Zirconium-aluminum-based aerogel composite material and preparation method thereof
The invention relates to a zirconium-aluminum-based aerogel composite material and a preparation method thereof, the zirconium-aluminum-based aerogel composite material is prepared from the following raw materials: a zirconium source, an aluminum source, a coagulant and a composite material serving as a framework, and the molar ratio of the zirconium source to the aluminum source to the coagulant is 1: (0.5-1.5): (0.001-0.06); the composite material serving as the framework is completely soaked in zirconium-aluminum sol composed of a zirconium source, an aluminum source and a coagulant, and then the zirconium-aluminum-based aerogel composite material is formed through gelling and drying; the composite material prepared according to the scheme is high in heat insulation capacity, the change amplitude of the heat conductivity coefficient under the high-temperature condition is small, the use requirement under the harsh condition can be met, and the heat resistance is more stable.
一种锆铝基气凝胶复合材料及其制备方法，该材料的制备原料包括：锆源、铝源、促凝剂和充当骨架的复合材料，所述的锆源、铝源、促凝剂的摩尔比为1：(0.5～1.5)：(0.001～0.06)；所述的充当骨架的复合材料完全浸渍于锆源、铝源和促凝剂构成的锆铝溶胶中，然后经过凝胶、干燥形成锆铝基气凝胶复合材料；本申请的方案制备的复合材料其隔热能力强，高温条件下导热系数的变化幅度小，能够达到更苛刻条件下的使用要求，耐热性能更稳定。
