Embodiment 1

[0058]

[0059] Preparation:

[0060](1) Put 30g of isobornyl acrylate IBOA, 18.68g of tricyclodecane dimethanol diacrylate EM2204, 48g of mercapto-modified aliphatic urethane acrylate oligomer Genomer 7302, 0.02g of BYK-377 and 0.5g of GENORAD16 in In the glass container, use a stirrer to stir to obtain a uniformly mixed first mixture; then add 0.8gTPO radical photoinitiator and 2g184 free radical photoinitiator to the first mixture and continue stirring until the free radical photoinitiator is completely dissolved to obtain the second mixture;

[0061] (2) Carry out primary filtration with a 0.45 μm glass fiber membrane, and then perform secondary filtration with a 0.22 μm PP membrane to obtain a filtrate;

[0062] (3) Under a vacuum degree of 0.1 MPa, filter under reduced pressure for 1 hour to remove air bubbles in the filtrate, and finally obtain a photocurable transparent ink for 3D inkjet printing.

[0063] Carry out performance test to the 3D inkjet printing photo...

Embodiment 2

[0072]

[0073] Preparation:

[0074] The preparation method of the photocurable transparent ink for 3D inkjet printing in this embodiment is basically the same as that of Embodiment 1, except that the time for decompression and degassing is adjusted to 2 hours.

Abstract

The invention provides transparent photocuring ink for 3D ink-jetting printing and a preparation method thereof. The transparent photocuring ink for 3D ink-jetting printing comprises acrylate monomers, sulfhydryl compounds, surfactants, photoinitiators and assistants. The transparent photocuring ink for 3D ink-jetting printing has the advantage of capability of inhibiting proneness to yellowing, muddiness and obscurity of printed products.

Description

technical field [0001] The invention relates to printing technology, in particular to a photocurable transparent ink for 3D inkjet printing and a preparation method thereof, belonging to the technical field of 3D inkjet printing. Background technique [0002] 3D inkjet printing technology is based on the working principle of inkjet printers. Under the excitation of digital signals, the ink in the nozzle chamber forms droplets in an instant, and is ejected from the nozzle at a certain speed and frequency. The layers are solidified into shape, and finally a 3D object is obtained. [0003] 3D inkjet printing inks can be divided into light-curable inks and temperature-curable inks according to different curing sources. Light-curable inks usually contain photoinitiators, oligomers (also called oligomers) and monomers. Photoinitiators are subject to The irradiation of light is excited to generate free radicals to promote the polymerization of oligomers and monomers to cure the in...
