摘　　要：本文介绍了一般阻燃剂主要通过吸热冷却、气相稀释、形成隔热层和终止自由基链反应等途径,来实现对材料的阻燃。同时也相应的阐述了无机阻燃剂、有机阻燃剂以及膨胀型阻燃剂的阻燃特性及机理。The paper introduced that combustion of polymer materials was retarded by an endothermic and cooling process,a gas phase diluted,forming heat insulation layer and termination of free radical chain reaction when flame retardant was added into polymer materials.The mechanism of flame retardants was review too,including inorganic flame retardant,organic flame retardant and intumescent flame retardant.
