Phase change concrete and preparation method thereof
The invention discloses phase change concrete and a preparation method thereof. The preparation method comprises the steps that a natural inorganic porous material serves as a carrier, a hydrated salt phase-change material is loaded, a hydrated salt-porous carrier compound is prepared, then the hydrated salt-porous carrier compound is wrapped with water-soluble silicon or water glass, a hydrogel-coated hydrated salt-porous material compound type phase-change energy storage material is prepared after dehydrating, and the hydrogel-coated hydrated salt-porous material compound type phase-change energy storage material is mixed with concrete to obtain the phase-change concrete. According to the phase-change concrete, the hydrated salt phase-change material is isolated from the concrete, the heat storage and release performance of the hydrated salt phase-change material is kept, and possible hydrated salt leakage and migration in the mixing process of the hydrated salt phase-change material and the concrete and the application process of the phase-change concrete are completely eradicated through multi-layer coating of hydrogel, so that the hydrated salt phase change energy storage material can be applied to concrete.
本发明公开了一种相变混凝土及其制备方法，本发明利用天然无机多孔材料作为载体，负载水合盐相变材料，制备水合盐‑多孔载体复合物，然后以水溶硅或水玻璃包裹水合盐‑多孔载体复合物，脱水后制备得到水凝胶包覆的水合盐‑多孔材料复合物型相变储能材料，所述水凝胶包覆的水合盐‑多孔材料复合物型相变储能材料与混凝土混合，得到相变混凝土。所述相变混凝土实现了水合盐相变材料与混凝土的隔离，保持了水合盐相变材料的储放热性能，而水凝胶多层包覆则杜绝了水合盐相变材料在与混凝土混合过程中及相变混凝土在应用过程中可能的水合盐泄漏和迁移，使得水合盐相变储能材料在混凝土中得以应用。
