Abstract

The invention provides a decorative tile for improving the indoor air quality, and a preparation method thereof. The method comprises the following steps: adding a dispersant and graphene quantum dotsto a manganese salt solution, carrying out an oxidation reaction, dispersing the obtained product and a sodium hydroxide solution a chitosan / acetic acid solution, performing gelation to obtain composite xerogel particles, mixing the composite xerogel particles with an aqueous binder, coating the surface of a reinforced nonwoven fabric layer with the obtained mixture, drying the coated reinforcednonwoven fabric layer, and carrying out compression compounding on the dried coated reinforced nonwoven fabric layer and a micro-expanded polystyrene sheet to obtain the decorative tile for improvingthe indoor air quality. A three-dimensional network structure formed through loading nanometer manganese dioxide on the graphene quantum dots and performing gelation is placed between the reinforced nonwoven fabric layer and the micro-expanded polystyrene sheet to obtain the decorative tile, so the decorative tile has the characteristics of high specific surface area, high activity and strong catalytic ability, also has a long-lasting, safe and environmentally-friendly air purifying function, and can improve the air quality for a long time.

Description

technical field [0001] The invention relates to the field of air purification, in particular to the preparation of a decorative patch, in particular to a decorative patch for improving indoor air quality and a preparation method thereof. Background technique [0002] As people pay more and more attention to wall decoration, wall decoration materials are also following the market trend. At present, there are more and more varieties of decoration materials market. When the indoor wall surface can protect the wall, make the room beautiful and comfortable, it can also adjust the relative humidity of the indoor air, improve the living environment, and assist the wall to perform acoustic functions, such as sound absorption and reflection. The decorative effect of the interior wall is composed of three factors: the texture, lines, patterns and colors of the decoration materials. Common decorative materials for indoor walls include paint, plastic wallpaper, wall covering, marble wa...
