Technical field
The present invention relates to crystal works field, be specifically related to the making method that the double-colored pattern crystal of a kind of inserted gold and silver is set a table.
Background technology
Along with the lifting of people's consuming capacity, crystal works more and more comes into the life of people.Crystal works a great variety, different modeling, it is common one that crystal is set a table, and more can promote value at crystal surface after gold-plated or silver.At crystal surface, gold-plated/silver is too dull merely, does not also have stereoeffect, and people wish that crystal surface can have the demand of meticulous pattern and abundant color more and more stronger.
Summary of the invention
Goal of the invention: for overcoming the deficiencies in the prior art, the object of the present invention is to provide the making method that the double-colored pattern crystal of a kind of inserted gold and silver is set a table, outer shroud crystal being set a table by embedded structure and inner core form obvious shade deviation, promote stereoscopic sensation and the ornamental value of crystal works simultaneously.
Technical scheme: the invention provides the making method that the double-colored pattern crystal of a kind of inserted gold and silver is set a table, comprise the following steps:
(1) crystal is processed into respectively inner core and the outer shroud being set in inner core outside;
(2) core surface sputters one deck bright copper;
(3) inner core side sputtering silverskin;
(4) in the silverskin surface-coated photoresist material that step (3) obtains, upper hanger, the front surface of coating photoresist material inner core and rear surface are exposed to carries out gold-plated in electroplate liquid, obtain gold-plated film;
(5) the gold-plated inner core that step (4) obtains is put into acetone, ultrasonic removing photoresist material, clean and dry;
(6) inner core is embedded on outer shroud.
Preferably, the thickness of the bright copper described in step (2) is 50nm.
Preferably, described in step (3), the thickness of silverskin is 2 ~ 5 μm.
Preferably, in step (4), the processing parameter of electrogilding is: the electrolytic solution of electrogilding comprises sulfurous acid gold 30 ~ 50g/L, 2-sulfo--5,5-T10 10 ~ 120g/L, succimide 10 ~ 50g/L, Tripotassium Citrate 10 ~ 40g/L, citric acid 40 ~ 100g/L, antimonypotassium tartrate 1 ~ 3g/L, polyoxyethylene glycol 0.5 ~ 2g/L, S-WAT 20 ~ 150g/L, γ-picolinic acid 2 ~ 10g/L, the pH of this electroplate liquid is 4.1 ~ 5.4, and current density is 0.5 ~ 1A/dm
2.
Preferably, described in step (4), the thickness of gold-plated film is 20 ~ 50 μm.
Preferably, in step (6) inner core and outer shroud inlay when coordinating between gap be 0.05 ~ 0.1mm.
Preferably, inner core Ring current distribution outside in step (1), the geometrical shape of inner core is for revolving oar shape, regular polygon or irregular shape.
Beneficial effect: compared with prior art the present invention has the following advantages: compared with prior art, the making method that the double-colored pattern crystal of a kind of inserted gold and silver provided by the invention is set a table, the structure of inlaying by arranging inner core and outer shroud promotes the three-dimensional contouring of setting a table, inner core side in pattern structure is silver-plated, front and rear surfaces is gold-plated respectively, can improve the stereo admiring of color and luster contrast gradient and goods of furniture for display rather than for use.This making method is simple and quick, reproducible.
