The invention relates to a preparation method of a phase-change foam concrete base material and a phase-change foam concrete block, the phase-change foam concrete base material comprises mixed powder of fly ash powder and coal gangue powder, 5%-10% by mass of an activator, 4% by mass of gypsum and 6% by mass of quicklime powder are added and uniformly stirred, and then the mixture is put into a mold for molding; performing ball milling in a ball mill to obtain pretreated raw materials; uniformly mixing and stirring 80%-87% of the pretreated raw material, 10%-17% of a shaped organic phase change heat storage material and 3%-5% of phase change fibers to obtain a phase change foam concrete base material; and uniformly stirring the phase-change foam concrete base material and cement according to the mass ratio of 1: 1-4: 1, and adding 0.5-1.0% of a water reducing agent to obtain the phase-change foam concrete structural body material. The phase-change foam concrete structural body material is prepared from the shaped organic phase-change heat storage material, the phase-change fibers, the fly ash powder, the coal gangue powder and the cement, and the lowest growth temperature (t is greater than or equal to 5 DEG C) of plants in a sunlight greenhouse can be fully ensured under the low temperature (about-10 DEG C) condition in winter while the structural performance of a wall body is ensured.
本发明涉及一种相变泡沫混凝土基料及相变泡沫混凝土砌块的制备方法，相变泡沫混凝土基包括粉煤灰粉末和煤矸石粉的混合粉料，按混合粉料质量的5％‑10％加入激发剂，4％的石膏，6％的生石灰粉搅拌均匀后，球磨机中球磨获得预处理原料；将预处理原料80％‑87％，定型有机相变蓄热材料10％‑17％，相变纤维3％‑5％混合搅拌均匀，获得相变泡沫混凝土基料；将相变泡沫混凝土基料与水泥质量比1：1‑4:1搅拌均匀加入0.5％‑1.0％的减水剂获得相变泡沫混凝土结构体材料。本发明通过定型有机相变蓄热材料、相变纤维及粉煤灰粉末和煤矸石粉末及水泥获得相变泡沫混凝土结构体材料，制备的保证墙体结构性能的同时，可以充分保证在冬季低温(‑10℃左右)情况下日光温室内植物的最低生长温度(t≥5℃)。
