制备了一种新型的天然材料基三聚氰胺壳聚糖磷酸（MPCS）阻燃剂。分析了其对聚乙烯醇（PVA）热性能和燃烧性能的影响。热重分析数据表明，MPCS增强了材料在高温下的热稳定性。热重分析/红外光谱分析（TGA-IR）结果表明，MPCS显著降低了可燃挥发产物的产率。微尺度燃烧量热（MCC）数据显示，峰值放热率（PHRR）、总放热率（THR）和放热量（HRC）均有所降低，表明MPCS提高了材料的阻燃性。
A novel natural material-based flame retardant melamine chitosan phosphate (MPCS) has been prepared. Its impact on thermal properties and flammability performance of polyvinyl alcohol (PVA) was analyzed. Thermogravimetric analysis data exhibited that MPCS enhanced the thermal stability of materials at high temperature. The results of thermogravimetric analysis/infrared spectrometry (TGA-IR) showed that MPCS decreased the yield of flammable volatilized products greatly. Microscale combustion calorimetry (MCC) data showed that peak heat release rate (PHRR), total heat release (THR) and heat release capacity (HRC) all reduced, which indicated that MPCS improved the flame retardancy of materials.
