NOVELTY - Preparation of decorative material involves (A) mixing 20-80 pts. wt. aqueous resin, 10-30 pts. wt. graphene powder, 10-50 pts. wt. negative ion powder to form slurry, (B) coating the slurry to the surface of the wall decorative material, (C) drying and (D) curing the surface coating layer. The aqueous resin is modified poly butadiene resin, epoxy resin, alkyl resin, amino resin, polyester resin grease, phenolic resin and/or acrylic resin. USE - Preparation of negative oxygen ion generating decoration material (claimed). ADVANTAGE - The preparation method consumes reduced amount of raw materials, is carried out with high efficiency, reduces the air pollution, purifies the air, promotes health of human body and the process is suitable for large scale production.
