Said invention is extensive in application range, strong in germicidal action, stable in its property and harmless to human body, etc..
Description
The present invention relates to a kind of antibacterial agent, is a kind of compound silver series inorganic germifuge specifically.
At present, antibacterial agent can be divided into inorganic serial antibacterial agent and organic series antibacterial agent two big classes substantially.Inorganic antiseptic is safe in utilization, warm tolerance, durability, continuation are all better, but antibiotic late effect property, can not resemble rapid killing bacteria the organic antibacterial agent.Organic antibacterial agent safety, warm tolerance, stability are all than inorganic antiseptic difference, and facile hydrolysis decomposes or volatilization, and service life is short, but its sterilization prompt effect is that inorganic antiseptic can not be compared.Silver-series antibacterial agent is in occupation of leading status in inorganic antiseptic, and the scope of application is very extensive, and bactericidal effect is better than other inorganic antiseptics, and its major defect is that antibiotic durability, warm tolerance and ultraviolet color-changing etc. remain in problem.
Domestic by retrieval relevant patent documentation: the CN1140977A patent only relates to the coordination silver ion and ultra-fine grain silver powder is applied to medical device; CN1145343A, CN1151381A, CN1160686A all only relate to titanium dioxide is applied to fields such as pottery, enamel, glass with relevant antibacterial metals, all do not find to belong to silver-colored precipitating in photochemical catalyst (TiO with ultra-fine grain is complete
2) the two component antibacterial agents of surface composition photocatalysis sterilization and silver ion sterilization, also find to relate to and form the spacetabs type long-acting antibiotic agent among the coordination silver ion is adsorbed in adsorbent (zeolite).
The object of the present invention is to provide a kind of with ultra-fine grain argent precipitating in photochemical catalyst (TiO
2) the two component antibacterial agents of surface composition photocatalysis sterilization and silver ion sterilization and the coordination silver ion is adsorbed in adsorbent (zeolite) among form the spacetabs type long-acting antibiotic agent, two kinds of antibacterial agents are compound to be one, reach have wide spectrum, efficient, antibiotic, deodorizing, antifouling, self-cleaning function, reproducible compound silver series inorganic germifuge.
The objective of the invention is to be realized by following technical scheme: a kind of compound silver series inorganic germifuge is characterized in that by carrying silver-colored titanium dioxide semiconductor photochemical catalyst and zeolite with carrying silver is compound forms.
A kind of manufacture method of compound silver series inorganic germifuge is characterized in that being composited in grinding in ball grinder carrying silver-colored titanium dioxide semiconductor photochemical catalyst and zeolite with carrying silver and silicon sol solution; Said grinding is compound, is carrying a silver-colored titanium dioxide semiconductor photochemical catalyst 30～70%, and zeolite with carrying silver 40～60%, silicon sol solution be as the adhesive of complex, grinds to be composited in～12 hours; Said year silver-colored titanium dioxide semiconductor photochemical catalyst be by titanium dioxide through ultra tiny pulverizing, after vacuum outgas or the hydrogen reduction activation, form at the ultra-fine grain of its surperficial precipitating metallic state silver; Said zeolite with carrying silver is after the vacuum outgas activation processing, and absorption or ion exchange coordination silver ion form; The ultra tiny pulverizing of said year silver-colored titanium dioxide semiconductor photochemical catalyst adopts gas to pulverize or ball mill ultramicro powder process equipment processes, and average grain diameter is 0.1～5 micron; Said year silver-colored titanium dioxide semiconductor photochemical catalyst activation processing can adopt under condition of negative pressure to outgas, and less than 0.1 atmospheric pressure, 100 ℃ ± 50 ℃ degassing or 500 ℃ ± 100 ℃ of heating under the hydrogen condition down, reduces 3-5 hour; Said ultra-fine grain metallic state silver is that the high dispersive silver ion is attached to the ultra rme titanium dioxide surface, under alkali condition, PH is 9.5～10.5, becomes ultra-fine grain metallic state silver to be attached to titanium dioxide surface with hydrogen-peroxide reduction, and silver with the titanium dioxide ratio is: Ag: TiO
2=1: 50～100; Said activating zeolite is handled, and can adopt degasification activation processing under condition of negative pressure, and less than 0.1 atmospheric pressure, temperature is at 100 ℃ ± 50 ℃, and the degassing time is 5-7 hour; Said coordination silver ion is preferentially selected AgCl for use
