Abstract:
      The effect of monofunctional monomers on the rheological and photosensitive properties of resin-based Al2O3 slurry was studied from the perspective of molecular structure and functional groups. The bifunctional group monomer 1,6-hexanediol diacrylate (HDDA) and triple functional group monomer trimethylolpropane triacrylate (TMPTA) were used as raw materials, adding monofunctional monomers X with a selected volume ratio of VHDDA:VX:VTMPTA=6:3:1. The photosensitive resin was fabricated by magnetically stirring at room temperature (RT), and the rheological properties of monofunctional monomers X and resins were studied. The resin-based alumina slurries with solid content of 30vol%~50vol% were prepared by ball milling, the 3D printing process based on stereolithography (SL) was realized and the alumina bodies were fabricated. The monofunctional monomers acryloylmorpholin (ACMO), 2-phenoxyethyl acrylate (2-PHEA), and hydroxyethyl acrylate (HEA) with hydrophilic groups and high photopolymerization activity were used, and the resins with high activity and photopolymerization accuracy were fabricated, benefiting for fabricating Al2O3 slurries with superior rheological and photosensitive properties.
