Problems solved by technology
[0004] The purpose of the present invention is to provide a production method of bronzing anodized aluminum, which solves the environmental protection problem of anodized aluminum as a bronzing material for cigarette tipping paper, and uses water-soluble inks in all procedures of anodized aluminum production, that is, uses water-soluble glue, water-soluble Non-toxic glue layer, water-soluble varnish production, no volatile toxic organic solvents, harmless to people, no pollution to the atmosphere, non-flammable and explosive, improving the environment and conducive to safety, thus realizing benzene-free environmental protection production in a true sense Anodized aluminum material
The anodized aluminum produced by this method solves the shortcomings of low water-based ink manufacturing anodized aluminum bronzing temperature, unstable aluminum ink color, low brightness, poor tinting strength, poor post-press adhesion, slow drying speed, and poor water resistance.
[0005] The invention also solves the problem that water-based anodized aluminum and alcohol-soluble tipping paper bronzing are not applicable

Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0025] As shown in the accompanying drawings: a production method of bronzing anodized aluminum, comprising the following steps:
[0026] 7) choose the PET polyester original film as the base layer;
[0027] 8) Use a water-based release material to coat and dry the base layer to form a release layer;
[0028] 9) Use water-based varnish on the release layer to coat and dry to form a protective layer;
[0029] 10) Use water-based blending pigments on the protective layer to coat and dry to form a pigment layer;
[0030] 11) Vacuum aluminum plating on the pigment layer, that is, the film coated with the color layer, etc., is placed in the vacuum chamber of the continuous aluminum coating machine, and the aluminum wire is melted and continuously evaporated to the pigment of the film by resistance heating under a certain vacuum degree On the layer, an ...

Abstract
The invention discloses a production method of hot stamping foil, which adopts six production process flows: release coating, protective layer coating, color layer coating, accurate aluminizing and curing glue layer coating. In the whole production process, water soluble glue, water soluble ink and water soluble gloss oil are used to realize the integrated production of the hot stamping foil, methacrylates and monomers which are emulsified and polymerized are mixed in a certain ratio, a dye leveler, thickener and the like are added in the mixture, the resulting product is coated and dried, polyvinyl butyral-based glue is coated, and the whole production of the hot stamping foil is finished. The hot stamping foil produced by the process has the characteristics of energy conservation, environmental protection and sanitation.
Description
technical field [0001] The invention relates to a production method of anodized aluminum in the field of cigarette material production, in particular to a production method of bronzing anodized aluminum. Background technique [0002] At present, the domestic anodized aluminum production mainly uses solvent-based coatings, that is, the inks used in various procedures for the production of anodized aluminum are made of organic solvent fiber resins, ethylene vinyl acetate resins, ketone resins, pigments, etc. to form release layers and color layers. , Adhesive layer solvent ink. The electrochemical aluminum has a mature production process, stable performance, and wide applicability, but the electrochemical aluminum contains benzene, which has a strong pungent smell, is flammable and explosive during the production process, and contains harmful substances that pollute people and packaging. Environmental performance is poor. [0003] At present, the more environmentally friendl...
