摘　　要：为降低建筑能耗,试验以石蜡为相变材料,与膨胀石墨相结合制备一种复合相变材料的BIPV光伏建筑材料并研究其性能。试验结果表明,在水泥中掺入复合相变材料,会降低其力学性能,但可以提高相变温度T_(peak)和相变潜热ΔH,使BIPV光伏建筑材料具备良好的相变储能效果;试验中最佳复合相变材料掺量为30%,制备的BIPV光伏建筑材料在保证一定抗压强度、抗折强度下,相变潜热ΔH达到28.7 kJ/kg,且热稳定性较好;在实际应用方面,以BIPV光伏建筑材料制备的相变储能地板具备的储能效果,可以起到保暖、节能等作用。In order to reduce building energy consumption and protect the environment,paraffin wwaxwas used as a phase change material and combined with expanded graphite to prepare a composite phase change material,and BIPV photovoltaic building materials were prepared and their properties were studied.The experimental results indicated that adding composite phase change materials to cement could reduce its mechanical properties,but increase the phase change temperature T_(peak)and latent heat of phase change ΔH,so that BIPV photovoltaic building materials had a good phase change energy storage effect.In this experiment,the optimal content of PA/EG composite phase change material was 30%,and the latent heat of phase change ΔH reached 28.7 kJ/kg under the condition of ensuring certain compressive strength and flexural strength,and the thermal stability was good.In practical applications,the phase change energy storage floor made of BIPV photovoltaic building materials had the energy storage effect,which can play a role in warmth preservation and energy conservation.
