Quartz fiber heat insulating material covered with aluminum film

The utility model discloses a quartz fiber heat insulating material covered with an aluminum film and relates to the field of heat insulating materials. The heat insulating material comprises a quartz fiber cloth, the quartz fiber cloth is covered with an aluminum film layer, an inorganic adhesive layer is arranged between the aluminum film layer and the quartz fiber cloth, and the aluminum film layer adheres to the quartz fiber cloth through the inorganic adhesive layer. The quartz fiber cloth is formed by weaving quartz fiber yarn with the diameter of 6-11 microns and the linear density of 195 tex, the outer surface of the quartz fiber cloth is of a plain structure, a twill structure or a satin structure, the thickness of the quartz fiber cloth is 0.1-0.5 mm, and the thickness of the aluminum film layer is 5-30 microns. The quartz fiber cloth can adhere to the aluminum film layer and the air tightness is good; the aluminum film layer can prevent high-temperature air from penetrating the heat insulating material, the heat insulation capability and the waterproof capability of the heat insulating material can be effectively improved; and the quartz fiber cloth and the aluminum film layer are good in folding resistance and toughness and can reduce production cost and use cost.
