Embodiment 1

[0043] A method for preparing a metal ion coordination capture adsorption enhanced mask main body material, comprising the following steps:

[0044] S1. After adding 72.5% glycerol in the first beaker, add 25% sodium polyacrylate and 2.5% aluminum glycerol, and stir for 10 minutes to completely disperse all the ingredients to obtain component A;

[0045] S2. After putting 95% distilled water into the second beaker, add 2.5% tartaric acid and 2.5% disodium edetate, stir for 20 minutes, and completely disperse all the ingredients to obtain group B Minute;

[0046] S3. Mix component A and component B according to the ratio of 1:5, vacuumize and stir for 20 minutes to completely disperse all components to obtain a hydrogel;

[0047] S4. Use the hydrogel obtained in step S3 to modify the non-woven fabric of the core layer by padding, and then dry at 80° C. for 6 hours to obtain the main material of the mask with enhanced metal ion coordination capture and adsorption.

Embodiment 2-6 and comparative example 1-2

[0050] The difference between Examples 2-6 and Comparative Examples 1-2 and Example 1 is that in the process of preparing the hydrogel, the mass fraction ratio of sodium polyacrylate, aluminum glycolate and glycerol in the A component is changed, and the mass fraction ratio of the B component is changed. The mass fraction ratio of middle water, tartaric acid, disodium edetate, other steps are basically the same as those in Example 1, and are not repeated here; in Example 2 to Example 6, sodium polyacrylate, aluminum glycolate, glycerol , water, tartaric acid, and disodium edetate are shown in the following table:

Abstract

The invention discloses a preparation method of a metal ion coordination capture adsorption enhanced mask main body material. The preparation method comprises the following steps: stirring and mixing glycerol, sodium polyacrylate and dihydroxyaluminum aminoacetate to obtain a component A; stirring and mixing distilled water, tartaric acid and disodium ethylene diamine tetraacetate to obtain a component B; fully mixing the component A and the component B to obtain hydrogel; and finally, modifying a non-woven fabric by using the hydrogel, and drying to obtain the metal ion coordination capture adsorption enhanced mask main body material. Through the mode, coordination bonds of aluminum ions and carboxyl in the hydrogel can form a capture and adsorption effect, so that the blocking and protecting capability of a common mask material on pollutants is further improved; moreover, along with the prolonging of the service time of the mask, the water is continuously accumulated, so that the hydrogel is further promoted to release more aluminum ions and carboxyl groups, the attenuation degree of the filtering efficiency of the mask is obviously slowed down, and relatively high filtering efficiency is still kept, thereby prolonging the service life of a common disposable mask.

Description

technical field [0001] The invention relates to the technical field of sanitation protection, in particular to a metal ion coordination, capture and adsorption enhanced mask body material, a preparation method thereof and a mask. Background technique [0002] As the problem of air pollution becomes more and more serious, the protection consciousness of the whole people has been significantly improved. As the most convenient, economical and effective protective equipment, the demand for masks is increasing sharply every year. Now it has become a necessity for everyone's daily travel. [0003] In the prior art, the protection process of masks mainly utilizes the physical adsorption of electrostatic electret to block pollutants such as viruses and particulate matter in the air to protect human health; however, electrostatic electret masks are easy to dissipate when exposed to water. , At the same time, the process of human breathing will inevitably produce a lot of water, resul...
