Problems solved by technology

[0005] The technical problem addressed by the present invention is: in the prior art, the pollution caused by indoor and outdoor decoration boards cannot be efficiently and continuously removed, and the formaldehyde, organic pollutants, bacteria, mold and other pollutants carried in the decoration process cannot be effectively removed. Continuous removal; the residence needs long-term ventilation before living, but there will still be formaldehyde, organic pollutants and other harmful substances volatilized after living, causing long-term harm to the human body; the commonly used photocatalyst titanium dioxide can only be used at specific wavelengths It is used under certain conditions, and the scope of use is very narrow, so it cannot be better applied in decoration materials.

Abstract

The invention discloses a photocatalytic high-pressure decorative board and a preparation method thereof. The photocatalytic high-pressure decorative board is prepared through high-temperature and high-pressure one-time molding from a base board layer, an adhesive layer and a photocatalytic decorative layer. The photocatalytic decorative layer has a compound photocatalyst plate layer. The high-pressure decorative board has a photocatalytic function, so that the product can degrade various indoor harmful substances, such as formaldehyde and organic pollutants, generated during decoration process. The decorative board not only can avoid long-time ventilation of a newly-decorated room, but also can continuously degrade and remove the harmful substances generated from decorative materials. Thedecorative board avoids damage on human body and influence on environment due to the harmful substances generated from decorative materials and has excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of decorative plates. In particular, it relates to a photocatalytic high-voltage decorative plate and a preparation method thereof. Background technique [0002] At present, my country's interior decoration materials are mainly made of paints, coatings, soft decoration materials wallpaper, wall coverings and decorative panels. Among them, paints and coatings mostly contain volatile organic pollutants such as benzene and toluene, and heavy metals such as lead, mercury, chromium, and cadmium, which have great potential harm to the health of users or occupants, and also have great harm to the surrounding environment; Wallpapers and wall coverings have defects such as not waterproof, not moisture-proof, easy to fall off when the humidity is high, and easy to mold. Moreover, most of the glue used for pasting is a benzene solution of rubber adhesives. Volatile solvents have great harm to the human body. ; Most o...
