Description

Manufacturing process of tinned copper strip
Technical Field
The invention belongs to the technical field of corrosion prevention of a water tank radiator core, and particularly relates to a preparation process of a tinned copper strip.
Background
In view of high-humidity high-salt fog environments such as offshore platforms, islands, seaside and belly lands, the water tank radiator core is corroded strongly, the durability of the water tank is greatly reduced, the replacement or maintenance cost is high, and the normal use of the generator set is seriously influenced. To current water tank, the anticorrosive general processing of core is at the anticorrosive heat conduction paint of top layer spraying, and because the adhesive force that the paint exists is general, its top layer thickness is thin hangs down easily, and it is thick easy to drop and the radiating effect is poor, therefore anticorrosive effect is general. The invention with publication number CN 107768474A discloses a manufacturing process of a tinned copper strip, which comprises the following steps: removing redundant copper powder on the outer surface of the copper wire; washing the outer surface of the copper wire after copper powder removal by using ethanol; infiltrating the copper wire washed by the ethanol through the soldering flux; calendering the copper wire infiltrated by the soldering flux, and calendering the cylindrical copper wire into a rectangular copper strip; annealing the copper strip; and coating tin on the annealed copper strip. The process can effectively reduce the copper powder on the surface of the copper wire and improve the finished product rate and the forming efficiency of the tinned copper strip, but the process of the tinned copper strip prepared by the process is complex, the equipment running cost is high, and the tinned copper strip with the thickness of 0.2-0.3cm is a target to be processed, so the requirement on the processing precision is relatively low.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a preparation process of a tinned copper strip, which is simple in process and low in cost, wherein the process is used for carrying out surface tinning on a copper strip with the thickness of only 0.035mm by a constant-temperature tin furnace, and then carrying out press forming by a special strip making machine and a strip making mould to obtain a finished product tinned copper strip.
The invention adopts the following technical scheme for solving the technical problems, and the preparation process of the tinned copper strip is characterized by comprising the following specific steps of: firstly, heating a tin furnace, melting 30Sn into liquid, and accurately controlling the temperature of the tin furnace to be constant 316 ℃ through a temperature sensor; carrying out surface treatment on the copper strip by using a cleaning solvent to ensure that the surface of the copper strip is clean and free of impurities, wherein the cleaning solvent consists of 3-6 parts by weight of hydrobromic acid, 2-8 parts by weight of hydrogen peroxide, 2-5 parts by weight of oleic acid diethanolamine, 4-9 parts by weight of penetrant ethylene glycol monobutyl ether and 30-50 parts by weight of deionized water; and then, carrying out surface layer tinning on the cleaned copper strip by a constant-temperature tin furnace, immediately cooling the copper strip in continuous clear water at the constant temperature of 65 ℃ after tinning to obtain a surface layer tinned copper strip, and then forming the surface layer tinned copper strip by a strip rolling machine to obtain a finished product tinned copper strip.
Preferably, the copper strip is a copper strip or a brass strip, and the thickness of the copper strip is 0.035 mm.
Compared with the prior art, the invention has the following beneficial effects: after the tinned copper strip is treated by a specific process, the surface layer of the tinned copper strip is uniformly covered with a layer of tin, and the tin is far more resistant to oxidation, acid and alkali corrosion than the common copper strip, has better heat conductivity, and has excellent effect on areas with higher salt spray concentration.

Detailed Description
The present invention is described in further detail below with reference to examples, but it should not be construed that the scope of the above subject matter of the present invention is limited to the following examples, and that all the technologies realized based on the above subject matter of the present invention belong to the scope of the present invention.
Firstly, heating a tin furnace, melting 30Sn into liquid, and accurately controlling the temperature of the tin furnace to be constant 316 ℃ through a temperature sensor; carrying out surface treatment on a red copper strip by using a cleaning solvent to ensure that the surface of the red copper strip is clean and free of impurities, wherein the cleaning solvent consists of 5 parts by weight of hydrobromic acid, 6 parts by weight of hydrogen peroxide, 4 parts by weight of oleic acid diethanolamine, 7 parts by weight of penetrant ethylene glycol butyl ether and 50 parts by weight of deionized water; and then, carrying out surface tinning on the copper strip by passing the cleaned copper strip through a constant-temperature tin furnace, immediately cooling the copper strip in continuous clear water at the constant temperature of 65 ℃ after tinning to prepare a surface tinned copper strip, and then forming the surface tinned copper strip by using a belt rolling machine to obtain a finished product tinned copper strip.
The thickness of the red copper belt is only 0.035mm, so that the flexibility and secondary processing type of the copper belt are easily damaged when the tin is plated on the high-temperature surface layer, the temperature is too high, and the red copper belt is deformed and cannot be processed again; the temperature is too low, the tin layer cannot be effectively and uniformly covered on the surface layer of the copper strip, and the anti-corrosion effect cannot be achieved; after the tin layer is formed, the copper strip cannot be effectively windowed and holed to form. The invention can effectively solve the process problems, can carry out secondary processing on the tinned copper strip under the condition of uniform tin layer of the copper strip, and meets the requirements of corrosion resistance and heat dissipation, and the preparation process of the tinned copper strip is initiated at home.
The common anticorrosive water tank is a first product in the whole radiator industry, at present, China strongly supports import and export trade, the demand of the outlet of a generator set is greatly increased in some islands, seasides and high-salt fog areas, particularly tourist cities or areas to be developed, but the common anticorrosive water tank is used in the areas with severe environment, the effect is extremely poor, the common anticorrosive water tank can be corroded in a short time, the power supply of the generator set is seriously influenced, and the influence on the product cognition of the export country in China is severe. The manufacturing process of the tinned copper strip can effectively solve the problems, so that the service life of the water tank can be prolonged by multiple times, and effective support is provided for the development of the project at home and abroad.
While there have been shown and described what are at present considered the fundamental principles of the invention, its essential features and advantages, the invention further resides in various changes and modifications which fall within the scope of the invention as claimed.
