| titleOfInvention | A kind of method for continuously preparing carbon fiber from acrylic fiber |
| abstract | The invention relates to the technical field of carbon fiber preparation, in particular to a method for continuously preparing carbon fibers from acrylic fibers, comprising the steps of: continuously impregnating the acrylic fibers with a modification solution, and continuously entering the impregnated acrylic fibers into a pre-oxidation furnace, a low-temperature carbonization furnace and a high-temperature The carbon fiber is obtained by heat treatment in a carbonization furnace; the modified solution is a solution containing dopamine organic compounds; the present invention adopts a low concentration dopamine organic compound solution to impregnate the acrylic fiber, which can effectively reduce the initial temperature of the chemical reaction in the preoxidation furnace, greatly reducing the The reaction emits heat, which promotes the reaction to be more gentle, prevents the fiber from burning due to instantaneous rapid heat release, etc., and the immersion time of the acrylic fiber in the modified solution is short, which can realize the continuous production of carbon fiber and significantly reduce the production cost. It has potential significance in the field of industrialized production of cost carbon fiber. |
