Abstract

The invention relates to laser paper printing ink and a preparation method thereof. The laser paper printing ink comprises the following ingredients (by weight): 15-20 parts of waterborne acrylic resin, 10-20 parts of waterborne polyurethane resin, 10-18 parts of dipropylene glycol diacrylate, 15-20 parts of a pigment, 6-10 parts of nanometer titanium dioxide, 2-4 parts of nano-zinc oxide, 8-10 parts of a filler, 14-20 parts of a reactive diluent, 3-5 parts of a photoinitiator, 1-3 parts of a photosensitizer, and 0.1-0.2 part of an auxiliary agent. The invention is beneficial for the ink to adhere to the surface of a printed material by the surface tension at the initial stage of drying; and in the drying process of the printing ink which is thoroughly adhered to the surface of the printedmaterial by solvent volatilization and penetration into the printed material, the formed net structure can make the solvent to be volatilized at a proper drying rate. In addition, due to high viscosity, cohesiveness of the printing ink penetrating through the printed material can be improved, and the color exposure problem is reduced.

Description

technical field [0001] The invention belongs to the technical field of packaging, and relates to a laser paper ink and a preparation method thereof. Background technique [0002] During paper making and processing, laser holographic patterns or characters are loaded onto the surface of aluminum-coated cardboard by molding to form laser paper. Laser paper consists of three parts: base paper, aluminum layer and coating. UV ink is one of the key elements of laser paper packaging printing. Its many physical and chemical properties, such as drying performance, optical properties, resistance performance and water content, have a great impact on the final quality of printed matter. Color exposure refers to the phenomenon that the colored layer attached to the surface of the printed matter is broken. This phenomenon is most likely to appear at the position of the beer line of the printed matter. It will not only affect the aesthetics of the printed matter, but also reduce the qual...
