| 摘 要：采用熔融共混法制備了尼龍（PA6、PA66）／紅磷母粒／玻纖／偏硼酸鋇復合材料。通過(guò)力學(xué)性能測試、UL94垂直燃燒法、灼熱絲試驗、氧指數（LOI）等研究了偏硼酸鋇對復合材料力學(xué)性能和阻燃性能的影響。力學(xué)性能測試結果表明，加入偏硼酸鋇不影響復合材料的強度，但會(huì )降低缺口沖擊強度；阻燃測試結果表明，偏硼酸鋇在紅磷阻燃尼龍中有良好的協(xié)效作用，可使復合材料阻燃性能達到UL94 V-0（1.6 mm）等級，且灼熱絲起燃溫度（GWIT）可達750℃；氧指數測試結果表明，加入偏硼酸鋇能有效提高復合材料的氧指數。 |

| Abstract：The composite of nylon(PA6, PA66), the masterbatch of red phosphrous, glass fiber and barium metaborate was prepared by twin-screw extruder. The influence of barium metaborate on the properties of the composite has been studied by the mechanical properties, the UL94 Vertical burning method, the Glow-wire test and the Limiting oxygen index (LOI) test. The results of mechanical properties showed that the barium metaborate had no influence on the tensile strength of the composite, but it could deteriorate the impact strength. The results of the flame retardancy indicated that the barium metaborate had a synergism with red phosphrous, and the composites could reach the UL94 V0(1.6 mm) level. Moreover, the glow-wire ignition temperature had reached 750℃, and the LOI has been increased with addition of the barium metaborate. |
