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: Rigid polyurethane foam (RPUF) is a highly effective thermal insulation material, but its flammability poses a fire hazard. The large specific surface area of RPUF makes it prone to ignition and rapid fire spread when exposed to heat sources. A flame-retardant coating on the surface of RPUF can effectively reduce or prevent flame propagation, improving fire safety. This paper reviews the preparations, properties, and working mechanisms of flame-retardant coatings on RPUF, and identifies high-performance, biological, biomimetic, and multifunctional flame-retardant coatings as the future development trends for surface flame-retardant systems.

Summary: Driven by global environmental issues, the development of green building materials is a focus of immediate attention. In this study, environmentally friendly n-pentane was used as a blowing agent to prepare flame-retardant rigid polyurethane foam (RPUF) with the addition of expandable graphite (EG). The effect of n-pentane content on flame retardancy and compressive properties of RPUF/EG composites was investigated through various tests. The results showed that the n-pentane content had a significant impact on the thermal stability, flame retardancy, and physical properties of the composites, while the cell structure of RPUF matrix influenced the distribution of EG and the flame-retardant efficiency of EG. This research explores the conditions for the application of environmentally friendly RPUF and expands its application prospects.
