Phase change gypsum block and preparation method thereof
According to the phase change heat storage gypsum block and the preparation method thereof, based on 100 parts by weight of building gypsum, the phase change heat storage gypsum block comprises 7-9 parts by weight of organic phase change powder, 0.07-0.15 part by weight of a film-forming agent, 5 parts by weight of glass fiber and 60-70 parts by weight of water. The preparation method comprises the following steps: mixing expanded graphite and 12 to form organic phase change powder; pectin and a sodium alginate solution are used as film-forming agents, the phase change powder is subjected to micro-packaging, and micro-packaged organic phase change powder is formed; and mixing the micro-packaged organic phase change powder with building gypsum, a reinforcing agent and water to form slurry, pouring the slurry into a mold, and carrying out drying molding to form the phase change heat storage gypsum block. A microencapsulated organic phase change material with reliable performance is obtained through microencapsulation, and then the microencapsulated organic phase change material is added into a gypsum block to obtain the phase change heat storage gypsum block. The packaging method provided by the invention is simple and easy to implement, and the obtained phase change gypsum block has good heat storage and heat preservation capabilities and has mechanical strength meeting standard requirements.
一种相变储热石膏砌块及其制备方法，以建筑石膏质量为100重量份计，有机相变粉末占7~9重量份，成膜剂占0.07~0.15重量份，玻璃纤维占5重量份，水占60~70重量份。制备方法为，将膨胀石墨与十二混合，形成有机相变粉末；将果胶、海藻酸钠溶液作为成膜剂，对相变粉末进行微封装，形成微封装有机相变粉末；将所述微封装有机相变粉末与建筑石膏、增强剂、水混合形成料浆，倒入模具后干燥成型，形成所述相变储热石膏砌块。通过微封装得到了性能可靠的微封装有机相变材料，然后将其添加在石膏砌块中得到相变储热石膏砌块。本发明提供的封装方法简单易行，得到的相变石膏砌块具有良好的储热保温能力，并具有符合标准要求的机械强度。
