Coal ash photocatalyst spraying liquid capable of being scrubbed

Abstract

The invention discloses a coal ash photocatalyst spraying liquid capable of being scrubbed. Main points of the technical scheme is that ingredients of the spraying liquid comprise coal ash, acidified attapulgite clay, high-viscosity attapulgite clay, nanometer titanium dioxide, white carbon black, nanometer silver loading antibacterial powder, nanometer magnesium oxide, nanometer zirconium dioxide, nanometer alumina, nanometer zinc oxide, polyvinyl alcohol, polyethylene glycol, polydimethylsiloxane and water. The ingredients are stirred, dispersed, emulsified and ground and are re-dispersed, homogenized and ground, and the coal ash photocatalyst spraying liquid is canned. The spraying liquid can be sprayed to the surface of a building or a decorative material. Under the light, pollutants, such as formaldehyde, ammonia and benzene, can be continuously adsorbed and degraded. The spraying liquid has great function of sterilization, deodorization, mold prevention and air purification, can be sprayed to a film located on the surface of a building or a decorative material, and presents a saturated state after use for a long time. The spraying liquid can be cleaned with rag.

Description

technical field [0001] The invention relates to coatings, in particular to a scrub-washable fly ash photocatalyst spraying liquid. Background technique [0002] The current indoor environmental pollution treatment methods: 1. Use environmentally friendly building materials. In the process of implementing decoration, considering factors such as design, room structure, ventilation conditions, and the superimposed effect of harmful gases, environmentally friendly building materials still cannot guarantee indoor air quality after room decoration. Up to standard. 2. Use activated carbon and bamboo charcoal as adsorption materials to adsorb pollutants in the indoor environment on activated carbon and bamboo charcoal to achieve the purpose of removing pollutants. This is just adsorption rather than absorption, and it cannot completely decompose pollutants. It can only be temporarily When the room temperature rises and the adsorption is saturated, volatile organic gases such as for...

3. Hope to use green plants such as Chlorophytum and Aloe Vera to absorb. In fact, the adsorption capacity of plants is quite limited. If the formaldehyde in the room exceeds the standard, thousands of pots of plants and continuous light are needed to achieve a certain effect.

5. Using the principle of photocatalysis, add some catalysts to the decorative materials or coatings, and use the surface activity of the catalysts and the principle of reducing the activation energy of the reaction to decompose some pollutants that cannot be decomposed under normal temperature to achieve the purpose of purification. However, pure photocatalyst powder is not practical

[0005] The deficiencies of the above-mentioned patents are: 1. The diatomite, quartz sand, bentonite and other raw materials used in the ecological wall materials that can decompose formaldehyde and can be scrubbed have not undergone necessary modification treatment, so it is difficult to improve the adsorption performance of these raw materials. Can't "decompose and absorb formaldehyde, improve indoor humidity, absorb indoor moisture" very well

2. The construction p
