摘要
用阻燃剂氢氧化铝(Al(OH)3)对PTT地毯进行阻燃改性,用辐射热源法和锥形量热仪对阻燃PTT进行测试分析。当阻燃剂的质量分数为10%,PTT地毯的阻燃性能达到GB 8624-2006标准中的Bfl级。PTT地毯的临界辐射通量试验的主要影响因素是辐射板温度、点火火焰高度和基材。
Polytrimethylene terephthalate(PTT) carpet was modified by fire retardant aluminum hydroxide (Al(OH) 3 )- Its flame retardant property was tested and analyzed through radiant heat source and the cone calorimeter. The PTT carpet with 10% flame retardant could reach the Bn level of GB 8624-2006 standard. The main factors that influence the critical heat flux test of PTT carpet are temperature of radiant panel, height of the ignition flame and substrate.
