Nýlega tilkynnti Peking-efnatækniháskólinn um einkaleyfi fyrir uppfinningu á -vetnisgjafi súlfíðnaftalímíðafleiðu ljósvaka sem hentar til loftháðrar herslu á UVLED.
This invention patent discloses a hydrogen-donating thioether naphthalimide derivative photoinitiator suitable for aerobic curing of UVLED, which relates to the field of photosensitive polymers. It is based on the use of existing photoinitiators in UVLED light sources Under irradiation, the problem of poor performance in the presence of oxygen is proposed; the present invention prepares a type of hydrogen donor-containing thioether-type naphthalimide derivative photoinitiator, and provides the above-mentioned hydrogen-containing donor The preparation method of the thioether naphthalimide derivative photoinitiator and its application in the photocuring system; the beneficial effects of the present invention are: ① The photoinitiator prepared by the present invention has significantly extended ultraviolet absorption wavelength, In the wavelength range of the light source, it has good ultraviolet absorption capacity. ② The photoinitiator prepared by the present invention has obvious anti-oxidation and polymerization inhibition effect. ③The migration stability of the photoinitiator prepared by the invention is obviously improved.
