密封材料是现代工业重要的配套材料,合理选用密封材料,不仅能解决建筑物的渗漏,延长建筑物的使用寿命,又能提高建筑物的绝热保温性能。七十年代国外建筑密封材料的产量连年大幅度增长,主要原因在于新型建筑物的发展,超高层建筑,大型框架挂板结构、玻璃幕墙、中空玻璃等建筑设计被广泛应用,这些新型建 Sealing materials are important supporting materials for modern industry. Reasonable selection of sealing materials can not only solve the leakage of buildings, prolong the service life of buildings, but also improve the thermal insulation performance of buildings. In the 1970s, the output of foreign construction seals increased significantly year-on-year, mainly due to the development of new types of buildings. High-rise buildings, large-scale frame plywood structures, glass curtain walls, hollow glass and other architectural designs were widely used. These new types of construction
