Air filtering material with sterilization and disinfection functions

Abstract

The invention belongs to the field of air filtering materials and in particular relates to an air filtering material with sterilization and disinfection functions. The air filtering material is prepared from the following raw materials in parts by weight: 100-300 parts of cordate houttuynia, 50-150 parts of fennel, 100-300 parts of cassia twig, 100-300 parts of eupatorium, 100-300 parts of illicium verum, 50-150 parts of mangnolia officinalis, 50-150 parts of angelica root, 50-150 parts of baical skullcap root and 600-1800 parts of edible vinegar (containing 4-6 percent of acetic acid). A preparation method of the air filtering material comprises the following steps of: a, respectively crushing the cordate houttuynia, the funnel, the cassia twig, the eupatorium, the illicium verum, the mangnolia officinalis, the angelica rot and the baical skullcap root in parts by weight into fine granules being about 20 meshes, and then sufficiently mixing the fine granules; and b, sufficiently and uniformly stirring the Chinese medicine mixture with 600-1800 parts of edible vinegar (containing 4-6 percent of acetic acid), and placing for 24 hours in an closed manner.

Description

technical field [0001] The invention belongs to the field of air filter materials, in particular to an air filter material with sterilization and disinfection functions. Background technique [0002] Air filter materials are mainly made of polyester, polyamide, polyacrylonitrile and other synthetic fibers and glass fibers from traditional silk, cotton and linen fibers. Air purifier filters or air conditioner filters made of these air filter materials The net is suitable for removing dust and other inhalable particles in the air and is not suitable for places that need to remove bacteria and viruses in the air, because if you want to use air filters to remove bacteria and viruses in the air, you must use a multi-channel filter device. Laminar flow cleaning system, but the disadvantages of laminar flow cleaning system are that the investment is large, the structure is complex, and the cost of use is also high, so its application range is sometimes very limited.

[0002] Air filter materials are mainly made of polyester, polyamide, polyacrylonitrile and other synthetic fibers and glass fibers from traditional silk, cotton and linen fibers. Air purifier filters or air conditioner filters made of these air filter materials The net is suitable for removing dust and other inhalable particles in the air and is not suitable for places that need to remove bacteria and viruses in the air, because if you want to use an air filter to remove bacteria and viruses in the air, you must use a multi-channel filter device. Laminar flow cleaning system, but the disadvantages of laminar flow cleaning system are that the investment is large, the structure is complex, and the cost of use is also high, so its application range is sometimes very limited. Environment) It is really necessary to sterilize the air. In the absence of a laminar flow cleaning system configuration, other sterilization methods are often used, such as ultraviolet disinfection, ozone disinfection and chemical disinfectant solution spraying or fumigation. It is a method that is convenient to use, has obvious effects and relatively low cost, but the fly in the ointment of using these methods to kill bacteria and viruses in the air is that it is not suitable for sterilization and disinfection operations when people are active, because if these places are used when people are active. Sterilization and disinfection, a little carelessness will cause harm to the human body
