▎ 摘　　要

NOVELTY - High resilience and antibacterial foam material comprises 100 pts. wt. thermoplastic polyurethane material, 10-20 pts. wt. nylon elastomer, 1-2 pts. wt. antibacterial agent, 1-2 pts. wt. stearic acid, 1-2 pts. wt. crosslinking agent and 2-4 pts. wt. blending agent. USE - Used as high resilience and antibacterial foam material. ADVANTAGE - The material improves the thermal stability of the antibacterial agent in the TPU foam material; solves the problem of poor dispersion of graphene or chitosan single-component antibacterial agent in the matrix resin; ensures problem of agglomeration affecting material properties is prone to occur; reduces the influence of the addition of inorganic antibacterial agents on the elastic properties of foamed materials; and can effectively maintain and improve the elastic properties of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing foam material comprising (i) taking TPU material, nylon elastomer, antibacterial agent, stearic acid, crosslinking agent, and blending agent; (ii) adding TPU material, nylon elastomer, antibacterial agent, stearic acid, crosslinking agent, and blending agent to the high-speed mixer in sequence, and mixing at high speed to obtain a premix; (iii) adding premix to the twin-screw extruder, and go through the processes of supercritical carbon dioxide injection, shear mixing, pressure-reducing extrusion, heating foaming, cooling and shaping, etc., to obtain high resilience and antibacterial TPU foam material.
