Abstract

The invention discloses a butadiene rubber micro-nano fiber based on a solution jet spinning method, which belongs to the field of industrial textiles. The method of the present invention comprises the steps of: (1) adding a photoinitiator and a crosslinking agent in the butadiene rubber solution, stirring to obtain a spinning stock solution; wherein the mass ratio of the photoinitiator to the butadiene rubber is 0 ~20:100, but not 0; the mass ratio of crosslinking agent to butadiene rubber is 0~20:100, but not 0; (2) spinning the spinning dope by solution jet spinning method, The butadiene rubber fibers are irradiated and cured by ultraviolet lamps during the spinning process. The invention adopts the solution injection technology to prepare butadiene rubber micro-nano fibers, the production operation is flexible and simple, the single-hole extrusion rate is several times higher than that of electrospinning, and the multi-hole nozzle can be used for spinning, the production efficiency is high, and the method is suitable for industrial production.

Description

technical field

[0001] The invention relates to a butadiene rubber micro-nano fiber based on a solution jet spinning method, which belongs to the field of industrial textiles. Background technique

[0002] As a new method of preparing micro-nanofibers, the solution jet spinning method has attracted extensive attention of researchers since it came out in 2009. It was first proposed by Medeiros et al. by combining the characteristics of the melt-blown method and the dry spinning method to prepare micro-nano fibers. The basic principle of this method is to use high-speed airflow to ultra-finely stretch the thin stream of solution, and solidify it into fibers with the evaporation of solvent. Polymer fibers that have been successfully prepared by solution jet spinning include polyvinyl alcohol (PVA), polyacrylonitrile (PAN), polyethersulfone (PES), polyurethane (PU), polyethylene glycol (PEG), meta Aramid (MPIA), polyether ether ketone (PEEK), polymethyl methacrylate (PMMA), po...
