Abstract
The invention discloses an acid copper brightening agent which is made of distilled water, copper plating brightening agents, bis-(sodium sulfopropyl)-disulfide and polyethylene glycol, wherein the copper plating brighteners are 2-thioxo-benzimidazole and thiocarbamide; and distilled water, thiocarbamide, 2-thioxo-benzimidazole, bis-(sodium sulfopropyl)-disulfide and polyethylene glycol are 20,000, 3.2, 4.8, 43 and 15 parts by weight respectively. When the acid copper brightening agent is added into a copper plating trough, the lightness of an electroplated product is effectively improved, and the product quality is improved.
Description
Technical field
The present invention relates to a kind of sour copper brightening agent.
Background technology
Brightening agent is a kind of additive that obtains bright depth in the plating bath that is added on.It is optimum that brightening agent has good inside and outside lubricity and surface light, has good mutual solubility and non-stick property simultaneously, can improve the vividness and the luminance brightness of colour batch.Along with development of science and technology, brightening agent is also used in increasing industry and is come.
The interpolation of brightening agent all is to adopt separately to add in the prior art, obtains luminance brightness with this.Be not easy management but add brightening agent separately, tank liquor also often changes, the time regular meeting occur that a certain material is higher or on the low side, phenomenons such as burning appears in downgrade, coating easily, bright striped and surface irregularity.
Summary of the invention
The present invention is directed to the problem in the background technology, researched and developed a kind of sour copper brightening agent, purpose is: can directly be added in the copper plating groove, improve the quality of product.
Technical solution of the present invention:
A kind of sour copper brightening agent is characterized in that: said sour copper brightening agent starting material are zero(ppm) water, copper brightener, sodium polydithio-dipropyl sulfonate and polyoxyethylene glycol.
Said copper brightener is 2-sulfenyl benzoglyoxaline and thiocarbamide.
The weight proportion of said zero(ppm) water, thiocarbamide, 2-sulfenyl benzoglyoxaline, sodium polydithio-dipropyl sulfonate and polyoxyethylene glycol is 20000:3.2:4.8:43:15.
Beneficial effect of the present invention:
The present invention has added sour copper brightening agent in copper plating groove, effectively improved the luminance brightness of plated item, promotes the quality of product.
Embodiment
A kind of sour copper brightening agent, starting material comprise zero(ppm) water, copper brightener, sodium polydithio-dipropyl sulfonate and polyoxyethylene glycol.Said copper brightener is 2-sulfenyl benzoglyoxaline and thiocarbamide.
In 20 liters of zero(ppm) water, add thiocarbamide 3.2 grams, 2-sulfenyl benzoglyoxaline 4.8 grams, sodium polydithio-dipropyl sulfonate 43 grams, polyoxyethylene glycol 15 grams.
The configuration step of acid copper brightening agent is:
1, the preparation of thiocarbamide: fully stir with 50～55 ℃ hot water and load weighted 2-sulfenyl benzoglyoxaline, it is dissolved fully, leave standstill after 2 minutes and pour in the zero(ppm) water.
2, the preparation of 2-sulfenyl benzoglyoxaline: put into container with load weighted thiocarbamide, boiled 4～6 minutes, leave standstill after 2 minutes and pour in the zero(ppm) water.
3, the preparation of polydithio-dipropyl sulphur sodium: fully stir with 50～55 ℃ hot water and load weighted two sulphur that gather, it is dissolved fully, leave standstill after 2 minutes and pour in the zero(ppm) water.
4, the preparation of polyoxyethylene glycol: fully stir with 50～55 ℃ hot water and load weighted polyoxyethylene glycol, it is dissolved fully, leave standstill after 2 minutes and pour in the zero(ppm) water.
5, after four kinds of materials mix, fully stir, leave standstill after 36 hours and use.
Claims (3)
