Optimization of UV Curable Acrylated Polyester-Polyurethane/Polysiloxane Ceramer Coatings Using a Response Surface Methodology

摘要

Dual UV and moisture curable acrylated polyester, organic/inorganic hybrid coatings were prepared using a coupling agent, and tetraethylorthosilicate (TEOS) oligomers. An acrylated polyester resin based on adipic acid, neopentyl glycol, trimethylolpropane and acrylic acid were synthesized. Tetraethylorthosilicate (TEOS) oligomers were prepared through the hydrolysis and condensation of TEOS with water and 3-(triethoxysilyl)propylisocyanate (TEOSPI) was used as the coupling agent between organic and inorganic phases. As the reactive diluent trimethylolpropane triacrylate (TMPTA) was used. The experiments were planned according to the three-factor, threelevel Box-Behnken design. Reaction kinetics, fracture toughness, and tensile properties were evaluated in terms of the concentrations of TEOS oligomers, TEOSPI and TMPTA concentrations.
