アルミニウムろう付用フラックスに関する。Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a novel brazing flux, and particularly to an aluminum brazing flux suitable for joining AQ or A2 alloy plates, pipes, and other structures. .

国特許第３９５１３２８号のフラックスニはＫＦとＡａ
Ｆ、＋７３弗化物を用いてろう付する方法が提案されて
いる。Conventionally, chloride-based fluxes have been commonly used for brazing AQ or Afi alloys, but they are highly hygroscopic and
If the residual flux after brazing is not completely removed, corrosion resistance will be significantly reduced. Removal of residual flux requires a cleaning step, which is expensive in terms of equipment. Furthermore, if the structure has a complex shape, complete removal is difficult. Recently, U.S. Pat.
A brazing method using F, +73 fluoride has been proposed.
これは吸湿性が大きいＫＦとＡ４Ｆ、と混合して溶融さ
せることによりに、ＡｎＦ’ｓとＫＡＱＦ。This is achieved by mixing and melting KF and A4F, which have high hygroscopic properties, and AnF's and KAQF.

被接合部材の耐食性を向上させるという点ではまだ欠点
があった。Create a compound of This compound has very low hygroscopicity;
It is said that it is not necessary to remove the residual flux that remains on the surfaces to be joined after brazing. However, even if there are no corrosive components in the residual flux, there is nothing that can improve corrosion resistance.
There were still drawbacks in terms of improving the corrosion resistance of the members to be joined.

により耐食性を向上させるろう付用フラックスを提供す
ることにある。The object of the present invention is to eliminate the need for removing black after brazing when joining using a brazing material such as AQ-8i, and to improve corrosion resistance by leaving a corrosion-resistant metal, especially Zn, on the surface to be joined. Our objective is to provide a brazing flux that improves the

性を有し、ろう付後の残渣フラックスを完全に除去しな
ければ耐食性を著しく低下させることになり目的に合致
しない。An essential condition for a flux that does not require removal after brazing is the absence of hygroscopic components in the residual flux. Non-hygroscopic fluxes often have fluoride-based components, and chloride-based components are generally used to remove oxide films on 80 and AΩ alloy members and increase wetting spread. . However, most of the chloride-based materials have hygroscopic properties, and if the residual flux after brazing is not completely removed, the corrosion resistance will be significantly lowered, which does not meet the purpose.

As a result of investigating the addition of various fluorides thought to be effective in improving corrosion resistance mainly to AQF and KF acid components, which have a suitable melting point when M is used, it was found that ZnF is the best.

った。In addition to Li, the addition components such as Na, Rb, Cs, Mg, and Ca are set to a range of 10% by weight or less so as not to increase the melting range of the flux, and adding more than that has little effect. This is because we have confirmed that there is no change. Furthermore, although the lower limit of the amount added varies slightly depending on the added components, it has been found through experiments that a content of 3% by weight or more of any component has an effect on wetting and spreading.

When n F is included, the melting point becomes 620°C or less, and even when this component is added to a component that has already melted at 26%, the melting point does not increase, resulting in brazing that has good wetting and spreading properties in terms of brazing temperature and excellent corrosion resistance. It turns out that a joint can be obtained.
