摘要

研究了聚磷酸铵(APP)和硼酸(BA)对松针阻燃和热降解的协同作用。热重分析(TGA)表明，聚磷酸铵和硼酸体系的存在增加了松针的焦渣，降低了松针的热解温度。衍生热重分析(DTG)表明，聚磷酸铵和硼酸使松针的降解峰向低温方向移动。锥量热试验结果表明，经聚磷酸铵和硼酸(APP/BA = 3/2)处理的松针HRR、THR、SPR、TSP和质量损失率(%)显著低于其他样品。因此，APP和BA系统对松针的整体效果优于APP单独处理。

THE SYNERGISTIC EFFECT OF BORIC ACID AND AMMONIUM POLYPHOSPHATE ON THE THERMAL DEGRADATION AND FLAMMABILITY OF PINE-NEEDLES

The synergistic effect of ammonium polyphosphate (APP) and boric acid (BA) on the flame retardancy and thermal degradation of pine needles was investigated. Thermogravimetric analysis (TGA) showed that the presence of an ammonium polyphosphate and boric acid system increased the char residue and decreased the pyrolysis temperature of the pine needles. The derivative thermogravimetric analysis (DTG) showed that the ammonium polyphosphate and boric acid had shifted the degradation peaks of the pine needles to lower temperatures. The cone calorimetry test results showed that the values of HRR, THR, SPR, TSP and the mass loss (%) of the pine needles treated with ammonium polyphosphate and boric acid (APP/BA = 3/2) were significantly lower than the other samples. Therefore, the APP and BA system had a better effect on the pine needles overall than the APP alone.
