The existing mask mainly aims at filtration, but the mask does not have the sterilization or disinfection function, microorganisms attached to the mask or microorganisms in the mask can continuously survive for several hours, and the possibility of cross infection is greatly enhanced, so that the mask with the sterilization function needs to be researched.
Disclosure of Invention
Aiming at the problems, the invention provides the mask with the sterilization function, and the mask obtained by adopting the mask is degradable and has strong sterilization and bacteriostasis effects.
The mask with the sterilization function is characterized in that the filter layer of the mask is obtained by the following steps:
(1) mixing ginger stalk fiber and aramid fiber, and carbonizing to produce fiber material with carbon as main fiber;
(2) immersing the fiber material into a mixed solution of silver nitrate and polyhexamethylene biguanide hydrochloride, then adding sodium triacetoxyborohydride, and stirring for reaction;
(3) after the reaction is finished, the product is washed by deionized water and then dispersed in water to be made into a sheet-shaped base material, namely a filter layer of the mask.
The ginger stalk fiber is obtained by extracting ginger stalks.
The mass ratio of the ginger stalk fibers to the aramid fibers is 1: 1-5.
The carbonization temperature in the step (1) is 200-220 ℃, and the carbonization time is 2 h.
In the mixed solution in the step (2), the mass ratio of silver nitrate to polyhexamethylene biguanide hydrochloride is 1: 1-2.
In the step (2), the mass ratio of the fiber material to the mixed solution is 1: 1-5.
In the step (2), the mass of the sodium triacetoxyborohydride is 1-10 times of that of the silver nitrate.
In the step (2), the reaction temperature is 20-30 ℃, and the reaction time is 10-12 h.
In the step (3), the quantitative of the paper making is 20-30g/m2Of (2) a sheet-based material.
After the filter layer of the mask is obtained, the mask can be processed into the mask according to the technical means known in the field.
According to the invention, the ginger stalk fibers obtained by extracting ginger stalks contain curcumin, so that the ginger stalk fibers have the functions of sterilization and bacteriostasis, have high aramid fiber strength and can be used as a base material. The guanidine salt in the step (2) has the functions of sterilization and bacteriostasis, and silver generated after the reaction of the silver nitrate and the sodium triacetoxyborohydride also has the functions of sterilization and bacteriostasis. Because the fiber has certain adsorbability, the generated tiny silver particles can be attached to the surface of the fiber, and further, sufficient sterilization and bacteriostasis are ensured.
Compared with the prior art, the invention has the following beneficial effects:
(1) in the invention, the curcumin, the guanidine salt and the silver act together, and the three synergistically improve the sterilization and bacteriostasis effects of the mask.
(2) The ginger stalk fiber and the aramid fiber are used in a matching way, so that the degradability of the final product is improved, and the strength of the product is ensured.
(3) Because the fiber has adsorbability, more generated silver particles can be adsorbed on the surface of the fiber, the time for sterilization and bacteriostasis is prolonged, and the effects of sterilization and bacteriostasis are enhanced.
