Synthesis and properties of fluorosilicone modified polyacrylate emulsion
Fluorosilicone modified polyacrylate emulsion is synthesized by doping fluorosilicone functional monomer into polyacrylate emulsion,and the hydrophobic finishing effect of polyester fabric was evaluated.FTIR,DSC and XPS are used to characterize the emulsion.The results show that the fluorosilicone modified polyacrylate emulsion exhibits good storage stability,and the maximum particle size density occurs at 115 nm.The finished polyester fabric has superhydrophobic properties with a static water contact angle of 152.3°and a rolling water contact angle of 9.1°.The finished polyester fabric has hydrophobic properties after washing 30 times.The wear properties of the finished polyester fabric,such as air permeability and moisture permeability,have little change.
