Abstract
The invention discloses a kind of intaglio plate additive for chrome-plating, is made up of by weight the following raw material：20 22 parts of xylene disulfonic acid sodium, 8 10 parts of sulfamic acid sodium, 8 10 parts of KI, 24 parts of ethanol, 57 parts of magnesia, 46 parts of sulfuric acid, 45 55 parts of distilled water.The present invention has extraordinary effect as the effective catalyst of plating hard chrome, add the chromium plating liquid of additive of the present invention, for current efficiency up to 25%~30%, coating is bright smooth, and 80% is improved than the product brightness that traditional plating solution is electroplated out, improve the wearability and corrosivity 30% of coating, current efficiency height is the advantage is that, deposition velocity is fast, and not fluoride, it is corrosion-free to plating piece and chloride plate, ensure electroplating quality.
Description
Technical field
The present invention relates to additive, specifically a kind of intaglio plate additive for chrome-plating.
Background technology
Done plating chrome catalysts with sulfuric acid since 20 years and realize industrialization, this standard chrome-plated process continue to use always to
It is modern.But the chrome-plated process current efficiency is low, and cathode efficiency is only up to 13% or so, i.e., there is 87% left side in chrome-plating process
Right electric energy is wasted.To overcome this disadvantage, second generation catalyst-fluoride was once developed into the forties latter stage, was occurred
So-called " composite chrome plating " liquid is crossed, the current efficiency of this chromium plating liquid reaches as high as 25%, and to the brightness and hardness of coating
All increase；But this chromium plating liquid can cause plating piece and chloride plate corrosion at low current, and chromium plating liquid is to impurity ratio
It is more sensitive.
In recent years, though the domestic rare earth addition in popularization also has higher current efficiency, because its is fluorine-containing, to anode lead
The not plated part of plate and plating piece can cause to corrode, so being still not suitable for hard chrome plating.
With the continuous development of market economy, competition among enterprises are constantly fierce, and production cost and the quality of production seem increasingly
It is important, while be also the important indicator for weighing enterprise technology and managerial skills.It is especially used in the electronics carving in gravure plate-making field
Carve intaglio plate additive for chrome-plating, due to traditional additive for chrome-plating, current efficiency is low in electroplating process, electric energy consumption waste from
And production cost is remained high, and because in production process to plating piece can caused by corrosion and cannot be guaranteed the quality of production
Problem getting worse, therefore, it is high and be to compel at present to the free from corrosion additive for chrome-plating of plating piece how to develop a kind of current efficiency
Highly necessary solve the problems, such as.
The content of the invention
The invention provides a kind of intaglio plate additive for chrome-plating, to solve above-mentioned technical problem.
A kind of intaglio plate additive for chrome-plating, it is made up of by weight the following raw material：Xylene disulfonic acid sodium 20-22 parts, amino sulphur
Sour sodium 8-10 parts, KI 8-10 parts, ethanol 2-4 parts, magnesia 5-7 parts, sulfuric acid 4-6 parts, distilled water 45-55 parts.
Preferably, a kind of intaglio plate additive for chrome-plating, it is made up of by weight the following raw material：20 parts of xylene disulfonic acid sodium, ammonia
8 parts of base sodium sulfonate, 8 parts of KI, 2 parts of ethanol, 5 parts of magnesia, 4 parts of sulfuric acid, 45 parts of distilled water.
Preferably, a kind of intaglio plate additive for chrome-plating, it is made up of by weight the following raw material：21 parts of xylene disulfonic acid sodium, ammonia
9 parts of base sodium sulfonate, 9 parts of KI, 3 parts of ethanol, 6 parts of magnesia, 5 parts of sulfuric acid, 50 parts of distilled water.
Preferably, a kind of intaglio plate additive for chrome-plating, it is made up of by weight the following raw material：22 parts of xylene disulfonic acid sodium, ammonia
10 parts of base sodium sulfonate, 10 parts of KI, 4 parts of ethanol, 7 parts of magnesia, 6 parts of sulfuric acid, 55 parts of distilled water.
Beneficial effects of the present invention：
The present invention has extraordinary effect as the effective catalyst of plating hard chrome, adds the chromium plating of additive of the present invention
Liquid, for current efficiency up to 25%~30%, coating is bright smooth, is improved than the product brightness that traditional plating solution is electroplated out
80%, the wearability and corrosivity 30% of coating are improved, the advantage is that current efficiency height, deposition velocity is fast, and without fluorination
Thing, it is corrosion-free to plating piece and chloride plate, ensure electroplating quality.
