Abstract

The invention discloses printing ink concentration increasing technology for plastic printing. The technology comprises: S1, selecting materials; S2, matching raw materials, which include 30 parts ofa mixed solvent with the ratio of terpineol to diglycol being 3:1, 24 parts of a polyketone high-hydroxyl resin, 22 parts of pigment, 4 parts of an auxiliary agent, and 4 parts of a thickening agent for later use; S3, preparing a thickening agent; S4, preparing color paste; S5, preparing a solution; and S6 mixing solutions obtained from S4 and S5, adding an antifoaming agent, and performing uniform mixing. The technology has an obvious thickening effect. The thixotropic property of a printing ink can be significantly improved, and the emulsion thickener has bright application prospects in theink field.

Description

technical field [0001] The invention belongs to the technical field of ink thickening, and more specifically relates to a plastic printing ink concentration thickening process. Background technique [0002] Plastics include plastic films and plastic products. Plastic film printing includes plate making, blow molding, corona treatment, printing, compounding, slitting, heat sealing, bag making and other processes. Plastic product printing includes plate making flame treatment printing, etc., plastic printing substrates It is a plastic film and plastic product. Its molecular structure contains polar substances, has good chemical stability, and is resistant to corrosion by most acids and alkalis. It is insoluble in common solvents at room temperature, and antioxidants are added during the production process. Due to the poor affinity between the plastic substrate and the ink, the ink is not easy to dry after printing. At the same time, the plastic substrate does not have the po...
