混有着色剂的光敏树脂光固化技术研究

Laser cure of photosensitive resin mixed with coloring agent

研究了混入不同着色剂的液态光敏树脂在激光扫描照射下树脂单层固化厚度的变化规律,比较了不同着色剂对树脂固化程度的影响.进一步研究了经表面改性的着色剂加入液态树脂后对树脂固化程度的影响.实验结果表明:随着色剂种类和加入量的变化,树脂固化程度发生明显变化.使用表面改性的方法,可以改善着色剂在液态树脂中的分散性以及着色树脂的固化程度.使用MTS Nano Indenter XP型纳米硬度计对固化树脂进行力学性能检测,结果显示混入改性着色剂的固化树脂的表面可承受的压力和弹性模量有显著提高.

To compare the impact of coloring agents on resin curing,the experiment was carried out to study the curing layer depth of resin mixed with different kinds of coloring agents under laser scanning.And then surface modification was performed to some kind of coloring agent in order to improve resin curing.The experimental results indicate that resin curing is affected by the species and quantity of coloring agent;surface modification is an effective way to improve the dispersibility in liquid resin and increas...
