电子束辐照诱导丙烯酸接枝尼龙66织物的改性研究
利用电子束引发丙烯酸单体接枝尼龙66织物,研究不同接枝条件对接枝反应的影响。利用红外光谱仪（FTIR）、热重分析仪（TGA）、扫描电镜（SEM）以及YG065型织物强力仪研究了接枝前后织物的化学结构、热性能、表面形貌及力学性能变化,并通过垂直燃烧评价接枝织物的抗熔滴性能。结果表明：红外谱图1720.2cm-1等处出现单体中羧基的特征吸收峰,说明丙烯酸成功接枝到尼龙66上。接枝后,尼龙66织物的抗熔滴性得到显著改善,主要因为交联状炭层骨架对纤维熔体的支撑作用,但力学性能有一定程度降低。随着接枝率的增加,尼龙66的初始分解温度逐渐降低,成炭性能明显提升,织物损毁长度变短,熔滴速率更低,而断裂强力有...

| Abstract_FL | Acrylic acid was grafted onto nylon 66 fabric by the electron beam irradiation method. Effects of different grafting conditions on grafting reaction were investigated.Fourier transform infra-red spectroscopy(FTIR),thermo gravimetric analyzer(TGA),scanning electron microscope(SEM) and YG065 type fabric strength tester were used to characterize the chemical structures,thermal prop-erties,surface morphology and mechanical properties of these prepared nylon 66 fabric samples.And the anti-dripping performance was evaluated by the vertical burning.The results show that in FTIR spectrum new absorption peeks at 1720.2 cm-1 and other wave numbers are assigned to the carboxyl groups,which imply that acrylic acid is successfully grafted to the nylon 66 molecular.The anti-drip-ping performance of nylon 66 fabric is improved significantly after grafting.It can be attributed to the cross-linked char layer which subsequently provides a support for the melting fiber.However,the mechanical properties of grafted samples decrease to some extent.With the increase of grafting ratio, the onset temperatures of grafted samples decrease gradually,while the char-forming performance en-hances significantly.Besides,the damage length and droplet velocity of grafted samples become shor-ter and lower,and the tensile strength at break increases slightly. |
