Embodiment 1

[0040] First, the preparation of the filter element is described:

[0041] Evenly roll-coat the UV-responsive adhesive on the filter parts, add 10 g of pulverized potassium iodide powder into 990 g of water and dissolve to obtain a solution with a mass fraction of 1%, and spray 50 ml of the solution on the surface of the filter parts (the size of the filter parts is about the same A circular material of about 5cm), through the ultraviolet response adhesive, potassium iodide is fixed on the filter component (only the raw material is left after the water evaporates), and the filter component with virus and bacteria inactivation is obtained. Since the UV-responsive adhesive can increase the combination of potassium iodide and the filter component, the inactivation component potassium iodide is stably placed in the filter component, which can effectively inactivate viruses and bacteria, and can inactivate viruses and bacteria for a long time last longer. In this solution, the sur...

Embodiment 2

[0044]The preparation of the filter parts constituting the mask main body is the same as in Example 1. Add a total of 10g of potassium iodide and iodine with a mass ratio of 1:1 to 900g of degradable polymer polyglycolic acid to make a solution, and spray 50ml of the prepared solution evenly on the surface of the filter component. Through drying, the potassium iodide and iodine are fixed on the filter component by the degradable polymer polyglycolic acid to obtain the filter component with virus and bacteria inactivation function. Since the degradable polymer polyglycolic acid can increase the combination of potassium iodide and iodine with the filter components, the virus and bacteria inactivation components potassium iodide and iodine are stably placed in the filter components, which can effectively inactivate viruses and bacteria , and can inactivate viruses and bacteria for a longer period of time. In this solution, the surface of the filtering component is coated on one ...

Embodiment 3

[0047] The preparation of the filter parts constituting the mask main body is the same as in Example 1. Take 50ml of iodine solution (1% by mass of iodine) and heat it to 120-150°C to sublimate it, and place one side of the mask on top of the iodine solution. The iodine solution will be directly adsorbed on the filter component placed thereon, thereby obtaining the filter component with the function of inactivating germs. Due to the stable combination of iodine in the iodine solution and the filter component, the inactivation component iodine is stably placed in the filter component, which can effectively inactivate viruses and bacteria, and can inactivate viruses and bacteria for a long time last longer. In this solution, the surface of the filtering component is coated on one side. In an alternative embodiment, double-sided coating can also be applied on the surface of the filtering component.

[0048] Then, use the filter member with germ inactivating components to form t...

Abstract

The invention discloses a mask containing bacteria inactivation components and a preparation method thereof. The mask comprises a filtering component, the filtering component contains a germ inactivation component, and the germ inactivation component comprises halide; the pathogen inactivation component is connected to the filtering component through one or more of the following methods: (1) after the filtering component is soaked in a solution containing the pathogen inactivation component, chemical bonding is realized through irradiation of active energy rays or heating; (2) combining the pathogen inactivating component and the filtering component together through an ultraviolet response adhesive; (3) coating the surface of the filtering component with a mixture of the germ inactivation component and the degradable high polymer material; and (4) heating and sublimating the pathogen inactivating component, so that the pathogen inactivating component is adsorbed on the filtering component. The pathogen inactivation component in the mask is connected to the filtering component in a specific mode, the safety when the mask is worn can be improved, and secondary pollution is avoided.

Description

technical field [0001] The invention specifically relates to a mask containing germ inactivating components and a preparation method thereof. Background technique [0002] This year, regarding the new type of pneumonia caused by the new coronavirus, there have been reports of SARS, Middle East Respiratory Syndrome, bird flu and other diseases transmitted through the respiratory tract. Due to the development of transportation and the mutation of the virus, the virus infection is spreading around the world. In the face of such an infection outbreak crisis, it is necessary to formulate urgent countermeasures. In response to such a situation, the development of antiviral vaccines is also being rapidly advanced, but vaccines can only prevent infection by specific viruses because of their specificity. Moreover, it takes a very long time to prepare a vaccine against a new strain of virus. [0003] In order to prevent the infection of these viruses, it is recommended to wear a mas...
