High-temperature-resistant bulked yarn glass fiber composite thermal insulation material

The utility model discloses a high-temperature-resistant bulked yarn and glass fiber composite thermal insulation material. The bulked yarn and glass fiber composite thermal insulation material comprises an aluminum foil layer, a bulked yarn and glass fiber layer and a heat reflection coating layer which are sequentially stacked. According to the composite thermal insulation material, the bulked yarn glass fibers are compounded with the aluminum foil layer and the heat reflection coating layer, and the composite structure is good in thermal protection, flame retardance, water resistance and corrosion resistance; gaps are increased after the yarns of the fabric are bulked, so that permeation of the heat reflection coating layer is facilitated, the adhesiveness of the heat reflection coating layer is improved, and the comprehensive heat insulation performance of the composite heat insulation material is improved; and the bulked yarn glass fibers and the aluminum foil layer are bonded more firmly and are not lay
