中文摘要:
      目的 探讨利乐包装废弃物/高密度聚乙烯阻燃木塑材料的热重动力学。 方法 以利乐包装废弃物和高密度聚乙烯为原材料, 以马来酸酐接枝聚乙烯、 硬脂酸金属皂和聚磷酸铵及三聚氰胺分别为耦联剂、 润滑剂和阻燃剂, 增强材料为玄武岩纤维; 采用挤出法和注塑法制备阻燃性TPP/HDPE木塑复合材料, 并采用热重分析方法, 在升温速率为 5, 10, 20 ℃/min 的条件下, 探讨 TPP/HDPE 复合材料在 20~700 ℃的热降解动力学行为。结果 Kissinger法研究结果显示,与仅采用聚磷酸铵和三聚氰胺作为阻燃剂的TPP/HDPE复合材料相比, 采用聚磷酸铵、 三聚氰胺和玄武岩纤维作为复合阻燃剂, 可以提高木塑复合材料的活化能, 添加玄武岩纤维可进一步提高利乐包装/聚乙烯复合材料的热稳定性; 采用Coats-Redfern方法计算聚磷酸铵、 三聚氰胺和玄武岩纤维作为复合阻燃剂的TPP/HDPE复合材料的动力学参数表明,复合材料热解反应第1阶段和第2阶段的表观活化能分别为35.26, 171.16 kJ/mol。结论 研究结果为解决纸/铝/塑包装废弃物污染的回收综合利用探索了一条新的途径, 研制的复合材料具有良好的力学和防火性能, 可用于地板、 墙板等建筑领域及包装领域。
英文摘要:
      The aim of this study was to discuss the thermogravimetric kinetics of Tetra pak/high-density polyethylene flame retardant composites. In this paper, a wood/plastic composite with good properties was developed by extrusion followed by injection moulding using TPP waste and high-density polyethylene as raw materials, ammonium polyphosphate and melamine as intumescent fire retardants, and basalt fiber as a reinforced phase. Dynamics of thermal degradation of the developed composites was investigated by thermogravimetric analysis at 20~700 ℃ in the heating rate of 5, 10 and 20℃/min under N2 atmosphere. The Kissinger method showed that the activation energy of basalt fiber reinforced Tetra-pak/HDPE fire retardant composites was higher than that of the composites without any basalt fiber, demonstrating that the thermostability of Tetra-pak/HDPE fire retardant composites could be improved by the incorporation of basalt fiber into the Tetra-pak/HDPE matrix. The kinetic parameters and equations were also obtained by Coats-Redfern method for the basalt fiber reinforced Tetra-pak/HDPE fire retardant composites, and the results showed that the apparent activation energy of the first and the second thermolysis stage was 35.26 kJ/mol and 171.16 kJ/mol, respectively. The developed composite could be used as an alternative raw material in construction, packaging and other application fields. The utilization of Tetra pak packaging waste for value added products should be considered as new approach for paper/plastic/aluminum waste management and prevention of municipal solid waste environmental pollution.
