磷酸脒基脲与聚磷酸铵协同阻燃的木粉/HDPE复合材料
Synergistic Fire Retarding Study of Guanylurea Phosphate and Ammonium Polyphosphate Treated Wood Flour/HDPE Composite
摘要
Abstract
Abstract:The effects of adding ammonium polyphosphate (APP),guanylurea phosphate (GUP) and the mixtures of them on fire retardancy,thermal degradation behavior and mechanical properties of wood flour/high density polyethylene (WF/HDPE) composite were studied using cone calorimetry (CONE),limited oxygen index (LOI),thermogravimetric analysis (TGA) and mechanical test.The results of CONE showed that APP significantly reduced the heat release of WF/HDPE composite,while made the smoke emission increased.When compounding GUP with APP by an appropriate ratio,the composite displayed both low heat release and low smoke release,which indicated a good synergistic effect in fire inhibition and smoke suppression.The results of TGA showed that compounding GUP with APP made the initial thermal decomposition temperature of WF/HDPE composite decreased and improved the char residue.In addition,compounding GUP with APP not only increased the limited oxygen index but also had less negative effects on mechanical properties of the composite.关键词
