摘    要:文章试图通过化学处理方法在Kevlar纤维表面引入活性基团,从而达到对Kevlar纤维进行表面接枝改性的目的。采用红外光谱分析甲苯-2,4-二异氰酸酯(TDI)接枝kevlar纤维的表面组成,用己内酰胺及聚乙二醇PEG(400)对接枝物进行封端稳定化处理;分析了不同nTDI:nPEG值对其产物表面组成的影响。实验结果表明,当nTDI:nPEG=1:3时,接枝后红外谱图在3300cm^-1处的吸收峰强度有所减弱,而在1700~1720cm^-1处得到加强;当nTDI:nPEG=1:1和1:2时,接枝后红外谱图在3300及17001720cm^-1处的吸收峰强度基本相同。nTDI:nPEG=1:3时稳定化效果最佳。

Abstract:Chemical disposal was used to bring the activity group onto the surface of Kevlar fiber for the purpose of surface grafting modification. The interfacial constitution of the grafting of toluene-2,4-diisocyanate (TDI) onto Kevlar fiber was determined by Fourier transform infrared spectroscopy. In the mean time, hexyl-lactam stabilization and poly-glycol (400, PEG) stabilization on the grafted product were also studied. The effects of different nTDI:nPEG ratios on the production's interfacial constitution was analysed. It is concluded that the stabilization took place on the surface. The intensity of the bands relented at about 3300 cm(-1) and was reinforced at about 1700-1720 cm(-1) when the ratio of nTDI:nPEG = 1:3, but when the ratio is 1:1 and 1:2, the bands at about 3 300 and 1700-1720 cm(-1) are almost the same.
Keywords:Kevlar fiber  Toluene-2  4-diisocyanate(TDI)  Poly-glycol(400  PEG)  Hexyl-lactam(PL)  Grafting reaction  FTIR spectra
