Description

The present invention relates to a metal surface covering structure, and more particularly to a metal surface covering structure capable of exhibiting a brilliant optical effect.

  In using a new generation of electronic products (especially portable products), being light, thin and compact is already a basic requirement for consumer products. Due to the high specific gravity of steel, in many cases, steel materials are parted and other lightweight materials are used. This is the main cause of the enormous popularity of engineering plastics over the past 15 years.

  Generally speaking, the majority of cases of electronic devices are manufactured using plastic materials for the purpose of weight reduction and for ease of production and manufacture. However, cases made of plastic materials are inferior in visual and tactile effects and texture. Therefore, the contractor should use a plastic electroplating method to create a metal layer on the plastic case to allow the plastic case to have a visual beauty and a better texture. Alternatively, a print or a seal layer is stuck on the plastic case by a pasting method to produce a metal texture. Other companies have developed a thermal spray method to form a metal layer on a plastic member. However, regardless of the method of thermal spraying, electroplating, pasting, etc., it is only possible to create a single metal texture on the plastic material, changing consumer's sensibility needs, electronic products As the competition in the market becomes fierce, simple metal textures such as simple gold and silver white cannot satisfy consumers' needs, and at the same time, the competitiveness in the consumer market is gradually lost. Will go.

  On the other hand, plastics are difficult to recycle, and major manufacturers in each country are beginning to adopt lighter materials on their products. Among them, the use of light metals is expanding day by day as the flow of energy conservation, weight reduction, and recycling for environmental protection is promoted. For example, aluminum alloys continue to develop significantly and magnesium, which is lighter than aluminum, is attracting great attention and expectations, and magnesium alloys are expected to eventually become one of the major structural materials. In other words, in addition to the previously used market, light metals are gradually being used in the fields of cars and energy products, and applications to new business opportunities such as 3C products and high-tech are progressing. Light metals are expected to become an important part of the metal industry.

  The current market needs for consumer electronics products are rapidly evolving, and in particular, the case of many electronic products is focused on the change of texture and color to attract consumers' attention. In general, the processing of magnesium alloy parts can be performed in the color desired by the customer even if the processing is performed by a conventional coating process. However, the metal texture cannot be produced in the baking process. In addition, some manufacturers apply a metal layer on case parts by electroplating, thereby giving the case a metal color, and then printing on the product to coat a special film layer with a pattern. be able to. However, the above-described processes / methods have only a single effect, and problems such as low process yield and poor adhesion of the film layer on the product occur.

  In light of the shortcomings when the above-mentioned conventional structural devices are actually used, the inventor has personally engaged in related industries, gained many years of experience in development, and concentrated on research. We propose a structure that effectively improves the above-mentioned problems with a dynamic design.

  The main purpose of the present invention is to give metallic luster to the appearance of metal parts, and also to diversify the appearance of electronic products by giving three-dimensional and brilliant color changes such as font and design. An object of the present invention is to provide a metal surface covering structure capable of meeting the demand.

Another object of the present invention is that it can be used for product cases or related parts, and its appearance has a special color change effect, and the color can be changed according to the viewer's angle change. The object is to provide a metal surface covering structure capable of creating a visual effect of changing.

  In order to achieve the above object, the metal surface covering structure provided by the present invention includes a metal bottom material, a primer layer installed on the metal bottom material, a metal plating film layer installed on the primer layer, and the metal A transparent coating layer is provided on the plating film layer, and the metal plating film layer has at least one pattern, and a surface of the metal plating film layer has an uneven microstructure.

  As in the structure described above, the metal plating film layer may have a metal texture. Furthermore, the uneven microstructure (for example, wrinkles) on the surface of the metal plating film layer can give a three-dimensional and brilliant color texture of the metal, so that the metal surface covering structure is more excellent in optical properties. Can have an effect.

The primer layer 11 preferably has high adhesion and can achieve excellent case characteristics of an electronic product.

  The metal plating film layer 12 is formed on the primer layer 11. In other words, after the metal bottom material 10 covers the primer layer 11, the metal plating film layer 12 can be formed by sputtering. The metal plating film layer 12 is manufactured by a vacuum plating film method. The actual sputtering process may include, but is not limited to, planar bipolar sputtering, tripolar sputtering, magnetically controlled sputtering, reactive sputtering, RF sputtering, or the like.

  Further, as shown in FIGS. 2 and 4, the transparent coating layer 13 can be formed on the metal plating film layer 12 to cover the metal plating film layer 12 and the pattern 121. The transparent coating layer 13 can be a protective layer, and the translucency of the transparent coating layer 13 can allow a user to observe the metal texture of the metal plating film layer 12. In this embodiment, the transparent coating layer 13 is formed by a spray method. According to the present invention, the uneven structure 122 can be formed on the surface of the metal plating film layer 12 by adjusting the parameters of the metal plating film, laser engraving, and spray method. For example, the microstructure 122 may be a wrinkle-type microstructure, and the microstructure 122 may have a brilliant color optical effect. Further, by combining the laser engraving pattern 121, a general consumer can appreciate the three-dimensional and brilliant color texture of the microstructure 122 by the transparent coating layer 13. In other words, the wrinkle-like microstructure can generate reflected light with different angles by irradiating the reflection surface with different angles. The wrinkled microstructure can have different color changes at different angles, and the wrinkled microstructure can have a brilliant color visual effect.
