摘　　要：屋面保温隔热系统在建筑节能方面占据重要角色,因此对市场上常见的屋面保温隔热材料(聚氨酯、聚乙烯发泡板、聚丙烯蜂窝板、聚碳酸酯蜂窝板)进行调研,并根据规范标准设计了 4种耐候性试验条件。通过试验得出,4种保温材料的导热系数随着耐候性试验时间的增加而显著增大:聚丙烯蜂窝板在耐候性试验的性能最差,导热系数变化值在湿热老化和冻融循环试验下分别达到了 79.3%和39.9%;聚氨酯在高低温试验下的导热系数变化值为24.5%,在干湿循环试验下,导热系数变化值为33.4%。试验结果表明,上述4种材料均不适用于干湿较强的地区,并且,聚丙烯蜂窝板不适用于湿热和冻融地区,聚氨酯不宜用于高低温地区。Roof thermal insulation system played an important role in building energy saving, so the common roof thermal insulation materials ( polyurethane, polyethylene foam board, polypropylene honeycomb board, polycarbonate honeycomb board) on the market were investigated, and four weather resistance test conditions were designed according to the standard. The results showed that the thermal conductivity of four kinds of thermal insulation materials increased significantly with the increase of weathering test time: polypropylene honeycomb board performed the worst under weathering test, and the thermal conductivity of polypropylene honeycomb board reached 79. 3% and 39. 9% under wet-thermal aging and freeze-thaw cycle test, respectively;polyurethane had a thermal conductivity of 24. 5% under high and low temperature test, and the thermal conductivity system under dry?wet cycle test. The number change value was 33. 4%. The test results showed that the four materials were not suitable for dry and wet areas. In addition, polypropylene honeycomb boards were not suitable for hot and humid areas, and polyurethane was not suitable for high and low temperature areas.
