目的 合成出一种用于棉织物整理的阳离子型含氟苯丙乳液。方法 选用全氟烷基乙基丙烯酸酯(PFEA)、丙烯酸丁酯(BA)、甲基丙烯酸甲酯(MMA)、苯乙烯(ST)及N-羟甲基丙烯酰胺(N-MA)等5种单体为原料,以2,2-偶氮二(2-甲基丙基咪)二盐酸盐为引发剂,采用半连续种子乳液聚合法合成了一种阳离子型含氟苯丙乳液。通过FT-IR、GPC、DSC及激光粒度仪对共聚乳液进行了表征。结果 由于有机氟链段的自趋表能力,导致乳胶膜的疏水性随核壳比例的变化很小,但玻璃化温度Tg会因硬单体含量的增加而略有上升。同时,引发剂用量的增加会提高单体转化率,降低凝胶率,增大其质均分子量。FT-IR测试表明,聚合物中成功地引入了氟碳基团及其他官能团,激光粒度仪测得乳液的平均粒径为0.196 m,分布较窄。SEM显示经过整理后的棉织物表面较光滑平整,通过测定评级,防水达到95分,拒油达到6级,效果良好。结论 核壳乳液聚合制备阳离子型含氟苯丙乳液反应过程平稳,将其用于纯棉织物的整理可使织物表面获得优异的防水拒油性能。 |

The work aims to synthesize a cationic fluorinated poly-styrene-acrylic latex, which can be used in cotton fabric finishing. With 2,2'-azobis(2-methylpropionamidine)dihydrochloride as initiator, cationic fluorinated poly-styrene-acrylic latex was synthesized from perfluoroalkylethyl acrylate, butyl acrylate, methyl methacrylate, styrene and n-hydroxymethyl acrylamide by semi-continuous seed emulsion polymerization . The final copolymerization emulsion was characterized with FT-IR, GPC, DSC and LPSA. Hydrophobicity of the latex film varied slightly with core-shell ratio since organo-fluorine chain segment could automatically migrate to the surface. However, its glass transition temperature rose slightly with the increase of hard monomer content. In addition, as initiator dosage increased, monomer conversion rate and weight-average molecular weight increased, and coagulation rate decreased. The FT-IR test showed that fluorocarbon group and other functional groups were successfully incorporated into copolymers. Furthermore, average diameter of narrowly distributed emulsion measured by laser particle analyzer was 0.196 m. The finished cotton fabric had a smooth and flat surface, and was tested to show 95 points in water-proofing and grade 6 in oil-repellency. Reaction process of cationic fluorinated poly-styrene-acrylic latex prepared by core-shell emulsion polymerization is stable. After being processed with it, the cotton fabric surface exhibits excellent waterproof and oil-repellent properties. |
