| Abstract:The waterborne cationic perfluorinated acrylate soap-free emulsion was prepared using perflu-orinated alkyl ethyl acrylate (FEA), styrene(St), butyl acrylate(BA), methacryloxyethyl trimethylammonium chloride(DMC) as monomers and using azob-isisobutyronitrile (AIBN) and (2,2′-Azobis(2-methylpropionamide)dihydrochloride)(AIBA) as initiator and isopropyl alcohol as solvent. The effects of the content of fluorinated emulsion as surface sizing agent on the properties of paper were investigated. The copolymer was characterized by infrared spectroscopy (IR), contact angle, and scanning electronmicroscopy (SEM). The experimental results showed that the water-oil repellency of paper were good when the ratio m(St)∶m(BA)∶m(FEA)∶m(DMC)=3∶3∶2∶1.2 and the content of FEA was 20%.The increase of tensile strength and folding strength were 22.3% and 38.2%. |
