A kind of pyrophosphate imidazole flame retardant and preparation method thereof |
| abstract |
The invention discloses a pyropolyphosphate imidazole flame retardant and a preparation method thereof. In the reaction device, phosphoric acid is mixed with imidazole or its derivatives to obtain imidazolium phosphate after the reaction. The imidazole pyrophosphate is prepared by dehydration reaction of imidazolium phosphate in an inert atmosphere or a high boiling point solvent, and the reaction temperature is 250°C-300°C. Imidazole pyrophosphate is a new type of phosphorus-nitrogen synergistic environment-friendly flame retardant. The imidazole ring is not only a nitrogen source provider, but its fused ring structure can effectively induce carbon formation and improve the flame retardant efficiency. The imidazole pyropolyphosphate is cost-effective, and the preparation method is simple and practical, and is suitable for industrial production. |
