Description
Technical field
The present invention relates to additive, particularly a kind of Efficient gravure additive for chrome-plating (also known as the efficient additive for chrome-plating of HIGH-05).
Background technology
Made chromium plating catalyzer with sulfuric acid since Two decades years and realize industrialization, this standard chrome-plated process is used till today always.But this chrome-plated process current efficiency is low, cathode efficiency, only up to about 13%, namely has the electric energy of about 87% to be wasted in chrome-plating process.For overcoming this disadvantage, be once developed into s-generation catalyzer-fluorochemical latter stage in the forties, occurred so-called " composite chrome plating " liquid, the current efficiency of this chromium plating liquid reaches as high as 25%, and all increases to the luminance brightness of coating and hardness; But this chromium plating liquid can cause low current place plating piece and chloride plate corrosion, and chromium plating liquid is more responsive to impurity.
In recent years, though the domestic rare earth addition promoting also has higher current efficiency, because it is fluorine-containing, corrosion can be caused in the not plated part of antianode stereotype and plating piece, so be still not suitable for hard chrome plating.
Along with the development of market economy, competition among enterprises is constantly fierce, and production cost and the quality of production seem more and more important, is also the important indicator weighing enterprise technology and level of management simultaneously.Particularly be used in the electronic engraving intaglio plate additive for chrome-plating in gravure plate-making field, because traditional additive for chrome-plating current efficiency in electroplating process is low, electric energy consumption waste thus production cost is remained high, and the problem making the quality of production can not be guaranteed because causing corrosion to plating piece in production process is day by day serious, therefore, a kind of current efficiency how is developed high and be the problem that urgently will solve at present to the free from corrosion additive for chrome-plating of plating piece.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the present invention is just to provide a kind of Efficient gravure additive for chrome-plating, effectively can solve that current efficiency is low, electric energy consumes high and plating piece had to the problem of corrosion.
The technical scheme that the present invention solves is, by 1,5-naphthalene disulfonic acid sodium salt 12-18kg, potassiumiodide 8-12kg, sodium methylene bis-naphthalene sulfonate 9-15 kg, sulfuric acid 0.4-0.6kg, alcohol 0.25-0.35kg, chromic anhydride 0.4-0.6kg and pure water 25-39kg make, during preparation, be in the pure water of 35-45 DEG C in temperature, add 1,5-naphthalene disulfonic acid sodium salt, be stirred to dissolving, add potassiumiodide, be stirred to dissolving, add sodium methylene bis-naphthalene sulfonate and stir 0.15-0.25 hour, add sulfuric acid to stir, then add alcohol and stir, then add chromic anhydride and stir.
Described pure water is EC(specific conductivity) pure water of=0.1-1.0us/cm; Described sulfuric acid is the sulfuric acid of mass concentration 98%; Described chromic anhydride is chromium trioxide [chromium (acid) acid anhydride].
The present invention has extraordinary effect as the effective catalyst of durionise, add the chromium plating liquid of additive of the present invention, current efficiency can reach 25% ~ 30%, and coating light is level and smooth, and the product luminance brightness of electroplating out than traditional plating solution improves 80%, improve wear resistance and the corrodibility 30% of coating, its advantage is that current efficiency is high, and sedimentation velocity is fast, and not fluoride, to plating piece and chloride plate corrosion-free, ensure electroplating quality.

Embodiment 3:
The present invention is made up, during preparation of 1,5-naphthalene disulfonic acid sodium salt 18kg, potassiumiodide 12kg, sodium methylene bis-naphthalene sulfonate 15 kg, sulfuric acid 0.6kg, alcohol 0.35kg, chromic anhydride 0.6kg and pure water 39kg, be in the pure water of 45 DEG C in temperature, add 1,5-naphthalene disulfonic acid sodium salt, be stirred to dissolving, add potassiumiodide, be stirred to dissolving, add sodium methylene bis-naphthalene sulfonate and stir 0.25 hour, add sulfuric acid and stir, add alcohol again to stir, then add chromic anhydride and stir.
Additive of the present invention is domestic at present in order to improve, the quality product of International Packaging printing industry gravure printing roller and the one innovation carried out, the shortcoming of conventional chromate treatments is that current efficiency is low, 8-10% can only be reached, namely plating solution has the electric energy of about 87% to be wasted in chrome-plating process, other electric current all becomes hydrogen in the reaction and runs off, and additive for chrome-plating in the market only plays current efficiency raising to intaglio plate chromium plating, improve and reach 13-17%, but antianode corrodes, current efficiency is not only brought up to 25% by additive for chrome-plating of the present invention, and do not corrode anode, and can covering power be improved, thus the chromium plating demand reached inside site, forme is enable to improve press resistance rate, because chromic acid in chromium plating liquid generally exists (H2Cr2O7) with dichromic acid form, dense chromium plating liquid can be that trichromic acid (H2Cr3O10) and tetrachromic acid (H2Cr4O13) form exist, when existing without catalyzer such as sulfuric acid when only having chromic acid in plating solution, pass into direct current, negative electrode only have hydrogen separate out, layers of chrome is not had to deposit, be equivalent to brine electrolysis, in fact be exactly there is no ionogen.Therefore catalyzer of how controlling well is crucial, the present invention be directed to additive and improves, finally improve the catalytic capability of catalyzer through overtesting, is no matter can to bring into play katalysis in high current zone and low current region.
The product using the chromium plating liquid of additive of the present invention and traditional chromium plating liquid to plate out is compared as follows:
Common chromium plating chromium ion arranging density is 300/centimetre, so will use the polishing of 600# sand paper, surface ion arrangement is changed into 600/centimetre, and improves surface smoothness.
Use HIGH-05 efficient additive for chrome-plating chromium plating chromium ion arranging density can reach 1000/centimetre, the polishing of 1000# sand paper can be used, because arranging density own is high, so there will not be band line of ink marker phenomenon, and the wearing and tearing decreased the space of a whole page, so no matter from quality, cost, should result of use all obviously to than common chromium-plating effect.
The product using the plating solution of additive of the present invention to plate out has significant change than the product using conventional chromate solution to plate out, and through experiment, Measurement and Computation, has following outstanding feature and marked improvement:
1), component science, consumption is reasonable, and be original creation in practice, for additive for chrome-plating, cathode efficiency is high, can reach 30%;
2), the careful light of coating crystallization, strong with basal body binding force, coating crackle coefficient is up to 1000, higher than common plating solution crackle 400 2.5 times; Making the more resistance to print of plating gravure, luminance brightness high, there is not falling chromium phenomenon in more than coating hardness HV1000;
3), improve environment protecting, make to pollute in electrodeposited chromium process to reduce;
4), the about 25000 degree/moon of saves energy consumption (1 coating bath), about 15000 yuan (0.6 yuan/degree), shortens electroplating time 1/3, increases work efficiency 1/3;
5), not containing fluorine element, antianode stereotype and plating piece not plated part can not produce corrosive nature;
6), sedimentation velocity is fast, and can reach higher current density and have higher current efficiency, sedimentation velocity can reach 3 ~ 6 μm/minute;
