随着我国轻型结构的发展,彩色钢板、铝板、石膏板、石棉板等各种轻型复合墙板得到了大量启用。建筑密封膏是轻型结构中不可缺少的配套材料。我国从六十年代到八十年代初,建筑物的接缝材料有了新的发展。除了生产常用的沥青系油膏及煤焦油聚氮乙烯胶泥塑料油膏外,还研制了几种用于内外墙、门窗、洗涮间的中、高档溶剂型与反应型密封膏。如氯丁橡胶、聚氨脂、聚硫橡胶及有机硅等。从国外建筑业的发展趋势看,密封材料的
With the development of China’s lightweight structure, various lightweight composite wallboards such as colored steel sheets, aluminum sheets, gypsum sheets, and asbestos sheets have been widely used. Building sealant is an indispensable supporting material in light structure. In China from the 1960s to the early 1980s, new joint developments in building materials have taken place. In addition to the commonly used asphalt-based ointment and coal tar NPE-plastic clay ointment, several medium-to-high-grade solvent-based and reactive sealing pastes have been developed for internal and external walls, doors and windows, and washing rooms. Such as neoprene, polyurethane, polysulfide rubber and silicone. From the development trend of foreign construction industry, the sealing material
