Abstract

The invention discloses a durable photocatalytic formaldehyde-removing ceramic tile which comprises a ceramic tile body, wherein the surface on the ceramic tile body is rough; an adhesive layer is arranged on the surface of the ceramic tile body; a photocatalyst functional layer is arranged on the surface, which is far away from the ceramic tile body, of the adhesive layer; the photocatalyst functional layer comprises a photocatalyst. The durable photocatalytic formaldehyde-removing ceramic tile disclosed by the invention has the effect of removing formaldehyde in a long time, and has excellent durability. Moreover, the process is simple and can be realized on the original ceramic tile production line, and the technology is easy to popularize; the various intrinsic indexes of the ceramic tile, such as gloss, color and the like, are not influenced. The invention further provides a preparation method of the durable photocatalytic formaldehyde-removing ceramic tile.

Description

technical field [0001] The invention relates to a tile, in particular to a durable photocatalytic formaldehyde removal tile and a preparation method thereof. Background technique [0002] Due to the wide use of chemically synthesized materials, indoor formaldehyde pollution has attracted more and more public attention. Nano-TiO 2 Photocatalytic technology is a high-tech formaldehyde removal technology that has gradually emerged in recent years. Under light conditions, it generates hydroxyl radicals with strong oxidative properties, which can almost non-selectively degrade all organic pollutants, such as formaldehyde and TVOC. As one of the building materials with large application area in the indoor environment, ceramic tiles, if nano-TiO 2 The combination of the formaldehyde removal function of photocatalytic materials will have great application value. At present, most of the technical patents for photocatalytic formaldehyde removal tiles are still on the smooth coating ...
