The invention discloses a preparation process of an efficient universal ultraviolet photoinitiator, which belongs to the field of initiators. The invention relates to a preparation process of an efficient universal ultraviolet photoinitiator. The ultraviolet photoinitiator comprises a free radical type photoinitiator, a cationic photoinitiator and a photosensitizer, and the free radical type photoinitiator comprises MTB, modified 2, 2-dimethoxybenzil ketal, BAPO, 2, 4, 6-trimethyl benzophenone and methyl benzophenone; the cationic photoinitiator is prepared from isopropyl ferrocene hexafluoride acid salt and 1, 3-bis (dicyanomethylene) indene-diphenyl iodonium salt; the photosensitizer is cobalt acetylacetonate; the interval range of absorbable illumination can be expanded, part of visible light and ultraviolet light can be absorbed by the photoinitiator, and the photoinitiator can be used in more application scenes. 本发明公开了一种高效通用型紫外光引发剂的制备工艺，属于引发剂领域。一种高效通用型紫外光引发剂的制备工艺，紫外光引发剂包括自由基型光引发剂、阳离子型光引发剂和光敏剂，由基型光引发剂包括：M
