Synthesis Experiment

In this experiment, we examine the impact of photoinitiator and reactive diluents for the UV curing of epoxy resin and Urethane acrylate in detail, so as to provide a theoretical basis for obtaining a satisfactory light curing system. We conducted a number of UV curing experiments, discussed the key influencing factors of the success in Synthesis experiment, explored and researched the Reaction mechanism to some certain extent. The performance was tested after curing, according to the orthogonal experiment method, we analyses the effect of different factors.

Different Molecular Weight

Three kinds of commercially available epoxy acrylate reactive prepolymers with different molecular weight (MW) were used to formulate the UV-curable adhesives by addition of photo-initiator, reactive diluent, crosslinker and other additives as necessary. The MW of the said prepolymers were measured by gel permeation chromatography (GPC), while the structural characterization of the prepolymers before and after UV-curing was made by FTIR. Thermal stability of two kinds of UV-cured prepolymers with distinct MW and MW distribution was detected by thermogravimetric (TG) analysis.Lap shear strength of the adherents at different temperature were tested and compared with a known superior UV-curable adhesive (Loctite 3493). Adhesion strength of the adhesives at room temperature were all higher than 15 MPa which were more than the reported riveting intensity (10.3 MPa).

The Impact

In this study, polyhedral oligomeric silsesquioxane (POSS) were blenged with epoxy acrylate (EA) and photoinitiator to prepare nanocomposites through UV-curing process. The vinyl-POSS nanoparticles were added to EA by physically blending at loadings between 0% and 15wt%. Through the FTIR analysis, we found that the POSS nanocomposites didn’t affect the extent of UV curing reactions; the curing reactions were performed to be completed in all POSS containing composites. The XRD analysis convinced the existing of phase separation between EA matrix and vinyl-POSS monomer. The impact resistance and coating adhesion were all enhanced by POSS nanocomposites at low content.

Kinetics Of

In ouder to prepare the waterborne UV-curable polyurethane acrylate coatings, the anionic polyurethane acrylate emulsifier and bisphenol-S eopxy acrylate were synthesized. The curing process, kinetics and properties of waterborone UV-curable epoxy acrylate/polyurethanes acrylate coating were investigated by FTIR, DSC and DMA. The results show that the static initial curing temperature Ti is 52.36 oC, peak temperature Tp is 71.58 oC, the finished temperature Tf is 89.15 oC. The curing reaction can be described by two-parameter autocatalytic Šesták-Berggren (S-B) model.This coating has a better UV-curing property. The dynamic mechanical analysis showed that the glass transition temperature Tg of coating film is 52.70 oC.
