Activated sepiolite powder thermal insulation material and preparation method thereof
The invention relates to the technical field of sepiolite powder thermal insulation materials, and particularly discloses an activated sepiolite powder thermal insulation material and a preparation method thereof. The preparation method comprises the following steps: S1, adding sepiolite powder into an ethanol aqueous solution, adjusting the pH value, adding a starch aqueous solution, adding sodium trimetaphosphate, stirring, adding 3-aminopropyltrimethoxysilane, stirring, and filtering to obtain grafted sepiolite powder; s2, adding the grafted sepiolite powder into an organic solvent, adding ethyl acrylate, performing stirring treatment, adding diethylenetriamine, performing stirring treatment, adding 2-methacryloyloxyethyl phosphorylcholine, performing stirring treatment, filtering, washing and drying to obtain the activated sepiolite powder thermal insulation material. According to the activated sepiolite powder thermal insulation material obtained by the preparation method, grafting is performed on the surface, through mutual cooperation, the length and the number of surface branch chains are increased, and the using effect of the sepiolite powder in thermal insulation cement mortar is improved.
本申请涉及海泡石粉隔热材料技术领域，具体公开了一种活化海泡石粉隔热材料及其制备方法。制备方法包括如下步骤：S1、在乙醇水溶液中加入海泡石粉，调节pH值，加入淀粉水溶液，加入三偏磷酸钠，搅拌处理，加入3‑氨丙基三甲氧基硅烷，搅拌处理，过滤，获得接枝海泡石粉；S2、在有机溶剂中加入接枝海泡石粉，加入丙烯酸乙酯，搅拌处理，加入二乙烯三胺，搅拌处理，加入2‑甲基丙烯酰氧乙基磷酸胆碱，搅拌处理，过滤，洗涤，烘干，获得活化海泡石粉隔热材料。该制备方法获得的活化海泡石粉隔热材料，在表面进行接枝，并通过其相互配合，增加表面支链长度和支链数量，提高海泡石粉于隔热水泥砂浆的使用效果。
