The invention relates to a geopolymer straw phase change building block and a preparation method and application thereof, and the geopolymer straw phase change building block comprises the following raw materials by weight: 25%-35% of straw powder shaped phase change heat storage material particles, 15%-25% of fly ash shaped organic phase change heat storage material, 10%-20% of fly ash, 10%-20% of metakaolin, 10%-15% of an alkali activator, and 0.1%-1.0% of a coupling agent. 0.9%-2.5% of a polymer cementing material and 9%-12% of water. The phase change wall suitable for the sunlight greenhouse is made of agricultural waste straw, leakage is not prone to occurring, packaging is stable, and when the phase change wall is applied to the sunlight greenhouse, the indoor minimum temperature can reach 12.5 or above when the outdoor minimum temperature can reach-33 DEG C or below.
本发明涉及一种地质聚合物秸秆相变砌块及其制备方法及应用,包括以下重量份原料：秸秆粉定型相变蓄热材料粒子25％‑35％，粉煤灰定型有机相变蓄热材料15％‑25％,粉煤灰10％‑20％，偏高岭土10％‑20％，碱激发剂10％‑15％，偶联剂0.1‑1.0％，聚合物胶凝材料0.9％‑2.5％，水9％‑12％。本发明利用农业废物秸秆制作满足日光温室适合的相变墙体，不易泄漏，封装稳定，本发明相变墙体应用在大棚日光温室，可以在室外最低气温可以达到‑33℃以下时，还能够实现室内最低位于12.5以上。
