Embodiment 1
[0027] A dlp-type 3D printing light-curing material that can be used for clinical dental temporary crowns, its quality ratio is as follows:
[0028] Nano-organic-inorganic hybrid UV resin 30g; high-strength aliphatic urethane acrylate 30g; high-toughness aliphatic urethane acrylate 30g; monofunctional free radical acrylate monomer 30g; difunctional free radical acrylate monomer 10g; Free radical acrylate monomer 10g; inorganic silver-based antibacterial agent 10g; pigment 5g; 2,4,6-trimethylbenzoyl-diphenylphosphine oxide 10g.
[0029] The nano-organic-inorganic hybrid UV resin adopts POSS-PCL hybrid UV resin, and the resin highly reactive primary hydroxyl polycaprolactone oligomer and polyamino POSS monomer react to synthesize POSS-PCL hybrid material, and then The POSS-PCL hybrid material was grafted to the (meth)acrylic group capable of radical polymerization to synthesize nano-organic-inorganic hybrid UV resin.
