Abstract
The invention relates to an orchestral instrument surface treatment method. According to the invention, the surface of an orchestral instrument is subjected to a coating treatment by using cathodic electrophoretic varnish. With the method provided by the invention, a uniform film can be provided on a complicated orchestral instrument. Compared with traditional spraying and dipping processes, with the method, a more beautiful appearance can be obtained. Water-based electrophoretic paint is adopted, and volatile organic compound content is low. Therefore, the metal orchestral instrument coating method has the advantages of environment-friendliness and low cost.
Description
Technical field
The present invention relates to musical instrument manufacturing technology field, relate in particular to a kind of surface treatment method of orchestra.。
Background technology
Because the outward appearance of musical instrument needs exquisiteness attractive in appearance, its surface treatment effect is very crucial.Traditional hand pressure spray process, paint vehicle must dissolve with solvent or diluent, has caused environmental pollution, and musical instrument is complex-shaped, area is little, and hand spray workpiece painting rate has only 28%, and waste is serious.
Summary of the invention
The object of the present invention is to provide a kind of surface treatment method of orchestra, this method control is simple, operating restraint is wide, is applicable to the surface treatment of difform orchestra.Used coating property height, chemicals-resistant and solvent corrosion, utilization ratio can effectively reduce wastewater discharge greater than 95%.Resulting appearance of coat fineness, and be easy to safeguard.
The present invention adopts following technical scheme for achieving the above object:
A kind of surface treatment method of orchestra is characterized in that, comprises the steps:
1) preparation process of preparation ability cathode electrophoresis varnish
The former lacquer of vinylformic acid ability cathode electrophoresis is added the deionized water dilution, stir, the volume ratio of the former lacquer of described vinylformic acid ability cathode electrophoresis and deionized water is 1:5-7;
2) orchestra pre-treatment step
Orchestra to be filmed is cleaned through ultrasonic oscillation;
3) step of filming
The ability cathode electrophoresis varnish of step 1) preparation is put into electrophoresis chamber, will be through step 2) orchestra after handling puts into groove, adjusts voltage 70 ± 10v, and temperature 25-30 ℃, pH5.0-5.5, electrophoresis time 1-1.5min;
4) baking step
After the orchestra of filming that step 3) is obtained carries out three stage countercurrent rinsings, put into drying in oven, temperature 150-160 ℃.
As a further improvement on the present invention, the volume ratio of the former lacquer of vinylformic acid ability cathode electrophoresis and deionized water is 1:6 in the described step 1).
Principle of the present invention is: adopt ability cathode electrophoresis, i.e. and coating particle positively charged, orchestra is negative electrode, and coating particle deposits film forming at orchestra, and anode dissolution does not take place as negative electrode in orchestra, thereby orchestra surface and phosphatize phosphate coat are not destroyed.
Beneficial effect of the present invention:
Because the vinylformic acid ability cathode electrophoresis varnish taked of the present invention is present domestic advanced person's middle-grade coating, erosion resistance, wet-hot aging performance are good, and paint film has good physics and chemical protection performance behind the product electrophoresis.The surface treatment method of orchestra provided by the present invention has following advantage: coating property height, chemicals-resistant and solvent corrosion; Treatment process paint vehicle utilization ratio height (greater than 95%), wastewater discharge is low, and tank liquor control is simple.Method operating restraint of the present invention is wide, is widely used in different clients' working specification, can obtain high-quality outward appearance coating by simple maintenance.
To sum up, utilize present method can guarantee to obtain uniform paint film at complicated orchestra; With respect to traditional spraying paint and paint-dipping process, can obtain the outward appearance of more beautiful; The water-based electrocoating paint, content of volatile organic compound is low; Guarantee that metal orchestra coating method environmental protection and cost are low.
