Definitions
- This invention pertains to improvements in the electrodeposition of bright zinc from aqueous acid plating baths.
- Acid zinc electroplating baths are not new in the plating field and have, in fact, been used with moderate success for quite some time. Prior to this invention, however, certain limitations have in many instances rendered the existing acid zinc plating bath compositions extremely impractical to use and quite often not applicable at all.
- Another problem that has been common has been the lack of ductility in the zinc plate obtained from existing acid zinc bath compositions. Many parts are bent or shaped after plating either through manufacturing processes or through normal use. If the electrodeposit is not reasonably ductile, chipping, flaking and peeling of the plate can occur, thus causing rejection of the part.
- This invention comprises an aqueous, acid electroplating bath, for producing a bright, lustrous electrodeposit of zinc containing zinc ions and chloride ions, and dissolved therein, naphthol polyoxyalkylate having the formula:
- R is hydrogen or methyl, and x is about 8 to 20.
- polyethylenimine having the formula:
- R is hydrogen, methyl, ethyl, propyl, hydroxyethyl, Z-hydroxypropyl, 3-hydroxypropyl, 2- aminoethyl, 2-aminopropyl, or 3-aminopropyl, and y is about 10 to 20.
- the present invention is also an addition agent for an acid zinc electroplating bath consisting of from about 1:100 to :1 parts by weight of naphthol polyoxyalkylate and polyethylenimine of the above formulas.
- a general purpose bath was made up which contained 30 gms. ZnCl /liter and 200 gms. NH,Cl/liter at a pH of 4.9.
- the current density area from 0 to about 50 amps per sq. ft. is left as a dark, rough electrodeposit with no trace of brightness.
- the naphthol polyoxyalkylate and the polyethylenimine act synergistically to provide a bright, lustrous electrodeposit from about 12 amps per sq. ft. to well over 200 amps per sq. ft. In addition to being extremely bright, the deposit is quite ductile.
- the current densities below 12 amps per sq. ft. can be made bright by the addition of between 0.01 and 10 gms. per liter of a substance selected from the group consisting of anisaldehyde, piperonal, veratraldehyde, benzaldehyde, vanillan, benzylidene acetone, and cinnamic aldehyde.
- An aqueous, acid electroplating bath for producing a bright, lustrous electrodeposit of zinc containing zinc ions, and chloride ions and dissolved therein naphthol polyoxyalkylate having the formula:
- R is hydrogen or methyl
- x is about 8 to 20 and polyethylenimine having the formula:
- R is hydrogen, methyl, ethyl, propyl, hydroxyethyl, 2 hydroxy propyl, 3-hydroxy propyl, 2- aminoethyl, 2-aminopropyl, or 3-aminopropyl, and y is about 10 to about 20.
