Abstract

The invention relates to a compound type odor-less light initiator and an ultraviolet curing coating material. The compound type odor-less light initiator is prepared from the following components in percentage by weight: 30 to 70 percent of zinc oxide and 30 to 70 percent of macromolecular light initiator, wherein the macromolecular light initiator is prepared from a hydroxy-containing light initiator, isocyanate and hydroxy-containing acrylic acid. The compound type odor-less light initiator disclosed by the invention is capable of effectively solving a smell problem generated by volatile organic small molecules released after photolysis of an organic light initiator, the initiation efficiency is high, and the conversion rate of the ultraviolet curing coating material can be increased, so that the smell and volatile organic matters released by residual unreacted raw materials in the ultraviolet curing coating material can be further reduced, and a paint film after photopolymerization is odor-less and is good in performance.

Description

technical field

[0001] The invention relates to a photoinitiator, in particular to a compound odor-cleaning photoinitiator and an ultraviolet light curing coating. Background technique

[0002] UV-curable coatings contain almost no volatile organic solvents, and have the advantages of low energy consumption, fast response, clean and environmentally friendly. A UV-curable coating formulation system includes at least the following three components: ① Photosensitive resin (or prepolymer, oligomer), is the source of the most basic physical and chemical properties of coatings and paint films, and determines the overall formula The curing rate of the system and the performance of the material; ②Reactive diluent, mainly used to adjust the viscosity of the coating formulation system; ③Photoinitiator, under the irradiation of ultraviolet light, produces active groups that can initiate photopolymerization of the above two substances (free radical or cation).
