Thermal insulation composite material based on 3D printing ceramic frame and preparation method thereof
The invention discloses a thermal insulation composite material based on a 3D printing ceramic frame and a preparation method thereof, and relates to a thermal insulation material based on the 3D printing ceramic frame and a preparation method thereof. The invention aims to solve the technical problem that the existing aerogel thermal insulation material cannot have high strength and low thermal conductivity at the same time. Compared with traditional ceramic particle aerogel, the 3D printing ceramic frame can provide high strength and can also reduce weight, in-situ growth of mullite whiskers and filling of mullite fibers can fill pores of the ceramic frame, and on the basis that the original structure and performance of the ceramic frame are not damaged, the 3D printing ceramic frame can be used for 3D printing. A nanoscale pore structure formed by mutual crossing of mullite whiskers also endows the frame with excellent high-temperature heat insulation characteristics, so that the frame has high strength and low heat conductivity; the filled mullite fibers provide efficient fire prevention and heat insulation, and preparation of the emergency thermal runaway protection heat insulation sheet with high strength and high heat insulation is achieved.
一种基于3D打印陶瓷框架的隔热复合材料及其制备方法，涉及一种基于3D打印陶瓷框架的隔热材料及其制备方法。本发明是要解决现有的气凝胶隔热材料无法兼具高强度和低导热的技术问题。3D打印陶瓷框架相比于传统的陶瓷颗粒气凝胶在提供高强度的同时还可以减重，原位生长莫来石晶须以及填充的莫来石纤维能填充陶瓷框架的孔隙，在不破坏陶瓷框架原本结构和性能的基础上，莫来石晶须相互交叉形成的纳米级孔结构还赋予了框架优异的高温隔热特点，从而兼具高强度和低导热；填充的莫来石纤维提供高效的防火和隔热，实现对高强度和高隔热的应急热失控防护隔热片的制备。
