纳米SiO2改性含氟聚氨酯-聚丙烯酸酯分散液的制备及性能
Preparation and properties of waterborne fluorinated polyurethane-acrylate by nano-SiO2
摘要
Abstract
The nano‐SiO2/Fluorinated Polyurethane‐acrylate(WSFPUA ) were synthesized by in‐situ surfactant‐free emulsion polymerization with acrylic monomers as solvent and nano‐SiO2 as functional monomer .The structure of WSFPUA was investigated by fourier trans‐form infrared spectroscopy (FT‐IR) ,dynamic laser light scattering (DLS) ,transmission elec‐tron microscope (TEM ) and atomic force microscope (AFM ) .Meanwhile ,the application performance of waterproof、mechanical strength and thermal stability were characterized by contact angle test ,universal testing machine and TGA .The results showed that ,when the nano‐sio2 content was 6% ,the water contact angle of film was 122 .5 °and water absorption was also reduced to 8 .5% ,the tensile stress increased by 15% ,and the decomposition tem‐perature increased 20 ℃ ,respectively .关键词
