[0029] The preparation method of the anti-smog mask of the present invention includes the production of the cover body and the production of the isolation filter. The manufacture of the isolation filter is the key technology of the method of the present invention. The isolation filter is prepared according to the following steps:
[0030] a. Configure TiO2 sol: take absolute ethanol, tetrabutyl titanate, and water. The volume ratio of the above three substances is absolute ethanol: tetrabutyl titanate: water = 30:1:3. Mix two-thirds of the amount with tetrabutyl titanate and stir uniformly, mix the remaining absolute ethanol with water and drop it into the mixture of absolute ethanol and tetrabutyl titanate, add acid to adjust the pH of the above mixture to 3. Continue stirring for 2 hours to prepare TiO2 sol.
[0031] b. Configure the chitosan solution glue: configure the chitosan solution glue according to the ratio of 1-5g chitosan and 5-25mg iodized salt in 80ml acid solution a...
Example Embodiment
[0040] Example 1: Take anhydrous ethanol, tetrabutyl titanate, and water in a volume ratio of 30:1:3, mix two-thirds of the total amount of anhydrous ethanol with tetrabutyl titanate and stir evenly. After mixing the water ethanol and water, drip into the mixture of absolute ethanol and tetrabutyl titanate, add acid solution to adjust the pH of the above mixture to 3, and continue to stir for 2 hours to prepare TiO2 sol; according to 80ml acid solution and 20ml water , 1g chitosan and 5mg potassium iodide in the ratio of chitosan solution gel, mix the proportion of potassium iodide and water into uniform iodine brine, mix and stir the proportion of chitosan, acid solution and iodine brine, When the chitosan is completely dissolved, a chitosan solution gel is prepared. The acid solution is acetic acid with a mass concentration of 1%; take the prepared TiO2 sol and chitosan solution gel, and mix the TiO2 sol according to a volume ratio of 1:9 Add to the chitosan solution glue, ma...
Example Embodiment
[0041] Example 2: Take anhydrous ethanol, tetrabutyl titanate, and water in a volume ratio of 30:1:3, mix two-thirds of the total amount of anhydrous ethanol with tetrabutyl titanate and stir evenly. After mixing the water ethanol and water, drip into the mixture of absolute ethanol and tetrabutyl titanate, add acid solution to adjust the pH of the above mixture to 3, and continue to stir for 2 hours to prepare TiO2 sol; according to 80ml acid solution and 20ml water Add 3g chitosan and 10mg ammonium iodide to prepare the chitosan solution gel, mix the proportioned amount of ammonium iodide and water into a uniform iodized brine, and mix the proportioned amount of chitosan, acid solution and iodized salt Mix the water and stir until the chitosan is completely dissolved, and then prepare a chitosan solution gel. The acid solution is 2% mass concentration hydrochloric acid; take the prepared TiO2 sol and the chitosan solution gel, according to a volume ratio of 1: 10 Add TiO2 sol...
