Abstract

The invention discloses LED photocuring non-solvent type photosensitive transfer printing adhesive for a cover plate glass substrate. The photosensitive transfer adhesive comprises aliphatic polyurethane acrylate, an acrylate reactive diluent, a photoinitiator, an acrylic auxiliary and a silane coupling agent. The LED photocuring non-solvent type photosensitive transfer printing adhesive for the cover plate glass substrate is free of solvents and environmentally friendly, integrates advantages of the transfer printing technology and advantages of the photosensitive technology, and can be particularly used for development through a pure water neutral developing solution. The LED photocuring non-solvent type photosensitive transfer printing adhesive for the cover plate glass substrate has excellent physical performance, resistant to solvents, resistant to cold and hot impact and good in adhesion with the substrate after being cured. The adhesive force of an adhesive layer and the substrate is larger than 4B and environmental pollution is little especially after a boiling test. The problem that existing UV adhesive is poor in adhesion on cover plate glass and not resistant to boiling or solvents is solved, industrial requirements are met, production cost of enterprises is reduced, and benefits are brought to the enterprises.

Description

technical field [0001] The invention relates to the technical field of photocurable transfer adhesives, in particular to LED photocurable solvent-free photosensitive transfer adhesives for cover glass substrates and a preparation method thereof. Background technique [0002] UV transfer glue is generally a one-component UV-curable glue, which is mainly formed on the surface of the material through a mold. It has the advantages of easy use, fast curing speed, high light transmittance, convenient operation, and environmental friendliness. It has been widely used In various plastic film industries. The transfer adhesive formula generally includes: reactive diluent monomers, photoinitiators, acrylate prepolymers, additives, etc. UV curing is ultraviolet light curing, and UV is the English abbreviation of ultraviolet light. UV curing refers to the use of medium and short waves of ultraviolet light to irradiate the photoinitiator in the liquid raw material, so that the initiator...
