Definitions

  • the present invention relates to aqueous, acidic solutions for the electrolytic deposition of tin and / or lead / tin alloys containing a mixture of tin and / or lead salts of an alkanesulfonic acid, free alkanesulfonic acid, the alkyl group of the alkanesulfonic acid consisting of 1 to 5 carbon atoms , non-ionic wetting agent and optionally aromatic and / or short-chain aldehydes and / or optionally aromatic ketones and / or optionally short-chain unsaturated carboxylic acids.
  • DE-PS 1 260 262 describes aldol condensation products which are added to aqueous baths for the electrodeposition of tin as brighteners.
  • US Pat. No. 2,525,942 relates to the use of alkanesulfonic acid derivatives in solution for metal deposition.
  • US Pat. No. 4,582,576 describes a method which deposits shiny tin-tin / lead layers from baths containing alkanesulfonic acid.
  • aqueous, acidic solutions described therein contain metal salts, free alkane or alkanol sulfonic acid, wetting agents, a short-chain aliphatic aldehyde, an aromatic aldehyde, optionally an aromatic ketone and an unsaturated, short-chain carboxylic acid.
  • the compositions described there have the disadvantage that they have only a poor load capacity in the high current density range.
  • the object on which the invention is based is to provide aqueous, acidic solutions which have a better load-bearing capacity in the high current density range and enable uniform gloss scattering over the entire current density range.
  • an aqueous, acidic solution for the electrolytic deposition of tin and / or lead / tin alloys containing a mixture of tin and / or lead salts of an alkanesulfonic acid, free alkanesulfonic acid, the alkyl group of the alkanesulfonic acid consists of 1 to 5 carbon atoms, non-ionic wetting agent and optionally aromatic and / or short-chain aldehydes and / or optionally aromatic ketones and / or optionally short-chain unsaturated carboxylic acids, characterized in that one or more reaction product (s) from acetaldehyde as a further brightener and / or an aldol condensation product of acetaldehyde with ammonia and / or acyclic ketones and / or aliphatic amines, amides, amino acids and / or hydrazine compounds, the concentration of the further brightener being 0.1
  • a non-ionic wetting agent of the alkylaryl polyglycol ether type is preferably selected as the wetting agent. If a mixture of a reaction product of acetaldehyde and / or its aldol condensation products with acyclic ketones is chosen as the brightener, the aliphatic ketone preferably contains 10 carbon atoms in the molecule. Naphthaldehyde, chloroacetophenone or benzalacetone, formaldehyde or acetaldehyde and, as unsaturated carboxylic acid, methacrylic acid or methyl methacrylic acid are preferably added to the aqueous, acidic solutions.
  • the aqueous, acidic solutions according to the invention preferably contain 5 to 25% by weight of the corresponding metal salt or salts, 6 to 20% by weight of the alkanesulfonic acid, 0.1 to 5% by weight of non-ionic wetting agent, 0.1 to 5 %
  • the aldol condensation product if appropriate 0.1 to 3% of the aromatic aldehyde, optionally 0.01 to 1.0% by weight of the aromatic ketone, optionally 0.01 to 1.0% by weight of the short-chain aliphatic aldehyde, and optionally 0.01 to 1 % of unsaturated carboxylic acid.
  • the information relates to mixtures that are adjusted to 1 liter of finished solution.
  • aldol condensation products according to DE-PS 1 260 262 in a process for the electrolytic deposition of tin and / or lead / tin alloys surprisingly leads to improved galvanic deposition in the high current density range, and at the same time uniform gloss scattering is achieved in the low current density range.
  • Process parameters The usability of the electrolyte was tested for tin and / or lead / tin deposition in a Hull cell according to DIN 50 957. Temperature: 20 - 25 ° C, exposure time: 5 minutes with mechanical stirring, anode tin or lead-tin analogous to the composition of the precipitation. Sheet steel cathode material, cell current 2, 3 or 4 amps per cell.
  • the sheet After adding 10 ml / l of the additive according to the invention, the sheet was uniformly glossy from 0.2 to 10 A / dm 2.
