The invention relates to the technical field of refractory materials, and provides a lightweight high-aluminum heat-insulating refractory brick, which comprises the following components in parts by weight: 30-50 parts of high bauxite clinker, 50-60 parts of a binder, 1-3 parts of organic fibers, 0.1-0.2 part of a water reducing agent, 1.2-1.6 parts of a foaming agent and 10-15 parts of kyanite, wherein the binder comprises kaolin and phosphoric acid in a mass ratio of (10-12): 1. The invention further provides a preparation method of the lightweight high-aluminum heat-insulating refractory brick. By means of the technical scheme, the problems that in the prior art, a lightweight high-aluminum heat-insulating refractory brick is low in strength and short in service life are solved.
本发明涉及耐火材料技术领域，提出了一种轻质高铝隔热耐火砖，配料按照重量份包括以下组分：高铝矾土熟料30‑50份、粘结剂50‑60份、有机纤维1‑3份、减水剂0.1‑0.2份、发泡剂1.2‑1.6份、蓝晶石10‑15份，所述粘结剂包括高岭土、磷酸，质量比为(10‑12):1。本发明还提出一种轻质高铝隔热耐火砖的制备方法。通过上述技术方案，解决了现有技术中的轻质高铝隔热耐火砖强度低，寿命较短的问题。
