The invention discloses a high-temperature-resistant self-sintering nano-plate and a preparation method thereof, and relates to the technical field of energy-saving materials. The high-temperature-resistant self-sintering nano-plate is prepared by mixing and pressing various fine powders and fibers, and is prepared from 80-90 parts of the fine powders and 5-15 parts of the fibers, wherein the finepowders are composed of 20-60 parts of silicon micro-powder, 20-80 parts of white carbon black and 1-10 parts of rho-Al2O3, and the fibers comprise 1-10 parts of high silica glass fibers. By adding apart of rho-Al2O3 and white carbon black, the nano-plate has the performance of resisting high temperature of more than 1500 DEG C, has excellent heat preservation and insulation effects and higher refractoriness, and after high-temperature sintering, rho-Al2O3 reacts with white carbon black to generate a mullite reticular structure and generate certain strength, so that the phenomena of strengthreduction and pulverization of the nano-plate in the use process are prevented.
本发明公开了一种耐高温自烧结纳米板及其制备方法，涉及节能材料技术领域。由各种细粉、纤维混合压制而成，以质量份配比计，其制备原料如下：细粉为80‑90份，纤维为5‑15份，其中细粉是由硅微粉、白炭黑以及ρ‑Al2O3组成，所述纤维为高硅氧玻璃纤维，所述细粉：硅微粉20‑60份、白炭黑20‑80份、ρ‑Al2O3 1‑10份，所述纤维：高硅氧玻璃纤维1‑10份。该耐高温自烧结纳米板及其制备方法，添加部分ρ‑Al2O3及白炭黑，使得纳米板产生耐高温＞1500℃的性能，具有优异的保温隔热效果，同时耐火度较高，同时高温烧结后，ρ‑Al2O3自与白炭黑发生反应，生成莫来石网状结构，产生一定的强度，放止纳米板在使用过程中出现强度变低、粉化现象。
