Abstract

The invention belongs to the technical field of ink, and in particular relates to an LED curable UV adhesive for laser transfer paper. The adhesive comprises the following components: 40-60 parts of epoxy soybean oil modified water-based polyurethane, 5-10 parts of a photoinitiator, 10-15 parts of isooctyl acrylate, 8-20 parts of hexanediol diacrylate, 5-10 parts of trimethylolpropane triacrylate,20-40 parts of a nano rare earth material and 1-5 parts of an auxiliary agent. According to the LED curable UV adhesive for the laser transfer paper and preparation method provided by the invention,the isooctyl acrylate, the hexanediol diacrylate and the trimethylolpropane triacrylate are used as monomers, and the nano rare earth material is added, so that the a peak value of ultraviolet light absorbed by the product can be increased, the final brightness and optical laser effects of the product can be improved while environmentally-friendly requirements can be guaranteed, and the product has excellent scratch resistance.

Description

technical field [0001] The invention belongs to the technical field of ink, in particular to a laser transfer paper LED curing UV glue and a preparation method thereof. Background technique [0002] Most of the offset printing inks on PVC film materials such as credit cards and bus cards are solvent-based. The synthesis process uses a large amount of organic solvents. During construction, a large amount of organic solvents will be volatilized and discharged into the air, causing pollution to the environment. It is not conducive to environmental protection, especially benzene solvents are not conducive to the health of operators. [0003] However, the current solution to the above problems is to avoid the use of benzene-containing solvents and use UV high-pressure mercury lamps for curing. This method is more difficult to dry, and the brightness of the finished product is slightly worse; therefore, some scholars have studied the use of laser transfer paper instead of conventi...
