摘要
为研究聚醚醚酮(PEEK)织物的阻燃性能,为其在阻燃方面的应用提供理论参考,分别通过垂直燃烧试验、烟密度试验和锥形量热仪试验研究自行纺制的PEEK织物的阻燃性能,并用扫描电镜观察织物燃烧后的残余炭层。结果表明,PEEK织物不易燃,燃烧时火焰传播速度很慢,具有自熄性,最大烟密度(无焰)为2.06。在热辐射强度为75 kW/m2条件下,燃烧过程最大热释放速率为183 kW/m2,CO最大浓度为9×10-6mL/mL,释放的毒性气体非常少,燃烧产生的残余炭层非常致密。
To give theoretical basis for the application of poly（ether-ether-ketone） （PEEK） fabric, the flame-retardant properties of PEEK fabric was studied by vertical flammability test, smoke density test and cone calorimeter test, and the morphology of the combustion residue of PEEK fabric was examined by scanning electron microscope （SEM）. The results showed that PEEK fabric was difficult to ignite. Once burning, the flame spreaded slowly with the largest smoke density 2.06. Under the heat radiate intensity 75 kW/m^2 , the maximum heat release rate was 183 kW/m^2 , and the maximum proportion of poisonous gas CO was 9×10^-6 mL/mL, and little smoke and poisonous gas release. The combustion residue of PEEK fabric is rather compactive.
