Description

一种二苯硫醚酮肟酯化合物、制备方法、组合物及用途 技术领域
本发明涉及一种二苯硫醚酮肟酯化合物、制备方法、组合物及用途。本发明的二苯硫醚酮肟酯化合物,其用于光固化、光学或电子产业。
背景技术
光引发剂是光固化产业,例如涂料、油墨、粘合剂、光刻胶等领域中重要的化学品。光固化材料单体,必需添加光引发剂才能够在一定波长的光源照射下,激发光固化材料中的不饱和基团发生聚合反应,并引起光固化材料的固化。良好的光引发剂是光固化技术成功的关键所在。传统光引发剂包括安息香类、苯乙酮类、二苯甲酮类、硫杂蒽酮类、酰基氧化膦类、芳香重氮盐类、二茂铁类、三氮嗪类、六芳基二咪唑类及肟酯类等。其中肟酯类出现对于光引发产业产生了大幅的进步,例如二苯硫醚酮肟酯OXE-01,特别受重视。
Figure PCTCN2021082749-appb-000001
通常固化配方中常添加蓝、紫外光吸收剂,例如Tinuvin 400或TiO 2,以保护固化后的树脂受光照射而降解,其吸收紫外光波长达到400nm或更长。蓝、紫外光吸收剂也添加于透镜以保护眼睛。这些蓝光-紫外光吸收剂会和光引发剂竞争入射光,造成引发能力下降。OXE-01二苯硫醚酮肟酯类光引发剂虽然吸收较长波长光线,但仍受影响。
因此,增长现有二苯硫醚酮肟酯类光引发剂吸收的波长,一直是产业努力目标。
发明内容
目的:为解决现有技术的不足,本发明提供一种二苯硫醚酮肟酯化合物、制备方法、组合物及用途。本发明二苯硫醚酮肟酯光引发剂在长波长的吸收范围,具有深层固化能力。另一方面,本发明二苯硫醚酮肟酯光引发剂因具有较长波长的吸收范围,可避免配方中其他紫外线或蓝光吸收剂,竞争入射的激发光。
因此,本发明化合物在长波长波段的引发能力较强,可以单独使用或与其他光引发剂搭配使用。
技术方案:为解决上述技术问题,本发明采用的技术方案为:
第一方面,提供一种式(I)化合物或其盐,

预聚合组合物,包括0.05%的光引发剂(对照组OXE-01化合物或实例化合物),0.5mL甲基丙烯酸甲酯。样品中加入或不加入抗蓝光剂Eusorb1990。并通过用氮气吹扫除脱氧气。用420-450nm光线进行聚合。聚合完成后,蒸发剩余的单体,称重剩余固体重。剩余重量越多表示光引发剂的聚合能力愈强。表1测试结果,+号表示光引发剂的引发能力,+号愈多表示光引发剂的引发能力愈强。结果显示,实例化合物在420nm以上,单独使用或与OXE-01搭配,引发能力较OXE-01强。
