antibacterial effect within 3 hr, especially 2 hr.
Claims17
An antibacterial product, comprising at least one antibacterial part,
- wherein the antibacterial part includes a sintered silver-containing surface layer which comprises a silver salt compound sintered under a nitrogen atmosphere,
- wherein the silver salt compound is selected from the group consisting of silver carbonate, silver chlorate, silver chloride, silver chromate, silver vanadate, silver manganate, silver nitrate, silver nitrite, silver perchlorate, silver phosphate, and silver acetate,
- wherein the nitrogen atmosphere is 99 to 100% nitrogen by volume at 440-1000° C.
A method of manufacturing an antibacterial product including at least one antibacterial part, comprising:
- (1) adding and dissolving a silver salt compound powder into water or a polar organic solvent to prepare a silver salt solution;
- (2) applying the silver salt solution on the antibacterial part;
- and
- (3) sintering the silver salt compound applied on the antibacterial part under a nitrogen atmosphere, thus forming a sintered silver-containing surface layer on the antibacterial part,
- wherein the silver salt compound is selected from the group consisting of silver carbonate, silver chlorate, silver chloride, silver chromate, silver vanadate, silver manganate, silver nitrate, silver nitrite, silver perchlorate, silver phosphate, and silver acetate,
- wherein the nitrogen atmosphere is 99 to 100% nitrogen by volume at 440-1000° C.
