Abstract

The invention belongs to the field of fireproof materials and provides a graphene-based fireproof plastic plate. The graphene-based fireproof plastic plate comprises a graphene-based fireproof layer and a plastic base material layer, and the graphene-based fireproof layer comprises intrinsic graphene. Flame retardation and heat insulation effects of the fireproof layer can be improved by intrinsicgraphene, the plastic base material layer can be effectively protected in fire accidents, and burning and toxic gas releasing time of the plastic base material layer is delayed to buy time for evacuation and rescue. Further, stretch resistance and flexibility of the fireproof layer can be improved by intrinsic graphene, and the fireproof layer deforms correspondingly in deformation of the plasticbase material layer so as to keep high adhesion to the plastic base material layer; strength of an expansion carbon layer is improved, and less proneness to shedding after heat deformation of the plastic base material layer is realized. Owing to excellent insulation and hydrophobic performances of intrinsic graphene, water resistance of the fireproof layer can be remarkably improved, and the service life of the fireproof plastic plate is prolonged. In addition, the graphene-based fireproof plastic plate is low in density.
