Embodiment Construction

[0005] The present invention coats a layer of Fe on the basis of the original floor tiles 3+ —TiO 2 Thin film, after experimental research, the titanium dioxide in the film has reached the nanometer level, can carry out electronic excitation at a high capacity, play the role of oxidative decomposition of organic matter, and completely eliminate organic pollution. The film is prepared by the sol-gel method. Take 17ml of n-tetrabutyl titanate and 4.8ml of triethanolamine and dissolve them in 67.2ml of absolute ethanol, stir for 2 hours, then add 1ml of water and 10ml of ethanol and dope with 6.04×10 16 piece / cm 3 Fe 3+ The mixture was stirred for 30 minutes, repeatedly impregnated the floor tiles, and then kept at 100°C to form a gel, then heated to 540°C, dried and cooled to obtain Fe-coated 3+ —TiO 2 floor tiles. The iron ions doped in this invention can effectively reduce the ability required to stimulate electronic transitions to the visible light range, that is, u...

Abstract

The invention provides a floor tile of removing formaldehyde. The floor tile of removing the formaldehyde is characterized in that the floor tile is a basic material used at home, a layer of TiO2 thin film is loaded on a clean and dried floor tile by the adoption of an impregnation method, the thin film is prepared by the adoption of a sol-gel method, 17 ml tera-n-butyl titanate and 4.8 ml triethanolamine are dissolved in 67.2 ml absolute ethyl alcohol, the stirring is performed for 2 hours, then 1 ml water, 10 ml ethyl alcohol and a mixture doping 6.04*1016 Fe3<+> per cubic centimeter are added, the stirring is performed for 30 min, the floor tile is repeatedly impregnated, then gelatin is generated at 100 DEG C, later the floor tile is heated to 540 DEG C, the drying and the cooling are performed, and the floor tile coated with Fe3<+>-TiO2 is obtained. Through the above arrangement, the floor tile of removing the formaldehyde solves the problem of indoor formaldehyde pollution abatement, and the longtime clean-up effect can be achieved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a floor tile for removing formaldehyde. Background technique [0002] Indoor air pollution, especially formaldehyde pollution, has always been considered the number one killer that endangers human health. In the home environment, if the formaldehyde content exceeds the standard, it will directly affect human health. At present, the treatment of formaldehyde in the market is mainly carried out by physical or chemical methods. Although formaldehyde can be removed in a short period of time, because the emission time of formaldehyde is long, the method of removing formaldehyde in the market will lose its effectiveness after a long time. Now photocatalytic technology is widely mentioned in the treatment of indoor air, but because its excitation process requires high capacity, it needs to be excited under ultraviolet light, which limits its use.
