Non-ferrous metal, this product be widely used in refrigeration, lamp decoration, hardware appliance, instrument and meter, chemical industry,
The industry manufacture field such as Aero-Space.
The characteristic of silver solder makes people select it within the quite a long time, but due to silver content
Height, the market demand is big, therefore the silver expended is quite a lot of；In metal, the price of silver is higher, therefore silver solder
Price much higher relative to other phosphor-copper welding rods；A lot of silver solders add cadmium element, uses process
In environment caused certain pollution.
Summary of the invention
It is an object of the invention to provide a kind of phosphor-copper welding rod, to substitute existing silver solder, solve existing
Silver solder cost of material is high, production process pollutes the problem of environment, has that fusing point is low, welding quality simultaneously
Advantages of higher.
Further object is that the preparation method that a kind of phosphor-copper welding rod is provided, solve existing silver soldering
Bar preparation process pollutes environment, relatively costly problem.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A kind of phosphor-copper welding rod, is prepared from cathode copper, phosphorus block and cloud tin for primary raw material, described phosphor-copper
In welding rod, the percentage by weight of each element is:
Copper 46.22%；Phosphorus 50.53%；Tin 2.73%；Other metals 0.52%.
Preparation process comprises the steps:
1), dispensing: weigh in proportion and join cathode copper, phosphorus block and cloud block tin；
2), melting: cathode copper, phosphorus block, three kinds of raw materials of cloud block tin are added simultaneously to intermediate frequency furnace, are heated to
Other solid metallics are added during liquid；
3), die reshaping: the compound in smelting furnace is poured in mould, until its cool down after the most plastic；
4), heat and machining: the semi-finished product of shaping are placed in electrothermal furnace and are heated to 530 degrees Celsius,
Then it is placed in hydraulic press, is squeezed into the welding rod of different size according to mould size；
5), cutting: the welding rod squeezed out is cut into 50cm length；
6), finished product it is packaged as through after the assay was approved.
Compared with prior art, the invention have the benefit that
The phosphor-copper welding rod of the present invention is to be prepared from for primary raw material, not only with cathode copper, phosphorus block and cloud tin
Solve a large amount of silver-colored, the problem that cost is high of existing silver solder series, and have fusing point relatively low,
The advantage that ratio of brazing area is high and welding precision is high, can be widely applied to refrigeration, lamp decoration, hardware appliance, instrument
The industry manufacture field such as instruments and meters, chemical industry, Aero-Space.Phosphor-copper welding rod preparation process of the present invention is to environment
Polluting little, preparation cost is low, and technological requirement is low, and whole preparation process is without special installation.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further expanded description, it is to be noted that this
Zinc-aluminium rareearth alloy coated steel strand wires of invention and preparation method thereof is not limited to described concrete preparation work
Skill.Those of ordinary skill in the art are understood, even if the following description content does not makes any adjustments or repaiies
Just, it is also possible to be directly applied at this in other similar components unspecified and preparation technology.
Embodiment 1
9208 phosphor-copper welding rods (black), specification is vertical bar 500mm,With cathode copper,
Phosphorus block and cloud tin are that primary raw material is prepared from, and technological process is as follows:
Dispensing-melting-die reshaping-heating, machining-cutting-check-pack-dispatch from the factory
Preparation process is specific as follows:
1), dispensing: weigh in proportion and join cathode copper, phosphorus block and cloud block tin；
2), melting: cathode copper, phosphorus block, three kinds of raw materials of cloud block tin are added simultaneously to intermediate frequency furnace, are heated to
Other solid metallics are added during liquid；
3), die reshaping: the compound in smelting furnace is poured in mould, until its cool down after the most plastic；
4), heat and machining: the semi-finished product of shaping are placed in electrothermal furnace and are heated to 530 degrees Celsius,
Then it is placed in hydraulic press, according to mould size, is squeezed into the welding rod of different size；
5), cutting: the welding rod squeezed out is cut into 50cm length；
6) finished product it is packaged as through after the assay was approved.
Take 9208 phosphor-copper welding rods (black) prepared by the present embodiment and carry out following performance test:
1, fusing point
Being measured by this area conventional method, fusing point is 580 °, and silver content difference pressed by silver solder, molten
Point range is between 620～800 °, and therefore, the molten point of the present embodiment 9208 phosphor-copper welding rod (black) is less than
Silver solder.
2, ratio of brazing area test
In production process, main ratio of brazing area passes judgment on welding quality at present, and solder, with when weldment contacts, melts
Change solder to treating that weldment diffusion inside is permeated, produced specific alloy layer, this generation alloy-layer
Proportionate relationship is called ratio of brazing area.
In test experience, with the KT10100A contact of cam controller as research object, with different
Solder, as variable, uses the mode of soldering to weld AgCdO contact and brass copper piece, by surveying
Examination ratio of brazing area judges the quality of solder contacts.
Contact material used by this experiment is patina cadmium sheet material, and solder used is prepared by the present embodiment respectively
9208 phosphor-copper welding rods and 50% containing silver solder.The JTUIS-IV using Xi'an Communications University to develop surpasses
Acoustic imaging Non-Destructive Testing carries out welding ratio of brazing area test.
Test report shows: the contact of the present embodiment 9208 phosphor-copper welding rod welding, ratio of brazing area reaches 99%；
And the ratio of brazing area that test as a comparison 50% containing silver solder is 83%, therefore the present embodiment 9208 phosphor-copper weldering
High containing silver solder than 50% of the ratio of brazing area of bar, welding quality aspect is better than silver solder.
3, environmental protection tests
Detection method: International Electrotechnical Commission IEC62321:2008
Testing result is as follows:
| Unit | Result | Limit value | Conclusion | Detecting instrument | |
| Pb | mg/kg | 13 | 40000 | Qualified | ICP-OES |
| Cd | mg/kg | Do not detect | 100 | Qualified | ICP-OES |
| Hg | mg/kg | Do not detect | 1000 | Qualified | ICP-OES |
| Cr | mg/kg | Do not detect | 1000 | Qualified | UV |
It will be apparent from the above that, compared with silver solder, the present embodiment 9208 phosphor-copper welding rod have fusing point relatively low,
Ratio of brazing area height and the advantage of environmental protection, as the substitute products of silver solder, can preferably meet corresponding industry system
Make the use requirement in field.
