Organosilicon antimicrobial solution, organosilicon antimicrobial agent, antimicrobial glass, preparation method therefor and use thereof

A method of preparing a bactericidal glass, comprising the following steps of:

• coating a silicone bactericide on a glass surface, wherein the silicone bactericide is obtained by reacting an organosilicone bactericidal solution, comprising:
• by weight percentage,
• 30% to 65% of organosilicone quaternary ammonium salt;
• 10% to 40% of tetraethyl orthosilicate;
• 10% to 40% of organosilicone containing double bond;
• 5% to 20% of organosilicone containing epoxy group;
• 5% to 20% of methyltrimethoxysilane;
• and
• 0.1% to 3% of organic tin catalyst;
• wherein the organosilicone quaternary ammonium salt is at least one selected from the group consisting of methyldiethoxysilane ammonium chloride, N,N-dimethyl-N-octadecylaminopropyltrimethoxysilane ammonium chloride, (trimethoxysilylpropyl)octadecyldimethyl ammonium chloride, and 3-(trimethoxysilyl)propyldimethyldodecyl ammonium chloride at a temperature of 40° C. to 80° C. for 1 hour to 8 hours;
• and
• performing a baking treatment to the silicone bactericide coated on the glass surface to cure the silicone bactericide, thus obtaining the bactericidal glass.
