Production method of high-gloss one-sided dual-color heat transfer anodized aluminum

Abstract

The invention discloses a production method of high-gloss one-sided dual-color heat transfer anodized aluminum, which comprises the processes of release coating, color layer coating, heating and drying, accurate aluminizing and adhesive layer curing. In the processes, anatase metal powder enabling the gloss of the anodized aluminum to be increased is added in a color layer for spraying, and ethyl acetate is added in the anatase metal powder to be used as a developing agent of color chromatographic fractionation. By adopting an anodized aluminum production technology, printing and gold blocking effects are greatly improved, and especially, gloss of thermoprinted characters, patterns and lines is greatly increased.

Description

[0001] technical field [0002] The invention relates to a production method of bronzing anodized aluminum for cigarette tipping paper in the field of cigarette material production, in particular to a production method of high-gloss single-sided two-color thermal transfer anodized aluminum. Background technique [0003] At present, there are various forms of domestic tipping paper manufacturing. In recent years, aluminum-coated tipping paper has developed rapidly, which mainly realizes aluminization of tipping paper through ironing or transfer methods. This process technology needs to use anodized aluminum to carry out hot stamping printing on the printed tipping paper. This technology is relatively complicated, and it is often prone to dull graphics, lines and single colors on the hot stamping tipping paper. [0004] With the domestic demand for high-end cigarettes increasing day by day, most of the domestic tipping paper production process uses anodized aluminum hot sta...

Problems solved by technology

[0005] The object of the present invention is to provide a high-gloss single-sided two-color heat-transfer anodized aluminum production method that overcomes the above-mentioned defects. Insufficient, that is, in the process of hot stamping anodized aluminum on tipping paper, the problem of insufficient glossiness of the pattern is likely to occur, and the glossiness of anodized aluminum is better improved at the source, thereby improving the glossiness of the hot stamped pattern and line. In addition , this high-gloss single-sided two-color heat transfer electrochemistry can make the hot stamping graphics and lines on the tipping paper present a gradient color during the process of hot stamping anodized aluminum, and the color change is regular, which not only enhances the aesthetic performance of the packaging , which enriches the color of the hot stamping pattern on the tipping paper, enhances the hot stamping process technology, and greatly improves the anti-counterfeiting performance of the product
