Embodiment 1

[0034]The film system structure and film system thickness used in embodiment 1 are the same as those of comparative example 1. Argon ions are added to assist deposition during the indium plating process. The flow of argon gas is 50 sccm. After the indium layer is plated, oxygen ions are added to bombard the indium layer for 10 minutes. The oxygen flow rate that feeds is 50sccm, and other technological processes are identical with comparative example 1. The prepared samples are marked as S9, S10, S11, and S12. The L*, a*, and b* values ​​of the samples before and after the high temperature and high humidity (85° C., 85% RH) test are shown in Table 3.

[0036]

[0037] Table 3 shows the results of L*, a*, b* values ​​and ΔE values ​​of the samples before and after the high temperature and high humidity test in Example 1. It can be seen from Table 3 that the ΔE value is between 1 and 1.5, and compared with Comparative Examples 1 and 2, the high-temperature an...

Abstract

The invention provides a preparing method for a high-temperature and high-humidity resisting golden film. The golden film comprises a metal layer arranged on a transparent substrate and further comprises a first titanic oxide layer and a second titanic oxide layer which are arranged on the two sides of the metal layer. The first titanic oxide layer is closer to the transparent substrate. The golden film further comprises a silicon oxide layer which is arranged on the other sides / the other side of the first titanic oxide layer and / or the second titanic oxide layer. The preparing method comprises the steps that various films are plated through evaporation coating equipment, argon is added in a coating cavity for deposition assisting during metal layer plating, and oxygen is added in the coating cavity after metal layer plating and before second titanic oxide layer plating so as to conduct bombarding treatment on the metal layer. According to the method, the density of the metal layer inthe golden film can be improved, the metal layer is passivated, and activity of the metal layer is reduced. Thus, the color changing problem of the prepared golden film under the high-temperature andhigh-humidity conditions can be greatly solved.

Description

technical field [0001] The invention relates to the field of film coating, in particular to a method for preparing a high-temperature and high-humidity resistant golden film. The method is mainly used in the field of preparation of cover plates and back covers of mobile phones, tablet computers, smart watches, and the like. Background technique [0002] The cover glass is the protective layer of the touch screen, and has a wide range of applications in consumer electronics, automotive central control screens, and industrial controls. The cover glass market has a large space and great growth potential. In 2015, the global cover glass shipment area was 33 million square meters, a year-on-year increase of 13%, and the market size was 10.17 billion US dollars. With the diversification of market demand, the cover glass not only plays a role in protecting the touch screen, but also has an increasingly prominent function of beautifying the decoration. In recent years, the smartph...
