摘要
在阳、非离子表面活性剂及过硫酸铵引发剂的作用下,将甲基丙烯酸十二氟庚酯(RfAA)与甲基丙烯酸十二醇酯(LMA)、丙烯酸羟丙酯(HPA)、甲基丙烯酸二甲氨乙酯(DM)、乙烯基三乙氧基硅烷(VTES)在水相乳液共聚,制得一种硅烷化氟代聚丙烯酸酯(FLHDV)乳液,用红外光谱(IR)和核磁共振氢谱(1H-NMR)对FLHDV主组分的结构进行表征,用透射电镜(TEM)、纳米粒度仪和Zeta电位分析仪等仪器对FLHDV乳液的粒径等进行测定,并以涤纶织物作为应用对象,考察FLHDV乳液的应用性能。结果表明:FLHDV乳液带有正电性,ζ电位为+47.64 mV,平均粒径为116.2 nm;FLHDV可在涤纶纤维表面成膜,经其处理后的涤纶织物,拒水性可达到100分,拒油等级达到5级,静态接触角达到142.5°,表现出良好的拒水拒油效果。
A novel siloxane fluorinated polyacrylate emulsion（FLHDV） was prepared by copolymer-ization of dodecafluoroheptyl methacrylate（RfAA）,lauryl methacrylate（LMA）,2-hydroxypropyl acrylate（HPA）,dimethylaminoethyl methacrylate（DM） and vinyltrioxethylsiloxane（VTES） with the（NH4）2S2O8 as a water soluble initiator and cationic/nonionic surfactants as mixed emulsifier.Chemical structure of FLHDV was characterized by infrared spectrum（IR） and 1H nuclear magnetic resonance（1H-NMR）.The particle sizes and the latex distribution of the emulsion were investigated by TEM,ζ voltage analysis and other instruments.The performance of polyester fabric treated by FLHDV emulsion was also studied.The experimental results show that the FLHDV emulsion carried positive charges with a mean ζ voltage of ＋ 47.64 mV and with an average particle size of 116.2 nm.The smooth film of FLHDV can be formed on polyester fabric surfaces and conferred the treated polyester fabric with an excellent water-and oil-repellency.As a result,the treated polyester fabric exhibited good water-and oil-repellent properties with water-repellency degree of 100,oil-repellency rating of 5,and water static contact angle of 142.5°.
