PVC阻燃酚醛纤维的制备及其性能OA北大核心CSCDCSTPCD
Preparation and Properties of PVC Flame-Retardant Phenolic Fibers
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 …查看全部>>
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 conparison the PVC flame-retardant phenolic fibers with the pure phenolic fibers, the addition of 0.5wt% PVC i…查看全部>>
