▎ 摘　　要

NOVELTY - Preparing graphene foam material, comprises (i) mixing polyol, water, silicone oil, metal catalyst, polyurethane auxiliary agent, foaming material catalyst to obtain mixture, adding isocyanate and graphene powder, continuously and effectively uniformly stirring for 15-20 seconds under the action of the unsaturated bond in the isocyanate to generate polyurethane elastomer; and (ii) adding the graphene powder and isocyanate, immediately pouring the mixture obtained by stirring into the mold, allowing to stand for 20-24 hours to obtain the graphene foam material. USE - The material is useful for insole or sole material, large-scale molds and small and medium-sized molds and in inner pad of sole space (all claimed). ADVANTAGE - The method enables to prepare graphene foam material that improves the blood circulation of the foot, enhances the metabolism of the immunity, and reduces the pain of human body. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use method of foam material for insole or sole material, large-scale molds and small and medium-sized molds and inner pad of sole space, comprising (a) cutting the graphene foam material for large-scale mold, slicing and molding again to make the required insole or mold sole material and If it is a small and medium-sized mold, then directly hot-mold and shape the graphene foam material to make the required insole or sole material, where the inner pad is made of the graphene foam material, and the inner pad is placed in the forefoot position of the sole, the position of the heel of the sole or the shoe cavity space of the sole.
