Preparation method of built-in nasal cavity polyurethane filtering material with antibacterial function

Abstract

The invention discloses a preparation method of a built-in nasal cavity polyurethane filtering material with antibacterial function, wherein the prepared polyurethane has energy storage and antibacterial functions by using polyethylene glycol and an antibacterial agent. According to the invention, the polyurethane filtering material with phase change and antibacterial functions is prepared by using an electrostatic spinning method, and through rolling and cutting, the filtering material has a round table shape capable of being plugged into nostrils, so that the filtering material can effectively heat the air inhaled into a nasal cavity, is attached to the inner layer of the nasal cavity of a human body, has excellent comfort, can effectively filter allergens such as fog-haze, sand storm, dermatophagoides farinae, pollen floccules and like, is completely built in the nasal cavity to hide, and has characteristics of convenient use, no influence on attractiveness and promotion of interpersonal communication.

Description

technical field [0001] The invention belongs to the technical field of woven fiber materials, and in particular relates to a preparation method of a built-in nasal cavity polyurethane filter material with antibacterial function. Background technique [0002] Smog, dust storms, dust mites, pollen, and hot and cold air circulation can all cause allergic rhinitis, which can cause a series of immune reactions, such as red, itchy and watery eyes, stuffy ears, decreased or lost sense of smell, and dizziness Headache, if not treated properly, is prone to concurrent bronchial asthma, which is extremely harmful to health. With the rapid development of industry, drastic changes in human life style and ecological environment, the incidence of allergic rhinitis is gradually increasing worldwide, and about 10%-25% of the world's population is affected by it, which has become a global health problem. question. [0003] At present, there is no effective method to completely cure allergic...

Invention patents such as CN1876202A, CN103933687A and CN106807001A report the built-in nasal plug filter. The product consists of a filter element, a base and auxiliary materials to form a frustum-shaped filter. less, the material has poor biocompatibility, and the product cannot be well attached to the inside of the nasal cavity, resulting in strong discomfort to the human body. The filtered harmful dust stays in the nasal cavity for a long time, does not have antibacterial function, and may easily cause skin allergies in the nasal cavity. Patent for invention CN104027905A, CN104117163A and CN105029771A introduce nano-silver fibers, nano-silver flakes and volatile drugs into the built-in filter, and there is a silica gel strip connecting the two nasal built-in filters. Although it has antibacterial function, the connecting part is still stuck at the lower end of the nostril , the shape of the product cannot fit the skin inside the nasal cavity well, and it is inconvenient to wear. The product is not only complicated in process, expensive in cost, but also does not have energy storage and heating performance. Nutritious cold air has no heating effect

[0006] As mentioned above, in the existing reports, no product has been found that can effectively filter the allergens of allergic rhinitis (smog, sandstorms, dust mites, pollen flocs, and hot and cold air circulation) and is easy to wear and beautiful without affecting normal communication and communication products
