Embodiment 1
[0025] The photocatalytic air purification decorative panel was prepared according to the following steps:
[0026] 1) In parts by weight, 6 parts of shell powder with a particle size range of less than 50um, 3 parts of activated carbon powder with a particle size range of less than 100um, and 5 parts of nano-silicon dioxide are fully mixed and stirred evenly, and 0.5 parts of silane coupling agent are added, and then stirred for 60 minutes. Prepare the mixture powder A;
[0027] 2) In parts by weight, add 15 parts of silica sol, 0.8 parts of carboxymethyl cellulose, 0.3 parts of silane coupling agent, 0.06 parts of silicone surfactant, 0.6 parts of aluminum powder with a particle size of less than 20um, and a mass fraction of 30% hydrogen peroxide 3 parts were mixed and stirred at 90°C for 120 min; 6 parts of anatase crystal nano-titanium dioxide powder were added under stirring to prepare Adhesive B; the mass fraction of silicon dioxide in the silica sol was 30%.

Abstract
The invention discloses a preparation method of a photocatalytic air purification decorative board, comprising the following steps: 1) fully mixing 2-10 parts of shell powder, 0.1-5 parts of activated carbon powder, and 2-8 parts of light guide agent in parts by weight Stir evenly, add 0.1-1 part of silane coupling agent, and stir for 30-60 minutes to obtain mixture powder A; 2) Add 10-20 parts of silica sol and 0.5-2 parts of water-soluble cellulose in parts by weight , 0.1-0.5 parts of silane coupling agent, 0.01-1 part of silicone surfactant, 0.1-2 parts of aluminum powder, 0.1-5 parts of hydrogen peroxide, mixed and stirred at 40-100°C for 60-120min; 1-6 parts of titanium dioxide powder is used to prepare adhesive B; the invention has the advantages of porous adsorption, high photocatalytic efficiency, and strong adhesion between nano titanium dioxide and the base layer.
Description
technical field [0001] The invention relates to the technical field of air purification materials, in particular to a preparation method of a photocatalytic air purification decorative board. Background technique [0002] Due to the influence of furniture decoration or space structure, the indoor air environment of the building makes the air fluidity of the indoor local environment poor, the air is easy to pollute, and bacteria and viruses are easy to spread; if it encounters humid weather, it is easier to breed bacteria, viruses and other microorganisms, and produce various ammonia Gas, hydrogen sulfide, sulfide, nitrogen oxides and other odorous gas substances, as well as harmful substances such as formaldehyde, toluene, benzene series, TVOC and other harmful substances produced by some furniture materials. The quality of indoor air environment seriously affects people's life and health. It is of certain significance to install plates with antibacterial, antiviral and air ...
