硬泡聚氨酯作为新型墙体保温材料之一,在欧美等发达国家应用较为普遍。硬泡聚氨酯拥有优异的保温隔热性能,具有防潮、防水、耐老化、耐高温等优点。同时,聚氨酯材料还有自身重量轻、切割精度和制成品表面平整度高,以及高温下不会产生有害气体等优点,是一种比较理想的墙体保温材料。近年来,在国家建筑节能管理部门和行业协会的大力推动下,通过产、学、研联合开发,已经推出多套适合于我国建筑国情的硬泡聚氨酯外墙外保温系统, Rigid polyurethane as a new type of wall insulation materials, and other developed countries in Europe and the United States more commonly used. Rigid polyurethane has excellent thermal insulation properties, with moisture, water, anti-aging, high temperature and other advantages. At the same time, polyurethane material also has its own light weight, cutting precision and finished product surface roughness, and high temperature does not produce harmful gases, etc., is an ideal wall insulation material. In recent years, with the vigorous promotion of national building energy-saving management departments and trade associations, a number of sets of rigid foam polyurethane exterior insulation systems suitable for China’s construction conditions have been launched through the joint development of production, study and research,
