Description
Technical field
This application involves a kind of coating weld-rings and preparation method thereof that coating adhesiveness is strong.
Background technique
Soldering refers to that solder and weldment lower than weldment fusing point while heated to after brazing filler metal melts temperature, utilize liquid solder
The welding method that the gap of filling solid workpieces connects metal.Leading intermediate temperature solder to be used on the market has copper-based pricker at present
Material, silver solder etc..Most of silver solder needs to cooperate scaling powder when in use, and scaling powder can play activation table in welding
Face avoids the effects of oxidation, using can obtain better welding effect.
Most of phosphorous copper base solder when in use, since P elements have self-fluxing effect, can be mismatched in welding
Brazing flux uses completion welding.But in the narrow weldering for have higher requirements to mobility and surface quality using phosphorous copper base solder
When seam, often because solder fluidity and wetability are insufficient, leads to problems such as to lack weldering, insufficient (incomplete) penetration, lead to product defect rate mistake
It is high.
The use of scaling powder at present mainly passes through is applied to welding position use by hand, and this results in welding sequences
Low, the extra brazing flux of utilization rate that is complicated, smearing brazing flux will cause pollution, impact to environment.In addition to these problems, apply
The uncertainty for smearing brazing flux personnel operation also results in Welding Problems.
In order to improve welding efficiency and stability, mitigate environmental pressure caused by welding, medicine core, coating etc. are compound at present
Solder receives extensive pay attention to and exploitation.But the flux coated brazingrod produced on the market at present, the adhesive ability of surface coating is poor,
During transportation, surface coating can lead to client in use, weld-ring surface pricker underdosage, out because collision be lost
Now a large amount of defective products.
Summary of the invention
The technical issues of the application solves is to overcome the above deficiencies in the existing technologies, and provide a kind of coating attachment
The strong coating weld-ring and preparation method thereof of power.The weld-ring coating adhesive force is strong, and coating loss is small during transportation, and welding is stablized
Property it is good, have good mobility, can be improved bead weld soldering qualification rate and welding efficiency.Especially suitable for high-frequency induction
Soldering.
The present invention solves technical solution used by above-mentioned technical problem
A kind of coating weld-ring, including solder and brazing flux, it is characterized in that the coating weld-ring is only bonded by solder and brazing flux.
Herein described solder is annular in shape and is located at internal layer, and the surface of solder is formed uniformly (dipping, coating or other sides
Formula) binder, brazing flux be covered on binder formed coating weld-ring outer layer (coating).
The present invention solves technical solution used by above-mentioned technical problem further include:
A kind of preparation method of coating weld-ring, it is characterized in that the following steps are included:
Solder ring surface forms uniform adhesive layer；
Brazing flux is attached to formation coating weld-ring semi-finished product on the solder ring for speckle with binder；
Coating weld-ring semi-finished product (the solder ring for speckling with brazing flux and binder) are fixed-type by heating polishing.
Since binder is evenly distributed in solder ring surface, the brazing flux and direct warp that are bonded in by binder on solder ring
It crosses surface to compare coated in the brazing flux on solder ring, there is better Adhesion property, can be reduced brazing flux during Product transport
It falls off, guarantees that weld-ring surface still has one layer of uniform brazing flux in welding, guarantee the stability of welding.
By to bonding brazing flux solder ring carry out heating polishing it is fixed-type, can guarantee that binder is completely dried, and
The stability of coating weld-ring size is further increased, and weld-ring size influences weld-ring assemble welding, dimensionally stable can reduce card
Ring, and fit-up gap is reduced, welding effect is improved, failure welding rate is reduced.
Solder ring surface forms uniform adhesive layer step: the binder prepared being covered on solder ring, in pricker
Expect that ring surface forms one layer of uniform adhesive layer.
The binder is the mixture of polyurethane and diluent, and diluent is butyl acetate, in acetone, dimethyl carbonate
It is one or more, wherein polyurethane accounts for the 80-90% of mixture gross mass, and diluent accounts for the 10-20% of mixture gross mass.
After binder prepares, it could be used by stirring evenly.In order to make binder more evenly, binder can be heated to
80 degrees Celsius are uniformly mixed.
Solder ring can be used spraying or dipping (dipping) mode and be formed uniformly adhesive layer in solder ring surface.The side of spraying
Formula can be with are as follows: and the solder ring of clean surface is laid on plate, binder is sprayed on solder ring using atomizing lance, or
Solder ring is placed in bobbing machine by person, the spraying adhesive on vibration solder ring.
The concrete mode of dipping are as follows: the solder ring of clean surface is completely immersed in and is prepared in binder, then from binder
It takes out, until there is no until binder drippage, it is viscous that solder ring soaking time should be such that the solder ring surface taken out is evenly distributed with
Agent is tied, generally 1-10 minutes, this both of which can guarantee that solder ring surface uniformly adheres to binder, carry out for brazing flux attachment
Prepare.
Brazing flux is attached on the solder ring for speckling with binder: there is the solder ring of binder to turn in brazing flux powder surface
Rolling contact, brazing flux are attached on solder ring, obtain the semi-finished product for being attached with brazing flux.
The brazing flux is the corresponding FB105 brazing flux of silver-base solder.Preferred brazing flux is needed by micronization processes, and refinement can adopt
With planetary ball mill ball milling 24 hours, crosses 200 mesh screens and obtain.
The solder ring is contacted with the rolling of brazing flux can put into a centrifuge rotation by mixing solder ring and brazing flux
It realizes.Preferably for usable low speed centrifuge to rotating after solder ring and brazing flux mixing, revolving speed is not higher than 500 turns/min.
It can make each solder ring surface sufficiently using rolling contact and brazing flux contact, keep surface attachment brazing flux uniform, utilize solder
The rolling of ring, which is beaten, makes surface brazing flux layer more consolidation, further improves the adhesiveness of brazing flux.
Coating weld-ring is fixed-type: in order to guarantee the adhesion property of coating weld-ring coating, and producing the medicine of dimensionally stable
The assembly of skin weld-ring adaptation client.It needs to polish coating weld-ring surface of semi-finished.It is preferably viscous in order to have brazing flux
Attached performance can heat coating weld-ring semi-finished product, 40-100 DEG C of heating temperature.
Polishing can be by being put into the shake of three-D lapping machine by coating weld-ring semi-finished product and with ball milling pearl (polishing pearl)
Dynamic grinding realizes that the mass ratio of ball milling pearl and coating weld-ring semi-finished product is 1:2 to 1:1.To keep coating weld-ring surface coating uniform
Hot wind can ground while be blown into densification, and hot blast temperature control is 40-100 DEG C.
Preferably, the ball milling pearl is the half that zirconium oxide ball milling pearl diameter is coating weld-ring internal diameter, and ball milling pearl can
To pass through coating weld-ring inner ring, polishing effect can be realized to coating weld-ring Internal and external cycle surface synchronization.Ball milling pearl and coating weld-ring
During vibration, the coating layer on ball milling pearl and coating weld-ring surface is collided, so that brazing flux is further compacted, improves the adherency of brazing flux
Property, reduce loss late.
Coating weld-ring provided by the invention and preparation method thereof, simple for structure, coating cohesive force is strong, shakes by three-D
Appearance uniform is fine and close after grinder processing, and adhesiveness and thickness stability are good, and coating weld-ring is easily assembled and uses.
