Description
Technical Field
The invention belongs to the technical field of waterproof cloth, and particularly relates to a color-changing type electric aluminum hot stamping foil and a preparation method thereof.
Background
The printing and packaging technology is an important department of the light industry, along with the development of printing technology, the post-printing processing technology of printed matters is also improved rapidly, the printing technology is developed towards digitization, diversification and intellectualization, the living standard of substances of people is also increased in water, and higher expectations are provided for packaging, printing and decorating.
The electrochemical aluminum hot stamping foil is prepared by taking a biaxially oriented polyester film as a base material, sequentially coating a release layer, a coloring layer, an aluminum plating layer and a bonding layer on the surface of the base material, and then carrying out gradient high-temperature drying. The application field of the electric aluminum hot stamping foil relates to the aspects of anti-counterfeiting and identification of commodity packaging, surface finishing of plastic products, surface finishing of building material furniture, fabric transfer printing, trademarks, book covers and the like, and important certificate cards of art cultural goods, bank notes, visa, credit cards and the like.
The quality of the anodized aluminum stamping foil is mainly seen in peel strength and adhesion. The peeling strength is mainly determined by the release layer and the coloring layer, and is too small, so that the hot stamping layer is easy to transfer onto the hot stamping substrate, but is easy to paste and adhere. Too large peeling strength, the hot stamping layer of the electric aluminum hot stamping foil cannot be transferred or cannot be completely transferred to the hot stamping base material, and the problems of hot stamping sand holes, thin hot stamping patterns, low hot stamping speed and the like are easy to occur. The release layer made of vinyl silicone oil and isodecanol polyoxyethylene ether has the main problems that the peeling strength is too high, components for reducing the peeling strength are required to be added into the coloring layer, and the release layer made of non-sticky substances such as paraffin is too low, and components for enhancing the peeling strength are required to be added into the coloring layer. The adhesive force of the electrochemical aluminum stamping foil is reflected in the adhesive layer, and the electrochemical aluminum stamping foil is easy to fall off, not resistant to water washing and poor in durability due to low adhesive force. The current electric aluminum hot stamping foil has certain adhesive force, but needs to be improved.
