Description

Technical Field

[0001] The utility model relates to the technical field of transfer films, in particular to a production device for an imitation aluminum-plated mirror transfer film. Background Art

[0002] The heat transfer decoration process involves transferring the decorative pattern onto the surface of the building material being decorated by heating the heat transfer film once, creating a high-quality decorative film. During the heat transfer process, heat and pressure combine to separate the protective layer and the pattern layer from the polyester base, permanently bonding the entire decorative layer to the base material.

[0003] With the promotion and application of thermal transfer technology, the requirements for the decorative and aesthetic properties of transfer films are becoming increasingly higher. In particular, certain types of transfer films are required to have a high mirror-like metallic luster. Existing metallic luster thermal transfer films generally have defects such as a single hot stamping pattern and low gloss of the mirror color. Currently, the mirror silver effect layer is achieved through aluminum plating. Common processes include laser aluminum plating and aluminum washing. This process is complex and energy-intensive. The laser area is uncontrollable, resulting in waste of metal resources. Aluminum washing produces a large amount of wastewater, polluting the environment. The cost is also high. In addition, the aluminum powder tends to fall off and lose its gloss over time. For example, mirror gold (bright gold) appears to be a matte gold after aluminum plating and aluminum washing, which does not meet the requirements of mirror-like metallic luster.
