摘要

Non halogen flame retardant researches have achieved great progress; however, theoretical works are much lagged. Here we show a model of an efficient Flame Retardant Carpet (e-FRC) based on the synergistic flame retardant system of phosphorus and hydroxyl compounds that can give ABS UL 94 V-0 efficiently. This model is further extended to explain the high efficient flame retardancy of phosphonates by proposing a surfactant structured intermediate from pyrolysis. The smart intermediate self-assembles on charred polymer matrix, forming an anisotropy molecular membrane, with one side of hydrocarbon groups and the other of inorganic groups. The organic side adheres onto polymeric char, and inorganic side facing the fire, forms an Oxygen Shielding Screen (OSS). The OSS together with charred layer underneath constitutes an e-FRC. This e-FRC structure can be found in earlier reports. It can explain all present existing efficient flame retardant systems.
