Abstract
The brightening agent consists of benzal acetone as host brightening agent, alkylphenol polyoxyethylene ether as carrier, methyl and propyl aniline as assistant and naphthyl sulfonate as dispersant. When used in sulfate zinc-plating, it can improve the dispersion degree obviously and raise the brightness of coating greatly.
Description
The present invention relates to the brightening agent of the zinc-plated usefulness of metal, or rather, is a kind of brightening agent that is used for metal wire is carried out sulfate zinc plating.
Existing metal wire mostly adopts sulfate zinc plating technology.And used brightening agent mostly is Sudan Gum-arabic or natural peach gum, but its gloss deficiency, and resource is few.Use gelatin such as gelatine (gelatin) or dextrin etc. instead, its coating does not work, and flavescence easily in depositing.After adding nitrogenous sulfocompound such as thiocarbamide, its coating is light inadequately still, and becomes ash in depositing easily.So the galvanized wire surface quality of China obviously is inferior to external like product for a long time.China Patent No. is that the conducting salt that 90110089.7 " a kind of process for brightly plating of zinc for metal wire " adopted is a Repone K, and it is zinc-plated that sylvite is used for metal wire, and its current efficiency is lower, and sedimentation velocity is slower, and from the prescription of its additive, cost is higher.So this technology should not be applied.
Purpose of the present invention just is to remedy the deficiencies in the prior art, and a kind of current efficiency height, sedimentation velocity is fast, glossiness the is good brightening agent that is used for metal wire is carried out sulfate zinc plating are provided.
The present invention is combined by main brightener, carrier brightening agent, bright auxiliary agent and dispersion agent.Its combination mechanism is as follows:
1, main brightener:
Should possess the aromatic aldehyde that is connected with hydrogen atom at carbonyl one end as effective main brightener, or directly be connected in the C6H5CHO on the aromatic ring, for example benzylideneacetone etc.Its molecular structure is:
On aromatic ring, connect carbonyl or sulfonation gene, can increase of the present invention water-soluble.
2, carrier brightening agent:
The selection of carrier brightening agent is crucial, and (active hydrogen OH) and the substituent of oxyethane are as the alkylphenol polyoxyethylene class to select in the Fatty Alcohol(C12-C14 and C12-C18) hydroxyl among the present invention.The total molecule structure is:
The hydrophilic group of carrier brightening agent is made up of ethers and hydroxyl, has only one based on the hydroxyl of molecule one end, so mainly strong (O-) bring into play hydrophilic effect, and the ether number of package is many more, wetting ability is just good more by ether.
3, bright auxiliary agent:
The light auxiliary agent is exactly in fact that current density is widened agent.Because under certain current density, can produce the resistanceization effect in the electrode process.Do not influence electrode process in the redox processes in order to make, it is bright auxiliary agent that the present invention adopts methyl, propylbenzene aminated compounds.Its molecular structure is:
(or Na, K)
(or Na, K)
The experiment proved that: above-mentioned three class materials have the effect of significantly widening current density.
4, dispersion agent:
The effect of dispersion agent is to make main brightener to be evenly distributed in electrode process, reduces the coating decortication and the foaming that are caused by the stress concentration of coating, guarantees quality of coating.The present invention is so that how basic sour sulphur salt series is made dispersion agent.Its molecular structure is:
SO wherein
3H is at different positions, NH
2In 1,2 positions.
Or
NaSO wherein
3And HSO
3At different positions.
NaSO wherein
3And HSO
3At different positions.
