Embodiment 1

[0025] On the PET film with a thickness of 12um coated with a layer of fluoride ion modified water-based wax release agent, coat a layer of epoxy modified and acrylic resin paint with 10% metal complex dye toner according to the color requirements (environment Oxygen-modified acrylic resin accounts for 90%), and the dry coating weight is 0.7g / m 2 , where the toner content is 0.07g / m 2 , after molding and aluminum plating, apply a bonding layer according to the ratio of 10% polyurethane hot melt adhesive, 1% nano-silica, 30% toluene, 50% methyl ethyl ketone, and 9% isopropanol. Cloth weight is 0.7g / m 2 . The anodized aluminum film belt produced according to this process has been tested by the printing factory's circular pressing process, and the effective bronzing speed can be stabilized at 90m / min for continuous operation.

Embodiment 2

[0027] On the PET film with a thickness of 14um coated with a layer of fluoride ion modified water-based wax release agent, coat a layer of epoxy modified and acrylic resin coating (environment) with 12% metal complex dye toner according to the color requirements. Oxygen-modified acrylic resin accounts for 88%), and the dry coating weight is 0.7g / m 2 , where the toner content is 0.084g / m 2 , after molding and aluminizing, apply a bonding layer according to the ratio of 20% polyurethane hot melt adhesive, 2% nano-silica, 40% toluene, 30% methyl ethyl ketone, and 8% isopropanol. Cloth weight is 0.9g / m 2 . The anodized aluminum film belt produced by this process has been tested by the printing factory's circular pressing process, and the effective bronzing speed can be stabilized at 110m / min for continuous operation.

Embodiment 3

[0029] On the PET film with a thickness of 18um coated with a layer of fluoride ion modified water-based wax release agent, then coat a layer of epoxy modified acrylic resin coating (environment) with 15% metal complex dye toner according to color requirements. Oxygen-modified acrylic resin accounts for 85%), and the dry coating weight is 0.8g / m 2 , where the toner content is 0.12g / m 2 , after molding and aluminizing, apply a bonding layer according to the ratio of 14.4% polyurethane hot melt adhesive, 1.6% nano-silica, 35% toluene, 44% methyl ethyl ketone, and 5% isopropanol. The cloth weight is 0.8g / m 2 . The anodized aluminum film belt produced by this process has been tested by the printing factory's round pressing process, and the effective bronzing speed can be stabilized at 120m / min for continuous work.

Abstract

The invention relates to novel alumite suitable for rotary gold stamping on ultraviolet (UV) glazing oil paper. The alumite comprises a basic film layer, a film release layer, an information layer, an aluminized layer and a bonding layer, wherein the information layer comprises the following material components in percentage by mass: 85 to 90 percent of epoxy modified acrylic resin and 10 to 15 percent of metal complex dye toner; and the bonding layer comprises the following material components in percentage by mass: 10 to 20 percent of thermoplastic polyurethane hot melt adhesive, 1 to 2 percent of nano silica, 30 to 40 percent of toluene, 30 to 50 percent of butanone and 5 to 15 percent of isopropanol. The alumite has the characteristics of high gold stamping efficiency, transfer efficiency and adhesion, clear image-text edge and the like, coating thickness is reduced by 40 to 50 percent compared with that of the common alumite, and heat-conducting property is higher; and compared with the common UV flat gold stamping alumite, the alumite has the advantages that effective gold stamping speed can be improved from 40 to 60m / min to 90 to 120m / min when the alumite is applied to rotary UV gold stamping, and an optimization effect is obvious.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a new type of anodized aluminum suitable for circular pressing and bronzing on UV varnish paper. Background technique [0002] Electrochemical aluminum hot stamping is a very important post-press processing technology in packaging printing. It is mainly hot stamping patterns, characters, and lines to highlight the product's ranking, trademark, and tag, and beautify the product, thereby improving the grade of the packaging product. The bronzing anodized aluminum with anti-counterfeiting information layer is more difficult to forge due to the complicated manufacturing process, so it can play an effective anti-counterfeiting role. UV varnish is often used for varnishing and decoration of plastic or carton outer packaging, which plays a role of beauty and even anti-counterfeiting. The combination of bronzing anodized aluminum and UV varnish will greatly improve the grade and anti-c...
