Preparation method of silver-copper metal colloid activated carbon antibacterial agent and organic artificial stone thereof
The invention discloses a preparation method of a silver-copper metal colloid activated carbon antibacterial agent and organic artificial stone thereof. The method comprises the following steps: S1) preparing a silver-copper nitric acid solution; S2) adding activated carbon micro-powder into the silver-copper nitric acid solution, and uniformly stirring; S3) pouring the activated carbon micro-powder adsorbed solution into a porcelain dish, and putting the porcelain dish into a drying oven for drying; S4) heating the activated carbon micro-powder adsorbed dry powder in a vacuum environment to aspecified temperature range for roasting; S5) adding hydrogen into a constant-temperature reduction sintering furnace for reduction reaction to prepare activated carbon micro-powder adsorbed roastedpowder; and S6) sieving the activated carbon micro-powder adsorbed roasted powder. The prepared silver-copper metal colloid activated carbon antibacterial agent has the characteristics of good heat resistance, broad-spectrum antibacterial property, excellent slow release property and the like. The invention further provides the organic artificial stone using the silver-copper metal colloid activated carbon antibacterial agent, and the prepared organic artificial stone is very excellent in antibacterial performance and antibacterial durability.
