Abstract
The invention relates to preparation of a sylvite zinc-plating brightener, which is formed by dissolving and evenly mixing the following materials based on a certain ratio: C6H5COONa, C10H10O, RO(CH2CH2O)3SO3NH4, an NNO dispersant and the like. The brightener of the invention can obviously improve brightness and planeness of a plating layer.
Description
Technical field
The present invention relates to a kind of preparation of sylvite zinc-plating brightener, mainly discuss effect, ratio and the compound method of the various compositions of this brightening agent.
Background technology
For a long time, zinc-plated many employings is that sulfate zinc plating and prussiate are zinc-plated.Because environmental problem is more and more serious, rise the seventies in 20th century, extensively carries out cyanideless electro-plating, multiple galvanization liquid occurred.It is zinc-plated etc. to mainly contain sulfate zinc plating, chloride galvanizing, fluoroborate.Wherein, the potassium chloride type subacidity is zinc-plated is a kind of faster zincincation of development in recent years.Because the solution composition of this process using is simple, stable, the careful light of coating, the current efficiency height, ironcasting, high-carbon steel part, thermal treatment part are easy to plating, as long as additive is selected suitably, operating restraint can change between 5～45 ℃, adds that wastewater treatment is simple, environment is not almost polluted, thereby application surface is wider.
Summary of the invention
The present invention has invented a kind of sylvite zinc-plating brightener for the luminance brightness that improves zinc coating.
The present invention adopts C
6H
5COONa, C
10H
10O, RO (CH
2CH

3SO
3NH
4, material such as NNO diffusant forms the brightening agent of sylvite galvanized liquid.
Concrete preparation method of the present invention comprises the step of following order:
A. with the C of calculated amount
6H
5COONa pours in a small amount of hot water (90 ℃), stirs it is fully dissolved;
B. the NNO diffusant of calculated amount is poured into, stirring is fully dissolved it;
C. respectively with the C of calculated amount
10H
10O and RO (CH
2CH
2O)
3SO
3NH
4Slowly pour into, stir;
D. keep the temperature about 70 ℃ to stir more than the 24h, leave standstill the 24h after-filtration then.
A kind of sylvite zinc-plating brightener of gained of the present invention is the transparent liquid that is deep yellow.
Description of test
The present invention increases the content of brightening agent successively by carrying out sylvite galvanized experiment, and observes the coating luminance brightness, finds that brightening agent can obtain bright coating in 8～30mL/L scope.
Embodiment
The concrete preparation process of present embodiment is as follows:
A. prepare general Repone K galvanizing solution, and adjust pH value.
B. the brightening agent with calculated amount adds the Repone K galvanizing solution while stirring, makes its thorough mixing even.
C. adjust the plating bath pH value once more, make it within processing range.
D. respectively different brightening agents is carried out carrying out after zinc-plated the comparison of zinc coating luminance brightness.
Sylvite galvanized technical recipe is:
Zinc chloride (ZnCl
2) 60～70g/L
Repone K (KCl) 180～220g/L
Boric acid (H
3BO
3) 25～35g/L
Brightening agent 8～30mL/L
PH value 4.5～6
DK 1～3A/dm
2
10～50 ℃ of temperature
