Preparation method of calcium hexaluminate fire-resistant heat-insulating material
The invention relates to a production method of a calcium hexaluminate fire-resistant heat-insulating material. The production method comprises the following steps: preparing calcium hexaluminate basic slurry, preparing balance slurry, preparing a blank and preparing the calcium hexaluminate fire-resistant heat-insulating material. The preparation method comprises the following steps: proportionally adding an aluminum-containing substance, a calcium-containing substance, water and a stabilizer into a ball mill, grinding for 1-6 hours to prepare calcium hexaluminate basic slurry, adding a coagulant and a coagulant into the basic slurry, performing uniform stirring, mixing with a foaming agent to prepare balanced slurry, pouring into a mold, standing for solidification, performing demolding, preparing a blank, performing drying, and performing sintering to prepare the calcium hexaluminate refractory heat-insulating material. In the step of preparing the balance slurry, a coagulating agent and a coagulation accelerator are added into calcium hexaluminate basic slurry for stirring, a foaming agent is mixed to prepare the balance slurry, solidification forming and demolding are accelerated, and compared with the prior art, the method has the advantages that raw materials are easy to obtain, the product cost is low, performance is stable, the process is simple, environmental pollution is avoided, and the solidification speed is high; and batch production can be carried out.
