摘要：
The photo-induced curing kinetics of cationic UV curing of epoxy resin were investigated with real-time Fourier transform infrared (RT/FT-IR) spectroscopy with an optical fiber ultraviolet curing system. The consumption of epoxy group as a function of time was obtained by monitoring of the oxirane absorbance in the 795-824 cm(-1) region. A spiro orthocarbonate expanding monomer 3,9-diethyl3,9-dihydroxymethyl-1,5,7,11-tetraoxa-spiro[ 5.5] undecane was added to UV curing molding material of 3D printing in different mounts. As a result, when the content of the expanded monomer is increased from 0.5 to 2.0 wt%, conversion rate increased from the original 95-98%, when the amount of expanded monomer is 0.5%, the relative reaction rate of the system achieve the highest.
