Abstract

The invention relates to an antibacterial waterproof moisture-permeable nano fiber membrane and a preparation method thereof. The nano fiber membrane comprises the following components: 80-90% of polyurethane, 8-15% of tetrabutylammonium bromide and 2-5% of a zirconium phosphate silver-loaded antibacterial agent, and the average particle size of the zirconium phosphate silver-loaded antibacterialagent does not exceed 0.3 micrometer. The preparation method comprises the following steps: (1) preparing a polyurethane / tetrabutylammonium bromide / N,N-dimethylformamide solution of which the concentration ranges from 5% to 10%; (2) uniformly dispersing zirconium phosphate silver-loaded antibacterial agent particles into a solution prepared in step (1) to obtain a spinning solution; and (3) preparing a thick and thin double-scale-structured nano fiber membrane under high-pressure static action force.

Description

technical field [0001] The invention relates to an antibacterial waterproof and moisture-permeable nanofiber membrane and a preparation method thereof, belonging to the technical field of protective materials. technical background [0002] Antibacterial property is an important indicator of medical protective clothing. However, when using film-coated materials to achieve the best protective antibacterial effect, it is impossible to avoid the disadvantages of stuffiness for the wearer; and materials with good air permeability and moisture permeability are usually not good at blocking blood. , alcohol and other liquids, so it is necessary to find a balance between the two in order to achieve protection and comfort. As the core material of medical protective clothing, waterproof and moisture-permeable microporous membrane not only has excellent protective performance, but also has good moisture permeability. At present, the main technologies for manufacturing waterproof and mo...
