▎ 摘  要

NOVELTY - Foaming material, comprises 20-95 pts. wt. PBAT resin, 5-80 pts. wt. thermoplastic elastomer, 0.5-10 pts. wt. bridging agent, 0.2-3 pts. wt. anti-hydrolysis agent, 0.1-2 pts. wt. foam pore regulator and 2-20 pts. wt. wave-absorbing auxiliary agent, where the bridging agent is ethylene-methyl methacrylate copolymer, nitrile rubber, vinyl triethoxy silane and styrene-glycidyl methacrylate copolymer. USE - Used as foaming material. ADVANTAGE - The material: is capable of degrading; has excellent high-resilience and wave-absorbing effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the foaming material, comprising (i) mixing PBAT resin with a thermoplastic elastomer, a bridging agent, an anti-hydrolysis agent, a foam pore regulator and a wave-absorbing auxiliary agent, and then sequentially carrying out melting, extrusion, press polishing and shaping to obtain a plate blank, (ii) placing the plate blank into a die cavity and performing supercritical foaming to obtain a primary foaming material, and (iii) carrying out hot-pressing and shaping on the primary foaming material to obtain the product.
