NOVELTY - The utility model claims a concrete structure with graphene-proof heat-insulating layer, which mainly uses the concrete layer as the outer wall of a building, making polyurethane graphite layer coated on the outer surface of the concrete layer. graphene (Graphene) the polyurethane graphene layer by weight percentage is 70 %-99 % of a polyurethane (PU, PU) and the weight percentage is 1 %-30 % of the mixture, then mortar layer is coated on the outer surface of the polyurethane graphene layer. the mortar layer is formed by mixing of sand, cement and water; therefore, it not only can effectively isolate the outdoor heat conduction into the indoor space, and can make the heat in the indoor space quickly absorb radiated outwards, reducing the temperature in the indoor space, so that people can comfortably be in the indoor space, and the use is more practical efficacy characteristics increasing in its entirety.
