NOVELTY - Preparing composite filler reinforced nylon involves performing amination of titanate which is modified with amino-terminated silane coupling agent, adjusting pH to 3-4 with 1-2 mol/L acidic solution, and ultrasonically stir to obtain uniform titanate dispersion; adding titanate dispersion to graphene oxide aqueous solution to prepare graphene/titanate composite powder; mixing graphene/titanate composite powder and diamine ultrasonically in aqueous solution, and after mixing is complete, performing suction filtration, water washing, and finally drying in vacuum drying cabinet to obtain ammonium carboxylate; dissolving glutaric acid and adipic acid in aqueous solution, and placing salt solution in autoclave, where reaction temperature is 230-250 degrees C, and reaction pressure is 1.5-3.5 Megapascal; reacting for 1-2 hours to obtain prepolymer of nylon material. USE - Method for preparing composite filler reinforced nylon. ADVANTAGE - The method enables to prepare composite filler reinforced nylon, which improves stability of nylon and solve shortcomings of nylon material's poor heat resistance and low impact strength.
