Problems solved by technology

However, the preparation process of this coating is also complicated, and some fillers doped in the anti-fingerprint paint and anti-fingerprint oil also contain free formaldehyde, which is not conducive to environmental protection and human health.
Moreover, this kind of organic coating has poor wear resistance and is easy to wear after a period of use, so that the substrate is exposed, the corrosion resistance performance is greatly reduced and the appearance is affected
In addition, the use of anti-fingerprint oil will make the surface of the coating look greasy, greatly reducing the visual aesthetics

Embodiment Construction

[0016] see figure 1 , a coating member 10 according to a preferred embodiment of the present invention includes a substrate 11 and an anti-fingerprint layer 13 formed on the surface of the substrate 11 .

[0017] The base body 11 can be made of metallic or non-metallic materials. The metal material may include stainless steel, aluminum, aluminum alloy, copper, copper alloy and the like. The non-metallic material is mainly plastic. The base body 11 has a rough surface, which is directly combined with the anti-fingerprint layer 13 . The roughness of the rough surface is 0.1 to 0.2 μm.

[0018] Anti-fingerprint layer 13 is a nanoscale tin dioxide (SnO 2 ) layer, which can be made by vacuum sputtering, such as magnetron sputtering. The thickness of the anti-fingerprint layer 13 is below 2 microns (μm), preferably 0.1-0.5 μm. The anti-fingerprint layer 13 is directly formed on the rough surface of the substrate 11 and has strong bonding force with the substrate 11 . The anti...

Abstract

The invention provides a coated part and a manufacturing method of the coated part. The coated part comprises a basal body and an anti-fingerprint coating formed on the surface of the basal body, wherein the anti-fingerprint coating is a nano-sized tin dioxide coating and nano-sized protrusions are formed on the surface of the coating. The manufacturing method of the coated part comprises the following steps of: providing a basal body and forming an anti-fingerprint coating on the surface of the basal body by vacuum sputtering method, wherein the anti-fingerprint coating is a nano-sized tin dioxide coating and nano-sized protrusions are formed on the surface of the coating.

Description

technical field [0001] The invention relates to a film-coated part and a manufacturing method thereof, in particular to a film-coated part with an anti-fingerprint function and a manufacturing method of the film-coated part. Background technique [0002] In the traditional technology, the early anti-fingerprint treatment is generally used to form a chromate layer and a special resin layer on the galvanized layer of stainless steel. This method first needs to electroplate a layer of zinc on the stainless steel plate, then apply chromate treatment, and finally apply a layer of resin by rolling. The process is complicated and requires chromate treatment, which seriously pollutes the environment. higher cost. [0003] Therefore, in order to avoid pollution and reduce costs, people began to study new anti-fingerprint materials. At present, it is widely used in industry to spray a layer of organic chemical substances on the substrate, such as anti-fingerprint paint and anti-fing...
