Abstract

The present application discloses an electroless nickel plating solution for a steel strip and a nickel plating method thereof, including a solution A and a solution B, and the ratio of the solution A to the solution B is 1:2.5; wherein the solution A includes by weight: nickel sulfate 30 -85 parts, 20-75 parts of sodium hypophosphite, 15-45 parts of citric acid, 10-25 parts of sodium lauryl sulfate, 10-30 parts of sodium borohydride, 5-20 parts of sodium phenyl disulfonate, 10-40 parts of potassium benzoate and 200-500 parts of deionized water, the pH value is adjusted to 8.5-9.5; the solution B includes by weight: 60-110 parts of nickel nitrate, 30-90 parts of potassium sulfate, triethanolamine 20-70 parts, 5-25 parts of water-soluble gluconate, 20-60 parts of amino carboxylic acid, 10-55 parts of sulfurized fatty acid ester, 20-50 parts and 300-700 parts of sodium dodecylbenzenesulfonate Ionized water, pH adjusted to 3‑4. Therefore, the steel strip is subjected to electroless nickel plating twice, the first time a transition layer is formed on the surface of the steel strip, and then the second electroless nickel plating is performed, which can ensure that the surface of the steel strip has a good bonding force of electroless nickel plating and a service life. Long, the process time is short.

Description

technical field [0001] The invention relates to electroless nickel plating, in particular to a steel strip electroless nickel plating solution and a nickel plating method thereof. Background technique [0002] The steel strip has active chemical properties and poor corrosion resistance, so it needs anti-corrosion treatment on its surface. However, the traditional nickel-plating process for steel strip has short service life, poor anti-corrosion effect and long process time. Contents of the invention [0003] The object of the present invention is to provide a steel strip electroless nickel plating solution and a nickel plating method thereof, which can solve one or more of the above-mentioned problems in the prior art. [0004] Steel strip electroless nickel plating solution of the present invention, composition is as follows: [0005] Including solution A and solution B, the ratio of solution A to solution B is 1:2.5; wherein said solution A includes by weight: 30-85 par...
