摘要
以甲基丙烯酸甲酯、丙烯酸异冰片酯、甲基丙烯酸十二烷基酯、六氟丙烯酸丁酯、二甲基丙烯酸丁二醇酯、3-氯-2-羟丙基甲基丙烯酸酯为单体,偶氮二异丁基脒盐酸盐为引发剂,合成阳离子含氟丙烯酸酯乳液,并应用于棉织物的拒水拒油整理.用红外光谱对聚合物进行表征,研究了交联剂对胶膜接触角及整理棉织物拒水拒油性能的影响.结果表明:未加交联剂,胶膜接触角达111.58°;加2%的三官能团氮丙啶交联剂,胶膜接触角可以提高到118.35°.经该乳液整理后的织物不仅具有较好的拒水性能,而且有突出的拒油性能,拒水达100分,拒油达6级;同时,耐久性良好,水洗30次以后,拒水为90分,拒油为5级.
Cationic fluorinated acrylic emulsions were synthesized with methyl methacrylate, isobornyl acrylate, lauryl methacrylate, hexafluorobutyl acrylate, butylene glycol dimethacrylate, 3- chloro- 2- hydroxypropyl methacrylate as monomers and azobis isobutyl amidine hydrochloride as the initiator, which was applied in water and oil repel ent finishing of cotton fabrics. The polymer emulsion properties were characterized with infrared spectrometer. The effects of the crosslinking agent on the contact angle of the film and the water and oil repel ent properties of the finished fabrics were investigated. The results showed that the contact angle of the film was 111.58°, when 2% tri- functional aziridine crosslinking agent was added, the contact angle of the film was increased to 118.35°. The results showed that the finished fabric not only had good water repel ence but also had outstanding oil repel ence. The waterproofing level was 100 points, the oil repel ent level was grade 6; at the same time, the durability was excellent, after 30 times of washing, the waterproofing level was 90 points, and the oil repel ent level was grade 5.
