Problems solved by technology

However, the current preparation method of graphene cannot be produced on a large scale, and the dispersion effect in polymers is not good, which limits the application of graphene in the field of polymer composites.
[0003] In the traditional process of producing fabric-film composites, the film and the pasting cloth are directly laminated, but this method will cause the stress generated by the film during the product

Abstract

The invention discloses a modified TPU film fabric compound and a preparation method thereof. The film fabric compound comprises a modified TPU surface film layer, a PU surface adhering layer, a polyethylene fiber modified nylon base fabric, a PU bottom adhering layer and a modified TPU bottom film layer which are sequentially arranged, wherein a TPU modifying agent and polyester type TPU resin are mixed and dried based on ratio and then are extruded and cast to form a film; finally, the obtained modified TPU film layer is preheated with the nylon base fabric which is subjected to dehumidifying, pasting and drying; the modified TPU film layer and the nylon base fabric are processed by opposite pressing, laminating and winding through two mirror roller surfaces. The traditional preparationtechnology of the film fabric compound is modified, and thus a novel production method and technology is provided to a graphene oxide modified TPU film fabric compound; moreover, the prepared film fabric compound is high in tensile strength, tearing intensity and stripping fastness, and also has the bacteria resistance and bacteriostasis performances.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a modified TPU film fabric compound and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly polymer material, TPU is widely used in medical, food, hygiene and other industries. Graphene is a new nanomaterial in the past 20 years. Due to its excellent performance, it has attracted attention in various fields. Adding graphene as a modifier to polymer materials will significantly improve the mechanical properties of polymer materials, especially tensile strength, elongation, tear strength, and friction resistance. However, the current preparation methods of graphene cannot be produced on a large scale, and the dispersion effect in polymers is not good, which limits the application of graphene in the field of polymer composites. [0003] In the traditional process of producing fabric-film composites, the film and the p...
