Abstract

The invention provides an aqueous binding agent which has washing resistance and is used for electrochemical aluminium hot stamping, and a preparation method thereof, belonging to a binding agent composition. The aqueous binding agent comprises 40-80 parts by weight of acrylic resin emulsion (with the solid content of 40-55%), 20-40 parts by weight of acrylic resin powder and 5-20 parts by weight of ethylene-vinyl acetate copolymer (EVA) emulsion (with the solid content of 40-60%). The binding agent does not contain organic volatile component, is harmless for the human body, is an environment-friendly electrochemical aluminium hot stamping binding agent, and is especially suitable for fabric which is needed to be printed and frequently washed.

Description

technical field [0001] The invention relates to a binder composition and a preparation method thereof, in particular to a washable water-based binder for anodized aluminum hot stamping and a preparation method thereof. Background technique [0002] Anodized aluminum hot stamping refers to the use of a certain pressure and temperature, using the template installed on the hot stamping machine, so that the printed matter and the hot stamping foil are pressed together in a short time, and the metal foil is transferred to the substrate according to the image and text of the hot stamping template. The craft of the print surface. The main material required for hot stamping is anodized aluminum foil, which has a metallic luster and is used for inscription patterns. The effect is better than that of ink-printed products, so it is widely used in hot stamping book covers, packaging decoration, product advertisements, product samples and calendars Postcards and other fine print. Anodi...
