Based on the chemical property of chemical reagent, the invention reduces the cost and increases the efficiency, the resistance of the obtained chemical conversion coating is below 1Omega, and the solution formulation is suitable for the conductivity treatment of almost all chemical conversion coatings of Mg alloy.
Description
Technical field
The invention belongs to technical field of surface, what relate to is a kind of tartrate magnesium alloy surface chemical conversion film conductive treatment solution, particularly a kind of environment-friendly type tartrate magnesium alloy surface chemical conversion film conductive treatment solution.
Background technology
Magnesium alloy is easy to corrosion in various corrosive mediums.Usually handle with chemical conversion film and improve its solidity to corrosion.In order to guarantee the performance of electronic product, to carry out conductive processing to chemical conversion film usually.It is in order to ensure that it has certain electroconductibility under air dielectric, to guarantee that the static that produces in the electronic product operational process in time discharges that magnesium alloy surface chemical conversion film is carried out conductive processing.Patent 02132772.6 and 200510035316.5 has been narrated a kind of prescription of Mg alloy surface treatment soln respectively, and all more than 100 Ω, it handles the performance that can influence electronic product to the chemical conversion membrane resistance of formation at Mg alloy surface but both fill a prescription.
Summary of the invention
Purpose of the present invention is intended at above deficiency, and a kind of environment-friendly type tartrate magnesium alloy surface chemical conversion film conductive treatment solution is provided.The present invention utilizes the chemical property of chemical reagent, has reduced cost, has improved efficient, and the chemical conversion membrane resistance of formation is below 1 Ω, and this prescription is fit to nearly all magnesium alloy chemical conversion film conductive processing technology.
The objective of the invention is to be achieved through the following technical solutions:
The weight percent of tartrate magnesium alloy surface chemical conversion film conductive treatment solution component of the present invention and each component is: tartrate: 10-15%, salicylate 5-10%, organic alcohol: 1-5%, organic amine: 1-5%, water: 75-80%;
Described tartrate is a kind of in sodium tartrate, the tartrate.Described salicylate is a kind of in Whitfield's ointment, the sodium salicylate.Described organic alcohol is a kind of in trolamine, the glycerol.Described organic amine is a kind of in aniline, the O-Phenylene Diamine.Described water is distilled water, a kind of in the deionized water.
The principle of tartrate conductive processing is that the Mg alloy surface that forms chemical conversion film reacts in the solution of tartrate, forms one deck tartrate compound, attached to its surface, reaches the purpose that improves the chemical conversion membrane conductivity.
The present invention has substantive distinguishing features and marked improvement, the present invention adopts tartrate solution, thereby the conductive capability of solution and dispersive ability are better, it is by the prescription of development research, well utilize the chemical property of chemical reagent and reduced cost, improved efficient, the chemical conversion membrane resistance of formation is below 1 Ω.
