Preparation and properties of phase change energy storage composite with microcapsules and desulfurized gypsum

Funds: Scientific and Technological Breakthrough Foundation of Henan Province (212102310565); Key Scientific Research Projects of Universities in Henan Province (21B560008); State Key Laboratory of Solid Waste Resource Utilization and Energy Saving Building Materials (SWR-2020-007)
  • 摘要: 以相变微胶囊(MPCM)为储能基元与脱硫石膏复合,研究了MPCM对脱硫石膏基复合材料力学性能、热性能和热循环稳定性的影响规律。结果表明:MPCM的潜热储能作用可调节料浆的水化温升,起到缓凝作用,同时赋予复合材料储能调温功效;然而掺入MPCM对复合材料强度不利。MPCM掺量为50wt%时复合材料综合性能较好。此时,相变温度24.51℃,相变焓28.47 J·g−1,储热温峰和温峰出现时间较纯石膏分别降低和延迟了6.4℃、980 s,储热控温作用明显;导热系数0.451 W·(m·K)−1;28天抗压强度25.05 MPa;250次冷热循环质量损失率、相变温度变化率和相变焓变化率分别为0.67%、0.08%和2.3%,热循环稳定性良好。该复合材料力学性能、热性能和热循环稳定性良好,在建筑储能围护体系中应用前景广阔。
