Abstract

The compatibility and coating ratio between flame retardant materials and expanded polystyrene (EPS) foam is a major impediment to achieving satisfactory flame retardant performance. In this study, we prepared a water-based intumescent flame retardant system and methylene diphenyl diisocyanate (MDI)-coated expandable polystyrene microspheres by a simple coating approach. We investigated the compatibility, coating ratio, and fire performance of EPS- and MDI-coated EPS foam using a water-based intumescent flame retardant system. The microscopic study revealed that the water-based intumescent flame retardant materials were successfully incorporated with and without MDI-coated EPS microspheres. The cone calorimeter tests (CCTs) of the MDI-coated EPS containing water-based intumescent flame retardant materials exhibited better flame retardant performance with a lower total heat release (THR) 7.3 MJ/m, peak heat release rate (PHRR) 57.6 kW/m, fire growth rate (FIGRA) 2027.067 W/ms, and total smoke production (TSP) 0.133 m. Our results demonstrated that the MDI-coated EPS containing water-based intumescent flame retardant materials achieved flame retarding properties as per fire safety standards.

摘要

阻燃材料与发泡聚苯乙烯（EPS）泡沫之间的相容性和包覆率是实现令人满意的阻燃性能的主要障碍。在本研究中，我们通过一种简单的包覆方法制备了一种水基膨胀型阻燃体系和二苯基甲烷二异氰酸酯（MDI）包覆的可膨胀聚苯乙烯微球。我们使用水基膨胀型阻燃体系研究了EPS和MDI包覆的EPS泡沫的相容性、包覆率和燃烧性能。微观研究表明，水基膨胀型阻燃材料成功地与有或没有MDI包覆的EPS微球结合。含有水基膨胀型阻燃材料的MDI包覆的EPS的锥形量热仪测试（CCT）显示出更好的阻燃性能，总热释放（THR）为7.3 MJ/m，峰值热释放速率（PHRR）为57.6 kW/m，火灾增长速率（FIGRA）为2027.067 W/ms，总产烟量（TSP）为0.133 m。我们的结果表明，含有水基膨胀型阻燃材料的MDI包覆的EPS根据消防安全标准实现了阻燃性能。
