Diatomite photocatalyst spraying coating liquid capable of being scrubbed

Abstract

The invention discloses diatomite photocatalyst spraying coating liquid capable of being scrubbed. The diatomite photocatalyst spraying coating liquid capable of being scrubbed is characterized in that an ingredient is composed of diatomite, acidified attapulgite clay, high-viscosity attapulgite clay, nano titanium dioxide, white carbon black, nano silver-loaded antibacterial powder, nano magnesium oxide, nano zirconium dioxide, nano aluminum oxide, nano zinc oxide, polyvinyl alcohol, polyethylene glycol, polydimethylsiloxane and water. The ingredient is stirred, dispersed, emulsified and ground and then is dispersed, homogenized and ground again, and is canned to obtain the diatomite photocatalyst spraying coating liquid capable of being scrubbed. The diatomite photocatalyst spraying coating liquid capable of being scrubbed is suitable for being sprayed on the surface of a building or a decorative material; under the irradiation of light, pollutants including formaldehyde, ammonia, benzene and the like can be continuously adsorbed and degraded, and the diatomite photocatalyst spraying coating liquid has extremely strong sterilization, deodorization, mildew prevention and air purification functions; a thin film sprayed on the surface of the building or the decorative material has a saturated state after being used for long time, and can be scrubbed cleanly by utilizing scrubbing cloth.

Description

technical field [0001] The invention relates to coatings, in particular to a scrubbing diatomite photocatalyst spray liquid. Background technique [0002] The current indoor environmental pollution treatment methods: 1. Adopt environmentally friendly building materials. In the process of implementing decoration, from factors such as design, room structure, ventilation conditions, and the superposition effect of harmful gases, environmentally friendly building materials still cannot guarantee the indoor air quality after room decoration. meet the target. 2. Using activated carbon and bamboo charcoal as adsorption materials, the pollutants in the indoor environment are adsorbed on activated carbon and bamboo charcoal to achieve the purpose of removing pollutants. This is only 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 a...

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
