含氟丙烯酸酯拒水剂的制备

Synthesis of fluorine containing polyacrylate water repellent

以苯乙烯(SM)、丙烯酸异辛酯(2-EHA)与甲基丙烯酸十二氟庚酯(Actyflon-G04)为反应单体,采用半连续种子乳液聚合方式,制备了含氟丙烯酸酯拒水剂.分析了含氟丙烯酸酯拒水剂的最佳合成工艺,对制备的共聚物进行傅立叶转换红外光谱表征,并将其处理到棉织物上.最佳合成工艺为:m(SM)∶m(2-EHA)=3∶2,Actyflon-G04 50%(对单体总质量),乳化剂2.5%(对单体总质量),引发剂0.8%(对单体总质量),聚合反应温度为80℃,保温时间为1.5 h.将合成的共聚物处理到棉织物上,整理后织物对水的接触角可达136.5°,具有良好的拒水性能.

Fluorine containing polyacrylate water repellent was prepared using styrene（SM）,isooctyl acry late（2-EHA）,hexafluorobutyl methacrylate（Actyflon-G04） as the monomers with semi-continuous seed emul sion polymerization method.The optimal synthesis process of fluorine containing polyacrylate water repellent was analyzed.The prepared copolymer was characterized by Fourier transform infrared spectroscopy,and was applied in cotton fabric.The results showed that the optimum synthesis condition was： 3∶2 of SM and 2-EHA mass ratio,50% of Actyflon-G04 on the total mass of monomers,2.5% of emulsifier on the total mass of monomers,0.8% of initiator on the total mass of monomers,80 ℃ of polymerization temperature,1.5 h of holding time.And the synthetic copolymers was applied in cotton fabric,the water contact angle was up to 136.5°,with good water repellency.
