作為目前的保溫防水一體化新型建材，聚氨酯硬泡保溫材料在國內(nèi)建筑業(yè)的應(yīng)用尚處于初始階段。可喜的是，為加快建筑保溫材料的革新，促進聚氨酯硬泡在建筑領(lǐng)域的推廣應(yīng)用，建設(shè)部專門成立了“聚氨酯建筑應(yīng)用工作組”,以推進聚氨酯硬泡保溫防水材料在國內(nèi)建筑
As the only new building material of heat preservation and waterproof integration, the application of polyurethane rigid foam insulation material in domestic construction industry is still in the initial stage. Fortunately, in order to speed up the innovation of building thermal insulation materials and promote the popularization and application of rigid polyurethane foam in the field of building energy conservation, the Ministry of construction has specially set up a "polyurethane building energy saving application working group" to promote the polyurethane rigid foam thermal insulation and waterproof materials in domestic building energy conservation
