摘　　要：以十八烯、甲基丙烯酸十八烷基酯、甲基丙烯酸丁酯、N-(羟甲基)丙烯酰胺、N,N-二甲基乙醇胺、丙烯酸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1HNMR、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。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~1HNMR,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(720±35)mm/s before and after finishing respectively,showed little change,which solved the airtight problem of traditional hydrophobic waterproof finish.
