摘要：A novel halogen-free flame-retardant system composed of dawsonite and magnesium hydroxide was used for flame-retarded ethylene vinyl acetate. The thermal and fire properties of flame-retarded ethylene vinyl acetate system were evaluated by thermagravimetric analysis (TGA), limiting oxygen index (LOI) and UL-94 test while the structure of combustion residue was characterized by scanning electron microscopy (SEM). The highest LOI value and the V-0 grade of the composites were attained by the 5wt% incorporation of dawsonite. These advancements are ascribed to the char stabilizer effect of fibrous-like combustion residue of dawsonite leading to increased strength of the residue.
