Abstract

The invention discloses a preparation method and application of hot-mixed epoxy tack coat oil for steel bridge deck pavement, .Epoxy resin comprises a resin component A and a curing component B. The resin component A comprises 100 parts of bisphenol A epoxy resin, 3-15 parts of a diluent and 1-5 parts of a coupling agent; the curing agent component B comprises 0-10 parts of a rubber toughening agent, 40-80 parts of a high-temperature curing agent, 30-60 parts of a phenolic curing agent and 0.5-4 parts of an antioxidant. The ratio of the epoxy resin component A to the curing agent component B is 1: 1. The preparation method of the special hot-mixed epoxy tack coat oil for the steel bridge deck is simple, the bonding strength is high, the flexibility is excellent, the waterproof performance is good, and the special hot-mixed epoxy tack coat oil can be widely applied to large-span steel bridge deck pavement, tunnel pavement and cement bridge deck pavement as the hot-mixed epoxy tack coat oil.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a method for preparing hot-mix epoxy adhesive layer oil for steel bridge deck pavement and its application. Background technique [0002] The four innovative concepts of cable-stayed bridges, composite beams, orthotropic slab-steel decks and prestressed concrete segmental construction methods have had a significant impact on bridge engineering in the world today. The orthotropic steel deck structure has the advantages of light component weight, Due to the advantages of excellent structural performance, transportation and erection, low cost and short construction period, most of the long-span bridge decks that have been built in the past or are currently being built use orthotropic steel decks. The main girders of long-span bridges that have been built in my country generally adopt steel box girder structures, such as Shanghai Yangpu Bridge, Nanjing Yangtze River...
