研究目的
Investigating the photocrosslinking characteristics of UV-curable acrylate monomers and the effect of 2-ethylhexyl acrylate on photocuring behaviour of bisphenol-A glycerolate diacrylate, acrylic acid and methyl methacrylate.
研究成果
The study successfully synthesized and characterized bisphenol-A glycerolate diacrylate and investigated its photocuring behaviour with acrylate monomers. The addition of 2-ethylhexyl acrylate was found to impart flexibility to the UV-cured compositions without significantly affecting the curing rate. The developed formulations showed promising results for applications in laminated glasses.
研究不足
The study focused on the effect of 2-ethylhexyl acrylate on photocuring behaviour and mechanical properties, but other factors such as environmental conditions and long-term stability were not extensively explored.
1:Experimental Design and Method Selection:
The study involved the synthesis and characterization of bisphenol-A glycerolate diacrylate, followed by its formulation with acrylate monomers. Photocrosslinking characteristics were investigated using a differential photocalorimeter equipped with a UV radiometer.
2:Sample Selection and Data Sources:
Formulations were prepared with varying concentrations of 2-ethylhexyl acrylate to study its effect on photocuring behaviour.
3:List of Experimental Equipment and Materials:
Differential scanning calorimeter (DSC 7020, Hitachi, Japan) with PDC 7 unit, FTIR Spectrometer (ATR module of Cary 630 FTIR, Agilent Technologies), Universal Testing Machine (Fine Spavy associates), and UV curing chamber.
4:Experimental Procedures and Operational Workflow:
The formulations were exposed to UV radiation of 365 nm at an intensity of 10 mWcm-
5:The heat of photoreaction, curing rate, and degree of conversion were studied. Data Analysis Methods:
The heat flow values were used to calculate curing rate and degree of conversion. FTIR analysis was performed to quantify C=C bond conversion.
