Several Common Flame Retardants and Their Flame Retardant Principle

1. Halogen flame retardant: This is the most commonly used flame retardant at present. Its flame retardant principle is that halogen-containing flame retardant generates halogen-hydrogen acid when exposed to fire. This is a non-combustible gas with a large proportion. Around the burning material, it plays a role in isolating oxygen; in addition, halogen flame retardants also have the effect of capturing OH roots. 2. Phosphorus (boron)-containing flame retardant: Phosphorus (boron)-containing flame retardant mainly forms a non-combustible liquid film of phosphorus (boron) acid during combustion, and its boiling point can reach 300°C; At the same time, phosphoric acid further generates metaphosphoric acid, which is a very stable solid-phase polymer, covering the combustible, and covering the liquid phase and solid phase.
