Scrubbable obsidian photocatalyst spraying solution

Abstract

The invention discloses a scrub-cleanable obsidian photocatalyst spraying liquid. The key points of the technical scheme are that the ingredients are composed of obsidian, acidified attapulgite clay, high-viscosity attapulgite clay, nano-titanium dioxide, white carbon black, nano-silver loaded antibacterial Powder, nano-magnesia, nano-zirconia, nano-alumina, nano-zinc oxide, polyvinyl alcohol, polyethylene glycol, polydimethylsiloxane and water. The ingredients are firstly stirred, dispersed, emulsified, and ground, and then dispersed, homogenized, and ground again, and canned into a scrub-cleaning obsidian photocatalyst spray liquid. Scrubable obsidian photocatalyst spraying liquid is suitable for spraying on the surface of buildings or decorative materials. Under the irradiation of light, it can continuously absorb and degrade pollutants such as formaldehyde, ammonia, and benzene, and has strong sterilization, deodorization, and anti-corrosion properties. Mildew and air purification functions, the film sprayed on the surface of buildings or decorative materials will become saturated after a long period of use, and can be wiped clean with a rag.

Description

technical field [0001] The invention relates to coatings, in particular to a scrubbing obsidian 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 formald...

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, adding some catalysts to building materials or coatings, using the surface activity of the catalyst and the principle of reducing the activation energy of the reaction, decomposes some pollutants that cannot be decomposed at 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
