Schiff base-coated ammonia polyphosphate for improving thermal and fire-retardant properties of unsaturated polyester
2024-07-08 08:41
Researchers found that the use of a Schiff base-coated ammonium polyphosphate (MAPP) significantly improves the thermal and fire-retardant properties of unsaturated polyester (UPR).
Despite extensive applications in modern industry, unsaturated polyester resin (UPR) suffers intrinsic flammability, presenting fire threats to both environment and properties. Existing environmentally benign flame retardants, in particular ammonium polyphosphate (APP), often show a limited efficiency in UPR. Herein, a Schiff base-coated ammonium polyphosphate (MAPP) was synthesized using APP, 1,2-bis(2-aminoethoxy)ethane, and terephthalaldehyde (TPA).
