preparation example Construction

[0013] The preparation method of the white film layer disclosed by the invention comprises: forming an aluminum layer on a substrate, and forming a zirconium-titanium oxide layer on the aluminum layer.

[0014] Preferably, the thickness of the zirconium titanium oxide layer is 0.2-0.5um.

[0015] The method disclosed in the present invention also includes performing pretreatment on the substrate before forming the aluminum layer. The preprocessing consists of 8.0 x 10 -2 -1.0×10 -2 Argon ion bombardment pretreatment is carried out under the environment of pa; the argon ion bombardment treatment method is: the air pressure is 1.0×10 -1 -3.0Pa, preferably 1.5×10 -1 -2Pa, bias voltage is 200-1200V, preferably 400-1000V, duty cycle is 20%-70%, preferably 30%-60%, more preferably 40%-50%, time is 5-20min, preferably 8-15min. The specific operation is well known in the art, such as putting the base material into the furnace, and adjusting each process parameter within the above...

Abstract

The invention discloses a white film and a preparation method thereof. The white film contains an aluminium layer and a titanium-zirconium oxide. The preparation method comprises the following steps: forming the aluminium layer on base material and then forming the titanium-zirconium oxide on the aluminium layer. The white film disclosed by the invention has high colorimetric value, uniform and stable color and good aging resistance and the problems of fading and the like can not caused, thus the white film is very suitable for the surface decoration of high-end electronic products.

Description

【Technical field】 [0001] The invention relates to a white film layer and a preparation method thereof, in particular to a white decorative film film layer and a preparation method thereof. 【Background technique】 [0002] At present, thin film decoration of electronic products has been widely used, and the colors of decorative films are also very rich, such as silver, golden yellow, rose, coffee, gun color, black, white, etc. Among them, in some occasions, the demand for white film is also high. very big. [0003] In the prior art, for the preparation of white decorative films, most of them are realized by paint spraying. The white film layer prepared by the method has a wide range of chromaticity value, convenient color matching, simple preparation method, easy realization and low cost. However, this method is more polluting and cannot meet the requirements of environmental protection. Moreover, the white film layer obtained by spraying paint is not wear-resistant, has po...
