立体光造型成型材料的制备
Preparation of Stereo Lithography Materials
摘 要
以环氧树脂E-51和丙烯酸为基本原料,合成了立体光造型成型材料光敏树脂,通过比较不同树脂体系的固化度及显微硬度,优化了光敏树脂合成工艺;用硅烷偶联剂处理后的SiC纤维对光敏树脂进行了增强,比较了光敏树脂增强前后固化件的抗拉强度.结果表明:预聚物与单体三翔甲基丙烷三丙烯酸的质量比为2∶1、光引发剂质量分数为3.5%时,树脂体系固化度最高,硬度指标较理想;光敏树脂经SiC纤维增强后,抗拉强度得到提高.

Abstract
Photosensitive resins were synthesized using epoxy resin E-51 and acrylic acid as basic raw material,then photosensitive resins’ mixture ratio was optimized through comparing the different photosensitive resins’ UV-curing state and microhardness;and on this condition photosensitive resins were modified using disposed silane resin acceptor SiC fiber,and then solidification’s mechanical behavior such as photosensitive resins and modified photosensitive resins’ microhardness and tensile-strength were tested and matched.The result indicates that when the mass percent of prepolymer and monomer is 2∶1,content of photo-initiator is 3.5%,the photosensitive resins’ UV-curing state is the highest,performance index of hardness is optimal;and the modified photosensitive resins’ tensile-strength has great improvement.
