Abstract

The invention discloses a PET sheet for UV curable decorative ink, comprising the following components by weight: 20%-45% of polyurethane acrylate resin or pure acrylic resin with polyfunctionality, 0-15% of a modified epoxy acrylate oligomer, 5%-20% of acrylic monomer with single functionality, 0-15% of acrylic monomer with bifunctionality or polyfunctionality, 0-20% of sand powder or effect powder, 5%-30% of a special effect resin powder, 0-5% of an adhesion promoter, 3%-5% of a photoinitiator, 0.1%-2% of a polymerization inhibitor, 0-20% of a filling agent and 0.2%-5% of an auxiliary agent. The ink provided by the invention has good stability, does not contain organic solvent residue, or have VOC residual or emit harmful gas, and is environmentally-friendly; and the ink cures fast and does not cause deformation of the PET sheet. The coating has concave convex matte layer formed on the PET surface, strong hand feeling and excellent alcohol resistance and water resistance. The method provided by the invention has the advantages of simpleness, high production efficiency and easiness for operation and promotion.

Description

technical field [0001] The invention relates to the technical field of chemical polymer materials, in particular to a UV decorative ink used for PET sheets and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) has excellent mechanical properties, high rigidity, high hardness, low water absorption, good dimensional stability, good toughness, impact resistance, friction resistance, creep resistance and chemical resistance Good and other characteristics. PET is widely used in the electronic and electrical industry, such as electrical casings, nameplate labels, instrument panels, insulating films and electrical product packaging. [0003] Screen printing inks developed for PET sheets are roughly divided into solvent-based inks, water-based inks and ultraviolet (UV) curable inks. In order to improve production efficiency, the curing process of solvent-based inks and water-based inks requires heat treatment, and the process of heat trea...
