ABSTRACT Rigid polyurethane foam (RPUF) has found extensive applications in various industries. However, its inherent flammability significantly constrained the further development of this composite material. This study focuses on enhancing flame retardancy RPUF through synthesis barium phytate (PABA) and successful fabrication co‐modified with PABA/zinc borate (ZB) using a one‐step method. The thermal stability, retardancy, smoke suppression properties modified were systematically investigated thermogravimetric analysis, cone calorimetry, density testing. results demonstrated that RPUF‐PABA7.5/ZB7.5 (containing 7.5 wt% PABA ZB) exhibited superior retardant, performance. Specifically, compared RPUF‐PABA15 (15 PABA), 1.1% increase limiting oxygen index (LOI). Moreover, peak heat release rate (PHRR) total (THR) reduced by 17.16% 19.28%, respectively, accompanied 5.41% decrease (Ds) 3.86% light transmission rate. also showed significant improvement mechanical properties, to RPUF‐PABA15. These findings provided valuable insights for future research modification flame‐retardant enhancement.

ABSTRACT The castor oil (CTO)‐based modified rigid polyurethane (RPUF) was successfully prepared by adding CTO to modify the polyols. experimental results showed that RPUF‐CTO9 (accompanied 10 wt% CTO) exhibited excellent thermal stability and flame retardancy in series samples, compared with original RPUF, pyrolysis temperature increased 8.67°C, activation energy (E) 16.57 kJ/mol, peak heat release rate (HRR) decreased 20.82 kW/m 2 , total (THR) 35.09%, smoke density (Ds) 10.67. In addition, had insulation properties, variations ranging from 5.8°C (during cooling) 1.5°C heating) less than respectively. Furthermore, also excelled terms of mechanical highest compressive strength (0.02 MPa) absorption efficiency (34%). current study important for wide application multifunctional foams.
