High-strength high-temperature-resistant ceramic fiber elastomer thermal insulation material as well as preparation method and application thereof
The invention relates to a high-strength high-temperature-resistant ceramic fiber elastomer thermal insulation material and a preparation method and application thereof.The method comprises the steps that a first part of ceramic micron fibers, a graphene oxide solution, a surfactant and water are evenly dispersed, and then a reducing agent and a silicone rubber prepolymer are added and evenly dispersed; adding a second part of ceramic micron fibers after pre-reduction reaction, uniformly dispersing, and then carrying out reduction reaction to obtain ceramic micron fiber/graphene composite wet gel; soaking the wet gel in water, and then carrying out wet pressing; and after wet pressing, pre-freezing, freeze-drying and annealing treatment are performed in sequence to obtain the high-strength high-temperature-resistant ceramic fiber elastomer thermal insulation material. The maximum compression strength of the prepared elastic thermal insulation material under 10% compression deformation can reach 0.75 MPa, the long-time temperature resistance can reach 1300 DEG C, and the elastic thermal insulation material can be used as a high-strength high-temperature-resistant elastic reinforcement material of a conventional elastic aerogel material and can also be independently used as a high-strength high-temperature-resistant elastic thermal insulation material.
本发明涉及一种高强度耐高温陶瓷纤维弹性体隔热材料及其制备方法和应用，所述方法：将第一部分陶瓷微米纤维、氧化石墨烯溶液、表面活性剂和水分散均匀，然后加入还原剂和硅橡胶预聚物并分散均匀，经预还原反应后加入第二部分陶瓷微米纤维并分散均匀，再经还原反应，得到陶瓷微米纤维/石墨烯复合湿凝胶；将所述湿凝胶浸泡在水，然后进行湿压；在湿压后，依次进行预冷冻、冷冻干燥和退火处理，得到高强度耐高温陶瓷纤维弹性体隔热材料。本发明所制备的弹性隔热材料在10％压缩形变下压缩强度最大可达0.75MPa、长时耐温达1300℃，既能作为常规弹性气凝胶材料的高强度耐高温弹性增强体材料，也可单独作为高强度耐高温弹性隔热材料。
