The electrolyte comprises 50-56g/L of stannous fluoboric acid, 110-120g/L of fluorboric acid, 3-5g/L of gelatin, 0.4-0.8g/L of 2-naphthol, 8-12mL/L of alcohol, 4-6mL/L of formaldehyde and 10-12g/L of a brightener. The electrolyte has the advantages of fast precipitation speed, wide current density range, and low electricity energy consumption, and a coating obtained after electroplating using the electrolyte has the advantages of fineness, pure white, luster, maintaining convenience and wide application range.
Description
Technical field
The present invention relates to a kind of electrolytic solution.
Background technology
In present daily production, life process, copper lines application is very extensive, in order to improve erosion resistance, electroconductibility, mostly carries out silver-plated, zinc-plated processing in copper line surface.
Carry out silver-plated processing, although silver layer has stronger corrosion resistance, long-term exposure is in air, silver-coated copper wire surface is easy to work with airborne sulfide, halogenide etc., causes surface variable color comprehensively, not only the broken outward appearance of having changed, make contact resistance increase, brazing property degenerates simultaneously.Find through experiment, the essence of silvered film variable color is surface ion, if coating purity is inadequate, contains the impurity such as micro-zinc, iron, copper, forms corrosion microbattery on surface, has accelerated silver-colored ionization process; If silvered film surface irregularity porous, more easily condenses moisture and causes silvered film variable color with entering corrosive medium.
In Chinese Patent Application No.: disclose a kind of tin-plating round copper wire in 201110202378.6.It comprises copper cash and be wrapped in the silvered film outside copper cash, and described copper cash and silvered film are provided with at least two-layer tin coating.Silver-colored long-term exposure in this technical scheme is in air, and silver-coated copper wire surface is easy to work with airborne sulfide, halogenide etc., causes surface variable color comprehensively, the not only broken outward appearance of having changed, make contact resistance increase, brazing property degenerates simultaneously, and this technical scheme haves much room for improvement.
For this reason, a lot of people carry out electroplating surfaces with tin processing to copper lines, gather acidity or alkaline tin plating.But acid zinc-plated sedimentation speed is slow, and current consumption is large, the pre-treatment before electroplating is had relatively high expectations.Alkaline tin plating is because electric discharge is the stannate radicle of+4 valencys, and electrochemical equivalent is low, therefore obtains tin coating speed slower; Meanwhile, current density can not improve, and affects efficiency.
Summary of the invention
For the problems referred to above, the invention provides a kind of electrolytic solution, there is sedimentation speed fast, the advantage such as current density range is wide, and power consumption is low.
In order to address the above problem, technical scheme provided by the invention is:
A kind of electrolytic solution, is made up of following component and mass ratio: stannous fluoboric acid: 50-56g/L, fluoroboric acid: 110-120g/L, gelatin: 3-5g/L, beta naphthal: 0.4-0.8g/L, alcohol: 8-12mL/L, formaldehyde: 4-6mL/L, brightening agent: 10-12g/L.
