▎ 摘　　要

NOVELTY - Nylon/polyurethane supercritical foamed complex material comprises 300-350 pts. wt. polyamide, 60-72 pts. wt. polyurethane, 40-48 pts. wt. polyamide-polysiloxane multi-block copolymer, 6-8 pts. wt. graphene fiber, 5-7 pts. wt. cross-linking agent, 3-4 pts. wt. nucleating agent, where the the polyamide is 65-72 wt.% terephthaloyl dodecane diamine-m-phthaloyl dodecane diamine copolyamide and polysebacylhexamethylene diamine (remaining amount). USE - Used as nylon/polyurethane supercritical foamed complex material. ADVANTAGE - The material: is uniform, small, and dense; has high rebound rate, low water absorption, excellent dimensional stability, tensile strength, mechanical property, foaming efficiency and small irreversible deformation after compression. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing a nylon/polyurethane supercritical foamed complex material comprising (i) taking polyamide, polyurethane, and polyamide-polysiloxane multi-block copolymer, graphene fiber, cross-linking agent and nucleating agent, (ii) taking polyamide, polyurethane, polyamide-polysiloxane multiblock copolymer, mixing graphene fibers, sending to an internal mixer, and performing the internal mixing for 12-14 minutes at a temperature of 115-120 degrees C, adding cross-linking agent and nucleating agent under temperature of 123-125 degrees C, carrying out mixing until the components are mixing uniformly to prepare a mixing blend, (iii) compressing the blended blend into sheet with tablet pressing and cutting, (iv) placing the resultant sheet into an oven and preheating to the foaming temperature, placing the pre-heated foamed sheet into high temperature mold, passing in the carbon dioxide gas, when the carbon dioxide gas reaches saturation in the sheet quickly release the carbon dioxide gas in the mold to form a sheet.
