Environment-friendly high-pressure decorative plate

Abstract

Disclosed is an environment-friendly high-pressure decorative plate. The environment-friendly high-pressure decorative plate comprises a base layer, a reinforcing layer and a decorative layer. The base layer is made of kraft paper and impregnated with modified phenolic resin. The reinforcing layer is made of chemical fibers and impregnated with modified phenolic resin. The decorative layer is impregnated with a mixed material of modified melamine-formaldehyde resin and a photocatalyst material, wherein in the mixed material of the modified melamine-formaldehyde resin and the photocatalyst material, the weight percentage of the modified melamine-formaldehyde resin is 40-60%, the weight percentage of the photocatalyst material is 20-30%, and the balance is a solvent. The modified melamine-formaldehyde resin is prepared from a modifier and a reacted melamine and formaldehyde resin through mixed modification. The photocatalyst material is one or more of TiO2, ZnO, CdS, WO3, Fe2O3, PbS, SnO2, ZnS, SrTiO3 and SiO2. According to the environment-friendly high-pressure decorative plate, the indoor pollutants can be subjected to photocatalytic reaction through catalysis of the photocatalystmaterial, so that the pollutants can be rapidly and effectively decomposed and destroyed.

Description

technical field [0001] The invention relates to the technical field of plate manufacturing, in particular to an environment-friendly high-pressure decorative plate. Background technique [0002] In recent years, in some newly built and renovated high-air-tight residential and office buildings, people continue to experience eye, nose and throat irritation, tearing eyes, fatigue, memory loss, headache, fever, asthma, hypersensitivity pneumonitis, Symptoms such as dermatitis, this is the so-called "building syndrome" and "chemical allergy". [0003] And the main cause of causing the above-mentioned diseases is that the biological pollutants and chemical pollutants in the indoor air are full of indoors and are not easy to disperse and cause. Biological pollutants such as bacteria, fungi, and dust mites, while chemical pollutants originate from new building materials or other household items, such as: sulfur oxides, nitrogen oxides, carbon monoxide, cigarette smoke, formaldehyde...

AI Technical Summary

Problems solved by technology

However, the adsorption of pollutants is relatively weak and the adsorbent is easy to reach adsorption saturation, which affects the subsequent adsorption efficiency of pollutants, so it needs to be replaced or regenerated regularly, which makes the subsequent treatment cost relatively higher

In addition, the use of air purifiers consumes more energy and takes up indoor space.
