Abstract

The invention discloses an ultraviolet full-shielding printing ink and a preparation method thereof. The ultraviolet full-shielding printing ink is prepared from the following components in parts by weight: 40-60 parts of epoxy modified polyurethane acrylate, 10-30 parts of polyurethane acrylate, 10-30 parts of active monomer, 30-35 parts of filler, 0.5-1.0 part of pigment, 0.5-1.0 part of auxiliaries and 3-5 parts of photoinitiator; and the epoxy modified polyurethane acrylate is prepared from the following components in parts by weight: 60-80 parts of epoxy modified polyurethane prepolymer, 10-30 parts of acrylic acid monomer and 0.8-1 part of polymerization inhibitor, wherein the epoxy modified polyurethane prepolymer is prepared from the following components in parts by weight: 15-20 part of epoxy resin, 40-60 parts of dihydric alcohol and 25-30 parts of isocyanate. The ultraviolet full-shielding printing ink disclosed by the invention forms a protective oil film on the surface of a workpiece after being cured by UV, so that the surface of the workpiece is prevented from being scratched and pinched and corroded by cooling liquid, then the cooling liquid can be easily eliminated, no trace is left, and a mirror surface effect is not destroyed.

Description

technical field [0001] The invention relates to inks, in particular to UV full-shielding inks. [0002] The present invention also relates to a preparation method of the above-mentioned ultraviolet full-shading ink. Background technique [0003] For stainless steel, aluminum-magnesium alloy mobile phone shells, or other metal components, in order to implement a series of mechanical precision machining, the metal shell (or metal components) must be packed into an accurately positioned steel body with multi-point mechanical clamping In the jig, CNC machining is performed on the workpiece. Since the workpiece is mechanically clamped and affected by the cutting force of the tool, and the workpiece is held, pinched, moved, and pressed by the operator, it is inevitable to be bruised and scratched, especially the workpiece has been processed. Without mirror polishing treatment, such slight damage is absolutely not allowed. In the previous remedial measures, the only way was to p...
