Fabrication of Flame-Retardant Ammonium Polyphosphate Modified Phytic Acid-Based Rigid Polyurethane Foam with Enhanced Mechanical Properties

Polymers, Год журнала: 2024, Номер 16(15), С. 2229 - 2229

Опубликована: Авг. 5, 2024

Ammonium polyphosphate (APP) and self-made nickel phytate (PANi) were used as modified materials to prepare green biomass rigid polyurethane foam (RPUF). The flame retardancy, thermal stability, smoke toxicity mechanical properties of the RPUF investigated by limiting oxygen index (LOI), a cone calorimetry (CONE) test, thermogravimetric analysis compression test. results showed that with 10 wt% APP (PANi/APP10) had highest LOI 26.5%. Its peak heat release rate (PHRR) total (THR) reduced 29.64% 24.05% compared PANi/APP0 without APP. And its production (SPR) (TSR) decreased 33.14% 19.88%, respectively. Compared pure RPUF, compressive strength PANi/APP10 was increased 50%, mainly because itself an ultra-fine powder, which better compatible matrix improved hardness material. synergistic effect gas phase condensed mechanism could effectively improve flame-retardant effect. current research provided new strategy for preparation low-toxicity RPUF.

Dual Flame-Retardant and Curing-Agent Effects of Phytic Acid–Guanazole as an Additive in Fire-Protective Coatings for Wood

Polymers, Год журнала: 2025, Номер 17(9), С. 1169 - 1169

Опубликована: Апрель 25, 2025

Recent research has focused on developing environmentally friendly flame-retardant coatings to improve the fire resistance of wood. In this study, phytic acid–guanazole (PG), a dual-functional compound synthesized through an ionic reaction between acid and guanazole, was added KH550-modified urea–formaldehyde resin (KUF) as both curing agent flame retardant. The −PO43− groups from act source accelerate char formation during combustion, while −NH2 introduced by guanazole release non-combustible gases dilute oxygen in air, synergistically enhancing retardancy. Additionally, hygroscopic absorb free water resin, reducing temperature accelerating coating solidification. KH550 coupling improves compatibility KUF PG introducing silicon, which forms SiO2 combustion strengthen layer further enhance resistance. Evaluations showed that outperforms conventional tannic (TA) efficiency Comprehensive analyses, including Differential Scanning Calorimetry (DSC), Limiting Oxygen Index (LOI), vertical tests, cone calorimetry, confirmed PG’s dual functionality. Electron Microscope (SEM) Raman spectroscopy revealed PG-modified form denser post-combustion layers, directly linked improved As multifunctional additive, eliminates need for separate agents utilizes bio-based acid, offering cost-effective sustainable advantages industrial applications.

Preparation of ABD‐@MMT Nano‐Flame Retardant Toward Fire‐Safety and Stable Mechanical Properties for Aramid‐Reinforced Epoxy Resin Composites

Journal of Applied Polymer Science, Год журнала: 2024, Номер 142(11)

ABSTRACT The mismatch of flame retardancy and mechanical properties is still a challenge for developing high‐performance epoxy resin (EP) its aramid fiber (AF) composite. In this study, bi‐DOPO compound (ABD) was prepared by reacting DOPO with acrolein, Na‐MMT modified octadecyltrimethylammonium chloride to prepare organic MMT(@MMT), finally, ABD‐@MMT nano‐flame retardant using ABD intercalate @MMT solve problem. After introducing into AF/EP composites, it exhibited good thermal stability, excellent retardancy, enhanced properties. intercalation exfoliation the layer within EP matrix indicated uniform dispersion retardant. Especially sample 3%ABD‐@MMT/AF/EP limiting oxygen index (LOI) value increased from 23.8% 34.7% accompanied V‐0 rating in UL‐94 test. Scanning electron microscopy (SEM) analysis residual carbon postcone calorimetry test degree graphitization after muffle calcination supported superior nanocompounds. Furthermore, tensile strength composites measured at 38.3 MPa, representing an 8.5% increase compared 3%ABD/AF/EP, only decreased 7% pure composites. incorporation improved both burning behavior composite, reflecting reduced intensity, strength, impact strength. This study presents novel approach retardancy.
