Description

technical field [0001] The invention relates to the technical field of ultraviolet curing coatings, in particular to an environment-friendly high-strength UV glue. Background technique [0002] Ultraviolet light curing (i.e. UV curing) refers to the chemical reaction of photosensitive substances in the system under the action of ultraviolet light to produce active fragments, which trigger the polymerization and crosslinking of active monomers or oligomers in the system, so that the system can be coated from a liquid state. The layer instantly becomes a solid coating. Ultraviolet light curing glue (UV glue) has been widely studied due to its many outstanding advantages such as fast curing speed, environmental friendliness, low energy consumption, and no solvent volatilization. It is mainly used in: electronics industry, optical product industry, medical equipment, decoration materials industry. [0003] As people pay more and more attention to environmental protection, the ...
