Abstract

The invention discloses an LED-ultraviolet light (LED-UV)-cured transfer printing adhesive and a preparation method thereof.The transfer printing adhesive is prepared from, by mass, 10%-15% of modified epoxy acrylate, 20%-35% of aliphatic urethane acrylate, 30%-40% of specially functional acrylic ester, 10%-20% of active diluent, 4%-6% of photoinitiator and 2%-5% of an adhesion promoter.A using method of the prepared transfer printing adhesive comprises the steps that firstly, the transfer printing adhesive is applied to a workpiece; secondly, a transfer printing adhesive coating is covered with a transfer printing ink film, and then the pattern transfer printing effect is achieved through LED ultraviolet light curing.The prepared transfer printing adhesive is a total-solid-content UV adhesive, effectively utilizes an LED-UV low-energy curing light source, is quick in deep curing and low in energy consumption, has the excellent adhesion and the good water resistance and can be widely applied to various workpieces needing pattern transfer printing.

Description

technical field [0001] The content of the present invention relates to the field of ultraviolet light curing materials, in particular to an LED ultraviolet light (LED-UV) curing adhesive for ink transfer printing and a preparation method thereof. Background technique [0002] Traditional solvent-based adhesives contain a large amount of VOC solvents, slow curing speed, low production efficiency, and cause great harm to human health during production and use. With the increasing calls for environmental protection, the environmental protection of adhesives has become an important development trend. In recent years, ultraviolet (UV) curing transfer adhesive has become the most concerned new type of environmentally friendly adhesive due to its advantages of environmental protection, high efficiency, high quality, and wide adaptability, and has a huge development prospect. The LED ultraviolet light (LED-UV) curing adhesive in the present invention is a new type of light curing a...
