Mullite micro-nano pore heat insulation refractory material and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to a mullite micro-nano pore heat insulation refractory material and a preparation method thereof. The heat-insulating refractory material is mainly prepared from a base material, an additive and water, and the preparation process is green, environment-friendly, pollution-free, simple and easy to control. The main crystalline phase of the heat insulation refractory material is large-size needle-shaped and columnar mullite. The appearance of the product is white or faint yellow, the pore size distribution of pores is 0.006-200 [mu] m, the average pore size is 0.1-19 [mu] m, and the closed spherical micro-nano pore structure ensures that the product has better heat insulation performance under the conditions of lower volume density and high strength. By regulating and controlling the use amount of each raw material and the process, the finally prepared heat-insulating refractory material can meet the requirements of low heat conductivity and light weight, and also has better mechanical properties.
本发明属耐火材料技术领域，具体涉及一种莫来石质微纳孔绝隔热耐火材料及其制备方法。该隔热耐火材料主要由基础料、添加料和水制成，制备过程绿色环保无污染，简单易控。该绝隔热耐火材料的主晶相为大尺寸的针、柱状莫来石。制品外观呈白色或淡黄色，气孔孔径分布在0.006～200μm间，平均孔径0.1～19μm，封闭的球状微纳米尺寸气孔结构保证了制品在较低体积密度、高强度下较佳的绝隔热性能。通过调控各原料用量及工艺，可使最终制得的绝隔热耐火材料既满足了低导热和轻量化的需求，还具有较佳的力学性能。
