Bio-based phase change temperature control cement mortar and preparation method thereof
The invention discloses bio-based phase-change temperature-control cement mortar and a preparation method thereof.The preparation method comprises the steps that fatty acid and fatty alcohol serve as phase-change materials, a multi-element phase-change material is obtained by adjusting the proportion and stirring and mixing, silica gel waste is prepared into silicon dioxide capable of loading the phase-change material through a sol-gel method, and the cement mortar is prepared into the bio-based phase-change temperature-control cement mortar. And then the multi-element phase change material is impregnated and packaged into silicon dioxide by a vacuum impregnation method, so that the environment-friendly composite phase change energy storage material is formed through combination of the bio-based phase change material and the silica gel waste. Then the composite phase-change energy storage material and cement mortar are mixed in proportion, so that the bio-based phase-change temperature-control cement mortar applied to buildings is formed, and the bio-based phase-change temperature-control cement mortar has phase-change temperature controllability and stability, is simple in preparation process and convenient to package and produce, improves the production efficiency, reduces the cost and the time loss, and is suitable for industrial production. And the material is a green and environment-friendly material.
本发明公开了一种生物基相变控温水泥砂浆及其制备方法，本发明以脂肪酸、脂肪醇作为相变材料，经过调节比例、搅拌混合得到多元相变材料，再通过溶胶凝胶法，将硅胶废料制备成可负载相变材料的二氧化硅，然后再通过真空浸渍法将多元相变材料浸渍封装到二氧化硅当中，从而通过生物基相变材料与硅胶废料的结合，形成绿色环保的复合相变储能材料。随后再将复合相变储能材料与水泥砂浆按比例进行混合，从而形成一种应用于建筑中的一种生物基相变控温水泥砂浆，其具有相变温度可调控性，稳定性，制备过程简单，便于封装和生产，提高了生产效率，降低了成本和时间损耗，更是一种绿色环保的材料。
