Problems solved by technology

Therefore, the ink formulated with laser aluminum paste can only be used on the surface of smooth and transparent materials, and cannot be used on non-transparent materials, because only the transparent side can see the side that is arranged in parallel
In addition, because aluminum is not resistant to water and corrosion, laser aluminum paste cannot be used in water-based systems, and the acid value of ink resin is also very strict, which greatly limits the application occasions.
In addition, the disadvantage of the preparation method of the laser aluminum paste is that it is first coated with aluminum, and then laser molded on the aluminum film. Due to the hardness of the metal aluminum film, the molded nickel plate is greatly worn, and frequent production is required. Replace nickel plate, high production cost

Abstract

The invention relates to laser paste pigment with a 3D-effect and a preparation method thereof. The pigment is prepared from 15-35% of an alloy material, 65-85% of a dispersing agent, and 0-1.5% of anassistant. The preparation method comprises the following steps: (1) coating a resin layer with 1.5-2 mum of a thickness on a plastic film base material, preparing a laser information layer on resinby using a laser film pressure technology, and enabling the resin layer to form optical refraction points of different heights and sizes to obtain an information layer with a laser dream color effect;(2) enabling a multi-element alloy material to be deposited on the surface of the laser information layer by using a continuous winding magnetron sputtering method so as to form an alloy film with amagnetic conductance function in a nano thickness; (3) dissolving the resin by using a solvent, and enabling the alloy film to be separated from the base material; and (4) smashing and filtering mixedliquor prepared from the solvent, the resin and the alloy material, adding the assistant, and adjusting solid content, to obtain 3D-effect laser paste prepared from the solvent, the assistant and nano sheet-like alloy particles.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a 3D effect laser paste pigment and a manufacturing method thereof. Background technique [0002] Laser paste is a high-grade decorative and anti-counterfeit pigment that can produce different colors and laser colorful effects. It is a one-dimensional nano-sheet made of aluminum by using PVD technology, laser film pressure technology and other physical and chemical processes. After the particle slurry is printed with the laser ink prepared by it, the sheet-like particles are arranged on the printing substrate in a plane, relying on the special nanostructure on the surface of the particles to produce colorful discoloration effects through the refraction and reflection of light. [0003] CN201210105500.2 discloses a preparation method of laser aluminum paste. Its purpose is to provide a kind of plastic film as raw material, through vacuum aluminum plating, laser molding to produce lase...
