NOVELTY - Nano-material comprises 20-70 pts. wt. AOP-KF solid alkali, 10-20 pts. wt. chlorine dioxide, 10-20 pts. wt. graphene powder, 10-20 pts. wt. large pore size silicon dioxide, 5-10 pts. wt. butyl titanate, 10-20 pts. wt. cyclohexane and 5-16 pts. wt. acrylate aqueous laminating adhesive. USE - As nano-material. ADVANTAGE - The material has strong adsorption force and long timeliness, and removes formaldehyde, benzene and other harmful substances in the air in a short time, and odor in the air. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the material involving (i) taking above-mentioned components, (ii) pouring AOP-KF solid alkali, chlorine dioxide and graphene powder in a planetary ball mill, using zircon grinding ball, controlling the revolution speed at 200 rpm, grinding the ball for 60 minutes and completely mixing the mixture to obtain a mixed powder, (iii) soaking large pore size silicon dioxide in a mixed solution of butyl titanate and cyclohexane, naturally hydrolyzing in air at room temperature for 12 hours, calcining in a muffle furnace at 600 degrees C for 2 hours, loading calcined titanium dioxide on the large pore size silicon dioxide in the form of a film to obtain the silicon dioxide-titanium dioxide carrier, (iv) adding the silicon dioxide-titanium dioxide carrier to a fluidized bed coating machine, coating the mixed solution of the obtained mixed powder and the acrylate aqueous laminating adhesive as a coating liquid, using bottom spray type, where the spraying speed is controlled at 4-5 ml/minute, the inlet frequency is controlled at 30-40Hz and the temperature in the fluidized bed coating machine is controlled at 30-40 degrees C and continuously drying the coated pellets in a fluidized bed for a period after completing coating and taking out to obtain the product.
