Definitions
- the present invention relates to a flame retardant composition. More specifically, the present invention relates to a flame retardant composition which is excellent in processability and excellent in flame retardancy, moisture absorption resistance, heat resistance and extrusion workability when blended in a resin or the like.
- the mechanism of operation of the flame retardant drier is that the polyphosphoric acid phase generated on the resin surface during combustion and the carbonized layer formed as a result of dehydration of the resin become a film, thereby cutting off the supply of heat and oxygen to the resin during combustion. It is said that there is. It is particularly effective for resins that easily form a carbonized film, that is, are easily dehydrated. Conversely, when a resin that hardly forms a carbonized film due to dehydration is to be flame-retarded with phosphorus and a phosphorus compound, it is necessary to rely mainly on the polyphosphoric acid phase film. No. Therefore, it is difficult to form a carbonized film without increasing the amounts of phosphorus and phosphorus compounds. ⁇ Inspiration is born.
