光敏树脂由高功率、短波长紫外光固化向低功率、长波长的可见光固化的方向发展是该类树脂的一个发展趋势,紫外光固化树脂由于其对可见光不敏感的特点,使得它具有优异的稳定性而易于保存,而可见光固化树脂因对自然光较为敏感,其应用和贮存受到了更严格避光条件的限制,给人们的使用带来不便,为了改善可见光固化树脂使用时稳定性不够、易固化、不易保存的缺点,本文对影响可见光树脂的稳定性的两个组分,即光引发剂和光稳定剂进行了实验与分析,确定了能够有效改善可见光固化树脂使用及存储稳定性的配方,并对其效果进行了验证。
The development of the photosensitive resin from high-power, short-wavelength UV curing to low-power, long-wavelength visible light curing is a trend of such resins. Due to its insensitivity to visible light, the UV-curable resin has excellent Stability and easy to save, and visible light curing resin because of the more sensitive to natural light, its application and storage are subject to more stringent dark conditions, to bring inconvenience to people, in order to improve the use of visible light curable resin is not enough stability, easy Curing, not easy to save the shortcomings of this article on the stability of visible light resin, the two components, namely, photoinitiators and light stabilizers were tested and analyzed to determine the effective use of visible light curable resin and storage stability of the formula, And its effect has been verified.
