Abstract
A disclosed technology for decorating the surface of a metal housing of an electronic product comprises the following steps: providing a metal base plate; performing first coating on the surface of the metal base plate and drying; performing screen printing on the firstly-coated surface of the metal base plate to form a needed decoration pattern, and drying; and coating the surface of the decoration pattern obtained through screen printing with a protective membrane. The technology employs specially-prepared printing ink and employs the screening printing technology for forming various needed exquisite patterns on the surface of the metal housing. The printing patterns obtained through the technology are exquisite and various. Because the printing ink is prepared specially, the printing ink possesses certain tensile property, and statuses such as falling off, being damaged and the like of a pattern formed on the metal surface cannot be caused by performing stamping, stretching and other operations on the metal product, the integrity of the pattern is effectively guaranteed, and after being used for a long time, the metal products still can keeps good surface pattern effect and does not cause falling off, being damaged and other statuses of the patterns.
Description
Technical field
The present invention relates to a kind of metal surface decoration technology, be mainly used in the incrustation processing of the metal shell of electronic products such as notebook computer shell, phone housing, TV face frame, TV base, display face frame, display base.
Background technology
Along with the development of electronic technology, the electronic products such as notebook computer, smart mobile phone, Household appliances more and more become requisite article in people's life, people not only require more and more higher for the performance of these electronic products, high performancely the outward appearance of electronic product is also had higher requirement meeting, have the dazzling smart mobile phone of a outward appearance or notebook computer is also the thing that is worth excitement for a lot of people simultaneously.In order to meet the more demands of user for product appearance, manufacturer has designed electronic product casing miscellaneous, and on electronic product casing, produce various pattern, its pattern processing mode mainly contains: 1. by paste the film with exquisite pattern on the shell of machine-shaping, although this kind of mode can arbitrarily obtain various patterns, but the pattern pasting is easy to wear, come off, service life is shorter, has lacked metal-like; 2. directly on electronic product casing, obtain pattern by the technique such as wire drawing, anodic oxidation, single but the technique such as wire drawing obtains types of patterns, not environmental protection, is difficult to meet client's multiple demand; 3. can obtain the pattern more, more exquisite, third dimension is stronger by surface printing process, and pattern can have sense of touch, but at present there are no silk-screen printing technique is used for to metal shell of electronic product incrustation, and the pattern that existing typography obtains is easy to depart from metal substrate in shell forming process or use procedure, thereby affect the outward appearance of electronic product; 4. another kind of conventional method is surperficial anode processing, and this kind of technique is also only limited to wire drawing, sandblast texts at present, can not get good decorative appearance, and technical process is comparatively complicated and have very large pollution, and cost of manufacture is higher.
Therefore, a kind of pattern that can obtain various finenesses, color and enrich, have sense of touch is provided, the incrustation treatment process that can reduce again electronic product casing cost of manufacture and environmental protection, becomes electronic product, especially the demand of metal material electronic product casing incrustation.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of metal shell of electronic product surface decoration tech, to obtain pattern not only fineness but also the firmly electronic product casing of being combined with metal substrate.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of metal shell of electronic product surface decoration tech, comprises the steps:
1) provide a metal substrate;
2) do primary coat on the surface of metal substrate and dry;
3) metallic substrate surfaces after primary coat is done serigraphy and is formed the decorative pattern the oven dry that need;
4) after serigraphy, diaphragm is covered on the surface at decorative pattern.
Preferably, before primary coat, first metal substrate is carried out surface clean and dried.
Preferably, metal substrate is carried out to surface clean and comprise de-oiling fat, washing, pickling/alkali cleaning, neutralization and polishing step.
Preferably, described silk-screen printing technique comprises according to the light of required design producing high-resolution paints the film, and light is painted the film and made half tone thus, selects mesh and thickness according to pattern or lines fineness, and described mesh is greater than 420 orders, and described thickness is greater than 10um; After half tone completes, the full-automatic or semi automatic screen printing machine of employing carries out presswork, and be greater than 60 times lens examination pattern flatness, saturation degree and whether have broken string, zigzag etc.; The product needed that wire mark completes is through the hyperthermia drying of 180 degree.
Preferably, the ink adopting in described silk-screen printing technique is nanoscalar uv or solution ink, and employing forms through resin and the auxiliary agent allotment of formulated.
Preferably, after diaphragm step is covered on surface, the metal substrate with serigraphy decorative pattern is carried out stamping to form default electronic product casing shape, then CNC engraving is carried out in area, corner that can not be stamping and be shaped.
Preferably, deburring processing is carried out in the trimming position after the shaping of CNC engraving.
Preferably, the trimming position after deburring is carried out primary coat and is dried.
Preferably, for guaranteeing attractive in appearancely can to do process consistent with surface color to housing periphery tangent plane, or trimming position need to be treated to the decorative pattern that arbitrary hue forms with coupling serigraphy according to client.
Preferably, described metal substrate is aluminium alloy base plate, stainless steel substrate or other metal substrate.
Pass through technique scheme, a kind of metal shell of electronic product surface decoration tech provided by the invention, it adopts the ink of formulated and forms various required exquisite patterns by silk-screen printing technique on the surface of metal shell, the printed patterns that this technique obtains is not only exquisite, variation, and because ink is that formulated forms, ink has certain tensile property, can be because of the punching press of metallic article after metal surface forms pattern, operations such as stretching and occur coming off, the situations such as breakage, effectively guarantee the integrality of pattern, and long-term use still can keep good picture on surface effect and can not come off and damaged etc., various treatment process compared to existing technology, this invention processes for the incrustation of electronic product metal shell the exterior quality that more can guarantee electronic product metal shell, more can meet client for the exquisiteness of electronic product decorative appearance, the requirement of variation and product materialization.
Detailed description of the invention
To the technical scheme in the embodiment of the present invention be clearly and completely described below.
Embodiment 1:
