Embodiment Construction
[0015] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0016] see figure 1 , a method for manufacturing a vacuum aluminized film button, comprising the following steps:
[0017] 1) Adopt optical-grade transparent PET plastic sheet, usually size: 200mm×275mm, thickness: 0.1-0.188mm; heat the PET plastic sheet to 60-80°C and keep it warm for 1 hour, mainly to remove the water vapor on the surface of the UV layer of the PET sheet.
[0018] 2) The heated plate is coated with high-purity aluminum film on the surface of the UV layer of the plate by vacuum magnetron sputtering, as a reflective film of button metal color, the purity of aluminum is generally higher than 99.9%, and the thickness of 50nm to 100nm High-quality vacuum aluminized film can ensure the brightness of the aluminum film.

Abstract
The invention discloses a method for manufacturing a vacuum aluminized button, comprising the following steps of: (1) removing water vapor on a hardened layer surface of a PET (Polyester) plastic board; (2) aluminizing the hardened layer surface of the PET plastic board in a manner of vacuum magnetron sputtering; (3) coating printing ink on an aluminized surface in the manner of silk screen printing; (4) drying the printing ink; and (5) after the printing ink is dried, placing the PET plastic board into a button die for molding by injection, and then trimming button edges to obtain the aluminized button. In the invention, the highly reflective aluminized layer is placed on the inner surface of the button and an aluminum film is not in direct contact with the outside world, therefore, the service life of the aluminized button can be greatly prolonged, and the attractive appearance of the aluminized button can be maintained for a long period of time.
Description
technical field [0001] The invention relates to a method for manufacturing a button, in particular to a method for manufacturing a vacuum aluminum-coated button. Background technique [0002] The existing vacuum aluminized film button includes an injection molding body, a vacuum aluminized film is arranged on the upper surface of the injection molded body, and a paint protection layer is arranged on the vacuum aluminized film. The paint protection layer of the existing vacuum aluminized film button is directly in contact with the outside world, and it is easy to fall off, so that the vacuum aluminized film is exposed to oxidation, loses the metal texture, and is not beautiful; at the same time, the exposed aluminum film is easily damaged by direct contact with the outside world, and the button Short service life. Contents of the invention [0003] In order to solve the technical problems in the known technology, the invention provides a method for manufacturing a vacuum a...
