▎ 摘　　要

NOVELTY - A heat insulating material comprises cement-based block skeleton comprising cavities filled with graphene-modified polystyrene. The graphene-modified polystyrene is formed by melt-extruding graphene and polystyrene in a weight ratio of 1:1-5 in the presence of an alkali foaming agent. USE - Heat insulating material. ADVANTAGE - The heat insulating material has improved strength and excellent heat preservation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the heat insulating material.
