Abstract

The invention belongs to the technical field of medical and health products, and particularly relates to reusable mask fabric and a preparation method thereof. The preparation method includes the steps: adding polyvinylidene fluoride resin powder, polyurethane powder, nano powder and liquid polyacrylonitrile into a graphene oxide aqueous solution containing 1-butyl-3-methylimidazolium bis (trifluoromethanesulfonyl) imide; uniformly performing oscillating by ultrasonic waves to obtain a paste material, and then pewreforming pushing and pressing, calendering, foaming by microwaves, stretching, sintering and molding, and reducing the processed paste material to obtain the product. A corresponding mask product can be obtained by processing the mask fabric, is not limited by an electret technology any more, realizes interception of bacteria, viruses, dust and the like by controlling the pore diameter of micropores of the film, and can be reused infinitely theoretically. An adhesive is not used for being compounded with other materials, so that the permeation resistance of gas is not increased, and better air permeability is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical and sanitary products. More specifically, it relates to a reusable mask fabric and a preparation method thereof. Background technique [0002] With the development of economic activities, environmental pollution is becoming more and more serious, smog pollution occurs frequently, people's awareness of hygiene is gradually improving, and the use of masks is gradually increasing. Commonly used masks include cotton masks, medical masks, etc. The traditional cotton gauze mask is made of superimposed layers of mesh gauze, which is heavy, uses a lot of yarn, and has high cost. It has limited ability to prevent the spread of bacteria such as droplets, and there will be uneven density after washing. There will also be holes, resulting in uneven filtration and losing the basic function of the mask. [0003] Disposable masks are a very common medical mask, usually composed of inner, middle and outer laye...
