▎ 摘  要

NOVELTY - Stretch-resistant graphene aerogel thermal insulation material comprises graphene oxide aerogel layer, graphene oxide-ethanol adhesive layer and modified glass fiber layer, where the graphene oxide-ethanol adhesive layer is two layers, which are respectively coated on both sides of the graphene oxide aerogel layer. The modified glass fiber layer is two layers, which are respectively adhered to the graphene oxide aerogel layer. The modified glass fiber layer includes chopped glass fibers. The graphene oxide aerogel layer comprises 40-60 pts. wt. graphene oxide, 450-500 pts. wt. aromatic amine, 230-260 pts. wt. concentrated ammonia water, ethanol and water. USE - Stretch-resistant graphene aerogel thermal insulation material used as a heat-insulating material, a heat reflecting material and a vacuum material. ADVANTAGE - The stretch-resistant graphene aerogel thermal insulation material has good heat insulation performance and high tensile modulus effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a stretch-resistant graphene aerogel heat insulating material, which involves: a. coating the graphene oxide-ethanol adhesive layer on one side of the graphene oxide aerogel layer, then sticking the glass fiber layer on the graphene oxide-ethanol adhesive layer, and drying to make the graphene oxide-ethanol adhesive layer and modified glass fiber layer; and b. sticking the modified glass fiber layer on the other side of the graphene oxide aerogel layer, and drying to obtain a product.
