▎ 摘　　要

NOVELTY - Preparing fabric using heat-retardant coating comprises (i) providing a concentration of 8.5-17.5 mg/ml graphene oxide sol, (ii) mixing uniformly montmorillonite and water, obtaining montmorillonite suspension, (iii) mixing the montmorillonite suspension, graphene oxide sol and thickening agent, to obtain graphene oxide doped montmorillonite coating agent, and (iv) applying to the surface of the fabric, to obtaining the fabric with flame retardant coating. USE - The method is useful for Preparing fabric using heat-retardant coating (claimed). ADVANTAGE - The method is simple synthesis process, easy operation, and it is green and environmentally-friendly, and suitable for mass production; can fully exert the excellent flame retardant property of graphene oxide and montmorillonite; and improves the fabric heat resistant.
