Description
Technical Field
The invention relates to the field of aluminum alloy wire surface treatment, in particular to aluminum alloy wire surface reaction film treatment liquid and a treatment process thereof.
Background
The aluminum alloy wire core conductor is an essential material of a cable and a control cable, and the existing aluminum alloy wire electroplated copper product often has the following defects: the price and weight of copper are higher than those of aluminum materials, the cost is higher, and the surface of the copper layer is easy to oxidize to form an insulating film; the copper plating product has very easy corrosion and even decay when the copper plating surface is damaged due to the great difference of the electrode potentials of the metal contact interface, thereby greatly influencing the use effect of the product.
At present, aluminum materials are gradually used for replacing copper materials, but the biggest disadvantage of the aluminum materials is that the surface is easy to oxidize to form film resistance, so that the surface of the aluminum alloy material in the cable structure is particularly important to be subjected to corrosion prevention at present.
Disclosure of Invention
Based on the above, the invention aims to provide a treatment solution and a treatment process for a surface reaction film of an aluminum alloy wire, which can effectively seal micropores on the surface of a plating layer and the surface of a metal post-treatment surface of the aluminum alloy wire, prevent invasion of harmful gas and corrosive medium, and reduce the phenomena of induced points on the surface of the plating layer and yellowing of the plating layer due to corrosion.
The invention realizes the technical purposes through the following technical proposal:
the invention provides an aluminum alloy wire surface reaction film treatment solution which is mainly prepared from the following raw materials in parts by weight:
the dielectric agent is one or more selected from polyacetylene, polypyrrole, polyaniline and polyphenylacetylene;
the lubricant is one or more selected from base oils and animal fats. The main function of the dielectric agent is that the finished aluminum wire is not affected by the film layer, and external current is induced to the surface of the aluminum alloy wire base layer. The lubricant has the main effects of protecting the smoothness and the electrical stability of the surface of the aluminum wire blank, greatly reducing the extra electrostatic reaction on the surface of the aluminum wire blank during production, reducing the friction resistance of the surface of the film layer of the finished aluminum wire, and avoiding the damage of the film layer caused by external friction when the finished aluminum material is transported and used.
The aluminum alloy wire surface reaction film treatment liquid provided by the invention uses one or more of polyacetylene, polypyrrole, polyaniline and polyphenylacetylene as an inducer, uses base oil and animal grease as a lubricant, and is compounded with a corrosion inhibitor, a stabilizer, an anti-aging material and a solvent.
Preferably, the corrosion inhibitor is selected from one or more of animal fat, octadecyl trimethyl bromide and higher alkylamine derivatives. The corrosion inhibitor has the main functions of slightly eroding the surface of the aluminum wire blank and activating the chemical reaction performance of the surface of the aluminum wire blank.
Preferably, the stabilizer is selected from one or more of bis (4-hydroxyphenyl) sulfone, 2-6-di-tert-butylphenol and resorcinol. The stabilizer has the main effects of enhancing chemical stability when the medicament is prepared and used, and improving heat resistance of the film in the finished film.
Preferably, the anti-aging material is selected from one or more of 4-hydroxydodecanoyl anilide and 4-hydroxyoctadecanoyl anilide. The anti-aging material has the main effects of enhancing the aging resistance of the finished film, prolonging the service life of the film, having microscopic heat conduction performance and improving the heat dissipation performance of the film.
Preferably, the solvent is selected from one or more of trichloroethane, trichloroethylene, tetrachloroethylene, toluene, xylene, and trichloromethane. The solvent can strengthen the chemical stability of the finished film and prolong the service life of the film.
Preferably, the solvent also comprises 3-8% of absolute ethyl alcohol by volume percent. The addition of a certain amount of absolute ethyl alcohol to the solvent can eliminate the influence of harmful medium phosgene.
As a preferred embodiment of the present invention, the treatment solution is mainly prepared from the following raw materials in parts by weight:
the dielectric agent is polyacetylene, and the lubricant is poly alpha olefin.
The dielectric agent is polyacetylene, the lubricant is polyalphaolefin, and the treatment liquid within the preferable range is adopted for treatment, so that the mechanical property, the electrical conductivity and the corrosion resistance of the aluminum alloy wire are relatively better.
The invention also provides a treatment process of the aluminum alloy wire surface reaction film, which adopts the treatment liquid to treat the aluminum alloy surface.
Specifically, the method comprises the following steps: cleaning and coarsening the surface of the aluminum alloy wire blank, removing film stains with powdery surfaces, drying, soaking in the treatment liquid for 3-5 minutes, drying and packaging.
More specifically, the process comprises the steps of:
s1, degreasing an aluminum alloy wire blank by adopting a 5% weak alkaline degreasing agent, and cleaning, wherein the 5% weak alkaline degreasing agent comprises the following raw materials in percentage by mass: sodium bicarbonate 2%, sodium phosphate 2.5%, boric acid 0.5%, pure water 95%;
s2, carrying out microetching treatment on the aluminum alloy wire blank subjected to degreasing treatment by adopting a 5% weak alkaline microetching agent, and cleaning, wherein the 5% weak alkaline microetching agent comprises the following raw materials in percentage by mass: 3.5% of sodium hydroxide, 1.5% of sodium phosphate and 95% of pure water;
s3, neutralizing and cleaning the aluminum alloy wire blank subjected to microetching treatment by adopting an 8% acid neutralization stain remover, wherein the 8% acid neutralization stain remover comprises the following raw materials in percentage by mass: 25% of nitric acid and 75% of pure water;
s4, drying the aluminum alloy wire blank processed in the step S3, then placing the aluminum alloy wire blank into the processing liquid to be soaked for 3-5 minutes, drying and packaging.
The treatment solution and the surface reaction film treatment process can enable the surface of the aluminum alloy wire to react in situ to form an anti-corrosion conductive film layer with the thickness of nanometer level in a chemical bond mode, so that the surface contact resistance and the anti-corrosion grade of the metal wire can reach the test use standard; when the surface treatment is carried out, microscopic heat conduction materials such as an inducer, an anti-aging material and the like are added, so that the surface infrared radiation capacity and the heat conductivity coefficient of the nanoscale film are enhanced, the heat radiation performance of the cable wrapping structure is improved, the microstructure of the surface film has a crystal honeycomb hole-shaped structure, electromagnetic waves of the surface film are partially transmitted and partially diffusely reflected on an incident film layer, and the surface film has a certain wave absorbing function.
