Problems solved by technology

However, if a sterilizing mask made of volatile bactericidal and antiviral agents such as ethanol and hypochloride is used, this mask has a certain timeliness, and its antibacterial effect will be greatly reduced as the bactericidal and antiviral agent volatilizes.
If a sterilizing mask is made of a sterilizing mask made of organic synthetic bactericidal and antiviral agents such as quaternary ammonium salts, urea, guanidine, and organometallics, such bactericidal and antiviral agents are in direct contact with human skin, and it is easy to Cause allergic and other adverse reactions to people with sensitive constitutions, and its biological safety is open to question

Embodiment 1

[0036] Extraction of active ingredients in turmeric: get 2kg turmeric to wash, pulverize, add acid and hydrolyze, centrifuge to separate solid hydrolyzate; use ethyl acetate as extractant, carry out reflux extraction, the volume-to-mass ratio of extractant to solid hydrolyzate during extraction 4:1, extract for 3 hours; then adjust the pH to 8.5 with ammonia water in the purified solution; take the supernatant, use ethyl acetate as the extractant, and carry out reflux extraction to obtain the turmeric root extract; concentrate the turmeric root extract to the original After 1 / 3 of the volume, carry out 200 mesh silica gel column chromatography, then use No. 6 gasoline, chloroform volume ratio as solvent elution 4h, utilize ultraviolet detector, at 230nm, collect curcumarrhizol respectively according to the peak , yellow root diol crude crystals; curcumarrhizol, yellow root glycol crude crystals are dissolved with ethanol solution respectively, filter, after the filtrate is conc...

Embodiment 2

[0040] The extraction of active ingredient in turmeric: with embodiment 1.

[0041] The configuration of the composite finishing solution: use sodium dodecylbenzenesulfonate and Tween-80 with a mass ratio of 2:1 as the emulsifier, and emulsify xanthoradiol into an emulsion with a concentration of 10%wt. Then it is further configured into an antibacterial finishing solution, including the following components: the concentration of turmeric root extract (10wt% active ingredient) is 30g / L, the concentration of mugwort extract (commercially available essential oil) is 5g / L, and the cross-linking agent (a composition formed by mixing citric acid and DL-2,3-dihydroxybenzoic acid at a molar ratio of 2:1) the concentration is 35g / L, the concentration of sodium hypophosphite is 3g / L, and the concentration of JFC is 1g / L L, the solvent is deionized water.

[0042] Antibacterial finishing: at room temperature, immerse the cotton fabric in the composite finishing solution for 15 minutes,...

Abstract

The invention discloses a plant antibacterial agent based facing material and a preparation method thereof and belong to the field of medical protective articles. The preparation method comprises thefollowing steps: mixing a turmeric root extracting solution, a Chinese mugwort extracting solution, a cross-linking agent and JFC into composite finishing liquor according to a predetermined proportion; under a room-temperature condition, soaking cotton fabric into the composite finishing liquor for 10-30 minutes, performing secondary leaching and secondary rolling, and pre-drying for 2-5 minutesat a temperature of 50-70 DEG C, wherein a mangle expression is 75%-85%; baking for 5-10 minutes at a temperature of 125-155 DEG C, cleaning cotton fabric with deionized water, removing flooding, andcarrying out natural drying. The turmeric root extracting solution is taken as a natural antibacterial agent, and is matched with Chinese mugwort essential oil to reduce thrill, on skin, of the antibacterial agent, so that the biological safety is higher; compound polybasic carboxylic acid is taken as the cross-linking agent, so that influence on whiteness of the cotton fabric is avoided; and a padding process is optimized, so that a color fixation rate is increased.

Description

technical field [0001] The invention belongs to the field of medical protective products, in particular to a plant-based antibacterial agent-based decorative material and a preparation method thereof. Background technique [0002] When respiratory infectious diseases are prevalent, or when working in a polluted environment such as dust, wearing a mask has a very good effect, and it can filter out bacteria or pollutants by filtering. However, as people pay more and more attention to personal protection against bacteria, viruses, pollutants, etc., and since masks are mostly made of cloth or paper, especially ordinary medical surgical masks, during long-term wearing, the water vapor exhaled by the human body Or the sweat discharged will adhere to the surface of the mask, providing suitable growth conditions for filtering bacteria or pollutants on the surface of the mask. Therefore, the continuous time of such masks should not be too long, and it is not recommended to use them ...
