Synthesis of Novel Anionic Fluorinated Polyacrylate Emulsion and its Application in Leather Waterproofing

Abstract:

Novel anionic fluorinated polyacrylate emulsion (FLHA) was synthesized and characterized using Infrared spectrum (IR). Then it was used as waterproofing agent to treat wet blue leather and the effects of various parameters, such as dose of fluorinated acrylate emulsion, processing time, temperature, etc., on hydrophobic property of the treated crust leather were also investigated using single factor experimental method. Results showed that water contact angle (WCA) on the grain and flesh layers of the resultant leather had similar rule controled by dose of the FLHA, processing time and temperature and increased with augment of those factors. The most preferable processing parameters of the above factors were 6% (based on the weight of the treated wet blue leather), 60 minutes and 30 °C, repectively. Thus, WCA on the grain and flesh layers of the resultant leather could attain 130° and 136°.
