Embodiment 1

[0032] (1) Preparation of mugwort oil microcapsule emulsion: Weigh 0.50g of gelatin and 0.50g of gum arabic into a 250mL three-neck flask, add 50g of distilled water, stir and dissolve in a water bath at 40°C, add 0.50g of mugwort oil and stir Emulsify for 15min. Gradually add 20% acetic acid (HAC) dropwise to the above emulsion to adjust the pH value of the solution to 4.0, reduce the stirring speed to 400r / min, and re-coagulate for 15 minutes; cool the above-mentioned condensed suspension to 0°C with an ice-water bath , then adjust the pH value of the system to 8.0-9.0 with 20% NaOH solution, add dropwise an appropriate amount of 25% glutaraldehyde solution (3-8ml), and then add an appropriate amount of deionized water until the total amount of the emulsion is 100 grams. Continue to ice-bath for 30 minutes under the condition of / min; move to a water bath at 50° C. to continue cross-linking and solidification for 2 hours to obtain a microcapsule emulsion product with a wormw...

Embodiment 2

[0048] (1) Preparation of mugwort oil microcapsule emulsion: Weigh 5g of gelatin and 4.5g of gum arabic into a 250mL three-neck flask, add 60g of distilled water, stir and dissolve in a water bath at 40°C, add 6g of mugwort oil and emulsify for 15min under stirring . Gradually add 20% HAC dropwise to the above emulsion to adjust the pH value of the solution to 4.0, reduce the stirring speed to 600r / min, and re-coagulate for 15 minutes; cool the above-mentioned condensed suspension to 3°C with an ice-water bath, and then use 20% NaOH solution to adjust the pH value of the system to 8.0-9.0, add 5ml (about) 25% glutaraldehyde solution dropwise, and then add an appropriate amount of deionized water until the total amount of the emulsion is 100 grams. Under the condition of stirring speed 600r / min Continue to ice-bath for 30 minutes; move to a water bath at 50° C. to continue cross-linking and solidification for 2 hours to obtain a microcapsule emulsion product with a 6% mugwort o...

Embodiment 3

[0055] (1) Preparation of mugwort oil microcapsule emulsion: Weigh 2g of gelatin and 2g of gum arabic into a 250mL three-neck flask, add 50g of distilled water, stir and dissolve in a water bath at 40°C, add 3g of mugwort oil and emulsify for 15min under stirring. Gradually add 20% HAC dropwise to the above emulsion to adjust the pH value of the solution to 4.0, reduce the stirring speed to 500r / min, and re-coagulate for 15 minutes; cool the above-mentioned coagulated suspension to 0-5°C with an ice-water bath, Then use 20% NaOH solution to adjust the pH value of the system to 8.5, add 3ml of 25% glutaraldehyde solution dropwise, then add an appropriate amount of deionized water until the total amount of the emulsion is 100 grams, and continue the ice bath under the condition of a stirring speed of 500r / min 30 min; move into a water bath at 50° C. to continue cross-linking and curing for 2 hours to obtain a microcapsule emulsion product with a content of 3% mugwort leaf oil.

Abstract

The invention discloses a blumea oil microcapsule antibacterial mask and a preparation method thereof. The mask is formed by sequentially superposing and stitching a super amphiphobic blocking cotton fabric layer, a blumea oil microcapsule antibacterial fabric, a super amphiphobic blocking cotton fabric layer and a contact protective layer cotton fabric from outside to inside. The antibacterial mask is high in efficiency, broad-spectrum, safe, washable antibacterial and antiviral mask having a prevention and treatment effect. The mask has an excellent health-care effect on human skin. At the same time, the prepared fabrics have shrink-resistance and non-ironing effect without the release of formaldehyde or super low formaldehyde, so the mask is an environmentally-friendly multifunctional textile product.

Description

technical field [0001] The invention relates to an antibacterial mask with mugwort leaf oil microcapsules, in particular to an antibacterial mask with mugwort leaf oil microcapsules in the field of health protection and a preparation method thereof. Background technique [0002] Antibacterial masks are generally composed of an outer surface layer, an antibacterial filter layer, an inner surface layer and a scientific shape design. At present, the antibacterial filter materials of antibacterial masks on the market are mainly designed and manufactured based on the relevant knowledge of physics or chemistry. Antibacterial filter materials mainly include activated carbon fiber physical adsorption materials, physical sterilization materials, charged materials, nanocomposite inorganic antibacterial materials, traditional Chinese medicine soaking materials, multifunctional composite antibacterial materials, etc. There are certain problems in practical applications, such as using c...
