Abstract
The invention discloses a chemical treatment liquid used for nickel plating of a copper wire. The chemical treatment liquid is characterized in that the chemical treatment liquid comprises 40-60g/l of anhydrous sodium carbonate, 50-70g/l of sodium citrate and 4-6g/l of an advanced washing liquid, the temperature is 50-70DEG C, and the treatment time is 4-8s. The above formula is simple and practical, the use of sodium citrate to substitute traditional trisodium phosphate realizes environmental protection, and sodium citrate has the characteristics of good water solubility, excellent chelating effect on Ca<2+>, Mg<2+> and other metal ions in water, biodegradation, strong disperse capability and redeposition resistance, and the like, and obviously increases the decontamination capability of the washing liquid.
Description
Technical field
The present invention relates to copper line surface process field, be specifically related to a kind of chemical pretreatment solution for copper cash nickel plating.
Background technology
Nickel has good corrosion resistance, easily passivation in air, and ability highly basic, also slower with hydrochloric acid and effect of sulfuric acid.The current potential of nickel is than copper for negative, and the nickel dam on nickel plated copper wire can play anodic coating effect to copper, therefore more corrosion-resistant than silver-coated copper wire.The temperature resistant grade of nickel plated copper wire is higher than silver-coated copper wire, can reach 260 ℃.In view of the foregoing, nickel plated copper wire is widely used as the conductor wire core of resistant to elevated temperatures aircraft wire and other extraordinary hookup wire.As requested, while manufacturing nickel plating annealed copper wire, must be to the pre-treatment of carrying out before copper cash nickel plating, the quality of the performance such as the sticking power of nickel dam and resistance to corrosion on nickel plated copper wire, the pretreatment quality with copper cash before nickel plating is relevant.Based on this, now study a kind of chemical pretreatment solution for copper cash nickel plating, efficiently solve this problem.
