Formaldehyde removing wallpaper, preparation method of wallpaper, and formaldehyde purifying method

Abstract

The invention provides formaldehyde removing wallpaper. A conducting layer is positioned on a substrate layer, and is connected with a lead, the lead is connected with a power supplying device, a semiconductor refrigerating layer is positioned on the conducting layer, a photocatalysis titanium dioxide layer is positioned on the semiconductor refrigerating layer, ultraviolet LED (Light Emitting Diode) lamps arranged in an array manner are embedded in the semiconductor refrigerating layer and the photocatalysis titanium dioxide layer, and are connected with the conducting layer; active carbon particles are distributed on the photocatalysis titanium dioxide layer. According to the formaldehyde wallpaper, air heat flow is formed by using the semiconductor refrigerating layer, the adsorption of formaldehyde is accelerated; the adsorbed formaldehyde is decomposed into carbon dioxide and water by using the photocatalysis titanium dioxide layer, and thus the formaldehyde removing wallpaper is environmental-friendly and sanitary, and can be recycled. In addition, the formaldehyde removing wallpaper is capable of manually designing an arrangement mode of the active carbon particles, and is capable of playing an effect of decorating a room. Therefore, the formaldehyde removing wallpaper is high in formaldehyde removing efficiency, can be recycled, is attractive and elegant, is capable of decorating the room, and has a potential application value.

Description

technical field [0001] The invention relates to the field of formaldehyde purification, in particular to a formaldehyde-removing wallpaper, a preparation method thereof and a formaldehyde purification method. Background technique [0002] There is generally an unpleasant smell in a newly renovated house, which mainly comes from formaldehyde released from furniture, sofas, paints, etc. Formaldehyde is a gas with a strong pungent smell. A certain concentration of formaldehyde can cause damage to the human nervous system, lungs, liver and other organs. Generally speaking, the release cycle of formaldehyde in furniture is as long as 5 to 10 years. If you live at home for a long time and do not remove formaldehyde in time, it will inevitably affect people's health. [0003] At present, the commonly used methods for removing formaldehyde at home include ventilation method, plant absorption method, activated carbon adsorption method, chemical reagent purification method, etc. Ven...

AI Technical Summary

Problems solved by technology

Ventilation method is a very good method, which can effectively reduce the indoor formaldehyde content, but when sleeping at night, doors and windows are often closed, which limits the use of ventilation method; the absorption effect of plant absorption method is not very good; activated carbon adsorption The method can absorb formaldehyde, but it cannot remove it, and after a certain period of time, the adsorption effect of activated carbon will be greatly reduced; the chemical reagent purification method is complicated to operate, and there is a risk of secondary pollution, and it cannot be used every day, which limits Its purification effect
