Problems solved by technology

[0005] The existing electrospun fibers and non-woven fabrics are mainly concentrated in the fields of shape control, filter materials, heat preservation and photoelectric material preparation.
At the same time, the heat-resistant temperature of most materials is low, so it is not suitable for high-temperature disinfection operations

Abstract

The invention discloses a high-temperature-resistant antibacterial nanofiber non-woven fabric and a preparation method and application thereof. The non-woven fabric is prepared from 51%-98.5% by weight of butene polymer, 0.05%-5% by weight of a bacteriostatic agent, 0.05%-5% by weight of an anti-aging agent, 0.05%-5% by weight of an antistatic agent, 0%-2% by weight of a coloring agent, 0%-2% by weight of a surfactant and 0% to 30% by weight of an inorganic filler. The non-woven fabric is formed by disorderly arranging multiple layers of superfine fibers with the diameter of 100-1000 nm, the thickness of the non-woven fabric is 5 microns to 1 centimeter, the non-woven fabric has inhibiting and killing effects on fungi, bacteria and viruses, the sterilization rate reaches 99.99%, and the virus inhibition rate reaches 99.99%. The non-woven fabric is prepared by adopting melt electrostatic spinning.

Description

technical field [0001] The invention belongs to the field of polymer superfine fiber non-woven fabrics, relates to electrospinning preparation technology, in particular to a butene polymer nanofiber non-woven fabric and its preparation method and application. Background technique [0002] High isotactic polybutene is a semi-crystalline polyolefin material with outstanding thermal creep resistance, stress cracking resistance, high heat resistance temperature, and high toughness. Polyolefin alloys (bottle alloys and physical blends) based on high isotactic polybutene not only have the advantages of polybutene, but also have the characteristics of another polyolefin. Polybutene is mainly used in pipes and can also be used in the field of film materials. [0003] Electrospinning technology is currently the most simple and effective method for preparing nanofibers, and the diameter of the prepared fibers can be between 10nm and 1000nm. In the electrospinning (electrospinning) p...
