▎ 摘　　要

NOVELTY - A formaldehyde-removing purifying material capable of releasing fragrance comprises filter resin, graphene catalyst, auxiliary filler and manganese oxide fiber microsphere. The filter resin comprises PVC resin, plasticizer, organic acid, organic solvent, tromethamine and organic solvent. The auxiliary filler comprises fragrance filler, activated carbon particles, polybutylene succinate and thermoplastic. The fragrance filler comprises menthol powder, dried orange peel powder and zeolite powder. The graphene catalyst is zinc oxide, titanium dioxide and/or graphene oxide. The manganese oxide fiber microsphere is prepared by preparing flexible manganese oxide nanofiber film through electrostatic spinning, continuously unreeling flexible manganese oxide nanofiber film to conical cabin body, gathering flexible manganese oxide nanofiber film using twisting device in conical cabin body, twisting into manganese oxide fiber, cutting, putting into ball cabin body, and extruding. USE - The formaldehyde-removing purifying material capable of releasing fragrance used for removing formaldehyde (claimed). ADVANTAGE - The product is provided with manganese oxide capable of decomposing formaldehyde and set in form of microsphere, can be used for a long time, has good removing performance of formaldehyde at room temperature and good dust-proof ability, does not bring secondary pollution, removes peculiar smell, provides more active sites for catalytic decomposition of formaldehyde, and improves reaction effect of formaldehyde. DETAILED DESCRIPTION - A formaldehyde-removing purifying material capable of releasing fragrance comprises 20-40 pts. wt. filter resin, 1-10 pts. wt. graphene catalyst, 10-20 pts. wt. auxiliary filler and 5-10 pts. wt. manganese oxide fiber microsphere. The filter resin comprises 10-20 pts. wt. PVC resin, 1-5 pts. wt. plasticizer, 1-5 pts. wt. organic acid, 1-5 pts. wt. tromethamine and 10-20 pts. wt. organic solvent. The auxiliary filler comprises 5-10 pts. wt. fragrance filler, 5-10 pts. wt. activated carbon particles, 1-5 pts. wt. polybutylene succinate and 10-12 pts. wt. thermoplastic. The fragrance filler comprises 1-5 pts. wt. menthol powder, 1-5 pts. wt. dried orange peel powder and 1-5 pts. wt. zeolite powder. The graphene catalyst is zinc oxide, titanium dioxide and/or graphene oxide at weight ratio of 7-8:4-6:1. The manganese oxide fiber microsphere is prepared by preparing flexible manganese oxide nanofiber film by electrostatic spinning, continuously unreeling flexible manganese oxide nanofiber film to conical cabin body, gathering flexible manganese oxide nanofiber film through twisting device in conical cabin body, twisting into manganese oxide fiber, cutting, putting into ball cabin body, and extruding.
