NOVELTY - Preparing high wear-resistant thermoplastic polyurethane composite material by (i) preparing graphene oxide doped molybdenum disulfide composite material, (ii) placing the product into three-necked flask containing ethanol, ultrasonically treating, adding KH550 (RTM: gamma -Aminopropyltriethoxysilane), reacting, performing hydrolysis-condensation reaction to form net-like silicon dioxide structure that coats the surface of the composite material and introducing amino groups to obtain aminated graphene-based nanomaterials, cooling to normal temperature, washing with ethanol and water and freeze-drying, (iii) placing the product into three-necked flask filled with dimethylformamide solvent, adding appropriate amount of self-made epoxy resin with monoepoxy group and stirring for period of time and drying to obtain functional additive and (iv) adding the product to the polymerization to prepare f-GOMH/thermoplastic polyurethane (TPU) composite material. USE - Method for preparing high wear-resistant thermoplastic polyurethane composite material (claimed). ADVANTAGE - The method has excellent mechanical properties and wear resistance. DETAILED DESCRIPTION - Method for preparing high wear-resistant thermoplastic polyurethane composite material by (i) preparing graphene oxide doped molybdenum disulfide composite material, (ii) placing the product obtained in the step (i) into a three-necked flask containing 200 ml absolute ethanol, ultrasonically treating for 30 minutes, adding required amount of KH550 (RTM: gamma -Aminopropyltriethoxysilane), and reacting at 78 degrees C for 4 hours, performing hydrolysis-condensation reaction to form a net-like silicon dioxide structure that coats the surface of the composite material and introducing amino groups at the same time to obtain aminated graphene-based nanomaterials, cooling it to normal temperature, washing with a large amount of absolute ethanol and deionized water and freeze-drying, (iii) placing the product obtained in the step (ii) into a three-necked flask filled with dimethylformamide solvent, adding appropriate amount of self-made epoxy resin with monoepoxy group and stirring for a period of time, after washing with a large amount of dimethylformamide and drying in an oven at 60 degrees C to obtain functional additive functional graphene oxide modified by Hummers method (f-GOMH) and (iv) adding the product obtained in the step (iii) to the polymerization of TPU to prepare f-GOMH/ thermoplastic polyurethane (TPU) composite material.
