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3 300 cm-1处的吸收峰强度有所减弱,而在1 700～1 720 cm-1处得到加强;当nTDI:nPEG=1:1和1:2时,接枝后红外谱图在3 300及1 700～1 720 cm-1处的吸收峰强度基本相同.nTDI:nPEG=1:3时稳定化效果最佳.
Chemical disposal was used to bring the activity group onto the surface of Kevlar fiber for the purpose of surface grafting modification. The interracial 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 interracial constitution was analysed. It is concluded that the stabilization took place on the surface. The intensity of the bands relented at about 3 300 cm^-1 and was reinforced at about 1 700-1 720 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 1 700-1 720 cm^-1 are almost the same.
