采用聚磷酸铵(APP)和磷氮类阻燃剂(NEWRAY911)对苎麻/苯并噁嗪树脂层压板进行阻燃改性，并通过万能材料试验机、极限氧指数(LOI)、垂直燃烧实验、热失重仪(TG)和微型燃烧量热仪(MCC)对层压板性能进行分析。实验结果表明：经过APP改性后的层压板LOI有明显的增加，但只有当APP添加量达到7%时层压板的垂直燃烧才能通过V0级，且APP过多的添加也使层压板的力学性能有较大的损伤。采用NEWRAY911阻燃改性苎麻织物不仅可以使层压板的阻燃性能得到改善，同时也减少 APP 的添加量，使苎麻/苯并噁嗪树脂层压板在阻燃改性的同时保持了良好的力学性能。经APP和NEWRAY911改性后的层压板明显减缓了分解速率、燃烧热释放量及释放速率，提高了热分解的残炭量。

Ramie/benzoxazine resin laminates were modified by ammonium polyphosphate (APP) and nitrogen-phosphorous flame retardants (NEWRAY911). Their properties were analyzed by universal testing machine, limiting oxygen index testing instrument, thermogravimetric analysis, and microscale combustion calorimeter. It was shown that the limiting oxygen index (LOI) of laminates increases obviously by the addition of APP, however, the LOI does not reach V0 level until the addition of APP reaches 7%. The mechanical properties of laminates becomes worse when a superfluous amount of APP is added. Using flame retardant finishing of ramie fabric with NEWRAY911, the flame retardant properties of laminates can be ameliorated with less addition of APP and the desirable mechanical property of the laminates is kept. For the laminates coordinately modified by APP and NEWRAY911, the degradation rate, total heat release, and heat release rate are slowed down and the char residue of thermal decomposition is heightened substantially.
