随着建筑技术的发展和建筑结构的改革,装配式混凝土和钢筋混凝土结构日益增多.各种予制混凝土构件之间会出现许多接缝,为了防止接缝的泄漏,就产生了嵌填这些接缝的建筑密封材料。建筑密封材料是用来嵌填建筑上设计的接缝,具有水密、气密和防尘等性能,是以聚合 With the development of building technology and the reform of building structures, the number of fabricated concrete and reinforced concrete structures has increased. Many types of joints have appeared between various precast concrete components. In order to prevent the leakage of joints, these joints have been embedded. Construction seal material. The building seal material is used to fill the seams designed on the building and has water-tight, air-tight and dust-proof properties.
