The invention relates to a PVC decorative material capable of purifying formaldehyde. The PVC decorative material capable of purifying the formaldehyde is prepared from the following raw materials inparts by weight: 102 parts of polyvinyl chloride, 17 parts of algae soil, 0.6 part of specific formaldehyde lytic enzyme crystals, 5 parts of alkalized black wattle bark fibers, 4 parts of carbonyl iron powder, 3 parts of tourmaline powder, 6 parts of nitrile rubber, 0.3 part of mullite, 1.5 parts of benzotriazole, 3 parts of chlorinated paraffin, 1.5 parts of aluminium silicate, 3 parts of quartzsand, 0.6 part of nano titanium dioxide and 4 parts of coconut shell-based activated carbon. The PVC decorative material is environment-friendly, by adding the specific formaldehyde lytic enzyme crystals, the tourmaline powder, the nano titanium dioxide, the coconut shell-based activated carbon and the like, the formaldehyde adsorption capability of the decorative material is improved, air is purified, a human body respiratory system is improved, and meanwhile, the PVC decorative material has the advantages of sterilization and mould proofing.
