Abstract

The invention discloses a non-slip thermoplastic polyurethane composite material and a preparation method thereof, and belongs to the field of polymer composite materials. The composite material comprises the following raw materials in parts by weight: 97-100 parts of thermoplastic polyurethane, 1-7 parts of an anti-slip agent RGO-HCA, 20 parts of a self-made plasticizer, and 3 parts of C5 hydrogenated petroleum resin. The anti-slip agent RGO-HCA is a graphene-based nano composite material, and is prepared by epoxidizing the surface of graphene oxide by using epoxy chloropropane and then grafting citric acid; and the plasticizer is prepared from polylactide polyol with the molecular weight of 1000 and p-toluene sulfonyl isocyanate. The anti-slip agent RGO-HCA, the self-made plasticizer, the C5 hydrogenated petroleum resin and TPU particles are uniformly mixed, granulation and injection molding are performed to obtain the TPU composite material with excellent anti-slip performance, and the TPU composite material is predicted to have a great application prospect.

Description

technical field [0001] The invention belongs to the field of thermoplastic polyurethane composite materials, and in particular relates to an anti-slip thermoplastic polyurethane composite material and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane elastomer, referred to as TPU, is a new type of organic polymer synthetic material. Due to its special structure, TPU has many excellent properties, such as good wear resistance, high tensile strength, high compressive strength, high tear strength, good flexibility and good stability, etc. Compared with ordinary polyurethane, it has better properties. Compared with rubber, it has better aging resistance and is the most ideal material that can replace PVC and PU at present. The anti-slip performance of the sole directly affects the comfort and safety of the shoe when it is worn. When TPU is used as the outsole of shoe materials, it has poor anti-slip performance, and it is easy to slip and w...
