研究了Co(NO_3)_2·6H_2O与1,2,3-丙三酸(H_3tca)、导烟酸(Hina)形成的类分子筛配合物[Co_5(OH)_2(tca)_2(ina)_2(H_2O)_2]·4H_2O(简称为Co_5)与聚磷酸铵(APP)对杨木的协同阻燃作用。锥形量热仪实验结果表明,Co_5与APP协同阻燃试样的总热释放量(THR)比APP阻燃试样的THR降低了18.3%,燃烧过程的质量损失减少了7.7%,二氧化碳产率减少了22.8g/kg,一氧化碳产率减少12.3g/kg。结合热重分析(TGA)、X射线衍射(XRD),表明Co_5或Co_5在高温时产生的丙三酸(H_3tca)、异烟酸(Hina)配体等促进了APP的分解,有助于抑制燃烧,降低失重。APP/Co_5对杨木的阻燃效果优于单一的APP。

The synergistic flame-retarded effects of a similar molecular sieve [Co5(OH)2(tca)2(ina)2 (H2O)2]·4H2O(Co5) and ammonium polyphosphate(APP) on cottonwood was studied by cone calorimeter. The results showed that compared with APP added individually, the combination of Co5 and APP was led to the reduction of total heat release (THR) to 18.3%, the mass loss to 7.7%, y(CO2) to 22.8 g/kg and y(CO) to 12.3 g/kg, respectively. The TGA and XRD analysis also showed that the generation of tricarballylic acid and isonicotinic acid ligands under high temp...
