摘要
选取3种阻燃剂氢氧化铝、硼酸锌、三氧化二锑分别加入到基质沥青中,利用数显氧指数仪测试其在不同混合气体流量下的氧指数OI,分析混合气体流量是否会影响沥青燃烧性能的测试结果。实验结果表明,在一定范围内,混合气体流量对沥青、阻燃沥青燃烧性能测试结果影响较小,可以按照ASTM D2863-77将混合气体流速控制在30～50mm/s测试沥青的燃烧性能。
Three kinds of flame retardants, including aluminum hydroxide （ATH）, zinc borate （ZB）, and anti- mony trioxide, was separately blended into different asphalt sample, and their combustibility are tested at dif- ferent mixed gas flow. The influence of the mixed gas flow on asphalt combustibility performance was dis- cussed. The experimental result shows that the mixed gas flow within the reasonable range has little effect on the test results of asphalt combustibility performance. And the mixed gas flow can be controlled within the range from 30-50mm/s according to ASTM D2863-77 when combustibility performance of asphalt is tested by using the method of limit oxygen index.
