Composite metal colloid inorganic antibacterial agent, preparation method and inorganic artificial stone thereof
The invention discloses a composite metal colloid inorganic antibacterial agent, a preparation method and inorganic artificial stone thereof. The composite metal colloid inorganic antibacterial agentcomprises hydroxyl zirconium phosphate micro-powder, silver atoms, copper atoms and nano titanium dioxide; specifically, micropores in the surface of the nano titanium dioxide adsorb the silver atom and copper atom colloids, and silver atom, copper atom and nano titanium dioxide colloids are adsorbed on the surface of the hydroxyl zirconium phosphate micro-powder; the silver atoms are used as an activating agent, the copper atoms are used as a to-be-activated antibacterial agent, and the nano titanium dioxide is used as an ultraviolet sterilization body. The copper atoms are oxidized into copper ions with antibacterial activity in an oxygen-containing wet environment. Antibacterial active substances contained in the composite metal colloid inorganic antibacterial agent are not easy to lose. The inorganic artificial stone prepared from the composite metal colloid inorganic antibacterial agent has the characteristics of good heat resistance, broad-spectrum antibacterial property, excellent slow release property, low procurement cost and the like, and has a better cost advantage.
