Problems solved by technology

Compared with PVC materials, PVB coating materials have the advantages of being relatively friendly to the environment, recyclable, and brightly printed images. However, organic solvents are used as diluents in the coating preparation process, and a large amount of organic solvents are produced during the production of weak solvent materials. At the same time, the biggest disadvantage of this kind of weak solvent digital inkjet recording material is that it dries slowly, which is increasingly unable to meet the development of high-speed inkjet printers.

Abstract

The invention discloses a polyacrylate emulsion for a highlight eco-solvent digital ink-jet recording material. The polyacrylate emulsion comprises the following components in parts by mass: 40-80 parts of water, 0.2-6 parts of emulsifying agent, 20-50 parts of unsaturated ester monomers, 0.1-1 part of initiator, 0.5-5 parts of crosslinking agent and 0.1-1 part of pH modifier. The polyacrylate emulsion for the highlight eco-solvent digital ink-jet recording material is uniform in latex particle distribution, waterborne and environmentally-friendly and can be used as an eco-solvent ink absorbing coating; an image printed by the highlight eco-solvent digital ink-jet recording material is high in drying speed and has the color density consistent with that of a polyvinyl butyral system.

Description

technical field [0001] The invention belongs to the technical field of emulsion polymerization in organic synthesis, and in particular relates to a polyacrylate emulsion for high-gloss weak-solvent digital ink-jet recording materials and a preparation method thereof. Background technique [0002] Eco-solvent digital inkjet recording materials are environmentally friendly, high-definition inkjet printing materials that can be used outdoors and developed with the promotion of eco-solvent printers and eco-solvent inks in recent years. [0003] At present, there are two main types of weak solvent digital inkjet recording materials on the market, one is polyvinyl chloride (PVC) mesh cloth material, which does not need coating treatment, and directly uses the solvent solubility of a certain molecular weight PVC material to absorb and fix weak solvents Ink; the other is polyvinyl butyral (PVB) coating material, PVB is coated on the surface of a certain substrate, and the PVB coatin...
