建筑结构胶粘剂是近30年开发与应用的一类新型化工材料,它是应用于胶接各类承受较大荷载构件的高强度胶种。五十年代初,美国新泽西州首先用环氧树脂建筑结构胶对公路进行修复;到六十年代,各发达国家已将其广泛用于公路铁路桥、机场跑道修补、水利工程及军事设施的加固;进入七十年代,建筑结构胶已大量用于各类构件、各类结构材料的胶接与补强。如美国加州圣弗南多地震时,
Building structural adhesives are a new class of chemical materials developed and applied in the past 30 years. They are used for bonding high-strength plastics that are subjected to heavy load components. In the early 1950s, New Jersey, USA, first used epoxy resin architectural adhesives to repair roads; by the 1960s, developed countries had widely used them for the reinforcement of highway and railway bridges, airport runways, water conservancy projects, and military facilities. In the 1970s, building structural adhesives have been used extensively to glue and reinforce various types of structural materials. When the earthquake in San Fernando, California,
