▎ 摘　　要

NOVELTY - Flexible graphene non-woven fabric heating material comprises heating material which is a composite powder uniformly mixed with graphene oxide powder and glass powder, and heated to be completely melted to obtain a liquid melt. The melt is added to a centrifuge equipped with micro-holes protected by nitrogen, centrifuged at high speed and cooled into filaments, wound into piles, and continuously drawn by the traction roller and pressed to form a composite, and reduced by the hydrazine hydrate reduction treatment. USE - Flexible graphene non-woven fabric heating material. ADVANTAGE - The flexible graphene non-woven fabric heating material is high temperature resistance, aging resistance, stable structure, good heating effect, simple preparation equipment, easy control of the process, which is conducive to large-scale production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a flexible graphene non-woven fabric heating material, which involves: (A) adding graphene oxide powder and glass powder to a high-speed mixer, stirring and dispersing at high speed to obtain a composite powder of graphene oxide and glass powder; (B) heating composite powder of graphene oxide and glass powder to completely melt the glass powder, and dispersing graphene oxide in the completely melted glass melt to obtain a liquid melt; (C) adding liquid melt to the centrifuge with nitrogen protection, setting centrifuge with micropores, and centrifuge works at high speed, throwing melt from the micropores, cooled into filaments, and winding into velvet, continuously drawing by the traction roller, and shapping by the roller to obtain a composite of loose felt-like graphene oxide and glass powder; and (D) subjecting composite of the loose felt-like graphene oxide and glass powder to roller setting, and reducing and collecting by hydrazine hydrate to obtain a flexible graphene non-woven fabric heating material.
