A method for preparing water-resistant and anti-aging water-based coating

ActiveCN118146690Bevenly blendedC-F bond energy highCoatingsCompatibilizationPolymer
The invention relates to the technical field of water-based coatings, and discloses a method for preparing a water-resistant and anti-aging water-based coating. The C-F bond energy in an organic fluorine silicon polymer is high. Compared with hydrogen atoms, fluorine atoms are more easily embedded in the polymer, thereby blocking the channel for water molecules to migrate into the interior of a coating film. The terminal hydroxypropyl polysiloxane can form a hydrophobic layer on the surface of the coating film, while the alkenyl organic fluorine silicon polymer and the alkenyl in a modified nano titanium dioxide structure can polymerize with acrylic monomers, thereby increasing the crosslinking density and forming a dense surface layer. After film formation, the organic fluorine and organic silicon in the polymer are arranged outwardly in a directional manner, thereby reducing the surface energy of the coating film, thereby making the coating film have excellent water resistance. The nano titanium dioxide particles have a small size effect and a quantum size effect, and have a strong absorption effect on ultraviolet rays. The modified nano titanium dioxide has good compatibility with the coating, thereby improving the anti-aging performance of the water-based coating.
