Improved type evaporation groove of rainbow film electroplating technology

Abstract

The invention discloses an improved type evaporation groove of a rainbow film electroplating technology. The improved type evaporation groove of the rainbow film electroplating technology comprises anevaporation groove and a cover plate covering the top end of the evaporation groove. Two rows of first copper column electrodes and second copper column electrodes are fixedly installed uniformly ina spaced manner on the two side walls inside the evaporation groove. A molybdenum boat is placed between each set of first copper column electrode and second copper column electrode, and each molybdenum boat is distributed between the corresponding first copper column electrode and the corresponding second copper column electrode in a spaced manner. Electrode connecting heads are formed respectively on the two sides of each molybdenum boat. Conductive connection is conducted through placement of copper pieces between each first copper column electrode, each second copper column electrode and the corresponding electrode connecting heads. Multiple target materials are tightly arranged on each molybdenum boat correspondingly. The lower end of each molybdenum boat is also cushioned with an upper supporting cushion block and a lower supporting cushion block, and both the upper supporting cushion blocks and the lower supporting cushion blocks are insulated cushion blocks. The evaporation groove assembly provided is matched with a vacuum evaporation plating technology, and the processing technological process of the transparent reflective rainbow film can be achieved.

Description

technical field [0001] The invention relates to the technical field of electroplating evaporation tanks, in particular to an improved evaporation tank for the magic color film electroplating process. Background technique [0002] For ordinary iridescent films, two or more transparent thermoplastic resins with different refractive indices (refractive index difference of at least 0.03) are usually combined to form at least 30 layers of uniform parallel films through ABABAB... or ABCABCABC... Alternate the core layer, on the outside of the core layer, attach the two skin layers with a thickness of 5-50% of the total thickness of the film, and then cast it on the cooling roller to form a film with a thickness of 0.015-0.05mm. When the thickness of the film reaches a certain range, due to light The role of interference, the film will produce a colorful rainbow-like effect. However, the strength of the existing iridescent film formed by using multi-layer resin is not high, and it...
