Abstract
The invention provides an etching process for stainless steel, which comprises a plurality of steps: a. pre-processing, used to do surface cleaning operations like cleaning and deoiling of the initial stainless steel workpiece; b. coating, in which the surface of the stainless steel is applied with photosensitive glue, and the operations of exposure, development and hardening are conducted; c. etching, in which stainless steel etching solution is used to erode the exposed metal part of the stainless steel workpiece; wherein, the stainless steel etching solution is mainly composed of: ferric trichloride 400 to 600 g/L, hydrochloric acid 2 to 5 g/L, ammonium bifluoride 1 to 2 g/L, thioureas 2.5 to 5 g/L, etching promoter 1 to 5 g/L and regenerator 2 to 5 g/L; d. demoulding, when the etching is done to a certain extent, the remaining glue on the surface of the workpiece can be removed by means of dissolving liquid, and thus the intended product can be obtained after cleaning. The invention has the advantages of good etching speed, high precision, regenerating capacity of the etching solution, simple manufacturing process and broad market prospect.
Description
Technical field
The present invention relates to a kind of metal surface treatment process, particularly relate to a kind of surface treatment technique for stainless steel.
Background technology
Stainless steel has hardness height, wear-resisting, good stability, shock-resistant characteristic such as strong, and the product that stainless steel obtains through etching does not have the rim stress of machinery processing, obtained using widely, particularly aspect ornamental label and shell, used wider at aspects such as national defence, electronics, electrical equipment.But,, limited the application of stainless steel etching and processing product because stainless high rigidity and high stability do not react or react too slow with strong acid and strong base.
Summary of the invention
In view of above problem, main purpose of the present invention is to provide a kind of stainless steel etching solution, and this solution processing procedure is simple, and etching speed is fast.
For achieving the above object, stainless steel etching solution provided by the invention, it mainly comprises following component:

Wherein, described etching promotor is preferably hydrogen peroxide; Described regenerator is preferably hypochlorous acid; Described thiocarbamide is as inhibiter and anti-lateral erosion agent.
In addition, another object of the present invention then is to provide a kind of stainless steel etching technique, and its technology is simple, and is easy to operate.
Chemical milling is to utilize the corrosive nature of chemical solution that unwanted metal is dissolved the process of removing fast by chemical reaction.
This kind stainless steel etching technique provided by the invention, its step is as follows substantially:
1. pre-treatment, it mainly comprises steps such as degreasing, activation, it is in order to clean initial stainless steel work-piece, to remove the wet goods cleaning surfaces;
2. coating, this step can comprise steps such as making luxuriant and rich with fragrance continuous heavy rain, exposure imaging, making web plate, silk-screen, and, carry out the exposure of photoresists according to the processing pattern more normally with its surface-coated photoresists of the stainless steel work-piece after the above-mentioned processing, then develop and the post bake processing;
3. etching, the exposing metal position that utilizes the stainless steel etching solution of above-mentioned preparation to corrode this stainless steel work-piece;
4. demoulding is treated above-mentioned eroding to a certain degree, its surperficial remaining glued membrane is removed with lysate again, and last water cleans up and obtains etching and processing workpiece product.
Therefore, stainless steel etching technique provided by the invention merges stainless activation and etching and carries out, make technology become simpler, in addition, in the stainless steel etching solution, add etching promotor, to accelerate etching speed, cooperate again simultaneously and add suitable inhibiter and anti-lateral erosion agent, improve precision, add regenerator again, make this etching solution repeatedly to use.Thus, it is fast that this technology has etching speed, the precision height, and characteristics such as etching solution is renewable, and processing procedure is simple are with a wide range of applications.
