Abstract

The incorporation of fly ash in polybutyl succinate (PBS) and polybutyl adipate terephtalate (PBAT) in the partial replacement of ammonium polyphosphate and/or melamine polyphosphate is evaluated in the present work. Furthermore, the influence of the surface modification of fly ash with two silanes and titanate coupling agents was also studied. Cone calorimeter experiments, pyrolysis combustion flow calorimeters (PCFCs), and UL94V tests were used to assess the fire performance of the composites. Scanning electronic microscopy, X-microanalysis, and X-ray diffractometry analysis were carried out on cone calorimeter residues in order to access the fire-retardant mode of action. The formation of new components due to the presence of fly ash was highlighted by X-ray diffractometry, indicating the synergistic effects between the flame-retardant system and fly ash. The X-microanalysis results showed that the main fraction of initial phosphorous is present in the cone calorimeter residue, indicating that the proposed system acts in a condensed phase.

摘要

在本研究中，评估了将粉煤灰掺入聚丁二酸丁二醇酯（PBS）和聚己二酸/对苯二甲酸丁二醇酯（PBAT）中以部分替代聚磷酸铵和/或三聚氰胺聚磷酸盐的情况。此外，还研究了用两种硅烷和钛酸酯偶联剂对粉煤灰进行表面改性的影响。采用锥形量热仪实验、热解燃烧流动量热仪（PCFC）和UL94V测试来评估复合材料的防火性能。对锥形量热仪残留物进行扫描电子显微镜、X微观分析和X射线衍射分析，以了解阻燃作用模式。X射线衍射突出了由于粉煤灰的存在而形成的新成分，表明阻燃体系与粉煤灰之间存在协同效应。X微观分析结果表明，初始磷的主要部分存在于锥形量热仪残留物中，表明所提出的体系在凝聚相中起作用。
