More Information
Summary:The invention relates to the technical field of digital ink jet, in particular to the field of IPC C09D11, and more particularly relates to LED curing ink jet printing ink and a preparation method thereof. The invention relates to a cationic water-based ink which comprises the following components in percentage by weight: 15-60% of a cationic monomer, 15-60% of an acrylic monomer, 1-8% of a cationic initiator, 1-8% of a free radical initiator and the balance of auxiliary agents. A cationic monomer containing two aliphatic epoxy groups at two ends of a molecule is selected to be compounded with an acrylic monomer, so that the curing speed of a hybrid curing system can be effectively improved, and the polymerization inhibition effect is reduced, thereby meeting the printing speed requirement under LED curing; the weight ratio of the cationic monomer to the acrylic monomer is 1: (1-2), the adhesion performance and alcohol wiping resistance of the ink to the surface of a product can be further improved, and the c
