Nano thermal insulation material and preparation method thereof
The invention provides a nanometer thermal insulation material and a preparation method thereof, and the nanometer thermal insulation material comprises the following components: 3-9% of a reinforced fiber membrane, 5-10% of nanopore silicon-doped carbon fiber, 5-10% of an opacifying agent, and the balance of modified silica fume with the particle size of 10-100 nm. Wherein the structure of the nanopore silicon-doped carbon fiber is a spiral structure. The preparation method comprises the following steps: uniformly mixing the reinforced fibers, the modified silica fume, the opacifying agent and the nanopore silicon-doped carbon fibers in a high-speed stirrer; and performing dry pressing to obtain a sample, and drying the sample in a drying oven. According to the nanometer heat insulation material and the preparation method thereof, on the premise that the heat insulation effect is not influenced or even improved, the nanometer heat insulation material which is good in heat insulation performance, still efficient in heat insulation performance under the high-temperature condition and good in mechanical property is obtained by taking the micro-silicon powder as a matrix raw material and taking the reinforced fiber membrane and the nanometer hole silicon-doped carbon fiber as reinforcements.
