Preparation and performance of bisphenol-A type epoxy acrylate photosensitive resin for ultraviolet cured 3D direct ink writing printing
摘要
Abstract
A free radical photosensitive resin suitable for ultraviolet(UV)cured 3D direct ink writing printing was synthe-sized using bisphenol-A epoxy acrylate(EA)as a prepolymer,1,6-hexanediol diacrylate(HDDA)as a monomer,and 2,4,6-trimethylbenzoyl diphenylphosphine oxide(TPO)as an initiator.The resin could form a cross-linked network under UV ir-radiation.The effect of TPO content on the surface drying time,gel rate,and volume shrinkage of photosensitive resin were investigated.The results indicated that when 6 g TPO was added,the surface drying time of the cured resin was the short-est,its gel rate was highest,and its volume shrinkage was largest.According to these results,the effect of the mass ratio of prepolymer to monomer on the surface drying time,viscosity,gel rate,volume shrinkage,and mechanical properties of the photosensitive resin were investigated.The results demonstrated that the photosensitive resin containing 6 g TPO had the shortest surface drying time,lower viscosity,the largest gel rate,and excellent mechanical properties at an EA/HDDA of 20/9.This suggests that the developed photosensitive resin is suitable for use in UV cured 3D direct ink writing printing.关键词
