Preparation method of low-density high-strength anorthite thermal insulation material for hydrogen metallurgy field
The invention relates to a preparation method of a low-density high-strength anorthite thermal insulation material for the field of hydrogen metallurgy, and belongs to the field of hydrogen metallurgy. According to the preparation method, kaolin fine powder, corundum particles, corundum fine powder, alumina micro powder, silica micro powder and a calcium source are adopted as raw materials, sawdust is adopted as a pore forming agent, pure calcium aluminate cement is adopted as a binding agent, FS 20 is adopted as a water reducing agent, and HVPV is adopted as a plasticizer. Adding an aqueous solution and carrying out mechanical pugging; after pugging is completed, the pug is evenly projected and filled in the whole mold, and after drying is completed, heat treatment is conducted to obtain the low-density and high-strength anorthite heat insulation material. The prepared light heat insulation material has the performance characteristics of light weight, high strength, easiness in processing and the like.
本发明涉及一种氢冶金领域用低密高强钙长石质隔热材料的制备方法，属于氢气冶金领域。涉及的一种氢冶金领域用低密高强钙长石质隔热材料的制备方法，低密高强钙长石质隔热材料采用高岭土细粉、刚玉颗粒、刚玉细粉、氧化铝微粉、二氧化硅微粉、钙源为原料，以锯末为造孔剂，以纯铝酸钙水泥为结合剂，以FS 20为减水剂，以HVPV为增塑剂，加入水溶液，进行机械练泥；练泥完成后将泥料均匀投射填充在整个模具内，干燥完成后进行热处理得到低密高强钙长石质隔热材料。本发明制备的轻质隔热材料兼具轻质、高强、易加工等性能特点。
