In building reinforcement projects, we often hear several common reinforcement methods, such as planting bars, bonded steel, carbon fiber, etc. These reinforcement methods use specific structural adhesives in construction, taking the popular epoxy resin structural adhesive as an example.
What is epoxy resin? Epoxy resin is a kind of polymer with the molecular formula (C11H12O3)n, which refers to the general name of a polymer containing more than two epoxy groups in the molecule. It is the condensation product of epichlorohydrin and bisphenol A or polyol. Due to the chemical activity of the epoxy group, various compounds containing active hydrogen can be used to ring-open, solidify and cross-link to form a network structure. It is a thermosetting resin.
Do you know what epoxy resin is and what is epoxy resin structural adhesive?
Epoxy structural adhesive is a solvent-free, liquid epoxy resin adhesive that cures at room temperature or by heating. After curing, the layer system is equal to hardness and can withstand strong impact and vibration. The layer has good mechanical properties and good electrical insulation, and can withstand temperature changes and deflection tearing stress. It is non-corrosive and has good adhesion, temperature resistance and oil resistance to metals, ceramics, vulcanized rubber, fiberglass products, carbon fiber products, etc.
Epoxy resin structural adhesive curing principle:
Epoxy resin structural adhesive is a chemical reaction between the curing agent and the epoxy resin to form a three-dimensional network polymer, which wraps the composite aggregate in the network. Makes linear resin a tough solid adhesive.
The above is the curing principle and process of epoxy resin structural adhesive introduced by the editor. If you want to know more about epoxy resin structural adhesive, you can consult Kain Industrial Additive epoxy reinforcement adhesive, steel adhesive, carbon fiber adhesive, etc.
