Summary: A phosphorus-containing melamine cyanurate derivative (P-MCA) flame retardant was synthesized to enhance the fire resistance and mechanical properties of epoxy resin (EP). The EP composite with 5 wt% P-MCA exhibited improved fire resistance, achieving a higher oxygen index and fire rating, as well as reduced peak heat release rate and smoke production rate.

Summary: Poly(triazine-phosphamide) BPGA consisting of benzenemelamine and phenyl phosphonic dichloride was synthesized and characterized. The combination of BPGA and melamine cyanurate (MCA) showed synergistic flame-retardant properties in PA6, improving flame retardancy, self-extinguishing property, and char residue. The interactions between BPGA and MCA resulted in the formation of thermally stable residues and quenching of free-radical chain reactions, contributing to gas-phase flame inhibition.

Summary: In this study, hydroxylated melamine (MOH) was synthesized and used as a charring and blowing agent in combination with ammonium polyphosphate (APP) to develop an intumescent flame retardant for epoxy resin. The resulting APP/MOH system significantly improved the flame retardancy of epoxy resin, achieving a LOI value of 32.5% and reaching UL 94 V-0 standards. Compared to other flame retardant systems, such as APP/PER, the APP/MOH system exhibited lower peak heat release rate and peak smoke production rate.

Summary: In this study, a unique mono-component intumescent flame retardant PPy-MAPP was synthesized and applied to epoxy resin to obtain flame-retarded EP composites. The results demonstrate that PPy-MAPP greatly improves the flame retardancy and smoke suppression properties of EP. The mechanical test shows that PPy-MAPP has a minimal negative effect on the tensile strength and elastic modulus of epoxy resin.

Summary: In the plastic industry, recycling waste plastic to produce flame retardant PET helps save energy and reduce emissions. The effects of different additives (MCA, ADP, Kaol) on the flame retardant properties, combustion behavior, thermal degradation behaviors, and mechanical properties of R-PET composites were studied. The results showed that ADP had the best flame retardant effect, and Kaol improved both the flame retardant and mechanical properties of the composites.

Summary: The novel 2D supermolecule MAP, synthesized from MA and STMP, enhances the flame retardancy and improves the mechanical and dielectric properties of EP. The uniform dispersion of MAP in the EP matrix leads to improved thermal stability and significant enhancements in mechanical and dielectric properties of the EP-MAP composite.

Summary: To obtain flame-retardant epoxy resin (FREP) with excellent comprehensive properties, a multielement flame retardant SVPM was synthesized. The effects of SVPM on the thermal stability, heat resistance, mechanical behavior, and flame retardancy of EP were systematically investigated, and the flame-retardant mechanism of SVPM was explored. SVPM achieved a V-0 rating of vertical combustion and a high limiting oxygen index (LOI) value of 31.1% with only 0.12 wt% phosphorus content. Additionally, SVPM reduced smoke and heat release, and improved the mechanical properties of EP, including a 26.23% increase in tensile strength and a 16.67% increase in flexural strength. The flame-retardant mechanism involved the quenching of active free radicals and reduction of combustible volatiles by SVPM.
