Embodiment 1

[0025] Prepare the photocatalytic air purification decorative board according to the following steps:

[0026] 1) In parts by weight, mix 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-silica. Mix thoroughly and stir evenly. Add 0.5 part of silane coupling agent and stir for 60 minutes. Prepare the mixture powder A;

[0027] 2) Then 15 parts by weight of silica sol, 0.8 parts of carboxymethyl cellulose, 0.3 parts of silane coupling agent, 0.06 parts of organic silicon 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, mixed and stirred at 90° C. for 120 minutes; 6 parts of anatase crystal type nano titanium dioxide powder was added under stirring to prepare adhesive B; the silica sol contained 30% silica.

[0028] 3) Mix the mixture powder A and the adhesive B at a weight ratio...

Abstract

The invention discloses a preparation method of a photocatalytic air purification decorative plate. The preparation method comprises the following steps: 1) fully and uniformly mixing and stirring 2-10 parts by weight of shell powder, 0.1-5 parts by weight of activated carbon powder and 2-8 parts by weight of a light guide agent, adding 0.1-1 part by weight of a silane coupling agent, and stirringfor 30-60 minutes to obtain mixed powder A; 2) mixing and stirring 10-20 parts by weight of silica sol, 0.5-2 parts by weight of water-soluble cellulose, 0.1-0.5 part by weight of a silane coupling agent, 0.01-1 part by weight of an organosilicon surfactant, 0.1-2 parts by weight of aluminum powder and 0.1-5 parts by weight of hydrogen peroxide at 40-100 DEG C for 60-120 minutes; adding 1-6 partsof nano titanium dioxide powder under the stirring action to prepare an adhesive B. The photocatalytic air purification decorative plate has the advantages of porous adsorption effect, high photocatalytic efficiency and strong adhesion between nano titanium dioxide and a 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] The indoor air environment of the building is affected by the furniture decoration or the space structure, which makes the indoor local environment air flow poorly, the air is easily polluted, and the 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 The quality of indoor air environment seriously affects people’s life and health, such as gas, hydrogen sulfide, sulfide, nitrogen oxide and other odorous gas substances, as well as formaldehyde, toluene, benzene series, TVOC and other harmful substances produced by some furniture materials. It is meaningful to install panels with antibacterial, anti-virus, and air purification functions in the decora...
