Abstract

The invention provides an ultraviolet curing anti-anodic oxidation shielding protection printing ink, by taking total weight of a printing ink composition as a reference, the ultraviolet curing anti-anodic oxidation shielding protection printing ink comprises the following components by weight percentage: 55-80% of low polymer, 5-15% of active monomer, 3-8 parts of initiator and 15-25% of filling material; wherein the low polymer is one or two selected from aliphatic polyurethane acrylate and acid anhydride-modified epoxy acrylate. The ultraviolet curing anti-anodic oxidation shielding protection printing ink has the advantages of fast solidification speed, better adhesive force, CNC resistance, scratch resistance, immersion resistance by various cutting fluids, anodic oxidation resistance, easy stripping, no residues after film-stripping, and no base material corrosion; is suitable for aluminum material or aluminum alloy base material and plastic cement base material, and is especially suitable for an aluminum material and plastic cement-embedded composite base material.

Description

technical field [0001] The invention relates to the technical field of surface protection ink products, in particular to an ultraviolet light-cured anti-anode shielding protection ink, which is especially suitable for composite substrates inlaid with aluminum and plastic. Background technique [0002] Ultraviolet light curing ink, also known as UV ink, is a rapidly developing green and environmentally friendly ink. Compared with traditional inks, it has instant curing, no volatile organic solvents, high production efficiency, strong film forming hardness, and solvent resistance. Good, less environmental pollution, energy saving, etc., because of its incomparable advantages over traditional solvent-based inks, it has been widely used in many fields such as cigarette packs, wine packs, cosmetic packaging, pharmaceutical packaging, and self-adhesive trademarks. [0003] Today, more and more products (such as mobile phone casings, tablet computers, etc.) are designed with metal,...
