Problems solved by technology

However, the distribution of nano-silver in the wall material powder is uneven, and it is easy to agglomerate, so a large amount needs to be added
[0006] The environmentally friendly wall materials that have been disclosed to decompose formaldehyde have low decomposition efficiency for formaldehyde under visible light and are difficult to reuse

Embodiment 1

[0040] 1. Preparation of diatomite

[0041] Take 100g of diatomite, grind it with a ball mill at 200rpm for 1h, separate and remove larger impurity particles with a 200-mesh screen, add 400g of water, stir for 30min, let stand for 10min, suck out the upper layer of turbid solution, and then filter the turbid solution. Put the filter cake into a beaker, add 35% hydrochloric acid solution, stir at 200 rpm for 1 hour at 70°C, and put it into a 150W ultrasonic cleaner. After 2 hours, adjust the pH value of the diatomite suspension to 3, take it out, filter, wash, and vacuum-dry the filter cake at 120°C for 2 hours, then put it in a muffle furnace for calcination at 600°C for 2 hours, and obtain a product with a high specific surface area after expansion. and high-porosity diatomite, the scanning electron microscope (SEM) picture and energy spectrum analysis (EDAX) picture respectively refer to the attached figure 1 (a) and attached figure 2 (a).

[0042] 2. Preparation of tita...

Embodiment 2

[0057] According to the method in Example 1, the original diatom earth was subjected to expansion treatment to obtain diatom concentrate with a high specific surface area.

[0058] Mix 25ml of absolute ethanol with 10ml of butyl titanate, stir at 200rpm for 10 minutes, then add 20g of diatomite, and stir vigorously for 10 minutes to form a slurry. Add 4ml of glacial acetic acid and 10ml of distilled water into 35ml of absolute ethanol, stir at 400rpm for 10min and add hydrochloric acid to adjust the pH value of the solution to 2. The above solution was slowly dropped into the diatomite slurry under stirring, and the dropwise addition was completed in 10 minutes, and stirred at a speed of 400 rpm for 30 minutes and ultrasonically oscillated for 1 hour. Stand still in a water bath at 50°C for 24 hours. After the material forms a gel and cannot flow, it is vacuum-dried at 60°C for 3 hours, and calcined in a muffle furnace at 450°C for 2 hours to obtain titanium-loaded diatomite. ...

Embodiment 3

[0063] According to the method in Example 1, the original diatom earth was subjected to expansion treatment to obtain diatom concentrate with a high specific surface area.

[0064] Mix 35ml of absolute ethanol with 10ml of butyl titanate, stir at 200rpm for 10 minutes, then add 20g of diatomite, and stir vigorously for 10 minutes to form a slurry. Add 4ml of glacial acetic acid and 10ml of distilled water into 25ml of absolute ethanol, stir at a speed of 400rpm for 10min, and add hydrochloric acid to adjust the pH value of the solution to 2. The above solution was slowly dropped into the diatomite slurry under stirring, and the dropwise addition was completed in 10 minutes, stirred at a speed of 400 rpm for 30 minutes and ultrasonically oscillated for 30 minutes. Stand in a water bath at 50°C for 24 hours, and after the material forms a gel and cannot flow, dry it in vacuum at 60°C for 2 hours, and roast it in a muffle furnace at 480°C for 2 hours to obtain titanium-loaded dia...

Abstract

The invention discloses an environment-friendly wall material for interior wall decoration and a preparation method of the wall material. The wall material can continuouly absorb and decompose formaldehyde, has a sterilization function and mainly comprises 1-3 parts of titanium-loaded porous material, 1-3 parts of manganese-loaded porous material, 1-3 parts of silver-loaded porous material, 20-30 parts of talcum powder, 10-20 parts of quartz sand, 40-60 parts of diatomite, 1-3 pats of algin, 1-3 parts of methyl cellulose and 2-5 parts of chitosan gum. The ingredients are uniformly mixed with water in the mass ratio of 1:1 after being mixed, and then the mixture is spread on a wall through a scraper to dry and form naturally. The environment-friendly wall material doesn't release formaldehyde and other gases harmful to human bodies, can adsorb and decompose common indoor harmful gases for a long time and has the effects of killing pathogenic bacteria and adjusting indoor humidity.

Description

technical field [0001] The invention relates to an environment-friendly wall material with air purification function, in particular to an interior wall decoration wall material capable of absorbing and decomposing formaldehyde and having a certain bactericidal function and a preparation method thereof. Background technique [0002] Modern indoor wall materials can not only improve the indoor artistic environment and enable people to enjoy beauty, but also have additional functions such as heat insulation, moisture resistance, fire prevention, sound absorption and sound insulation, which can protect the main structure of the building and prolong its service life. role. At present, commonly used wall materials mainly include wall coatings, wallpapers, decorative panels and wall coverings. These materials have no protective effect on air pollution generated by decoration and other indoor facilities, and are prone to breed bacteria. [0003] At present, the paints, wallpapers, ...
