Abstract
The invention discloses a deplating process for a vacuum electroplated film and relates to the technical field of vacuum electroplating processing on the surfaces of plastics, which aims at solving the technical insufficiencies of poor range precision, inconvenience to perform or incapability of realizing plating making operation on part of patterns or marks and the like of a conventional plating masking process. The deplating process comprises the following steps of: firstly printing out a pattern corresponding to a region to be reserved on the vacuum electroplated film through a screen printing screen; then baking printing ink of the pattern till dryness, then immersing into a deplating solution to remove the vacuum electroplated film outside the region corresponding to the pattern till the exposure of a subject matter, and then taking out; and finally spraying an intermediate coat and a finish coat. According to the deplating process disclosed by the invention, the vacuum plated film is manufactured on the subject matter by utilizing a traditional vacuum electroplating process, then the pattern is screen-printed on the vacuum plated film, the printing ink is baked and deplating is performed in the deplating solution; and furthermore, the deficiencies and the defects of the traditional electroplating technology are perfected, the vacuum plated film layer can be perfectly segmented and trimmed to achieve any required vacuum plated film effect, and the deplating process can be used for producing any precise patterns and mark effects.
Description
Technical field
The present invention relates to the plastic cement surface vacuum and electroplate processing technique field.
Background technology
Traditional vacuum plating manufacture field is being electroplated and is being added man-hour to the product appearance designated area, generally adopts tool to hide plating and handles, and hides the plating effect to reach.This kind hides depositing process and uses very extensively at present, but has the plating of screening transitional region to fly that oil, special construction can't hide plating, to hide the control of plating scope accurate inadequately, and especially hiding plating zone is pattern, indicates etc. to hide the depositing process complete operation.And promptly be that the traditional vacuum electroplating technology can only be realized large-area coating film; Zonal plated film also can only require lower thick mad formula to hide plating to transitional region; The perfect adaptation of coating film area and non-coating film area can't be reached, more the effect that plates out the pattern requirement can't be hidden.
Summary of the invention
In sum, the present invention exists the scope precision poor in order to solve existing screening depositing process, and part pattern or sign hide technical deficiencies such as plating operation inconvenience maybe can't realize, and a kind of vacuum plating film that proposes takes off depositing process.
For solving the technical problem that the present invention proposes; The technical scheme that adopts is: a kind of vacuum plating film takes off depositing process; It is characterized in that the said depositing process step that takes off is: at first, on the vacuum plating film, print out and the regional corresponding pattern that needs to keep through the silk-screen half tone; Then, after the printing-ink baking of treating pattern is done, immerse again and take off the vacuum plating film of removing in the plating bath beyond the pattern corresponding zone, take out after one's death until exposing research book; Coat with lacquer and finish paint in the spray at last.
Include as the present invention being made further improved technical scheme:
The employed printing ink of described printed patterns is PU printing ink.
Described baking printing ink adopts constant temperature roaster at 60 ℃ of baking 5 ~ 10min.
The employed printing ink of described printed patterns is light-curable ink.
Described baking printing ink adopts dull and stereotyped UV machine baking, UV energy 400 ~ 600mj/c ㎡.
The described plating bath that takes off is an acid attack solution, and when the vacuum plating film was zinc-plated, indium or indium stannum alloy, taking off the plating time was 3 ~ 5s; When the vacuum plating film when aluminizing, taking off the plating time is 10 ~ 12s.
Beneficial effect of the present invention is: utilize the traditional vacuum electroplating technology on material, to make vacuum plating; And then screen printing pattern in the vacuum plating, the printing ink baking is taken off and is taken off plating in the plating bath; The deficiency and the defective of traditional electrical coating technology that the present invention is perfect; Can vacuum coating perfectly be cut apart and pruning,, can be used for producing any accurate pattern and sign effect to reach needed any vacuum plating effect.
Embodiment
Below enumerate out specific embodiment of the present invention content of the present invention done explanation further:
The technology of general vacuum plating is on material, to spray one deck priming paint earlier, does plating again, and priming paint uses traditional U V photo-cured coating.Priming paint requires: good leveling property, and opacifying power is excellent, and strong adhesion because material is a plastic component, can steep by residual air when injection moulding, organic gas, and when placing, can suck airborne moisture.In addition, because frosting is smooth inadequately, the workpiece surface of Direct Electroplating is rough, and gloss is low, and the metal sense is poor, and undesirable conditions such as bubble, bubble can occur.Spray after one deck priming paint, can form the surface of a smooth, and stopped the generation of the bubble bubble of plastics existence itself, make galvanized effect be able to represent.It is the further processing after above-mentioned traditional vacuum electroplating technique forms the vacuum plating film that vacuum plating film of the present invention takes off depositing process; At first; On the vacuum plating film, print out and the regional corresponding pattern that needs to keep through the silk-screen half tone, the printing ink of printed patterns needs evenly to hide on the coatings surface; Then; The product integral body that prints is toasted; When the employed printing ink of described printed patterns was common single liquid or biliquid PU printing ink, baking printing ink adopted constant temperature roaster 60 ℃ of baking 5 ~ 10min (adjust according to the material material, yielding material can reduce temperature time expand).When using light-curable ink, baking printing ink adopts dull and stereotyped UV machine baking, UV energy 400 ~ 600mj/c ㎡ (yielding material can suitably reduce the baking Energy value under the prerequisite that UV dries); After the printing-ink baking of treating pattern is done; Immerse and take off the vacuum plating film of removing in the plating bath beyond the pattern corresponding zone, take out after one's death until exposing research book, taking off plating bath is acid attack solution; When the vacuum plating film was zinc-plated, indium or indium stannum alloy, taking off the plating time was 3 ~ 5s; When the vacuum plating film when aluminizing, taking off the plating time is 10 ~ 12s, remains in the coatings that is printed with printing ink, forms metal pattern or sign effect; Lacquer reaches international examination criteria with finish paint to reach surface physical properties in spraying traditionally more at last, and the full packing of examining.
