新型高效沥青阻燃剂燃烧试验分析

Combustion experiment on new and efficient flame retardant asphalt

采用提出的沥青阻燃剂直接燃烧试验方法,对比分析了新型高效沥青阻燃剂ZFR-Ti、中间体ZFR和基准沥青燃烧过程中的燃烧时间、燃烧火焰分布、烧失量。结果表明:沥青直接燃烧法可以在一定程度上反映制备的新型高效沥青阻燃剂的燃烧特性;制备的ZFR-Ti阻燃沥青具有燃烧时间短,引燃温度高,烧失量小的特点,可以较有效的抑制沥青的燃烧,缩短燃烧时间,对隧道使用安全具有重要的意义。

The combustion characteristics was researched and analyzed for new and efficient flame retardant asphalt ZFR-Ti,intermediate ZFR and based asphalt, by the method of immediate combustion experiment.The combustion characteristics comprise with combustion time, flame band distribution,loss on ignition.The reslults show that it can reflect combustion characteristics of a new and efficient flame retardant asphalt in a certain extent by the direct combustion experiment.There are some advantage such as shorter combustion time,higher ignition temperature,smaller ignition loss for preparated ZFR-Ti flame retardant asphalt.It can more effectively inhibit the burning of asphalt and reduce the burning time,which is very helpful and important to rescue tunnel.
