Example Embodiment

[0039] Example 1:

[0040] 1. Preparation of diatomaceous earth

[0041] Take 100 g of diatomaceous earth and grind it with a ball mill at 200 rpm for 1 hour. After separating and removing larger impurity particles with a 200 mesh screen, add 400 g of water, stir for 30 min, and let stand for 10 min. The upper turbid liquid is sucked out, and then the turbid liquid is filtered. Put the filter cake into a beaker, add a 35% concentration of hydrochloric acid solution, stir at 70°C at 200 rpm for 1 hour, and put it into a 150W ultrasonic cleaner. After 2h, adjust the pH value of the diatomaceous earth suspension to 3, take it out, filter, wash, and dry the filter cake in vacuum at 120℃ for 2h, then put it in a muffle furnace and calcinate at 600℃ for 2h, that is, it has a high specific surface area after expansion. For the scanning electron microscope (SEM) image and energy spectrum analysis (EDAX) image of diatomite with high porosity, please refer to the attached figure 1 (a) and a...

Example Embodiment

[0056] Example 2:

[0057] According to the method in Example 1, the original diatomaceous earth was expanded to obtain a diatomaceous earth with a high specific surface area.

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

[0062] Example 3:

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

[0064] Mix 35 ml of absolute ethanol with 10 ml of butyl titanate, stir at 200 rpm for 10 min, add 20 g of diatomaceous earth, and stir vigorously for 10 min to form a slurry. Add 4ml of glacial acetic acid and 10ml of distilled water to 25ml of absolute ethanol, stir at 400rpm for 10min, add hydrochloric acid to adjust the pH of the solution to 2. Under stirring, the above solution was slowly dropped into the diatomaceous earth slurry, and the addition was completed in 10 minutes, and stirred at 400 rpm for 30 minutes and ultrasonically vibrated for 30 minutes. Let it stand in a water bath at 50°C for 24h. After the material forms a gel and cannot flow, it is vacuum dried at 60°C for 2h, and calcined in a muffle furnace at 480°C for 2h to obtain titanium-loaded diatomite.

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, ...
