摘要

摘要: 通过熔融共混方法制备苯基膦酸铈（CeHPP）与十溴二苯醚（DBDPO）复配阻燃玻璃纤维增强聚对苯二甲酸乙二醇酯（GF/PET）复合材料。采用热失重分析（TGA）测试研究了DBDPO-CeHPP对GF/PET复合材料热稳定性的影响。同时利用垂直燃烧（UL-94）、极限氧指数（LOI）及微型锥形量热（MCC）测试表征DBDPO-CeHPP-GF/PET复合材料的阻燃性能。使用SEM对DBDPO-CeHPP-GF/PET复合材料的残炭表面形貌进行观察分析。结果表明，DBDPO与CeHPP复配后对DBDPO-CeHPP-GF/PET体系的热性能和阻燃性能都有很大的影响。其中，GF/PET复合材料与DBDPO和CeHPP质量比为91：6：3时，DBDPO-CeHPP-GF/PET复合材料的LOI高达29.5%，可以通过UL-94 V-0级。在MCC测试中，与纯GF/PET复合材料相比，该配比的DBDPO-CeHPP-GF/PET复合材料总热释放（THR）、热释放速率峰值（PHRR）及热熔（HRC）分别下降了10.2%、13.1%和12.8%。结合残炭形貌的测试结果，对DBDPO-CeHPP-GF/PET复合材料的阻燃机制进行了适当的解释分析。

Abstract: The combinations of cerium phenylphosphonate (CeHPP) and decabromodiphenyl oxide (DBDPO) were used for flame retardancy of glass fiber reinforced poly(ethylene terephthalate)(GF/PET) composites by using melt blending. Thermograviment analysis(TGA) was employed to investigate the thermal decomposition behavior of the flame retardant DBDPO-CeHPP-GF/PET composites. The combustion properties of DBDPO-CeHPP-GF/PET composites were measured by using limiting oxygen index (LOI), underwriters laboratories 94 (UL-94) and microscale combustion calorimeter (MCC). SEM was used to investigate the microtopography of char residues of DBDPO-CeHPP-GF/PET composites. The thermal properties and flame retardance of DBDPO-CeHPP-GF/PET composites are significantly improved by the incorporation of the combinations of CeHPP and DBDPO. For DBDPO-CeHPP-GF/PET composite with mass ratio of GF/PET composites:DBDPO:CeHPP of 91:6:3, the UL-94 V-0 classification and high LOI (29.5%) are achieved. The total heat release (THR), peak heat release rate (PHRR) and heat release capacity (HRC) of DBDPO-CeHPP-GF/PET composites at this ratio are respectively reduced by 10.2%, 13.1% and 12.8% comparing with the pure GF/PET composites. And the flame retardant mechanism of DBDPO-CeHPP-GF/PET composites was analyzed based on the SEM results of char residues.
