摘要

采用硅烷偶联剂KH560作为桥梁，十八烷基三氯硅烷(OTS)作为长疏水链结构，对纳米二氧化钛(TiO

)粒子改性制得OTS-KH560/TiO

溶胶，并整理到织物上制备超疏水非织造织物。利用红外光谱、扫描电镜和X射线能谱表征织物表面化学结构、形貌和元素组成，通过测试水接触角表征织物表面疏水性能，分析TiO

/OTS用量比、焙烘温度、焙烘时间等因素对于整理织物水接触角的影响。此外，研究疏水整理织物的耐酸碱性能、防污性能、油水分离性能和力学性能。结果表明：当TiO

/OTS用量比为0.3 g/0.984 g，焙烘温度和焙烘时间分别为170 ℃和80 s时，整理织物表面的接触角可高达166.5°，且整理后的织物具有良好的耐酸碱性能、防污性能、油水分离能力、吸油性能和力学性能。

Abstract

In this paper

OTS-KH560/TiO

sol was obtained by modifying nano-TiO

particles with silane coupling agent KH560 as a bridge and OTS as a long hydrophobic chain structure

and then finished on the fabric to prepare superhydrophobic fabric. The fabric structure

surface morphology and element composition were characterized by Fourier transform infrared spectrometer

scanning electron microscopy and energy dispersive spectrometer

and the hydrophobic properties of the fabric surface were characterized by testing the water contact angle. The effects of TiO

/OTS dosage ratio

baking temperature and baking time on the contact angle of the finished fabric were further analyzed. In addition

the acid-alkali resistance

anti-fouling performance

oil-water separation performance and mechanical property of the hydrophobic finished fabric were studied. The results showed that when the TiO

/OTS dosage ratio was 0.3 g/0.

984 g

the baking temperature was 170 ℃

and the baking time was 80 s

the water contact angle on the surface of the finished fabric could reach 166.5°. The finished fabric had good acid-alkali resistance

anti-fouling performance

oil-water separation ability

oil absorption performance and mechanical property.
