Problems solved by technology

Although this method can effectively reduce the concentration of polluting gases in the environment, ultraviolet light must be involved, otherwise the removal rate of harmful substances is not high, and its application in indoor air purification is greatly limited.

preparation example Construction

[0018] The present invention also provides a kind of preparation method of above-mentioned diatom ooze, it comprises the following steps:

[0019] Fully soak the diatomite with acid to remove the water-soluble impurities therein, filter the acidified diatomite with deionized water to remove impurities and dry it to obtain purified diatomite; then mix the purified diatomite with mica, The cellulose, talcum powder, titanium platinum, and shadowless glue are thoroughly mixed, and finally water is added and stirred for two to three hours to obtain the diatom mud.

[0020] Furthermore, the above steps specifically also include: fully soaking the diatomite with sulfuric acid, nitric acid or hydrochloric acid for 5-10 hours to remove water-soluble impurities therein, the mass of the diatomite and sulfuric acid, nitric acid or hydrochloric acid The ratio is between 1:10-1:50.

Embodiment 1

[0023] 2 kilograms of diatomite, 0.25 grams of mica, 0.12 grams of cellulose, 1.75 kilograms of talcum powder, 0.15 grams of titanium platinum and 0.25 grams of shadowless glue, and the balance is water, and diatoms are prepared according to the above-mentioned preparation method The mud was then applied to the interior wall of a 15-square-meter house, and the house was closed for 45 days to test indoor harmful substances. The concentration of formaldehyde was 0.07 mg per cubic meter.

Embodiment 2

[0025] 300 kilograms of diatomite, 50 grams of mica, 18 grams of cellulose, 120 kilograms of talcum powder, 20 grams of titanium platinum and 30 grams of shadowless glue, the balance is water, and diatoms are prepared according to the above-mentioned preparation method The mud was then applied to the interior wall of a 400-square-meter house, and the house was closed for 50 days to test indoor harmful substances. The concentration of formaldehyde was 0.05 mg per cubic meter. As shown in Table 1 about the purification status,

Abstract

The invention discloses diatom mud and a preparation method thereof. The diatom mud comprises the following raw materials by weight parts: 1,500-3,000 parts of diatomite, 0.1-0.5 part of mica, 0.1-0.2 part of cellulose, 1,000-2,000 parts of talcum powder, 0.1-0.2 part of titanium platinum, 0.1-0.5 part of shadowless glue and the balance of water. The porous diatom mud is prepared from the materials such as the diatomite, the mica and the like; indoor harmful substances, especially chemical substances such as formaldehyde and the like are adsorbed through the porous diatom mud; the degradation rate and the removal rate of the indoor harmful substances are increased; the removal rate of indoor formaldehyde by the diatom mud as a coating material is more than 80%; moreover, the situations of cracking and the like of the diatom mud applied to a wall can not be caused, and then the interior decoration is more attractive.

Description

technical field [0001] The invention relates to interior decoration materials, in particular to a diatom mud and a preparation method thereof. Background technique [0002] In modern architectural design, the effective use of energy is increasingly considered, and the ventilation with the outside world is less and less. In this case, the indoor environment, especially the environment that has just been renovated, releases from various decoration materials. The concentration of pollutants is very high, and the pollutants cannot be discharged outdoors under the condition of insufficient ventilation. A large number of pollutants stay indoors for a long time, making the concentration of indoor pollutants very high. In severe cases, the concentration of indoor pollutants can exceed that of outdoors. Dozens of times as much. In order to effectively solve the problem of indoor environmental pollution, nano-silica is added to traditional building materials to increase the function ...
