Problems solved by technology

[0003] At present, the performance requirements of high-temperature and high-speed hot stamping process systems at home and abroad are different from those of flat ironing process systems. In the high-speed hot stamping process of round pressing and round pressing, due to the faster rolling speed of the roller, the pressure action mode changes from surface contact to line contact. After the vehicle speed is close to 100 m / min, the hot stamping contact time is shorter. Therefore, under the same pressure, the thermal conductivity and thermal sensitivity of the hot stamping material are required to be higher, and the peeling force of the anodized aluminum is required to be smaller and the hot stamping The temperature is lower and the adhesion is stronger. At present, the anodized aluminum foil suitable for the high-speed hot stamping process of round pressing is still in the initial research and development stage, and most of them have poor stability of hot stamping performance, mainly manifested in hot stamping adhesion and trimming bad sex

Embodiment 1

[0016] Figure 1 shows the anodized aluminum foil suitable for high-temperature and high-speed hot stamping without laser effect of the present invention, which includes PET base film 1, release layer 2, imaging layer 3, aluminum-coated layer 4 and adhesive layer 5 from bottom to top. Its preparation method is:

[0017] (1) On the PET base film, a 200-mesh printing roller is used to evenly coat a release layer with a certain release force. The formula of the release layer is emulsified water-based wax: absolute ethanol: deionized water 1:51:48, the wet coating amount is 5.5±0.5g / m 2 , the drying temperature is 140°C;

[0018] (2) On the release layer, use a printing roller with a mesh number of 200 to evenly coat an imaging layer that allows the aluminum plating layer to adhere. The formula of the imaging layer is aminoacrylic resin: methyl ethyl ketone: butyl ester: toner : Alkyd resin (Bangcure PET-308-11)=52.4 : 27 : 19 : 1 : 0.6, dry coating weight is 1.00±0.05 g / m 2 , t...

Abstract

The invention provides electrochemical aluminum foil suitable for high-temperature and high-speed hot stamping. The electrochemical aluminum foil comprises a carrier film, a release layer, an imaginglayer, an aluminized layer and a rubber layer. The imaging layer comprises melamine acrylice resin, butanone, butyl ester, colourment and alkyd resin, the imaging layer is printed through a plate roller with 200 meshes, and the dry coating quantity is (1.00+-0.05) g / m<2>. The rubber layer comprises nitrile butadiene rubber modified phenolic resin, modified polyurethane resin, modified vinyl acid resin, ethyl ester, methylbenzene and silicon dioxide, the rubber layer is printed through a plate roller with the 180 meshes, and the dry coating quantity is (1.15+-0.05) g / m<2>. The hot stamping adhesive force of the electrochemical aluminum foil is strong, stripping force is smaller than 3 g / inch, the hot stamping speed is 100 m / min or above, the stamping suitability, temperature resistance, rubber aluminum firmness and color aluminum firmness are all good, and the electrochemical aluminum foil is specially suitable for the high-temperature and high-speed circular-pressing and circular-stamping technique.

Description

technical field [0001] The invention relates to a transfer film, in particular to an anodized aluminum foil suitable for transfer printing and containing an aluminized layer, and more particularly to an anodized aluminum foil suitable for high-temperature and high-speed hot stamping. Background technique [0002] Anodized aluminum foil is a hot stamping material made by adding a layer of metal foil on a film substrate by coating and vacuum evaporation. Anodized aluminum foil generally includes a film substrate, a release layer, an imaging layer, an aluminum layer and an adhesive. Floor. Electrochemical aluminum foil has been used in the field of tobacco packaging for a long time due to its gorgeous appearance, bright color, dazzling crystal, and easy use. With the development and changes of my country's tobacco market, cigarette brands are gradually integrated, and the output of packaging materials for a single tobacco brand is increasing. High-speed hot stamping of flat sh...
