High-temperature-resistant and corrosion-resistant special thermal insulation material and preparation method thereof
The invention provides a high-temperature-resistant and corrosion-resistant special thermal insulation material and a preparation method thereof. The high-temperature-resistant and corrosion-resistant special thermal insulation material is prepared from, by mass, 50-80 parts of organic adhesive sol, 70-120 parts of powder and 20-30 parts of auxiliaries. The preparation method comprises the following steps: 1, dissolving a required amount of an organic binder in an organic solvent to prepare an organic binder sol; 2, stirring a required amount of powder and a required amount of organic binder sol to prepare a wet material, adding a required amount of an auxiliary agent while stirring, and uniformly stirring; step 3, the uniformly stirred wet material is put into a mold for compression molding, demolding is performed after drying initial setting and hardening are performed, the temperature is 120 DEG C or below in the drying process, and the time is 3-12 hours; and 4, demolding to obtain a molded material, and sintering the molded material at 300-600 DEG C to obtain a finished product for 3-8 hours. The prepared thermal insulation material has high temperature resistance and corrosion resistance, and can resist the high temperature of 950-1500 DEG C, so that the thermal insulation material can be applied to metal smelting and other high-temperature melt environments with corrosion and oxidation atmospheres.
本发明提供了一种抗高温及耐腐蚀的特种保温材料及其制备方法，按质量份数计为：有机粘合剂溶胶50份~80份、粉料70份~120份、助剂20份~30份。第一步，将所需量的有机粘结剂溶于有机溶剂中，制成所述有机粘结剂溶胶；第二步，将所需量的粉料和所需量的有机粘结剂溶胶搅拌制成湿料，在搅拌的同时加入所需量的助剂并搅拌均匀；第三步，将搅拌均匀的湿料放入模具中压制成型，进行干燥初凝及硬化后脱模，在干燥的过程中处于120℃以下、时间为3‑12小时；第四步，脱模后得到成型材料，然后成型材料300‑600℃温度下烧结成成品，烧结的时间为3‑8小时。本发明制得的保温材料具有耐高温和耐腐蚀的性能，其可耐950℃至1500℃的高温，使本发明的保温材料能够应用于金属冶炼等具有腐蚀及氧化氛围的高温熔体环境中。
