Definitions

  • ABSTRACT A method for the electroplating of steel strip in a tin plating bath utilizing therein a brightening agent comg i; prising ethoxylated-naphthol sulfonic acid, wherein the ethylene oxide to naphthol ratio is 6 or 7:1.
  • the electrodeposition of tin can be effected in a variety of acid plating electrolytes.
  • all such plating processes in commercial use require at least three components: (1) an acid source, (2) a soluble tin salt and (3) one or more organic addition agents for the production of smooth, adherent and lustrous deposits of tin.
  • various polyalkylene oxides have been known to be effective. Examples of such brightening agents are shown in (1.8. Pat. No. 2,457,152.
  • the FIGURE is a graph illustrating the superior shelf life of the brightening agents of this invention.
  • the conductivity of the electrolyte is decreased by such excessive amounts of foam. Equally important, as the chain length is increased. the permissible plating range becomes narrower. That is,
  • FIGURE shows the amounts of tar-residue encountered in both phenosulfonic and sulfuric acid baths with ENSA-S and ENSA-6 brightening agents It may be seen that, in using the ENSA-S product, the amount of tar-residue encountered increases markedly after a storage period of about weeks, while no such increase is noted with the ENSA-6 product after a period of more than one year in duration.
  • a naphthol should generally be employed, since the B variety is known to be toxic.
  • the resulting adduct i.e. EN-6 or EN7
  • EN-6 or EN7 is then sulfonated at a temperature of 5090C, preferably about 8085C, with sulfuric acid having a concentration of at least about 90%, preferably 92-98%.
  • the temperature employed should be approximately inverse to the concentration of the H 50 That is, temperature should be maintained in the upper end of its range when acid concentration approaches about 90%. However, as the concentration of the acid employed increases. temperature should then be maintained at correspondingly lower temperatures, so that the temperature should be about 50C when an acid concentration of about oleum is employed.
  • the ENSA6 and ENSA-7 brightening agents of this preferably 3 to 5 g/l, of ENSA6 or ENSA7 prepared in the manner prescribed above and (3) about 6 to 30 g/l, of free acid (calculated as H 50
  • the acid may be added either as H or phenolsulfonic acid.
  • the temperature of the bath may vary from about 83 to 145F, preferably about to F.
  • An electrolyzing current of at least about 50 amps/ft. is passed to the substrate as cathode in sufficient stages to form an electroplated tin coating of desired thickness.
  • n 6 or 7
  • said agent having been prepared by the ethoxylation of a or ,8 naphthol with said n mols of ehtylene oxide and thereafter, at a temperature within the range 50C 90C, sulfonating the resultant product with sulfuric acid, the concentration of which is at least about 90 percent.
