Abstract

The invention discloses second-order hot-mixed epoxy tack coat oil and application thereof. The oil comprises a resin component A and a curing component B, and the resin component A comprises bisphenol A epoxy resin NPEL128, non-bisphenol A epoxy resin, a diluent and a coupling agent. The curing agent component B comprises a high-temperature curing agent and a normal-temperature curing agent, wherein the ratio of the epoxy resin component A to the curing agent component B is (2: 3)-(3: 2). The second-order hot-mixed epoxy adhesive layer oil is high in bonding strength, excellent in flexibilityand good in waterproof performance, and can be widely applied to large-span steel bridge deck pavement as the second-order hot-mixed epoxy tack coat oil.

Description

technical field [0001] The invention relates to chemical materials and their uses, in particular to a second-stage hot-mix epoxy adhesive layer oil and its uses. Background technique [0002] At present, bridge construction has developed rapidly, and the wide application of new materials and new structures has made great progress in the construction technology of long-span bridges such as suspension bridges and cable-stayed bridges. However, steel bridge deck pavement technology is still a problem that has not been well resolved. [0003] The technology of paving epoxy asphalt concrete on steel box girder bridge deck is one of the world-class problems in bridge construction. The steel box girder bridge deck pavement epoxy asphalt concrete technology is different from the cement concrete bridge deck pavement. Due to the structural characteristics of the steel box girder bridge and the material properties of the steel plate, it determines Compared with the cement concrete br...
