摘要:以氧化石墨烯(GO)为功能填料,氟硅丙烯酸酯(FSiAc)乳液为功能黏合助剂,制备了 GO/FSiAc 复
合乳液整理剂,并通过轧-烘-焙工艺对亚麻织物进行整理。利用 FTIR、TEM 和 DLS 表征了 GO/FSiAc 复合乳液
的结构和粒径分布;通过 XPS 和 SEM 表征了整理亚麻织物的表面元素和形貌;考察了软单体(丙烯酸丁酯,
BA)和硬单体(甲基丙烯酸甲酯,MMA)的质量比及 GO 的质量浓度对整理亚麻织物的热稳定性、防紫外线
性、拒水性、物理机械性能的影响。结果表明,GO 在 FSiAc 乳液中具有良好的分散性,并均匀地覆盖在亚麻
织物表面。当 m(BA)∶m(MMA)=7∶3,GO 质量浓度为 4 g/L 时,亚麻织物表现出优异的拒水性和防紫外线性
能,其水接触角为 148.48°,紫外线防护系数(UPF)为 179.77,紫外线 UVA 波段的透过率为 0.63%。与原始亚
麻织物相比,GO/FSiAc 复合乳液整理的亚麻织物的耐热性、断裂强力和断裂伸长率分别提升 60.67 ℃、153 N
和 11.1%,同时保持良好的透气性能。经过 20 次皂洗测试后,水接触角仍为 142.00°,UPF 为 162.22,UVA 波
段的透过率为 0.94%,说明整理后亚麻织物具有良好的耐久性。

Abstract: Graphene oxide/fluorine-silicon acrylate (GO/FSiAc) composite emulsion finishing agent was
prepared by using GO as functional filler and FSiAc emulsion as functional adhesive auxiliary and then
used to the finishing of flax fabric by roll-dry-bake process. The structure and particle size distribution of
GO/FSiAc composite emulsion were characterized by FTIR, TEM and DLS. The surface elements and
morphology of the finished flax fabric were characterized by XPS and SEM. The effects of mass ratio of
soft monomer (BA) to hard monomer (MMA) and mass concentration of GO on heat resistance, UV
protection property, water repellency and physical and mechanical properties were investigated. The results
showed that GO had good dispersion in FSiAc emulsion and uniformly covered the surface of flax fabric.
Under the conditions of m(BA)∶m(MMA) = 7∶3 and mass concentration of GO of 4 g/L, the finished flax
fabric showed excellent water repellency and UV protection property with water contact angle of 148.48°,
