Abstract

The invention provides a self-triggered ultraviolet light-cured oligomer and a preparation method thereof. The invention provides a synthetic method of the ultraviolet light-cured self-triggered oligomer. The oligomer is synthesized from 2-hydroxy-2-methyl-1-phenyl-1-propanone, an isocyanate compound, acrylic acid (methylacrylic acid)hydroxyl ester, a catalyst, an aid and the like, is capable of generating free radicals under ultraviolet irradiation and can be automatically cross-linked and cured. An additional ultraviolet light initiator does not need to be added during the ultraviolet lightcuring of the oligomer, so that the oligomer has low odor, and micromolecule fragment is not produced; and after the oligomer is cured into a film, the hardness is of the film is high, and the curingdegree can reach 90%.

Description

technical field

[0001] The invention belongs to the field of preparation of UV (ultraviolet light curing) oligomers, and particularly relates to a preparation method of ultraviolet light curing oligomers capable of self-initiation. Background technique

[0002] UV-curable coatings are one of the most environmentally friendly coating varieties at present. Due to their advantages of energy saving, high efficiency, and environmental protection, UV-curable coatings are an environmentally friendly coating variety that has emerged in my country in the past 20 years. With the rapid development of science and technology and modern industry, ultraviolet (UV) curing materials are outstanding in today's material field. As a key component of UV-curable materials, photoinitiators are widely used in the fields of UV-curable coatings, inks, adhesives, microelectronics and printing plates.

[0003] Since the concept of photoinitiators was first proposed in 1968 in the environmentally frien...
