NOVELTY - The utility model claims a composite stain-resistant film field, claims a composite stain-resistant film with good stain resistance, comprising a film rolling roller, the roller body of the film rolling roller is wound with a stain-resistant layer main body, the upper end of the stain-resistant layer main body is fixedly connected with a graphene layer, the upper end of the graphene layer is fixedly connected with a polyvinyl alcohol layer, the lower end of the stain-resistant layer main body is fixedly connected with a reinforcing layer. In the utility model, graphene layer and polyvinyl alcohol layer have high hydrophilicity, good stain resistance and film-forming property, so as to greatly improve the antifouling capability of the composite stain-resistant film, at the same time, using the high performance fiber material by the reinforcing layer, the setting of the material greatly improves the tensile resistance of the composite stain-resistant film, at the same time, it does not affect the flexibility of the composite stain-resistant film itself, at the same time, the wear-resistant coefficient and service life of the composite stain-resistant film can be greatly improved by the nanometer scratch-resistant coating, so as to further improve the practical performance of the composite stain-resistant film.
