Waterborne polyurethane/graphene flame-retardant anti-ultraviolet finishing agent as well as preparation method and application thereof

The invention provides a waterborne polyurethane/graphene flame-retardant anti-ultraviolet finishing agent as well as a preparation method and application thereof, and relates to the technical field of macromolecular finishing agents. The waterborne polyurethane/graphene flame-retardant anti-ultraviolet finishing agent is prepared by mixing flame-retardant anti-ultraviolet waterborne polyurethane and graphene, and when the waterborne polyurethane/graphene flame-retardant anti-ultraviolet finishing agent serves as a finishing agent to be used in the after-finishing process of fabric, the fabric can have good flame-retardant and anti-ultraviolet performance. Meanwhile, the finishing method provided by the invention is simple to operate, low in cost, good in finishing effect and high in fabric fastness, has great advantages in the aspects of preparation cost and product performance compared with the existing flame-retardant and anti-ultraviolet fabric, and has a good application prospect. 本发明提供了一种水性聚氨酯/石墨烯阻燃抗紫外整
