Tensile protective film with heat insulation function

The tensile protective film with the heat insulation function comprises a base layer, a heat insulation layer, a flame retardant layer, a corona layer and an antistatic layer are sequentially arranged on the upper surface of the base layer, and a reinforcing layer and an adhesive layer are sequentially arranged on the lower surface of the base layer. The base layer comprises a hollow heat insulation layer and PET films arranged on the two sides of the hollow heat insulation layer, the heat insulation layer is made of nanoscale carbon sponge, the two sides of the nanoscale carbon sponge are connected with the base layer and the flame-retardant layer through silica gel layers respectively, the flame-retardant layer is a polyimide film layer, and the flame-retardant layer is a polyimide film layer. And flame retardants are arranged on two sides of the polyimide film layer. The heat-insulating and flame-retardant fabric is novel in design, simple in structure and convenient to use, and not only has good heat-insu
