Preparation method of high-performance flame-retardant fibers

Abstract

The invention relates to a preparation method of high-performance flame-retardant fibers. The preparation method comprises the following steps of dispersing polyacrylonitrile into a mixed solvent of water and ethanol to obtain sol, then carrying out electrostatic spinning, collecting at low temperature to obtain mesoporous nanofibers, then immersing the mesoporous nanofibers into silver-doped nano titanium dioxide hydrosol to carry out modification treatment, and then dispersing in a mixed solvent of ethanol and water, and adding ethyl silicate, vinyltriethoxysilane and ammonia water for reaction to obtain the high-performance flame-retardant fiber material with antibacterial, environment-friendly and high flame-retardant properties.

Description

technical field

[0001] The invention relates to the field of preparation of heat-insulating and flame-retardant fibers, in particular to a method for preparing high-performance flame-retardant fibers. Background technique

[0002] Flame-retardant fiber is the basic material for preparing textiles with flame-retardant effects. Commonly used flame-retardant textiles such as curtains, mattresses, automotive interiors, furniture, and automobiles generally have a certain amount of formaldehyde due to the application of polymer materials. And long-term use is prone to bacteria, and the fire resistance performance requirements of materials are also higher; with the rapid development of my country's furniture and automobile markets, safety, environmental protection, and hygiene have gradually become important factors for consumers to consider. And fiber materials with high flame-retardant properties have a broad application market.
