Abstract A nanoscale hexagonal flake magnesium hydroxide (MH) flame retardant was prepared by a hydrothermal method using Tibetan microcrystalline magnesite as the raw material. The synthesized samples were characterized x-ray diffraction (XRD), field-emission scanning electron microscopy (FSEM), thermogravimetric analysis-differential calorimetry (TG-DSC), and laser particle size analysis. When subjected to treatment at 180 °C for duration of 8 h in solution containing 6 mol l −1 NaOH, with incorporation 4 wt% surfactant polyethylene glycol 2000 (PEG2000), MH, possessing an average 378.3 nm, successfully synthesized. study conducted examination thermal, mechanical, flame-retardant properties both EP EP/MH composites. results revealed that 9 MH led notable reduction peak heat release rate, total smoke production, mass loss rate composites 36%, 14.5%, 33.3% respectively, compared pure EP. Remarkably, tensile flexural strength composite exhibited minimal impact.

ABSTRACT To improve the flame‐retardancy of ethylene–vinyl acetate copolymer (EVM), magnesium hydroxide (MH) is often added to prepare composites. Generally, addition a large amount will reduce mechanical properties simultaneously both and flame‐retardant properties, we modified MH with chitosan (CS) its compatibility dispersion in EVM. Based on property CS dissolve acidic solutions precipitate alkaline solutions, employed coprecipitation method MH@CS filler . We studied effects flame retardancy The results show that imparts better tensile strength EVM/MH@CS was 143% EVM/MH, while elongation at break 110% for EVM/MH. Additionally, peak heat release rate (PHRR), total smoke production (TSP), generation harmful gases were significantly reduced EVM/MH@CS, char layer formed after combustion denser. At 40 wt% content, limiting oxygen index (LOI) reached 28.4%. This study presents feasible development EVM‐based materials high performance.

Nowadays, with the approaching carbon neutrality deadlines and implementation of zero-net emission policies, research development flame retardants are increasingly influenced by stringent regulations laws. In this context, natural inorganic materials have garnered significant attention as promising to enhance fire resistance polymer composites. These offer unique advantages, such being environmentally friendly, cost-effective, producing no emissions during preparation. Consequently, in recent years, there has been a rapid increase on mineral retardants. This review systematically introduces progress minerals epoxy resin, highlighting their ability provide exceptional resistance. Additionally, we categorize various chemical modification approaches for explore different mineral-based Furthermore, elucidate retardant mechanisms behind both modified systems. Beyond summarizing concluding current state research, also project future directions identify challenges
