Abstract

The invention discloses a polymerizable photoinitiator and a preparation method thereof. A formula of the photoinitiator is as shown in the specification. The photoinitiator has advantages that compatibility of the photoinitiator to photopolymerization systems is improved, photoinitiator residual in a photocuring process is sharply reduced, and the photoinitiator can further serve as a monomer forsynthesis of macromolecular photoinitiators. Therefore, the photoinitiator has a promising application prospect in the field of photocuring.

Description

Technical field:

[0001] The invention relates to a novel polymerizable type II photoinitiator and a preparation method thereof. Background technique:

[0002] UV curing technology is an environmentally friendly green technology in the fields of coatings, inks, adhesives, etc. Compared with traditional solvent-containing systems, UV curing technology has outstanding features such as no solvent emission, high efficiency, and energy saving. The main body of the material is generally composed of oligomers, monomers and photoinitiators, which are fully cured under the action of sufficient ultraviolet light. With the application of UV light curing materials more and more widely, some unexpected problems have appeared, and the initiator itself The free radicals of free radicals have no or low initiation activity, and remain in the cured film after quenching. The toxicity caused by the migration and precipitation of residual initiators to the surface has become a potential major hid...
