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 process of decomposable formaldehyde and scrubable ecological wall materials includes the following steps: "Mix the decomposable formaldehyde and scrubable ecological wall materials with water at a weight ratio of 1:0.8, stir into a paste; then apply on The base surface that needs to be applied can be used”, “the water-retaining agent can absorb water equivalent to a hundred times its own weight”, and the formaldehyde-decomposing, scrub-able ecological wall material is mixed with water at a weight ratio of 1:0.8, and the water in the ingredients It will be completely absorbed by the water-retaining agent. This simple production process is difficult to mix the raw materials of the decomposable formaldehyde and scrubable ecological wall materials evenly, and it cannot solve the problem of agglomeration of materials such as titanium dioxide and negative ion powder. function of material
3. Just "stir it into a paste, and then apply it on the base surface to be smeared", it is difficult to form a firm film on the "base surface", and it is easy to fall off from the "smeared base surface". The effect of purifying indoor air

Embodiment Construction
[0048] Below in conjunction with embodiment the present invention will be further described:
[0049] 1. The ingredients of the scrubable medical stone photocatalyst spraying liquid are composed of the following components by weight percentage: 8% medical stone, 5% acidified attapulgite clay, 3% high-viscosity attapulgite clay, and 2% nano-titanium dioxide , white carbon black 2%, nanometer silver loaded antibacterial powder 1.5%, nanometer magnesia 2%, nanometer zirconia 0.5%, nanometer aluminum oxide 1%, nanometer zinc oxide 0.5%, polyvinyl alcohol 2%, polyethylene glycol 0.3%, Dimethicone 0.2%, and Deionized Water 72%.
[0050] 2. The production method of the scrubable medical stone photocatalyst spray liquid: (1) Input the ingredients of the scrubable medical stone photocatalyst spray liquid into the running high-speed disperser for strong stirring, dispersion and emulsification, and then input into the three-roll mill for grinding It is the semi-finished product of the s...

Abstract
The invention discloses cleanable medical stone photocatalyst spray coating liquid, which is mainly characterized by being prepared from ingredients of medical stone, acidized attapulgite clay, high-viscosity attapulgite clay, nanometer titanium dioxide, white carbon black, nanometer sliver-carried antibacterial powder, nanometer magnesium oxide, nanometer zirconium dioxide, nanometer aluminum oxide, nanometer zinc oxide, polyvinyl alcohol, polyethylene glycol, polydimethylsiloxane and water. Firstly, the ingredients are stirred, dispersed, emulsified and ground, and are then dispersed again, homogenized and ground; canning is performed to obtain the cleanable medical stone photocatalyst spray coating liquid. The cleanable medical stone photocatalyst spray coating liquid is suitable for being sprayed and spread onto the surface of a building or a decoration material; under the light irradiation, contaminants such as formaldehyde, ammonia and benzene can be continuously adsorbed and degraded; strong sterilization, deodorization, mildew-proof and air purification functions can be realized; a film sprayed and spread on the surface of the building or the decoration material can show a saturation state after the long-time use, and can be cleanly wiped by a rag.
Description
technical field [0001] The invention relates to coatings, in particular to a medical stone photocatalyst spraying liquid which can be scrubbed. 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 gase...
