Production and printing process for pearl white aluminum-foil paper

Abstract

The invention discloses a production and printing process for pearl white aluminum-foil paper. The production and printing process comprises the following steps that (1) a hot melt adhesive adheres toa PET film with an aluminum foil; 2) bright copper paper is compounded on the aluminum foil; 3) pressing fit is carried out through a high-temperature roller of an externally-arranged heater to obtain the aluminum-foil paper; 4) the press-fit aluminum-foil paper is wound; and (5) a golden layer is compounded on the aluminum surface of the aluminum-foil paper through a wet compounding machine, water-based paint and red-yellow paste are adopted on compound ink of the aluminum-foil paper, and glue adopted in the compounding process of the aluminum-foil paper is white latex; and a drying oven isadopted for drying in the compounding process of the aluminum-foil paper, and the drying oven comprises five temperature control areas, wherein the temperature of a first area of the temperature control areas is controlled at 60 + / - 10 DEG C, the temperature of a second area is controlled at 80 + / - 10 DEG C, the temperature of a third area is controlled at 110 + / - 10 DEG C, the temperature of a fourth area is controlled at 80 + / - 10 DEG C, and the temperature of a fifth area is controlled at 60 + / - 10 DEG C. According to the production and printing process, the situation that the surface temperature of an actual ink layer is higher than a pre-controlled temperature, so that the aluminum-foil paper is discolored after being printed, and the surface of the adhesive is skinned is avoided.

Description

technical field [0001] The invention relates to the field of production and printing technology of aluminum foil paper, in particular to a production and printing technology of pearl white aluminum foil paper. Background technique [0002] At present, when aluminum foil paper is printed, the surface of the coating film is prone to roughness, showing a concave-convex state like orange peel; the reasons include: the angle of the scraper is too low or inappropriate; the solid content of the coating is too high or the fluidity and water retention of the coating are poor; the drying speed too high. At present, the commonly used method is to adjust by reducing the drying speed, but the penetration, coagulation, polymerization, and oxidized conjunctiva of the dried coating on ordinary paper are the main forms of coating drying. The use of a lower drying speed makes the solvent retained in the coating not only fail to thicken the coating quickly, but in turn hinders the polymerizat...

Problems solved by technology

[0003] In view of the above problems, the present invention proposes a production and printing process of pearl white aluminum foil paper, which solves the problem that the existing production and printing process of pearl white aluminum foil paper still maintains the same drying temperature in the later stage of drying, so that the actual ink layer surface temperature If the temperature is higher than the pre-control, the color of the aluminum foil paper will change after printing, and the defect of skinning on the surface of the adhesive
