Abstract

Abstract: Global regulations restrict the use of halogenated flame retardants due to their harmful gas emissions upon combustion. This review categorizes four types of halogen-free flame retardants: phosphorus-based, silicon-based, inorganic hydroxides, and intumescent systems. AHP demonstrates high flame retardancy but faces migration and toxicity issues; DOPO derivatives synergize with APP to enhance epoxy resin performance, though chlorinated phosphates exhibit neurotoxicity. SiO2@DPP and POSS are applied to polycarbonate and epoxy resins respectively, requiring combination with other flame retardants. ATH and MH blends reduce additive requirements but impair mechanical properties; APP synergistic systems improve the oxygen index of unsaturated polyester. DNA offers flame retardancy but relies on phosphorus-containing components with environmental risks. In the home appliance industry, halogen-free flame retardants are widely used in critical components like circuit boards and external casings to meet safety and environmental standards. Future research focuses on nanocomposites, bio-based materials, and intelligent design to achieve efficient and eco-friendly flame retardancy goals.

Key words: Polymer material, Halogen-free flame retardant, Oxygen index
