Description
Technical field
The present invention relates to flux for solder technical field, in particular to a kind of more metal material solder scolding tin core solder flux
And preparation method thereof.
Background technique
The metal materials such as stainless steel, aluminium and aluminium alloy, magnesium and magnesium alloy, nickel and nickel alloy have corrosion-resistant, anti-oxidant, strong
High excellent characteristic is spent, but especially its corrosion-resistant, oxidation resistant good characteristic is to auto industry, space flight and aviation, electronics
It is a challenge for the welding technique in the fields such as instruments and meters and high-end equipment manufacturing industry.The principle that solder connects is added using scaling powder
The oxide removal of metallic substrate surface, the tin alloy of melting and the metal of the oxide eliminated are formed into metal alloy when hot
Compound welds together tin alloy solder with soldered metal.Stainless steel, aluminium and aluminium alloy, magnesium and magnesium alloy, nickel and nickel
The molecular structure stabilized of the metal and alloy materials such as alloy has inoxidizability and corrosion resistance, and traditional welding is when heated
Be difficult to remove its oxide on surface protective film, tin alloy can not formed alloy-layer, so as to cause that can not weld.How very well
Ground removes oxide film dissolving, improves welding efficiency, reduces residue and guarantee higher weld strength, is to stainless steel, aluminium and aluminium
The solution that alloy, magnesium and magnesium alloy, nickel and nickel alloy etc. are difficult to solder to metal material solder problem is crucial.
Currently, be essentially all with solder flux for the solder scolding tin core of welding metal material it is single, these solder flux are big
It is chiefly used in the welding of single metal material, versatility is poor；Meanwhile film of flux residue is more around solder joint after welding, it is difficult to clear
Wash clean, corrosivity are big；Additionally, there are easy formation dry joint, weld strength is low, pollutes the problems such as environment.Number of patent application is
A kind of nickel-plate alloy solder soldering tin core of CN201210250851.2 is described in scaling powder and preparation method thereof patent
Solder flux main component are as follows: resin 60~90%, organic acid 0.1~20%, organic amine 0.1~10%, metal salt 0.1~
20%, active reinforcing agent 0.1~2.0%, surfactant 0.1~2.0%, corrosion inhibiter 0.1~1.0% and antioxidant 0.1~
1.0%, the characteristics of this scaling powder is then to add the conducts such as metal salt and organic amine using rosin resin and organic acid as stripper
Activating agent, although this kind of scaling powder activity it is stronger, there are solder joint residual it is still more, not easy cleaning the problems such as, as the time increases
Long, residue butt welding spot corrosion is very serious.Number of patent application is that a kind of aluminium of CN88100868.0 and aluminum alloy soft soldering help
Solder flux patent describes flux constituent and weight ratio are as follows: contains the organic borofluoride 1~50% of amino, heavy metal borofluoride 0.5
~50%, amino alcohol 10~98% is thick liquid under the solder flux normal temperature state, it is difficult to the life for the solder stick containing scaling powder core
It produces, exists simultaneously other heavy metals, not environmentally.Number of patent application is that a kind of stainless steel flux patent of CN03116530.3 is retouched
It has stated stainless steel flux and chlorination is added using phosphoric acid as deoxidation agent using phosphoric acid, zinc chloride, ammonium chloride and water composition
Zinc and ammonium chloride are that tin and stainless steel form alloy-layer to reach welding purpose, although the Product jointing effect in welding
It is good, but using phosphoric acid as stripper, corrosivity is strong, and the residue after welding has corrosiveness, quilt around solder joint to stainless steel
Corrosion.
