An eco-friendly flame retardant unsaturated polyester resin (UPR) material was prepared by combination organic magnesium hydroxide (OMH) and expandable graphite (EG). Different from direct addition of magnesium hydroxide (MH) in UPR matrix-like traditional method, OMH as a reactive monomer participates in the polycondensation reaction of UPR was more effective in improving the compatibility of flame retardant with matrix. Interestingly, the flame retardant UPR composites exhibited a more satisfactory flame retardant effect when a certain amount of 8 wt % EG was added into UPR/OMH matrix because of the synergistic effect between OMH and EG, resulted in the limited oxygen index from 21.7 to 28.5% and UL-94 test passed V-0 rating. Moreover, the peak heat release rate, total heat release, and smoke production rate of flame retardant UPR composites significantly reduced. The excellent flame retardancy was due to the formation of a dense and continuous carbon layer in the later stages of combustion.

“…However, as presented in Figure (b), as the amount of the flame‐retardant TGIC–AA–DOPO increased, the holes gradually disappeared, and a more continuous and compact char layer surface was formed. Such a structure is beneficial in isolating heat and hindering pyrolysis gas transport; thereby, it protects the underlying matrix from further combustion . The change in the char residue morphologies agreed well with the good flame retardancy of the TGIC–AA–DOPO/901‐VERs discussed in the sections on the LOI, UL‐94, and cone calorimetry tests.…”

In this study, a series of fire‐retardant vinyl ester resins (VERs) were obtained via the copolymerization of phosphorus–nitrogen‐containing acrylate [1,3,5‐triglycidyl isocyanurate (TGIC)–acrylic acid (AA)–9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO)] and the widely used vinyl ester resin 901 (901‐VER). The influences of the TGIC–AA–DOPO additive amount on 901‐VER were comprehensively evaluated via the measurement of the flame retardancy, thermal performance, and mechanical properties. In the case of 30 and 40% TGIC–AA–DOPO, the thermosets acquired limited oxygen index values of 30.8 and 31.7%, respectively, and reached vertical burning (UL‐94) ratings of V‐1 and V‐0, respectively. In addition, their peak heat‐release rates, average heat‐release rates, total heat release values, average effective heats of combustion, and total smoke productions decreased significantly. These results demonstrated the great progress of 901‐VER in fireproofing performance. More importantly, the flame‐retardant VER thermosets showed good thermal properties and castings, and glass‐fiber‐reinforced composites based on the developed fire‐retardant VERs possessed comparable tensile strength, flexural strength, and better tensile modulus comparing to those based on neat 901‐VER when the TGIC–AA–DOPO amount was no greater than 30%. From an integrated perspective, 901‐VER with 30% TGIC–AA–DOPO was the best desired. The excellent flame retardancy, thermal performance, and mechanical properties promise the as‐obtained VER important applicable values. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

Polymer materials are ubiquitous in daily life. While polymers are often convenient and helpful, their properties often obscure the fire hazards they may pose. Therefore, it is of great significance in terms of safety to study the flame retardant properties of polymers while still maintaining their optimal performance. Current literature shows that although traditional flame retardants can satisfy the requirements of polymer flame retardancy, due to increases in product requirements in industry, including requirements for durability, mechanical properties, and environmental friendliness, it is imperative to develop a new generation of flame retardants. In recent years, the preparation of modified two-dimensional nanomaterials as flame retardants has attracted wide attention in the field. Due to their unique layered structures, two-dimensional nanomaterials can generally improve the mechanical properties of polymers via uniform dispersion, and they can form effective physical barriers in a matrix to improve the thermal stability of polymers. For polymer applications in specialized fields, different two-dimensional nanomaterials have potential conductivity, high thermal conductivity, catalytic activity, and antiultraviolet abilities, which can meet the flame retardant requirements of polymers and allow their use in specific applications. In this review, the current research status of two-dimensional nanomaterials as flame retardants is discussed, as well as a mechanism of how they can be applied for reducing the flammability of polymers.
