摘　　要：利用改性的膨润土吸附由十四酸(MA)和十六醇(HD)混合而成的共熔相变材料(PCM),制取了膨润土基复合相变材料。扩散-渗出圈法实验结果表明,等质量的相变材料与改性膨润土混合为最佳质量配比,无泄漏现象。把水泥、标准砂、膨润土基复合相变材料和水按一定的比例混合制备了储能墙板,储能墙板能有效降低墙板表面温度峰值。添加6%的相变材料墙板储能效果最好,高温段的平均温度比普通墙板降低了3.0℃。Composite phase change materials of Myristic acid （MA） and Hexadecanol （HD） combined with the modified bentonite are prepared. The diffusion-seeping circle test results show that the mixture of the equal phase change material （PCM） and modified bentonite is the best quality ratio, and no leakage of PCM is found. Energy storage wallboards are prepared with different contents of cement, normal sand, phase change materials and water. The experimental results show that the composite phase change materials can reduce the peak temper- ature of wallboard. When the content of the phase change material in wallboard is 6%, the regulating ability of the phase change wallboard is the best, and the average temperature of energy storage wallboard reduces 3.0 ℃, compared with the ordinary wallboard.
