Phosphogypsum-based anorthite thermal insulation material and preparation method thereof
The invention relates to an ardealite-based anorthite thermal insulation material and a preparation method thereof. According to the technical scheme, the preparation method of the ardealite-based anorthite heat insulation material comprises the following steps: taking ardealite, fly ash, plastic clay and aluminum oxide as raw materials, adding a raw material pore-forming agent, adding a raw material sucrose aqueous solution, uniformly mixing, forming, drying, and preserving heat for 3-10 hours at 1200-1300 DEG C to obtain the ardealite-based anorthite heat insulation material. The ardealite-based anorthite heat insulation material is prepared. The preparation method of the pore-forming agent comprises the following steps: adding the inorganic sol into the pore-forming agent, uniformly stirring, dipping for 12-24 hours under the condition of normal pressure or 103-104 Pa, drying, crushing, and preserving heat for 5-6 hours at 500-550 DEG C to obtain the pore-forming agent. The method is low in production cost and short in production period; the product is small in volume density, good in compression strength and low in heat conductivity coefficient.
本发明涉及一种基于磷石膏的钙长石质隔热保温材料及其制备方法。其技术方案是：一种基于磷石膏的钙长石质隔热保温材料的制备方法，以磷石膏、粉煤灰、塑性黏土和氧化铝为原料，外加所述原料成孔剂，再外加所述原料蔗糖水溶液，混合均匀，成型，干燥，在1200~1300℃条件下保温3~10h，制得基于磷石膏的钙长石质隔热保温材料。所述成孔剂的制备方法为：向造孔剂中加入无机溶胶，搅拌均匀，在常压或103～104Pa条件下浸渍12～24h，烘干，粉碎，在500～550℃下保温5～6h，得到成孔剂。本发明生产成本低和生产周期短；其制品体积密度小、耐压强度良好和导热系数低。
