摘　　要：建筑围护结构相变材料有效提高室内保温性能,研究其最佳制备方式及对供暖的影响可为工程人员提供理论依据。优选了建筑维护结构材料的配比、载体吸附工艺、封装方式,分析了材料调温性能及隔热性能对室内供暖设计的影响。结果表明,月桂酸、硬脂酸和棕榈酸的质量配比为65.9:10.5:23.6。随着吸附温度和吸附时间的升高,可膨胀石墨的容留率先升高后降低,最佳吸附温度为55℃,最佳吸附时间为50min,推荐真石漆乳液-水泥粉胶粘封装。相比普通水泥砂浆,相变水泥砂浆在受热后中心最高温度明显降低,相变水泥砂浆墙体内侧温度明显更低,达到最高温度所需的时间延长,良好的调温能力和隔热性能有效改善了建筑围护结构的蓄热量和传热量,供暖系统补充供热量降低。Phase change materials for building envelope structures effectively improve indoor insulation performance,and studying their optimal preparation method and its impact on heating can provide theoretical basis for engineering personnel.The proportion of building maintenance structural materials,carrier adsorption process,and packaging method were optimized,and the impact of material temperature regulation and insulation performance on indoor heating design was analyzed.The results showed that the mass ratio of lauric acid,stearic acid,and palmitic acid was 65.9:10.5:23.6.With the increase of adsorption temperature and time,the tolerance of expandable graphite increases first and then decreases.The optimal adsorption temperature is 55℃,and the optimal adsorption time is 50min.It is recommended that the lotion cement powder adhesive packaging of stone like paint be used.Compared to ordinary cement mortar,the maximum central temperature of phase change cement mortar significantly decreases after being heated,and the temperature inside the wall of phase change cement mortar is significantly lower.The time required to reach the maximum temperature is extended,and the good temperature regulation ability and insulation performance effectively improve the heat storage and transfer capacity of the building enclosure structure.The supplementary heating capacity of the heating system is reduced.
