The invention discloses heat storage and temperature regulation concrete and a preparation method thereof, and relates to the field of energy storage materials. When the heat storage and temperature regulation concrete is prepared, the phase-change energy-storage material is used for replacing aggregate, and then the carbon fibers and the calcium carbonate are added into the Portland cement; the phase change energy storage material is prepared by adsorbing nanocapsules by using porous ceramsite and then encapsulating by using calcium alginate, and the nanocapsules are prepared by using modified silicon dioxide as a hybrid wall material and n-octadecane as a core material; n-octadecane is used as the core material to prepare a nano microcapsule, and the phase change energy storage material can release heat more quickly by virtue of the cross-linked network of the hybrid wall material; pores among the encapsulated nanocapsules form a closed space so that the phase change energy storage material has relatively high thermal insulation performance; the carbon fibers and the phase change energy storage material form a stable cross-linked network so that the heat transfer effect and the impact resistance are enhanced.
本发明公开了一种蓄热调温混凝土及其制备方法，涉及蓄能材料领域。本发明在制备蓄热调温混凝土时，使用相变储能材料代替骨料，再在硅酸盐水泥中加入碳纤维和碳酸钙；相变储能材料是使用多孔陶粒吸附纳米胶囊，再利用海藻酸钙进行包封制得，纳米胶囊是利用改性二氧化硅作为杂化壁材、正十八烷为芯材制得；以正十八烷为芯材，制成的纳米微胶囊，借助杂化壁材的交联网络，使得相变储能材料更快放热；包封后纳米胶囊间的孔隙形成密闭空间，使得相变储能材料具有较高的保温性能；碳纤维与相变储能材料形成稳定的交联网络，增强热传递效果和抗冲击性。
