Problems solved by technology

[0002] In recent years, the smog weather has become more and more serious, especially in winter, pm2.5 has seriously exceeded the standard, and the formaldehyde content in the renovated places often exceeds the standard. The fog has brought a great threat to people's health. The current ordinary masks The adsorbent is basically activated carbon, but the adsorption and filtration effect of activated carbon on particulate pollutants is limited, and various organic waste gas pollutants in the atmosphere are gradually increasing. Activated carbon adsorbents cannot decompose and remove these pollutants, even if they are adsorbed on masks. have an impact on human health

Embodiment 1

[0022] Prepare samples of choline chloride and hexadecyltrimethylammonium bromide with a molar ratio of 1:3.

[0023] 0.02mol choline chloride, 0.06mol cetyltrimethylammonium bromide, 5ml silica sol, 0.06mol sodium metaaluminate, 2mol / L 12ml sodium hydroxide solution, 24ml 98% sulfuric acid, 0.01mol dioxide Silicon powder, 0.001mol praseodymium nitrate, 0.001mol cerium nitrate, 300ml deionized water.

[0024] Step 1. First, NaAlO2, NaOH, and deionized water are ultrasonically oscillated for 3 hours in a neon atmosphere;

[0025] Step 2. Dissolve 0.06mol NaAlO2, 2mol / L 12ml NaOH solution in 90°C oil bath under magnetic stirring and completely dissolve it in 200ml deionized water to form a transparent sodium aluminate solution;

[0026] Step 3. Ultrasonically shake the silica sol and sulfuric acid for 3 hours in a neon atmosphere, then drop 5ml of silica sol into the transparent sodium aluminate liquid at a rate of 40 drops per minute, stir magnetically, heat in an oil bath at ...

Embodiment 2

[0034] Example 2 Preparation of two organic templates, choline chloride and cetyltrimethylammonium bromide, with a molar ratio of 1:1, that is, 0.02mol choline chloride and 0.02mol cetyltrimethylammonium bromide Ammonium, all the other raw materials are identical with embodiment 1, and preparation method industry is identical with embodiment 1.

Embodiment 3

[0035] Example 3 Preparation of choline chloride and cetyltrimethylammonium bromide, the molar ratio of these two organic templates is 1:2, that is, 0.02mol choline chloride and 0.04mol cetyltrimethylammonium bromide Ammonium, all the other raw materials are identical with embodiment 1, and preparation method industry is identical with embodiment 1.

Description

technical field [0001] The invention relates to an air purification mask, which belongs to the field of daily life. Background technique [0002] In recent years, the smog weather has become more and more serious, especially in winter, pm2.5 has seriously exceeded the standard, and the formaldehyde content in the renovated places often exceeds the standard. The fog has brought a great threat to people's health. The current ordinary masks The adsorbent is basically activated carbon, but the adsorption and filtration effect of activated carbon on particulate pollutants is limited, and various organic waste gas pollutants in the atmosphere are gradually increasing. Activated carbon adsorbents cannot decompose and remove these pollutants, even if they are adsorbed on masks. have an impact on human health. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides an air-purifying face mask, which has good formald...
