The invention relates to a nano-silver-loaded microcrystal
bamboo charcoal ceramic bead and a preparation method thereof. The nano-silver-loaded microcrystal
bamboo charcoal ceramic bead is prepared from nano-silver and a microcrystal
bamboo charcoal ceramic bead by virtue of surface compounding, wherein the microcrystal bamboo
charcoal ceramic bead is prepared from the following components by weight percent: 30%-50% of bamboo
charcoal powder, 30%-40% of porous
nonmetal mineral
powder, 20%-30% of clay and 2%-5% of an
adhesive. According to the preparation method, the microcrystal bamboo
charcoal ceramic bead is coated with nano-silver, so that nano-silver has a strong support body, doped nano-structure silver is further formed, and the
catalytic efficiency of nano-silver is further improved; the microcrystal bamboo charcoal ceramic bead is high in structural strength and can
resist high temperature, so that the microcrystal bamboo charcoal ceramic bead can be regenerated by virtue of a
roasting manner after being used for a long time, and the adsorption capability and the
catalytic degradation and killing effects are recovered; compared with porous-ceramic-loaded nano-silver, the nano-silver-loaded microcrystal bamboo charcoal ceramic bead has relatively good effects in the aspects of
water quality purification,
air purification and the like, furthermore, the preparation method is simple, and the application is convenient.
