Description

technical field [0001] The invention belongs to the field of building thermal insulation materials, and in particular relates to a graphene nano-corrosion-resistant fireproof and thermal insulation material. Background technique [0002] Graphene is one of the materials with the highest strength known, and it also has good toughness and can be bent. The theoretical Young's modulus of graphene reaches 1.0TPa, and its inherent tensile strength is 130GPa. The reduced graphene modified by hydrogen plasma also has very good strength, and the average modulus can be greater than 0.25TPa. Graphite paper composed of graphene flakes has many pores, so graphite paper is very brittle. However, functionalized graphene obtained through oxidation, and then graphite paper made from functionalized graphene will be extremely strong and tough. Applying the excellent mechanical properties of graphene to the field of building insulation materials can greatly improve the mechanical strength of c...
