3D printing phase change aggregate as well as preparation and application thereof
The invention discloses a 3D printing phase change aggregate as well as preparation and application thereof. The phase change aggregate is prepared by adopting a 3D printing hollow shell and filling the hollow shell with a solid-liquid phase change material through a vacuum impregnation method, after the phase change material is cured, an injection hole is packaged with a sealant, and the phase change material is applied to concrete to prepare phase change concrete. The 3D printing phase change aggregate is high in strength and extremely good in packaging performance, the phase change material cannot leak before concrete is structurally damaged, the toughness of the concrete can be effectively improved based on the mechanical property characteristics of the resin material, the prepared phase change concrete can effectively improve the temperature adjustment and heat preservation performance of the concrete, and the 3D printing phase change aggregate has the characteristics of high energy storage density, and high latent heat and stable temperature in the phase change energy storage process, can realize re-reasonable distribution of energy supply and demand in time and space, and improves the energy use efficiency.
本发明公开了一种3D打印相变骨料、制备及应用，相变骨料采用3D打印的中空壳体并在中空壳体通过真空浸渍法装满固液相变材料，待相变材料固化后用密封胶封装注入孔制成，将该相变材料应用在混凝土中制备得到相变混凝土。本发明的3D打印相变骨料强度高，封装性极好，在混凝土发生结构破坏前，相变材料不会发生泄露，并且基于树脂材料本身的力学性能特点能有效提高混凝土韧性，制备的相变混凝土可以有效的提高混凝土调温保温性能，具有储能密度大，潜热高，相变储能过程温度稳定的特点，可以实现能量供应与需求在时间和空间上的重新合理分配，提高能源使用效率。
