摘要
研究了在 5 14nm Ar+ 激光下丙烯酸环氧树脂在染料、叔胺、紫外引发剂协同引发下的固化过程。研究发现 ,激光在树脂中的穿透服从 L ambert- Beer定律 ,固化深度主要由光照射能量和染料浓度决定。在引发剂组成及浓度一定时 ,固化深度及固化质量随光照射能量的对数的增加而线性增加。在反应初期 ,固化速率基本不变 ,为零级反应。反应后期 ,反应速率下降 。
The curing process of an epoxy acrylics based photosensitive resin under a 514 nm Ar + laser beam and the initiation of a synergistic photo initiator composed of a dye, a tertiary amine and an UV photo initiator was studied. It is observed that the transmission of the light in the resin is in agreement with the Lambert Beer's Law. The curing depth is mainly decided by the light energy and the dye concentratin. For a given formula and concentration of the initiator, the curing depth and the curing mass of the resin was observed to increase linearly with the increase of the logarithm of the light energy. In the initial stage, the rate of the curing reaction is almost constant and the reaction is basically a zero order reaction. With the process of the reaction, the rate decreases and the reaction is no further a zero order reaction.
