▎ 摘　　要

NOVELTY - Flame-retardant graphene polyurethane composite sponge material comprises the following raw material in terms of parts by weight: 40-60 pts. wt. polyol, 10-30 pts. wt. polyisocyanate, 2-10 pts. wt. graphene, 5-15 pts. wt. silicon dioxide-coated conductive carbon black, 2-10 pts. wt. flame retardant containing aluminum, 0.01-3 pts. wt. foaming agent. USE - Flame-retardant graphene polyurethane composite sponge material is used in mattresses, sofa cushions, or heating blankets (claimed). ADVANTAGE - The flame-retardant graphene polyurethane composite sponge material has excellent flame retardance, conductivity, and electro-thermal conversion efficiency, at the same time, exhibits high strength, high elasticity, and good thermal conductivity, suitable for a functional mattress with high performance, sofa cushion, or electric heating pad and other household articles, application prospect is very wide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the inflaming retarding graphene polyurethane composite sponge material, which involves: (A) mixing and dispersing polyol, graphene, silicon dioxide-coated conductive carbon black, aluminum-containing flame retardant, and optionally dispersing agent to obtain the polyol slurry; (B) uniformly mixing the polyalcohol slurry with the foaming agent to obtain component A; and (C) uniformly mixing the component A with the polyisocyanate and then entering the continuous foaming production line to react to obtain the flame-retardant graphene polyurethane composite sponge material.
