As a novel polymer, polyurethane (PU) has been widely applied in leather, synthetic leather, and textiles due to its excellent overall performance. Nevertheless, conventional PU is flammable and its combustion is accompanied by severe melting and dripping, which then generates hazardous fumes and gases. This defect limits PU applications in various fields, including the leather industry. Hence, the development of environmentally friendly, flame-retardant PU is of great significance both theoretically and practically. Currently, phosphorus-nitrogen (P-N) reactive flame-retardant is a hot topic in the field of flame-retardant PU. Based on this, the preparation and flame-retardant mechanism of flame-retardant PU, as well as the current status of flame-retardant PU in the leather industry were reviewed.
作为一种新型聚合物，聚氨酯（PU）因其优异的综合性能而被广泛应用于皮革、合成皮革和纺织品中。然而，传统的聚氨酯易燃，其燃烧伴随着严重的熔化和滴落，进而产生有害烟雾和气体。这一缺陷限制了聚氨酯在包括皮革工业在内的各个领域的应用。因此，开发环境友好型、阻燃聚氨酯在理论和实践上都具有重要意义。目前，磷-氮（P-N）反应型阻燃剂是阻燃聚氨酯领域的一个热门话题。基于此，本文综述了阻燃聚氨酯的制备、阻燃机理以及阻燃聚氨酯在皮革工业中的现状。
