High-temperature-resistant heat-insulating fiber composite material and preparation method thereof
The invention relates to the technical field of heat-insulating fiber materials, in particular to a high-temperature-resistant heat-insulating fiber composite material and a preparation method thereof. According to the structure, bonded fiber sheet layers are arranged on the two surfaces of a titanium/silicon/carbon inorganic composite nanofiber membrane layer; the preparation method comprises the following steps: (1) carrying out electrostatic spinning and calcining to obtain a titanium/silicon/carbon inorganic composite nanofiber membrane layer; (2) preparing slurry, and carrying out papermaking on a net to obtain a wet sheet base; the slurry comprises aluminum silicate fibers, an infrared blocking agent, a binder and water; the infrared blocking agent is potassium hexatitanate whisker and zirconium oxide; and (3) sequentially laminating the wet substrate, the titanium/silicon/carbon inorganic composite nanofiber membrane layer and the wet substrate, pressing, dehydrating, drying and curing to obtain the high-temperature-resistant heat-insulating fiber composite material. The material provided by the invention has good tensile strength, can resist high temperature of 1450 DEG C, and has a normal temperature heat conductivity coefficient of 0.025 W/m.K or less.
