A kind of electroless aluminum bronzing product and its preparation process

Abstract

The invention relates to the technical field of printing gold stamping, in particular to a non-alumite gold stamping product and a preparation process thereof. The preparation process of the non-alumite gold stamping product comprises the following steps that A, a combination plate is prepared, specifically, a gold stamping plate and a laser nickel plate with graphics and text information being carved are subjected to alignment and laminating through high temperature resistant glue to prepare the combination plate; B, paper is coated, specifically, the position, needing gold stamping, of the paper is coated with thermoplastic light oil or high-reflectivity coating to prepare a coating layer; and C, coating and gold stamping are conducted, specifically, the combination plate prepared in the step A is subjected to lock up and put on a machine, the coating layer prepared in the step B is pressed and subjected to gold stamping, and the non-alumite gold stamping product is prepared. The graphics and text information of the laser nickel plate can be printed on the paper in a hot stamping mode under the condition of no alumite medium, various laser effects can be shown on the paper through one procedure, the production cost is low, durability is good, the customization period is short, safety and environmental friendliness are achieved, and the multi-batch and small-amount production requirements are met.

Description

technical field [0001] The invention relates to the technical field of printing hot stamping, in particular to an electroless aluminum hot stamping product and a preparation process thereof. Background technique [0002] Hot stamping is a printing and decoration process, which is to heat and apply foil to the metal printing plate, and emboss golden characters or patterns on the printed matter. With the rapid development of hot stamping foil and printing and packaging industries, the application of anodized aluminum hot stamping is increasing. more extensive. The traditional anodized aluminum hot stamping heats the anodized aluminum through the hot stamping plate, the peeling layer melts, and then the adhesive layer also melts. During embossing, the adhesive layer is bonded to the substrate, the colored layer is separated from the base layer of the polyester sheet, and the aluminized layer and The colored layer remains on the substrate. [0003] Anodized aluminum is the mai...

AI Technical Summary

Problems solved by technology

[0003] Anodized aluminum is the main material used in hot stamping, but there are many problems in using anodized aluminum for hot stamping: (1) the reuse rate of anodized aluminum is low, and the waste phenomenon in the production process of hot stamping is serious; (2) the manufacturing process of anodized aluminum can High consumption and serious pollution; (3) The quality of anodized aluminum directly affects the effect of hot stamping. Wrinkles, poor surface gloss, and blurred outlines of graphics and texts in anodized aluminum will directly lead to paste, reverse pull, and hot stamping failure of hot stamping products. The above problems affect the quality of bronzing products; (4) Anodized aluminum bronzing process has a single layer of anodized aluminum foil, and one bronzing process can only be stamped with one effect. If three kinds of laser effect patterns are required, three bronzing processes can be realized. It is impossible to achieve a variety of laser effects in one bronzing process; (5) The customization requirements of anodized aluminum are high, requiring large-scale customization, and the production and procurement cycle is long, resulting in high costs for small-batch and multi-batch production
