Summary: This paper aims to develop and optimize flame-retardant coatings for naval applications. The study investigates the effect of adding magnesium hydroxide and aluminum hydroxide fillers in an acrylic carrier on the fire resistance of the coatings. The results show that the coatings based on aluminum and magnesium hydroxides exhibit favorable fire resistance, particularly for short times of exposure to direct flames.

Summary: The combination of magnesium hydroxides and graphene oxide effectively improved the fire retardancy of polypropylene, with significant reduction in peak heat release rate, total heat release, and smoke production rate. The synergistic effect between GO and Mg(OH)(2) created an optimized physical barrier, resulting in enhanced mechanical properties and fire-safety of the polymer material.

Summary: In this study, hydromagnesite was used to synthesize magnesium hydroxide as a flame retardant for EVA. The introduction of magnesium hydroxide significantly improved the flame retardant properties and smoke suppression of the composites. The incorporation of different concentrations of sodium hydroxide had limited effect on the mechanical properties of the composites.

Summary: The study of flame-retardant coatings has become interesting in the effort to improve fire safety in various structures. This research focuses on adding harmless hydroxides, magnesium hydroxide and aluminum hydroxide, to an acrylic polymer emulsion to decrease the negative effects of flame-retardant additives on the coatings. Flame exposure tests are conducted to verify the flame stability and thermal insulation of the investigated coatings.

Summary: A new method for preparing MH-based flame-retardant paper with high flame retardancy was developed by uniformly loading MH, BMC or their mixture onto cellulose fibers. The loaded materials endow the paper with excellent thermal stability, flame retardancy and fire safety, especially when loaded with a MH/BMC mixture. This study provides a new approach for preparing paper with high flame retardancy.

Summary: Efficient and hydrophobic modificated ammonium polyphosphate (M-APP) and charring agent (M-CA) were prepared using sol-gel method for the preparation of water-resistant and flame-retardant polypropylene (PP) composites. The results showed improved flame retardancy and reduced heat and smoke release in the PP composites. Additionally, the PP composite with M-APP/M-CA = 3:1 exhibited excellent water resistance even after soaking in 70 degrees water for 168 hours.

Summary: A new biobased flame retardant (MHPA) was synthesized by neutralizing magnesium hydroxide (MH) with phytic acid (PA). Adding MHPA to ethylene vinyl acetate (EVA) significantly improved the fire retardancy, smoke suppression, and mechanical properties of the composites. The combination of MHPA and MH exhibited excellent carbonization and expansion effects, contributing to the improved flame retardancy.

Summary: An environmentally friendly nanohybrid expandable graphite (nHEG) was successfully designed and synthesized for flame-retardant polypropylene (PP) composites, achieving UL-94 V0 rating. By introducing nano-SiO2 particles and expandable graphite, the enhanced flame retardancy was attributed to the formation of continuous and tight char residues.

Summary: In this study, an effective flame retardant consisting of nanoscale zinc oxide doped on the surface of hexagonal lamellar magnesium hydrate (ZO@MH) has been successfully synthesized. The modified ZO@MH shows improved interfacial interaction with the polypropylene (PP) matrix and reduced agglomeration. The resulting composite materials exhibit enhanced flame retardancy and smoke suppression properties, and also improve the strength of the PP matrix.

Summary: In this study, silicone rubber (SR) was added to high-density polyethylene/magnesium hydroxide (HDPE/MH) composites and electron beam irradiation was used to prepare flame retardant HDPE composites. The addition of SR improved the lubricity and interfacial compatibility of HDPE composites, and enhanced the continuity between MH and HDPE, leading to improved flame retardant properties.
