Preparation method of high-strength thermal insulation material
The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of a high-strength thermal insulation material. The preparation method comprises the following steps: firstly, grinding and mixing vermiculite and montmorillonite, then putting the obtained mixture into an ethylene glycol solution after the grinding, mixing to prepare a dispersion, dropwise adding an alkali liquor into the dispersion, heating and stirring at high temperature to obtain an alkaline reaction solution, adding ramie into the alkaline reaction solution, carrying out oil bath heating treatment, adding acetic acid, mixing to obtain a to-be-reacted solution, adding ammonium persulfate for reaction, reacting at high temperature and high pressure to obtain aheat treatment product, performing suction filtration on the heat treatment product, washing, performing high-temperature sintering to prepare a modified thermal insulation agent, mixing the modifiedthermal insulation agent, stearic acid and other materials, performing hot pressing, freezing, soaking in acetone, and drying to obtain the high-strength thermal insulation material. The thermal insulation material prepared through the method is good in thermal insulation performance, good in mechanical strength and not prone to deformation and damage and has wide application prospects.
本发明属于建材制备技术领域，具体涉及一种高强度隔热材料的制备方法。本发明首先将蛭石、蒙脱土研磨混合，研磨后投入乙二醇溶液中混合制得分散液，随后将分散液中滴加碱液高温加热搅拌制得碱性反应液，再向碱性反应液中加入苎麻，油浴加热处理，加入乙酸混合制得待反应液，随后加入过硫酸铵反应，反应后高温高压反应制得热处理产物，再将热处理产物抽滤，洗涤，高温烧结制得改性隔热剂，最后将改性隔热剂、硬脂酸以及其它物料混合热压，冷冻，再用丙酮浸泡干燥制得高强度隔热材料，本发明制备的隔热材料，隔热性能较佳、力学强度较好，隔热材料不易变形、损坏，有广阔的应用前景。
