NOVELTY - Odor purifying agent comprises 50-80 pts. wt. porous shell powder, 20-50 pts. wt. primary amino polyol, 0.05-0.1 pts. wt. graphene, 0.2-0.5 pts. wt. photocatalyst material, 0.1-0.5 pts. wt. antifungal agent and 0.1-1.0 pts. wt. nano-luminescent material. The photocatalyst material includes modified titanium dioxide and nano-silver. The modified titanium dioxide comprises a core body and a porous coating layer coated on the surface of the core body. The core body is nano-titania, the coating layer is nano-silica, and the surface of the coating layer has a multiple voids. USE - Odor purifying agent that is used for processing density board, plywood, blockboard, and bamboo template (claimed). ADVANTAGE - The odor purifying agent has an anti-counterfeiting function by introducing the nano luminescent material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an odor purifying agent, which involves: (a)weighing the component with specific portion;(b)adding the porous shell powder and primary amino polyol to the ball mill, grind into powder, where the time of ball milling is 20-40 minutes, until the fineness of the powder is 150-200 mesh to obtain first mixed powder;(c) adding the obtained mixed powder a together with graphene, photocatalyst material, antifungal agent and nano-luminescent material into the resonance mixer, and performing resonance treatment for 45-75 minute to obtain finished odor purifying agent.
