Abstract
The invention provides a production technique for alkalinity zincate zinc-plating additive, wherein the hexamethylenetetramine is dissolved in the distilled water, in which the 2-thiol group benzimidazole is added, the chloroepoxy propane is added while stirring, the mixed liquid is heated up and refluxed for half an hour after the complete reaction. The invention has the advantages of simplifying ingredients of the bath, conveniently adjusting and controlling the bath for lowering cost and being applicable to the passivation of the low chromium, along with the environmental protection.
Description
Technical field
The present invention relates to a kind of technique for producing alkaline zincate galvanizing additive.
Background technology
At present, the key of alkaline zincate galvanizing is to choose appropriate additive, adds the organic additive in the electroplate liquid, must add polarization type, two kinds of additives of brightening type in zinc-plated production simultaneously.The composition complexity, the cost height has to pollute to produce, and is unfavorable for environmental protection.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of technique for producing alkaline zincate galvanizing additive is provided.
Technical scheme of the present invention is: a kind of technique for producing alkaline zincate galvanizing additive is characterized in that: (two) benzazole obtains aurora type additive between introducing 2-thiol group in the macromole of amine and epoxy chloropropane condensation.
The present invention has the following advantages: simplify solution composition, be convenient to the plating bath regulation and control and reduce cost, be suitable for low chromium passivating, help environmental protection.
Embodiment
Embodiment: a kind of technique for producing alkaline zincate galvanizing additive, get hexamethylenetetramine 70 grams and be dissolved in the 120-180 gram distilled water, add (two) benzazole 4-10 gram between the 2-thiol group, stir adding epoxy chloropropane 40ml, question response is back temperature rising reflux half an hour fully, gets final product.
