| 摘 要： | 以聚氯乙烯(PVC)改性酚醛树脂为原料,采用熔融纺丝法制备出PVC阻燃酚醛纤维.通过SEM、DMA、TG、Fr-IR等分析手段,对PVC阻燃酚醛纤维的结构和性能进行了研究.与纯酚醛纤维相比,PVC阻燃纤维的韧性和阻燃性提高,但其热稳定性和残碳率稍有降低.当PVC含量为0.5wt％时,其拉伸强度从123 MPa提高至150 MPa,极限氧指数从32.1％提高至38.5％,在空气气氛下600℃的残碳率从87.4％降至70.9％,在氮气气氛下1 000℃的残碳率从62.8％降至59.7％.

| Abstract: | Phenolic fibers modified by PVC(Polyvinyl Chloride) have been prepared by melt-spinning.SEM(Scanning Electron Microscope),DMA(Dynamic Mechanical Analysis),TG(Thermogravimetric Analysis) and FT-IR(Fourier Transform Infrared Spectrometer) were employed to characterize the structure and performance of the PVC flame-retardant phenolic fibers.In comparison the PVC flame-retardant phenolic fibers with the pure phenolic fibers,the addition of 0.5wt% PVC in the precursor resin obviously increases mechanical strengt... |
