| titleOfInvention | UV-PU dual-curing 3D printing resin and preparation method and application thereof |
| abstract | The invention provides a preparation method of ultraviolet-polyurethane (UV-PU) dual-curing resin for 3D printing. The dual-curing resin contains prepolymer with the structural general formula as shown in formula 1, formula 2, formula 3 and formula 4, wherein R is 1 Represents methyl or hydrogen, R 2 、R 3 Represents alkylene, cycloalkylene, arylene, R 2 、R 3 Which may be the same or different, R 4 Is arylene, alkylene, cycloalkylene. The low-viscosity polyurethane curing agent added into the UV-PU dual-curing system is equivalent to a diluent in the 3D printing process, and is a curing agent in post-curing, and the curing agent reacts with hydroxyl in an oligomer to further cure, so that the connection strength between layers of a printed part is improved, and the mechanical property and the thermal stability of the printed part are enhanced. The dual-curing 3D printing resin disclosed by the invention has the advantages of high tensile strength, large elongation at break, low shrinkage, low viscosity and the like. |
