针对夏季高温天气带来的危害,采用硅烷偶联剂KH560对氧化锌纳米颗粒进行改性,通过浸轧烘工艺将其整理到棉织物表面,制备了硅烷偶联剂改性氧化锌棉织物。通过粒径测试确定了改性氧化锌纳米颗粒的最佳分散条件。通过紫外线防护系数(UPF值)测试确定了棉织物的最佳整理工艺。傅里叶变换红外光谱和X射线衍射分析证明氧化锌纳米颗粒接枝到棉织物上。硅烷偶联剂改性氧化锌棉织物的UPF值达到52.29,摩擦100次后UPF值仍达到47.6;传热系数为(63±0.3)W/(m2·K),可见光区的反射率达到80%,红外热成像测试结果表明硅烷偶联剂改性氧化锌棉织物相较于普通棉织物可以实现1.85℃的降温效果。
To address the harm caused by high temperatures in summer,the silane coupling agent KH560 was used to modify the zinc oxide nanoparticles.The modified zinc oxide nanoparticles were treated on the surface of the cotton fabric by padding and drying process to prepare silane coupling agent-modified zinc oxide cotton fabric.The optimum dispersion conditions of the modified zinc oxide nanoparticles were determined by particle size test.The optimum finishing process of cotton fabric was identified by the ultraviolet protection factor (UPF value) test.Fourier transform infrared spectroscopy and X-ray diffraction analysis proved that the zinc oxide nanoparticles were grafted onto cotton fabrics.The UPF value of silane coupling agent-modified zinc oxide cotton fabric reached 52.29,and the UPF value still remained at 47.6 after 100 times of friction.The thermal transfer coefficient was (63±0.3)W/(m2·K),and the reflectivity in the visible region reached 80%.The infrared thermal imaging test results demonstrated that the silane coupling agent-modified zinc oxide cotton fabric could achieve a cooling effect of 1.85℃ compared with ordinary cotton fabric.
