NOVELTY - Preparation of aqueous polyurethane coating adhesive involves dispersing graphene oxide and nano-halloysite in solvent, stirring and dispersing at room temperature to obtain dispersion liquid, adding reducing agent to dispersion, heating, adjusting pH to 8-12, stirring to obtain mixed slurry, mixing dispersant and ultrasonically stirring for 4-8 hours, reducing temperature, filtering obtained product, washing, drying and grinding and dispersing in water to obtain aqueous dispersion of graphene- nano-halloysite hybrid and mixing with aqueous polyurethane solution, thickener and wetting agent. USE - Preparation of aqueous polyurethane coating adhesive for outdoor tent cloth (claimed). ADVANTAGE - The polyurethane coating adhesive has excellent water pressure resistance and fire resistance. The method is simple, economical and effective.
