UV光固化型功能溶胶改性棉织物性能研究
|
摘要
以正硅酸四乙酯(TEOS)为前驱体,十二烷基苯磺酸钠(SDBS)为乳化剂,盐酸为催化剂,制备SiO2水溶胶,加入一定量的双键偶联剂γ-甲基丙烯酰氧丙基三甲氧基硅烷(MPS)、十二烷基三乙氧基硅烷(DTES)和光引发剂1173制得UV光固化型功能溶胶。棉织物经功能溶胶浸轧处理和UV光固化后形成超疏水表面,其表面接触角可达150°。当硅烷偶联剂为8%(质量分数)DTES,光固化时间为40s,改性织物表面接触角达到150.63°,织物为超疏水状态。织物经过10次皂洗处理后仍具有一定的疏水效果,织物的拉伸断裂强力提高,而柔软性、透气性、透水性减弱。
With tetraethylorthosilicate(TEOS)as precursor,sodium dodecyl benzene sulfonate(SDBS)as the emulsifier,hydrochloric acid as catalyst,SiO2 hydrosol was prepared.The functional sol was prepared by addingγ-methacryloxy propyl trimethoxyl silane(MPS)double bond coupling agent,dodecyl triethoxy silane(DTES)and light initiator 1173.After the cotton fabric was treated with the functional sol and cured with UV light,the fabric surface was superhydrophobic,and the contact angle reached 150°.When DTES was 8% and the light curing time was 40 s,the contact angle of modified fabric surface was 150.63°,and the fabric surface was superhydrophobic.After soaping 10 times,the treated fabric surface still presented certain hydrophobic effect.The tensile breaking strength was improved,but the softness,gas permeability and water permeability were reduced.
