NOVELTY - Preparing modified thermoplastic polyurethane resin, involves weighing 25-35 pts. wt. thermoplastic polyurethane and 0.2-1 pts. wt. graphene sheet grafted layered double hydroxide, uniformly mixing, and carrying out melt blending in a mixing roll to obtain the modified product. USE - Method for preparing modified thermoplastic polyurethane resin. ADVANTAGE - The analysis of mechanical properties shows that with increase of amount of graphene grafted layered double hydroxide, and further increases tensile strength of the modified thermoplastic polyurethane resin. The graphene sheet grafted layered double hydroxide has obvious reinforcement effect on the matrix TPU (thermoplastic polyurethane).
