Metal colloid activated carbon antibacterial agent, and preparation method and inorganic artificial stone thereof
The invention discloses a metal colloid activated carbon antibacterial agent, and a preparation method and an inorganic artificial stone thereof. The metal colloid activated carbon antibacterial agentcomprises activated carbon micro-powder, silver atoms and copper atoms, the silver atoms are activators, and the copper atoms are a to-be-activated antibacterial agent; the silver atoms and the copper atoms are colloids adsorbed on the activated carbon micro-powder. And in an oxygen-containing wet environment, the silver atoms are oxidized into silver ions, and the copper atoms are oxidized intocopper ions with antibacterial activity. The dried metal colloid activated carbon antibacterial agent has good stability, and antibacterial active substances are not easy to lose. The invention also provides a preparation method of the metal colloid activated carbon antibacterial agent and an inorganic artificial stone using the metal colloid activated carbon antibacterial agent, and the metal colloid activated carbon antibacterial agent has the characteristics of good heat resistance, broad-spectrum antibacterial property, excellent slow release property, low purchasing cost and the like, andhas a better cost advantage.
本发明公开了一种金属胶体活性炭抗菌剂及其制备方法、及其无机人造石。所述金属胶体活性炭抗菌剂包括活性炭微粉、银原子和铜原子，所述银原子为活化剂，所述铜原子为待激活抗菌剂；所述银原子和铜原子均为吸附于活性炭微粉的胶体。含氧的湿润环境下，所述银原子被氧化为银离子，并将所述铜原子氧化为具有抗菌活性的铜离子。干燥的所述金属胶体活性炭抗菌剂具有良好的稳定性，抗菌活性物质不易流失。本发明还提出了所述的金属胶体活性炭抗菌剂的制备方法，以及使用所述的金属胶体活性炭抗菌剂的无机人造石，具有耐热性好、广谱抗菌、缓释性优良和采购成本低等特点，具有更加良好的成本优势。
