▎ 摘　　要

NOVELTY - Method for preparing high-temperature resistant layer cloth, involves (i) taking graphene, ethyl orthosilicate and absolute ethanol, mixing and stirring into a jelly, adding an aqueous hydrogen peroxide solution to the jelly and stirring to obtain a graphene oxide polymer solution, (ii) adding water-soluble chitosan, aqueous acrylate solution and citric acid to the graphene oxide polymer solution and stirring to obtain a porous graphene oxide flame retardant solution, and (iii) adding silicate, fiber and polyvinyl alcohol to the porous graphene oxide flame retardant solution, stirring, preparing a spinning glue, using the spinning glue to make fiber thread, and spinning the fiber thread into a high-temperature resistant layer cloth. USE - The method is useful for preparing high-temperature resistant layer cloth for preparing flame-retardant fabric (all claimed). ADVANTAGE - The high-temperature resistant layer cloth and the flame-retardant fabric have excellent flame-retardant effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing flame-retardant fabric, which involves adopting the method for preparing a high-temperature resistant layer cloth to make a high-temperature resistant layer cloth, taking the fabric layer cloth, using a thermoplastic polyurethane rubber to bond the fabric layer cloth and the high temperature resistant layer cloth, and subjecting to UV radiation.
