Abstract:

To solve the problems in the flammability of polyamide 6 (PA6) and the toxicity of halogen flame retardant modification, the combustion and flame⁃retardant mechanisms for PA6 were introduced. The research progress in the halogen⁃free flame⁃retardant modification of PA6 in recent years was reviewed, which included organic⁃flame⁃retardant modification (phosphorus⁃flame⁃retardant modification, nitrogen⁃flame⁃retardant modification, silicon⁃flame⁃retardant modification), inorganic⁃metals⁃flame⁃retardant modification, nano⁃flame⁃retardant modification, and halogen⁃free synergistic⁃flame⁃retardant modification. The future development prospect of halogen⁃free flame⁃retardant modification for PA6 was proposed.

Key words: polyamide 6, modification, flame retardancy
