Abstract:

In recent years, some halogen-based flame retardants have been gradually eliminated out for consideration of the environment, and phosphorus-containing flame retardants have received extensive attention as substitutes for halogen-based flame retardants. However, efficient phosphorus-based flame retardants usually produce more smoke while improving flame retardancy, therefore, they need to be used in combination with synergists. This paper introduced the flame-retardant mechanism of phosphorus-containing flame retardants in epoxy resin. The latest research progress of synergists, including inorganic, organic, and organic-inorganic hybrid synergistic agents, with phosphorus-based flame retardants in epoxy resin was summarized. We look forward to the future development trend of the synergistic system of phosphorus-containing flame retardants in epoxy resin.
