紫外光固化中常用引发剂对紫外可见光(UV-VI)吸收的影响因素研究

A Study on the Factors of Common Initiators in UV Curing Influencing UV-VI Absorption

以紫外光固化体系中引发剂对紫外可见光(UV-VI)吸收的研究,以0.1%(质量分数)引发剂浓度研究了常见10余种引发剂的吸收光谱图。通过对吸收光谱的实验,考察了不同极性环境、不同浓度对吸收光谱的影响,以及吸收光谱对有色体系、LED固化体系固化配方设计的指导作用。

UV-VI absorption of initiators in UV curing systems was studied.The absorption spectra of more than ten common initiators were studied with the initiator concentration being 0.1%(w.t.%).Through the experiment of the absorption spectra,the influence of different polar environments and different concentrations on absorption spectra and the guidance of absorption spectra for designing curing formulas of colored systems and LED curing systems were studied.
