摘　　要：用IR、EDS、XRD、TGA等仪器研究了纳米杂化阳离子氟代聚丙烯酸酯(FLDV-SiO2)乳液的物化和应用性能.结果发现:FLDV-SiO2乳液带有正电,其ζ电位平均为+45.26mV,主要由粒径(Φ)处于50～200nm和300～1 000nm区间的两种乳胶粒所构成;FLDV-SiO2可在纤维表面形成一种较粗糙疏水膜,该膜包裹在纤维表面,能使处理后涤纶织物的静态接触角达到156.4°、拒水性达到100分、拒油等级达到6级;乳液用量及固化温度等对FLDV-SiO2的应用性能有影响.在乳液用量<2g/100gH2O条件下,用FLDV-SiO2乳液处理后的涤纶织物其拒水拒油性会随乳液用量的增加而增强.另外,高温烘焙固化有利于FLDV-SiO2表现出较佳的应用效果.A nano-SiO2 hybrid fluorinated polyacrylate emulsion（FLDV-SiO2） as well as its physical and performance properties on fabrics were investigated by IR,EDS,XRD,TGA and other instruments. Experiment results indicated that the FLDV-SiO2 emulsion was cationic and had a mean ξ voltage of about ＋45.26 inV. The particle sizes （Ф） of FLDV-SiO2 emul sion were between 50-200 nm and 300-1 000 nm. FLDV-SiO2 could form a rugged polymer film on the polyester fibers/fabrics, which could provide the treated fabrics with a strong hy- drophobicity and oil-repellency. As a result, the water contact angle on such fabrics reached as high as 156.4°,and the water- and oil-repellency respectively achieved 100 and grade 6. In addition, the amount of FLDV-SiO2 emulsion and the cure temperature have effects on FLDV-SiO2 performance. As the dosage of FLDV-SiO2 emulsion increased in application, the water- and oil-repellency of fabrics treated by FLDV-SiO2 were significantly raised. Mean- while, the high temperature allowed FLDV-SiO2 to show better performance on the treated fabrics.
