桥面覆层用弹性环氧胶粘剂的研究

Study on elastic epoxy adhesive for bridge deck overlay

在对桥面覆层用弹性环氧胶粘剂进行制备时,结合对相关稀释剂、增韧剂、固化剂的研究,从不同配方出发进行优化,最终获得性能良好的弹性环氧胶粘剂。结合拉伸测试发现:该桥面覆层用弹性环氧胶粘剂的拉伸强度、断裂伸长度和混凝土粘接强度等方面均表现不错,其综合性能优异,能够适用于桥面铺装工程。

When preparing the elastic epoxy adhesive for bridge deck cladding,combining with the research of related diluents,toughening agents and curing agents,the elastic epoxy adhesive with good performance was optimized from different formulations.Combined with the investigation of tensile test,it is found that the elastic epoxy adhesive used for bridge deck cladding has good tensile strength,elongation at break,and concrete bonding strength,and its comprehensive performance is excellent,which can be applied to bridge deck pavement engineering.
