Abstract
A manufacturing process of plating copper by using aluminum-magnesium copper-plating wire comprises the following steps: arranging wire, cleaning by alkali, cleaning by water, cleaning by sulfuric acid, cleaning by water, cleaning by alkali, cleaning by water, a first time soaking zinc, cleaning by water, removing the zinc by nitric acid, cleaning by water, a second time soaking zinc, cleaning by water, cleaning by hot water, pre-plating nickel, cleaning by water, activating, acidicly plating copper, cleaning by water, carrying out the anti-oxidation treatment, cleaning by hot water, drying and taking out the wire. The manufacturing process is characterized in that the process of the first time zinc soaking is that completing the first time zinc soaking in solution with temperature of 12-27DEG C for 30-60 sec after mixing with 60 parts water, 7 parts zinc oxide, 31 parts superalkali, 2 parts potassium sodium tartrate and 0.06 parts iron trichloride. By adopting the manufacturing process of the invention, the aluminum-magnesium copper-plating wire has the double advantages that aluminium conductor has light weight and low cost, copper conductor has high conductivity and good chemical stability, wherein the specific weight of copper is about 18-19%, mean density is 2.8g/cm3, the length of aluminum-magnesium copper plating wire whose size and weight are the same with that of pure copper wire is 3.1 times than that of the pure copper wire, tensile strength is more than or equal to 210, which enables the aluminum-magnesium copper plating wire uneasily to break and improves the quality of the products.
Description
Technical field
The present invention relates to the production method of electric wire and cable conductor line in inner conductor, audio frequency and video line conductor, data class cable telephony line, grid line and the electrical equipment, especially about a kind of technique for producing aluminum magnesium plating copper wire copper-coating.
Background technology
Along with the technical progress of the in short supply and material industry of world's copper resource, the whole world increases and the minimizing day by day of earth resources day by day to the copper resource requirement, and from the angle of resource, it is the inexorable trend in the global range from now on that metal prices such as copper go up.The appearance of double metallic composite material should be accumulate and be given birth to, and the electroconductibility of fine aluminium is fine, is only second to silver, copper, and it can make lead and cable by instead of part copper in power industry.The matrix material of copper and aluminium in last century the seventies come across the U.S., and be applied to communication cable and since the advantage of the light weight of this material and good electrical conductivity gradually cotton covered wire, automobile cable, insulated wire and in apply in the line ball cable.Be to produce with covered at that time, the proportion of used copper is general more more than 32%, though be to save than having had on production cost with the fine copper product significantly, still cost is higher, so the magnalium coppered wire is shown one's talent.With aluminium is main raw material(s), is aided with the composition (can increase the tensile strength of product) of magnesium, makes the magnalium bar, and then makes the magnalium coppered wire through the method for chemical plating.The proportion of magnalium coppered wire copper layer only accounts for about 18-19% mean density 2.8g/cm
3, the length of the magnalium coppered wire of same size, weight is 3.1 times of pure copper wire, produces 1 ton of magnalium coppered wire and can save 2.9 tons of fine copper.Owing to wherein added specific other rare compositions based on magnesium, make magnalium coppered wire tensile strength exceed 10-20% than the copper-clad aluminum conductor of the first-generation, the magnalium coppered wire of making so just can be the same with the product of fine copper, and not easily broken, production capacity further promotes.The high frequency conductivity of magnalium copper plated material is splendid, and power frequency is during greater than 5MHz, because skin effect, electric conductivity is identical with copper.
But problem be common aluminium in copper magnesium in the process that the instead of pure copper cash is being produced, broken end, peeling, dew aluminium phenomenon appear easily, be not only the close product of electroconductibility and a lot of client needs, and will be easy to produce, enhance productivity.Adherence, the homogeneity of the copper layer that manufacturing magnalium copper facing silk should be noted that.If adherence, homogeneity are bad, peeling will appear in the magnalium copper facing bar of being produced in the process of carefully stretching, reveal phenomenon such as aluminium.
Summary of the invention
At above deficiency, the object of the present invention is to provide a kind of technique for producing aluminum magnesium plating copper wire copper-coating, be that the magnalium line is through cleaning (alkali cleaning, pickling) repeatedly, after soaking zinc, moving back zinc technology, carry out preplating copper then, and a kind of magnalium coppered wire that obtains after activated, product can prolong for 1/5 time than general wire rod aspect anti-oxidant, the solid colour of the aluminium in copper magnesium line of feasible magnalium coppered wire of electroplating out and covered.
Technical scheme of the present invention realizes in the following manner: a kind of technique for producing aluminum magnesium plating copper wire copper-coating, may further comprise the steps: put silk-alkali cleaning-washing-sulfuric acid to wash-wash-soak zinc-washing-nitric acid alkali cleaning-washing-first time to move back and soak zinc-washing-hot water wash-nickel preplating-washing-activation-acid copper-plating-washing-anti-oxidation processing-hot water wash-oven dry-receipts silk zinc-washing-second time, it is characterized in that:
1), described first time, dip galvanizing technique was: will be that 30-60 second, temperature are to finish in 12-27 ℃ the solution to soak zinc for the first time in the time after 62 parts in water, 7 parts in zinc oxide, 31 parts in sodium hydroxide, 2 parts of Seignette salts, 0.06 part of mixing of iron trichloride;
2), described second time, dip galvanizing technique was: will be that 20-40 second, temperature are finished in 20-40 ℃ solution and soaked zinc for the second time in the time after 72 parts in water, 15 parts in zinc oxide, 9 parts in sodium hydroxide, 4 parts of Seignette salts, 0.01 part of iron trichloride, 0.002 part of mixing of SODIUMNITRATE;
3), described nickel preplating technology is: will transfer to pH value 5-5.5 after 80 parts in water, 16 parts of single nickel salts, 1 part in sodium-chlor, 3 parts of boric acid, 0.0008 part of mixing of sodium lauryl sulphate, temperature is finished nickel preplating in 18-35 ℃ solution;
4), described acid copper-plating technology is: will finish acid copper-plating in temperature in 20-25 ℃ solution after 78 parts in water, 16 parts in copper sulfate, 6 parts of mixing of sulfuric acid.
Adopt production technique of the present invention, the magnalium coppered wire has possessed simultaneously that aluminium conductor is in light weight, price is low and copper conductor electric conductivity height, two-fold advantage that chemical stability is good.This product surface is a copper, and the center is an aluminium, and the proportion of copper accounts for about 18-19%, mean density 2.8g/cm
3, the length of the magnalium coppered wire of same size, weight is 3.1 times of pure copper wire, and the high frequency conductivity of magnalium copper plated material is splendid, and power frequency is during greater than 5MHz, and because skin effect, electric conductivity is identical with copper.Owing in the production of aluminium bar, added the composition of magnesium, make the wire rod of producing like this, tensile strength 〉=210 are entirely identical to pure copper wire, and are not easily broken during production, improved quality product.
