摘要
聚氨酯保温材料具有质轻、导热系数小、易与其他基材粘接等优点,是目前广泛应用的保温材料中性能最好的一种;且还具有很好的耐热性、抗老化能力,是一种理想的绿色建筑保温材料。聚氨酯保温对外墙保温饰面层裂缝、渗漏,屋面、外窗四周封堵不严渗漏等工程质量常见问题专项治理中,发挥了不可替代的作用。但由于其行业整体技术水平不高、对聚氨酯保温材料的认识误区,阻碍其在民用建筑节能方面的推广应用。
Polyurethane insulation materials are currently the best performance of insulation materials. Rigid polyurethane light weight,low thermal conductivity,good heat resistance,aging resistance,easy to bond with other substrates,droplet combustion does not produce excellent performance is ideal for green building materials.Polyurethane insulation layer on the surrounding wall insulation finish cracks,leaks,roof,exterior windows,such as plugging leaks strict engineering quality FAQs special treatment,and play an irreplaceable role. But because of the low level of the overall technical industry the misunderstanding of polyurethane insulation materials,hindering the popularization and application of energy-saving in construction.
