Rare earth nano material modified ultra-light castable and preparation method thereof
The invention provides a rare earth nano material modified ultra-light castable and a preparation method thereof, the castable is prepared from the following raw materials by weight: 20-35 parts of hydrophobic perlite, 20-30 parts of CA70 aluminate cement, 5-15 parts of shale ceramsite, 5-10 parts of a nano rare earth material, 5-10 parts of fly ash, 3-6 parts of silica powder, and 0.5-1 part of sodium tripolyphosphate. 1 to 3 parts of sodium hexametaphosphate, 0.1 to 0.4 part of explosion-proof fiber, 0.2 to 0.5 part of a dispersant and 20 to 35 parts of water; wherein the hydrophobic perlite is obtained by treating perlite with a hydrophobic solution, so that the surface of the perlite has hydrophobic groups, and the hydrophobic solution contains a rod-like rare earth nano material. The castable prepared by the invention has extremely low volume density and thermal conductivity and also has sufficiently high mechanical properties, and the compressive strength of the castable can reach 8MPa.
本发明提供了一种稀土纳米材料改性超轻质浇注料及其制备方法，该浇注料由包括如下重量份数的原料制备得到：憎水珍珠岩20‑35份，CA70铝酸盐水泥20‑30份，页岩陶粒5‑15份，纳米级稀土材料5‑10份，粉煤灰5‑10份，硅微粉3‑6份，三聚磷酸钠0.5‑1份，六偏磷酸钠1‑3份，防爆纤维0.1‑0.4份，分散剂0.2‑0.5份，水20‑35份；其中，憎水珍珠岩为由憎水溶液处理珍珠岩后使其表面带有憎水基团，憎水溶液中含有棒状稀土纳米材料。本发明所制备的浇注料在拥有极低的体积密度和热导率的同时，也拥有足够高的力学性能，其抗压强度可达8MPa。
