Abstract
The invention discloses a manufacturing method for blackening mobile phone shell. The manufacturing method comprises the procedures as follows: a stainless punch forming shell is adopted; the shell is polished or wiredrawn; the shell is placed on an ultrasonic clean line to be cleaned; the shell is placed in a vacuum furnace; high voltage source is used for argon-ion bombardment for the shell; an Ion plating method is used for depositing a pure metal layer on the surface of the shell; a magnetron sputtering method is used for depositing a middle transition layer on the bottom layer of the pure metal; the magnetron sputtering method is used for coating a hard black film on the middle transition layer; the shell is passivated and cooled; and a static protective film is stuck on the shell for package. The manufacturing method has the characteristics of green environmental protection and energy saving. The tone range of a black nano film is that L is equal to 35 to 39, a is equal to -0.3 or 0.5 and b is equal to 0 to 3. The manufacturing method also has strong bonding capacity which can be over 8H under the loading below 1000g, so the wear-resisting property and the service life of the stainless cell phone casing are greatly improved.
Description
Technical field
The present invention relates to a kind of the phone housing that uses in the daily life is being carried out black preparation method.
Background technology
Stainless steel is with its excellent antiseptic property and metal-like, and environmental protection is just becoming the first-selection of medium-to-high grade phone housing metallic substance.At present electrochemical treatment or electrophoretic process are adopted in the painted processing of stainless steel phone housing more,, do not meet the standard of the RoSH of European Union because the reaction soln of electrochemical treatment generally all contains harmful sexavalent chrome; The decorating film of electrophoretic process mostly is organism, has both covered the metalluster of stainless steel phone housing, and aesthetics is had a greatly reduced quality, again because its hardness has only 2H, antifraying property is poor, make phone housing with the mutual friction mutually of things such as pocket, coin in fade easily, influence attractive in appearance.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of phone housing black preparation method, can effectively solve existing phone housing adopts electrochemical treatment harmful, with adopt electrophoretic process and covered the metalluster of phone housing, because its hardness and antifraying property difference fade easily, influence problem attractive in appearance again.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of phone housing black preparation method, it is characterized in that adopting following steps:
(a) adopt stainless steel impact briquetting shell;
(b) shell is polished or wire drawing;
(c) shell is placed the ultrasonic cleaning line clean;
(d) shell is loaded in the vacuum furnace body, utilizes high-voltage power supply that shell is carried out argon ion bombardment and handle;
(e) method of employing ion plating is at shell surface deposition one deck pure metal bottom;
(f) adopt magnetically controlled sputter method, on the pure metal bottom, deposit intermediate layer;
(g) adopt magnetically controlled sputter method, on intermediate layer, cross the black dura mater;
(h) shell is carried out the passivation cooling;
(i) adopt the electrostatic protection film to carry out the pad pasting packing to shell.
Further, stainless steel employing condition of surface is 2B or BA among the step a.
Further, the intravital vacuum tightness of vacuum oven is 6 * 10 in the steps d
-3～7 * 10
-3
Further, high-voltage power supply adopts 600～1000V.
Further, the pure metal layer adopts titanium or chromium among the step e.
Further, intermediate layer adopts titanium nitride or chromium nitride among the step f.
Further, the black dura mater adopts titanium carbonitride or carbon chromium nitride in the step g.
Further, the electrostatic protection film adopts PE electrostatic protection film in the step I.
The present invention has following beneficial effect owing to adopted technique scheme:
(1) under vacuum environment, will cross the film ionization and deposit film forming dry type and cross membrane method at shell, have environmental protection and energy-conservation characteristics;
(2) the steady elegance of black nano rete color and luster, metal-like is strong, and tone range is wide, and its tone range is: L=35～39, a=-0.3～0.5, b=0～3;
(3) bonding force of black nano hard membrane layer is strong, and its hardness is issued to more than the 8H in 1000g load, has greatly strengthened the wear resisting property and the work-ing life of stainless steel phone housing;
(4) but in the painted preparation of the stainless steel casing of the present invention's widespread use and various stainless steel phone housings and other 3C Product and built-in part.
