Embodiment 1
[0037] A preparation method for a mask, comprising the steps of:
[0038] (1) Preparation of bacteriostatic microcapsule dispersion: Take 40 parts of bacteriostatic agent thiazole and join 50 parts of dispersant ether, stir at 47°C for 60 minutes at high speed to form a microcapsule core material; 90 parts of bacteriostatic microcapsules Chitosan quaternary ammonium salt, the capsule wall material, was dissolved in 50°C dispersant aqueous solution, and stirred evenly; 25 parts of surfactant sodium dodecylsulfonate was dissolved in 50°C distilled water, and stirred evenly; the above three solutions Mix and stir evenly, and perform shear emulsification at a shear rate of 15,000rmp for 60 minutes; pass the mixed solution after shear emulsification through a 40Mpa high-pressure homogenizer for 30 minutes, and then transfer it to a flask for reaction at a temperature of 50°C After 12 hours, adjust the pH of the solution to 4.5, and after ultrasonic dispersion for 20 minutes, the an...
Embodiment 2
[0048] A preparation method for a mask, comprising the steps of:
[0049] (1) Preparation of bacteriostatic microcapsule dispersion: Take 80 parts of bacteriostatic agent anilide and add it to 100 parts of dispersant, stir at 90°C for 120 minutes at high speed to form a microcapsule core material; 160 parts of bacteriostatic microcapsules Dissolve carboxymethyl chitosan, the capsule wall material, in dispersant at 90°C, and stir evenly; dissolve 50 parts of surfactant sorbitan oleate in distilled water at 90°C, and stir evenly; mix the above three solutions Stir evenly, and perform shear emulsification at a shear rate of 30,000rmp for 120min; pass the mixed solution after shear emulsification through a high-pressure homogenizer of 70Mpa for 60min, and then transfer it to a flask and react at a temperature of 190°C for 24h , adjust the pH of the solution to 7.5, and disperse by ultrasound for 30 minutes to prepare the antibacterial microcapsule dispersion with antibacterial fun...
Embodiment 3
[0058] A preparation method for a mask, comprising the steps of:
[0059] (1) Preparation of bacteriostatic microcapsule dispersion: Take 1 part of bacteriostatic agent isothiazolone and add it to 1 part of dispersant, stir at 5°C for 3 minutes at high speed to form microcapsule core material; mix 2 parts of bacteriostatic microcapsule The capsule wall material carboxymethyl chitosan was dissolved in 10 parts of dispersant, and stirred evenly; 0.2 parts of surfactant polyvinylpyrrolidone was dissolved in distilled water at 10°C, and stirred evenly; the above three solutions were mixed and stirred evenly, It was subjected to shear emulsification at a shear rate of 1000rmp for 2min; the mixed solution after shear emulsification was homogenized by a 10Mpa high-pressure homogenizer for 2min, and then transferred to a flask and reacted at a temperature of 5°C for 1h to adjust the solution The pH is 6.5, and the antibacterial microcapsule dispersion with antibacterial function can b...
