Embodiment Construction

[0018] 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 .

[0019] 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 can be plastic or ceramic. 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 0.05-0.25 micron (μm). The roughness of the rough surface can be formed by sandblasting, laser etching or chemical etching.

[0020] The anti-fingerprint layer 13 is a transparent nanoscale polytetrafluoroethylene layer, which can be made by plasma-assisted deposition coating method. The thickness of the anti-fingerprint layer 13 is below 2 μm, preferably 0.1-0.5 μm. The anti-fingerprint layer 13 is...

Abstract

The invention provides a plated piece and a preparation method thereof. The plated piece comprises a matrix and a fingerprint resisting layer formed on the surface of the matrix, the combination surface of the matrix with the fingerprint resisting layer has a roughness of 0.05-0.25mun, the fingerprint resisting layer is a nano-polytetrafluoroethylne layer, and a micro-nano mastoid structure is formed on the surface of the fingerprint resisting layer. The preparation method of the plated piece comprises the following steps: 1, providing the matrix; 2, roughening one surface of the matrix to make the surface have the roughness of 0.05-0.25mun; and 3, depositing the fingerprint resisting layer on the matrix-roughened surface with a plasma assisted deposition plating process.

Description

technical field [0001] The invention relates to a film-coated part and a preparation method thereof, in particular to a film-coated part with an anti-fingerprint function and a preparation 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 or anti-fingerpri...
