摘要/Abstract

摘要： 随着光固化3D打印技术的发展,制备收缩率小、凝胶含量高,性能符合使用要求的光敏树脂极为重要,以纯丙烯酸酯(2官能度,2-AE)、聚氨酯丙烯酸酯(6官能度,6-PUA)为低聚物,二缩三丙二醇二丙烯酸酯(TPGDA)为稀释剂,2,4,6-三甲基苯甲酰基-二苯基氧化膦(TPO)为光敏剂,利用正交试验法配制光敏树脂溶液并通过3D打印完成样品制备。以收缩率、凝胶含量、黏度及硬度为评价指标,通过综合平衡法对测试结果进行分析,研究结果表明,光敏树脂溶液制备的最佳配方为:两种低聚物(纯丙烯酸酯、聚氨酯丙烯酸酯)质量比为2∶1,稀释剂质量分数为57.6%,光敏剂质量分数为3%。样品性能参数为:收缩率4.7%,凝胶含量96.6%(质量分数),黏度105 mPa·s,邵氏硬度80 HD。

Abstract: With the development of UV curing 3D printing technology, it is very important to prepare photosensitive resin with low shrinkage and high gel content. The photosensitive resin was prepared by using pure acrylate (2 functionality, 2-AE) and urthane acrylate (6 functionality, 6-PUA) as prepolymer, tri (propylene glycol) diacrylate (TPGDA) and 2,4,6-trimethylbenzoyl diphenylphosphine oxide was as diluent and photoinitator, respectively. Shrinkage rate, gel content, viscosity and hardness were evaluating indicator.The photosensitive resin solution was prepared by orthogonal experiment and the sample was prepared by 3D printing. Taking shrinkage ratio, gel content, viscosity and hardness as evaluation indexes, the test results were analyzed by comprehensive balance method. The experiment results show that, the best combination is that ratio of two oligomers is 2∶1, the mass ratio of diluent is 57.6%, the mass ratio of photosensitizer is 3%. The performance parameters are: shrinkage rate 4.7%, gel content 96.6% (mass fraction), viscosity 105 mPa·s, Shore hardness 80 HD.

Key words: photosensitive resin, shrinkage rate, gel content, pure acrylate, urthane acrylate
