High-temperature nano-plate and preparation method thereof
The invention discloses a high-temperature nano-plate and a preparation method thereof, and the high-temperature nano-plate is prepared from the following components in percentage by weight: 40-60% of light aluminum silicate particles, 35-45% of activated calcium carbonate or nano aluminum oxide, 5-15% of silicon dioxide sol or aluminum dihydrogen phosphate, 5-15% of silicon dioxide sol or aluminum dihydrogen phosphate, 5-15% of silicon dioxide sol or aluminum dihydrogen phosphate, 5-15% of silicon dioxide sol The preparation method comprises the following steps: adding water into aluminum dihydrogen phosphate or silicon dioxide sol to dilute the aluminum dihydrogen phosphate or silicon dioxide sol by one time or two times; preparing slurry with activated calcium carbonate or nano aluminum oxide; stirring with light aluminum silicate particles; and uniformly stirring, pressing and molding in a mold, and drying. On the premise that the designed working temperature is not exceeded, shrinkage is completely avoided, it can be guaranteed that no gap exists in the whole heat preservation layer all the time as long as no gap exists in the installation process, and the overall heat preservation performance is better; after entering the working state, the aluminum silicate fiber board can generate about 20% of sub-nano pores, and the heat conductivity coefficient is 20% or above smaller than that of an aluminum silicate fiber board entering the working state.
本发明公开了一种高温纳米板及其制备方法，该高温纳米板由以下百分比含量的组分制备而成：轻质硅酸铝颗粒40％‑60％、活性碳酸钙或纳米氧化铝35％‑45％、二氧化硅溶胶或磷酸二氢铝5％‑15％，该制备方法包括以下步骤：将磷酸二氢铝或二氧化硅溶胶添加水稀释一倍或两倍；与活性碳酸钙或纳米氧化铝配成浆体；和轻质硅酸铝颗粒一起搅拌；搅拌均匀后放到模具里压制成型并烘干。在不超过设计工作温度的前提下，完全不会收缩，只要安装时没有缝隙就可以保证整个保温层永远没有缝隙，整体保温性能更好；进入到工作状态以后，自身会产生20％左右的亚纳米气孔，导热系数比同样进入到工作状态的硅酸铝纤维板小20％以上。
