Problems solved by technology

If there are the following defects: (1) The application of composite recycled materials, paints, and coatings makes the indoor formaldehyde seriously exceed the standard and cannot be dissipated, which seriously endangers human health; (2) If the indoor humidity changes greatly in a short time, the indoor humidity is too high to cause mold and mites It is easy to reproduce in large numbers, or the indoor humidity is too low to cause dry throat and nose, dry and itchy skin, and flu-prone; (3) In addition, large areas of high-density walls can easily cause sound wave reflection, resulting in indoor listening conditions Very poor, resulting in restlessness; (4) At present, various interior functional decorations on the market can alleviate environmental problems to a certain extent, but due to the single function, the comprehensive effect is relatively low when used
However, at present, it has many functions such as adsorption and decomposition of harmful gases, moisture absorption and humidity control, antibacterial and anti-mildew, anti-algae and anti-condensation, sound absorption and dehydration, anti-allergic, anti-virus, far-infrared heating physiotherapy, etc., which can meet the multi-purpose of one material. Demanding functional decorative materials have not been reported yet

Abstract

The invention discloses a porous ceramic material with a composite function as well as a preparation method thereof. The porous ceramic material consists of an inorganic porous matrix and a composite-function film which is formed by spray-coating the surface of the inorganic porous matrix with composite-function sol; and the composite-function film is prepared from titanium dioxide, a functional additive and an acidic aqueous solution; the functional additive is selected from two or more complexes with different functions of zinc oxide nanoparticles / clusters, copper oxide nanoparticles / clusters, silver halide nanoparticles / clusters, bismuth vanadate nanoparticles / clusters, graphite-phase carbon nitride nanoparticles / clusters, silver / copper nanocrystals, gallic acid, polyvinyl alcohol and polyethylene phenol. The porous ceramic material with the composite function, which is provided by the invention, belongs to a solid-phase supported catalyst, overcomes the problems that a subparticlecatalyst is difficult to recover and troublesome to reuse and can realize adsorption and decomposition of organic pollutants such as dye and formaldehyde.

Description

technical field [0001] The invention relates to a nano-functional composite material processing technology, in particular to a multi-level porous ceramic material with composite function and a preparation method thereof. Background technique [0002] With the advancement of social technology and the improvement of manufacturing level, more and more new building materials have been applied. While obtaining convenient, cheap and comfortable living environment, the air quality and environmental quality in buildings are getting worse and worse. If there are the following defects: (1) The application of composite recycled materials, paints, and coatings makes the indoor formaldehyde seriously exceed the standard and cannot be dissipated, which seriously endangers human health; (2) If the indoor humidity changes greatly in a short time, the indoor humidity is too high to cause mold and mites It is easy to reproduce in large numbers, or the indoor humidity is too low to cause dry t...
