Roof system adopting polyurethane foaming fire-resistant structure
The invention provides a roof system adopting a polyurethane foaming fireproof structure. The roof system is sequentially provided with a roof structure layer, a flame retardant layer, a polyurethane foaming waterproof heat preservation layer and a polymer cement waterproof mortar protection layer from bottom to top. The thickness of the flame-retardant layer is 5-20 mm, and the combustion performance grade is A or B1 grade; the thickness of the polyurethane foaming waterproof thermal insulation layer is 20-80mm, and the combustion performance grade is B2 grade; the thickness of the polymer cement waterproof mortar protection layer is 5-30 mm, and the combustion performance grade is A grade. Construction is extremely simple, the waterproof, fireproof and heat preservation effects are good, the flame-retardant (B1) and non-combustible (A) material is adopted to wrap the combustible (B2) material, the flame retardance of the roof system can be greatly improved, and the roof system is especially suitable for steel structure and wood structure roofs and is worthy of application and popularization.
本发明提供了一种采用聚氨酯发泡耐火构造的屋面系统，所述屋面系统从下往上依次设置有屋面结构层、阻燃层、聚氨酯发泡防水保温层以及聚合物水泥防水砂浆保护层；所述阻燃层的厚度为5～20mm，燃烧性能等级为A或B1级；所述聚氨酯发泡防水保温层的厚度为20～80mm，燃烧性能等级为B2级；所述聚合物水泥防水砂浆保护层的厚度为5～30mm，燃烧性能等级为A级。本发明施工极其简单，防水、防火和保温效果好，其采用难燃(B1)、不燃(A)性材料包覆可燃(B2)的材料，可大大提高屋面系统的阻燃性，尤其针对钢结构、木结构屋面，值得推广应用。
