Embodiment 1

[0046] Φ11 round copper rod formed by dipping and galvanizing figure 1 Composite conductor:

[0047] 1) Use a plate of Φ11 circular copper rod as the copper substrate 1, and manually polish the surface of the copper substrate 1;

[0048] 2) Roll the polished Φ11 round copper rod into a mosquito-repellent coil disc or an equal-diameter spring-type disc, and use a certain number of hanging rods to hang all of them firmly to ensure that they will not disperse when subjected to a certain impact force. Opening and deformation, when hanging, it is required that the copper rods of each circle do not overlap, and an appropriate interval is left between the copper rods of each circle. Clean the suspended workpiece with flowing water to remove the residue left during polishing;

[0049] 3) Carry out alkali washing and degreasing again, immerse the workpiece in the alkaline degreasing solution for degreasing, the temperature of the alkaline degreasing solution is 80° C., and the alkali...

Embodiment 2

[0064] Made of disc-shaped 4×25 flat copper strips such as figure 2 Composite conductor shown:

[0065] 1) Use about 50KG of 4×25 flat copper strip rolled into a spring-shaped disc as the copper substrate 1, and manually polish and polish the surface of the copper substrate 1;

[0066] 2) Hang the polished spring disc-shaped 4×25 flat copper substrate 1 on the hanger hanger, and hang all the copper strips firmly, and when subjected to a certain impact force, they will not scatter and deform. When hanging, it is required that the copper strips of each circle cannot overlap, and an appropriate distance should be left between each other. Clean the suspended workpiece with running water to remove the residue left during polishing;

[0067] 3) Carry out alkali washing and degreasing again, immerse the workpiece in an alkaline degreasing solution for degreasing, the temperature of the alkaline degreasing solution is 60°C, and the alkali washing and degreasing time is 20 minutes; ...

Embodiment 3

[0087] Composite conductor made of 4×40 straight flat copper bars:

[0088] 1) Mechanically grinding and polishing the surface of the conductor copper substrate 1 with 15 straight strips of 4×40 flat copper strips;

[0089] 2) Hang and firmly hang 15 straight 4×40 flat copper strips with a hanger, and clean them with running water after polishing to remove the residue left during polishing;

[0090] 3) Carry out alkali washing and degreasing again, immerse the workpiece in an alkaline degreasing solution for degreasing, the temperature of the alkaline degreasing solution is 70°C, and the alkali washing and degreasing time is 18 minutes; / l, Na 3 PO 4 22g / l, Na 2 CO 3 38g / l, water glass 4g / l, OP-10 emulsifier 2g / l;

[0091] 4) After degreasing, wash with hot water at 60°C for 1.5 minutes; then wash with deionized water at room temperature for 1.2 minutes;

[0092] 5) Pickling to remove the oxide skin, put the workpiece after thorough degreasing and cleaning into the mix...

Abstract

The invention discloses a compound copper conductor structure with decoration and antiseptic effect and manufacturing method thereof. The structure includes that: the surface of copper base material is covered with a zinc or zinc alloy surface layer with the thickness of 45-85 Mum, a diffusion layer is formed between the copper base material and the zinc or zinc alloy surface layer. The process method of the compound copper conductor includes alkali cleaning for degreasing, acid washing for de-scaling, twice cleaning, dipping plating asistant agent, drying work pieces to be preheated, dippingmolten zinc alloy liquid, protective gas wiping and cooling, heat preservation after cooling, hole sealing and the like. The compound copper conductor of the invention has the advantages that corrosion resistance of surface is improved, performances of conductivity, heat conduction, solderability and low contact resistance are ensured, and appearance is favourable and decoration compatibility is strong.

Description

technical field [0001] The invention relates to a structure of a composite copper conductor with decorative and anti-corrosion effects and a manufacturing method thereof, and belongs to the cross technical field of material surface science and physical chemistry. Background technique [0002] Copper and copper alloys are good conductor materials, which are widely used in daily necessities, household appliances, various machinery and electrical engineering fields due to their good electrical conductivity, thermal conductivity and weldability. However, bare copper and copper alloy conductor materials have poor chemical stability and strong self-oxidation in the air. If they encounter water, steam, sulfur dioxide, carbon dioxide, HCL and other gases, they will produce green spots or flakes of gray-green surface. It loses its true color and reduces its main performance. At this time, if it is used for surface installation, it will not only affect its decoration and coordination...
