▎ 摘　　要

NOVELTY - Preparation method of polymer composite material involves (a) cleaning and drying a surface of a combustible polymer material, (b) soaking the dried polymer material in aqueous graphene oxide solution and drying at low temperature, (c) soaking the dried graphene oxide coated polymer material in silicone resin/catalyst mixed solution, and (d) rotating the soaked polymer composite foam material to remove excess solution, putting into a drying oven, curing at 60-100 degrees C for 2-10 hours and cooling to obtain composite material. USE - Method is useful for the preparation of polymer composite material (claimed). ADVANTAGE - The method enables preparation of polymer composite material with excellent high temperature resistance, synergistic effect, flame-retardant property, fireproof performance and physical property.
