Abstract

The invention provides an energy curing composition and its application in the field of energy curing. The energy curable composition includes: (A) sulfonium salt initiator; (B) cationic polymerizable compound; wherein, the sulfonium salt initiator is selected from compounds having structures shown in general formula (I) or general formula (II) one or more of them. The energy-curable composition containing the above-mentioned initiator does not need to dissolve the initiator before mixing with other components, thereby eliminating the emission of VOC; at the same time, the above-mentioned initiator and the cationic polymerizable compound can undergo a curing reaction to form a polymer with a higher molecular weight , which makes the above-mentioned energy-curable composition have good stability, so it hardly produces low-molecular-weight aromatic compounds during the curing process, which greatly improves its safety in the fields of food packaging and human contact materials.

Description

technical field [0001] The invention relates to the field of radiation curing, in particular to an energy curing composition and its application in the field of energy curing. Background technique [0002] The curing system using energy rays such as ultraviolet rays is an effective solution to improve productivity and solve environmental pollution problems in recent years. Although the current photocuring system is mainly a free radical curing system using (meth)acrylate materials, cationic curing systems and free radical curing systems using epoxy, vinyl ether, oxetane and other materials Compared with excellent performance. For example, there is no problem of oxygen inhibition, and it is excellent in terms of surface and film curing; the curing shrinkage is small, and it has good adhesion to most substrates; the life of the active material is long, and it can still slowly undergo dark reaction after light exposure , can make the amount of residual monomers low. Therefor...
