和单乙烯基封端聚二甲基硅氧烷(Vi-PDMS)为单体制备了无氟防水剂。采用 HNMR、凝胶渗透色谱仪、纳米
粒度及电位分析仪、光学接触角仪对其进行了结构表征和性能测试。将其用于纯棉织物的整理,对整理织物的
性能进行了测试。结果表明,当 Vi-PDMS 相对分子质量为 2000、含量为单体总质量的 3%、制备的无氟防水剂
质量分数为 10%时,整理织物的防水效果最佳。水在整理织物表面的接触角可达 157°,滚动角为 6°;整理织物
在机械压力摩擦 1000 次、强酸强碱浸泡 10 min、水洗 5 个周期后仍具有良好的疏水效果。整理前、后织物透气
性变化不大,透气率分别为(697±54)和(720±35) mm/s,解决了传统涂层型防水织物疏水而不透气的问题。

Abstract: A fluorine-free waterproofing agent was prepared from monomers of octadecene, octadecyl
methacrylate, butyl methacrylate, N-(hydroxymethyl)acrylamide, N,N-dimethylethanolamine, acrylic acid

and vinyl-terminated polydimethylsiloxane (Vi-PDMS), and characterized by HNMR, gel permeation
chromatography, nano size and potential analyzer, and optical contact angle analyzer for structure and
property analyses. The fluoride-free waterproofing agent obtained was then applied in finish of cotton fabric,
of which the properties were investigated. The results showed that the finished fabric displayed the best
waterproofing when the content of Vi-PDMS with a relative molecular mass of Vi-PDMS of 2000 was 3%
of the total mass of monomers, and 10% of the fluorine-free waterproof agent prepared. The water contact
angle of the fabric finish could reach 157°, with the rolling angle of 6°. Meanwhile, the finish fabric still
maintained good hydrophobic effect after 1000 times of mechanical pressure friction, 10 min of strong acid
and strong alkali immersion, and 5 cycles of washing. Moreover, the air permeability, (697±54) and
