Abstract

The invention particularly relates to nano compound function fibers as well as a preparation method and application thereof and belongs to the field of preparation of nano fibers. The nano compound function fibers are prepared from the following raw materials in parts by weight: 12-25 parts of a biological macromolecular degradable material, 10-15 parts of an inorganic material, 3-5 parts of a silane coupling agent, 60-70 parts of an organic polymer material, 1-3 parts of nano far infrared powder, 0.05-0.08 part of metal salt, 0.1-1 part of carotenoid and 0.05-0.5 part of calcium carbonate. The nano compound function fibers are prepared by the following steps: mixing the raw materials to prepare melted liquid and adopting a high-pressure electrostatic spinning method. The nano compound function fibers are sprayed on the inner surface or the outer surface of a filter element so that the filtering precision of a traditional filter element is improved and the filtering efficiency is improved; the nano compound function fibers have the effects of nano fiber sterilization, water quality activation and the like; and when the nano compound function fibers are sprayed on the inner surface or the outer surface of the filter element, the filtering quality of the filter element is extremely prolonged.

Description

technical field [0001] The invention belongs to the field of preparation of nanofibers, and in particular relates to a nanocomposite functional fiber and its preparation method and application. Background technique [0002] The filter element is the heart of the filter and the main principle of the filter. It is the purification equipment needed to purify the original ecological resources and reuse the resources. The filter element is generally used in oil filtration, water filtration, air filtration, etc. industry. Removing a small amount of impurities in the filter medium can protect the normal operation of the equipment or the cleanliness of the air. When the fluid passes through the filter element with a certain precision in the filter, the impurities are blocked, and the clean fluid flows out through the filter element. [0003] Wire wound filter elements, PP meltblown filter elements, pleated filter elements, large flow filter elements, etc. in the water filter elemen...
