Composite phase-change energy storage material, preparation method thereof, gypsum-based phase-change energy storage material and application of gypsum-based phase-change energy storage material
The invention provides a composite phase change energy storage material and a preparation method thereof, and a gypsum-based phase change energy storage material and application thereof. The composite phase change energy storage material provided by the invention comprises a porous carrier and silica sol-diatomite coating the surface of the porous carrier, a water-based phase change energy storage matrix material is adsorbed in pore channels of the porous carrier; the water-based phase change energy storage matrix material is a binary inorganic hydrated salt and a nucleating agent. A water-based phase change energy storage matrix material is adsorbed by a porous carrier material and then is coated by silica sol-diatomite, and the phase change energy storage matrix material is loaded by utilizing the high specific surface area, unique adsorbability and excellent thermal stability of the porous material, so that the problem of liquid phase flow of a solid-liquid phase change material is solved, and the problem of leakage of an organic phase change material is avoided. The compressive strength of the gypsum-based phase change energy storage material prepared from the composite phase change energy storage material reaches 20 MPa or above, the breaking strength is 6 MPa or above, and the gypsum-based phase change energy storage material is suitable for energy-saving use of building materials.
本发明提供了一种复合相变储能材料及其制备方法、石膏基相变储能材料及其应用。本发明提供的复合相变储能材料，包括多孔载体和包覆在所述多孔载体表面的硅溶胶‑硅藻土；所述多孔载体的孔道内吸附有水基相变储能基体材料；所述水基相变储能基体材料为二元无机水合盐和成核剂。本发明将水基相变储能基体材料经多孔载体材料吸附，然后经硅溶胶‑硅藻土包覆，利用多孔材料的高比表面积、独特吸附性和优异热稳定性，负载相变储能基体材料，解决固‑液相变材料液相流动问题，避免了有机相变材料泄露的问题。采用本发明所述复合相变储能材料制备的石膏基相变储能材料的抗压强度达到20MPa以上，抗折强度在6MPa以上，适用于建筑材料的节能使用。
