1.3 Chemical Properties

BDMA is highly alkaline and nucleophilic and can react with a variety of compounds. In bridge construction, BDMA is mainly used as a curing agent for epoxy resins, which can significantly improve the mechanical properties and chemical resistance of the resin.

2. Application of BDMA in Bridge Construction

2.1 Epoxy resin curing agent

Epoxy resin is a commonly used adhesive and coating in bridge construction, and its performance directly affects the structural stability of the bridge. As a curing agent for epoxy resin, BDMA can accelerate the curing process of the resin and improve its mechanical strength and durability.

2.1.1 Curing mechanism

BDMA forms a crosslinking network structure by opening the ring with the epoxy groups in the epoxy resin. This process not only improves the hardness of the resin, but also enhances its impact resistance and chemical resistance.

2.1.2 Application Example

On large bridgesAmong the steel structures and concrete structures, epoxy resin coatings are widely used for corrosion resistance and waterproofing. As a curing agent, BDMA can ensure the long-term stability of the coating in harsh environments.
