Description

technical field [0001] The invention relates to the field of building materials, in particular to a graphene fiber heat-insulating grid cloth and a preparation method thereof. Background technique [0002] At present, the building insulation construction mainly uses two building materials of thermal insulation steel wire mesh or thermal insulation mesh cloth as structural reinforcement. According to the design requirements, in general, thermal insulation steel wire mesh is used when the external wall is tiled, and thermal insulation is used when the external wall is painted. grid cloth. The corrosion-resistant service life of the thermal insulation wire mesh is only 5-7 years, and the thermal expansion and contraction are quite different from the elastic modulus of the crack-resistant mortar, which will cause large-scale cracking or even falling off of the crack-resistant surface layer; the thermal insulation mesh cloth has investment Less, simple maintenance, easy temperat...
