整体喷涂聚氨酯在严寒地区屋面保温体系中应用的研究

Study on the Application of Monolithic Spray Polyurethane in Roof Insulation System in Cold Region

通过优化屋面保温和防水的构造设计,认为喷涂硬泡聚氨酯(PUR)屋面体系可实现保温防水一体化,能够克服传统防水材料渗漏造成保温层保温性能降低等一系列弊病。在北方严寒地区应用,将会提高屋面体系防水性能,大大减少建筑热能的损失量,达到节能环保的效果,提升严寒地区建筑室内舒适度。

By optimizing the structural design of roof insulation and waterproofing, it is believed that spray-hardened polyurethane(PUR) roof systems can achieve this integration. It can overcome the disadvantage of the decrease in thermal insulation performance caused by the leakage of traditional waterproof materials. Applying to the cold areas in the north, it will improve the waterproof performance of the roofing system, greatly reduce the loss of thermal energy, achieve the effect of energy saving and environmental protection, and improve indoor comfort.
