Abstract
Digital light processing vat photopolymerization (DLP 3D printing) technique are being widely applied in prototype design and engineering parts preparation. DLP 3D printing technique adopts acrylate resin as raw material which generate cross-linking network through free radical polymerization, hence fabricated parts are usually brittle and fragile. Although molecular modification for acrylate is an effective way to improve the flexibility of the printed part, the high modulus of the parts decreased greatly. In recent years, core–shell nanoparticles (CSP) have proved to be an effective toughening agent for epoxy, nevertheless the dispersibility and stability in acrylate and corresponding toughening effects are still unclear. In this work, by taking advantage of the excellent dispersibility of CSP in epoxy, acrylate modified CSP emulsions were prepared by in situ modification approach. In brief, the CSP with a silicone core and epoxy grafted shell was first prepared and dispersed in the epoxy matrix. Remained epoxy functional groups were modified to acrylate functional groups through a ring-opening reaction with acrylate acid. Compounded with oligomers and reactive diluents, a toughened 3D printable UV-curable resin was prepared. The characterization results showed that the flexural strength was improved by 30% at an addition of 3% w/w of CSP, and the impact strength was improved by 147.9% at an addition of 7% w/w of CSP. This in situ modified toughened UV-curable resin also provides a higher stability for a longer shelf life. Dimensional accuracy tests also proved as-prepared UV-curable resin can print a refined structure. This low viscosity, high printing accuracy and good stability of toughened CSP/UV-curable resin nanocomposite has potential contribution to the applications for vat photopolymerization in engineering field.
