Abstract

The invention discloses a building structure adhesive suitable for underwater construction. The component A comprises the following raw materials in parts by weight: 60-80 parts of epoxy resin, 5-10 parts of active diluent, 5-10 parts of toughening agent, 1-2 parts of coupling agent, 50-200 parts of filler, 1-4 parts of thixotropic agent and 1-4 parts of wetting dispersant. The second component Bcomprises the following raw materials in parts by weight: 100 parts of phenolic amine curing agent, 50-200 parts of active filler, 1-4 parts of thixotropic agent and 1-4 parts of wetting dispersant. The raw materials used in the building structure adhesive suitable for underwater construction are all highly hydrophobic raw materials, The structure adhesive has good underwater construction performance, can be insoluble, not float and not shrink in underwater construction, can be easily adhered and coated, leveled and adhered on the bonding surface, and can be applied to the bonding of underwater environment building structure. Its underwater bonding strength is high, and its mechanical properties and moisture-heat aging properties conform to the national standard GB50367-2013, GB50550-2010,GB50728-2011 requirements.

Description

technical field [0001] The invention relates to the technical field of building structure reinforcement adhesives, in particular to a building structure adhesive suitable for underwater construction. Background technique [0002] Building structure reinforcement adhesive is a kind of construction adhesive with polymer synthetic material as the main component. It has the characteristics of great cohesion and high bonding strength after curing. It is widely used in building reinforcement and reinforcement, high-rise building seismic reconstruction, road repair, In bridge reinforcement and other fields, the actual construction conditions of building structure reinforcement projects are complex, and many building structure reinforcement projects are completed underwater. The national authorities have promulgated specifications for the design, construction and material safety of building reinforcement, namely "Code for Design of Concrete Structure Reinforcement" (GB50367-2013), "...
