Metal honeycomb ceramic heat accumulator
The invention discloses a metal honeycomb ceramic heat accumulator, which is prepared from the following raw materials in parts by weight: 60 to 80 parts of mullite, 20 to 30 parts of corundum, 10 to15 parts of clay, 5 to 7 parts of silicon carbide, 30 to 40 parts of aluminum oxide, 30 to 40 parts of a glue, 5 to 10 parts of hydroxypropyl methyl cellulose HPMC, 22 to 35 parts of water and 5 to 7parts of graphene. According to the invention, the high temperature resistance, the corrosion resistance and the apparent porosity of the metal honeycomb ceramic heat accumulator prepared by the method are all higher than those of national standard requirements and are obviously superior to those of a contrast sample, so that the metal honeycomb ceramic heat accumulator has a wide application prospect; and the apparent porosity of the ceramic material can be further reduced by introducing graphene, aluminum oxide grains can be filled with the graphene, and the graphene has corrosion resistance, so that the heat accumulation performance of the metal honeycomb ceramic heat accumulator can be improved, and the metal honeycomb ceramic heat accumulator is suitable for popularization and application.
本发明公开了金属蜂窝陶瓷蓄热体，包括以下重量份的原料：莫来石60～80份、刚玉20～30份、粘土10～15份、碳化硅5～7份、氧化铝30～40份、胶水30～40份、羟丙基甲基纤维素HPMC 5～10份、水22～35份、石墨烯5～7份。本发明制得的金属蜂窝陶瓷蓄热体的耐高温性、耐腐蚀性、显气孔率均高于国标要求，且明显优于对比例样品。因此，具有广阔的使用前景，通过引入了石墨烯，石墨烯可以进一步减少陶瓷材料的显气孔率，可以填充在氧化铝晶粒之间，并且石墨烯具有耐腐蚀性，可以提高金属蜂窝陶瓷蓄热体的蓄热性能，适合推广使用。
