Waste gypsum-based microcapsule phase change energy storage material and preparation method thereof
The invention discloses a waste gypsum-based microcapsule phase change energy storage material and a preparation method thereof, and belongs to the field of solid waste resource utilization and new materials. The preparation method comprises the following steps: compounding the pretreated waste gypsum and the phase-change ionic liquid, uniformly distributing the phase-change ionic liquid in waste gypsum slurry in a micro-capsule form under the synergistic effect of electrochemistry and microbubbles, and then forming and curing to obtain the waste gypsum-based micro-capsule phase-change energy storage material. The compressive strength of the waste gypsum-based microcapsule phase change energy storage material is 46-65 MPa, the breaking strength is 12-18 MPa, the waterproof coefficient is 0.86-0.92, the thermal conductivity is 0.512-0.612 W/(m.K), the latent heat of phase change is 167.34-201.11 J/g, and the phase change temperature is 27.5-30.5 DEG C. The problems that an existing phase change energy storage material prepared from waste gypsum is poor in energy storage effect, low in addition amount and poor in waterproof performance and mechanical performance can be effectively solved.
本发明公开了一种废石膏基微囊相变储能材料及其制备方法，属于固体废弃物资源化利用和新材料领域。制备方法为：将预处理后的废石膏和相变离子液体复配，在电化学和微气泡的协同作用下使相变离子液体以微囊的形式均匀分布于废石膏浆体中，然后进行成型养护，得到废石膏基微囊相变储能材料。废石膏基微囊相变储能材料的抗压强度为46～65MPa、抗折强度为12～18MPa，防水系数0.86～0.92，导热率为0.512～0.612W/(m.K)，相变潜热为167.34～201.11J/g，相变温度为27.5～30.5℃，可有效解决现有废石膏制备相变储能材料的储能效果不佳、添加量低以及防水性能和机械性能差的问题。
