Abstract

본 발명은 Al F3, KF와 기타 첨가제를 포함하는 화합물에 Al, F, K를 포함시켜 수용성화합물로 만들고 미립자상태로 분쇄하며 건조분말 또는 습식분말상태로 건조시키되 Al F3: KF를 50-60중량% : 40∼0중량%로 조성하거나 Al : F : K를 1 : 4∼4.5 : 1.5의 부피비율로 조성시킴을 특징으로 하는 비부식성과 비흡습성이 우수한 알루미늄브레이징용 용제 및 그 제조방법이며, 본 발명에 의한 용제는 제조공정이 간단하여 저렴한 비용으로 만들 수 있고, 비부식성과 비흡습성이 우수하여 브레이징후 접합부위를 세척해주지 않아도 되며, 융점조정이 용이하여 응용범위가 넓고, 습식분쇄가 가능하여 미립자상태로 만들 수 있기 때문에 용제의 사용량을 절감시킬 수 있으며, 매끄러운 접합부위를 얻을 수 있는 장점을 나타낸다.The present invention comprises Al F 3 , KF and other additives, including Al, F, K to make a water-soluble compound, pulverized in the form of fine particles and dried in a dry powder or wet powder, but Al F 3 : KF 50- 60% by weight: 40 to 0% by weight or Al: F: K in a volume ratio of 1: 4 to 4.5: 1.5 of the non-corrosive and non-hygroscopic property of the aluminum brazing solvent and its manufacturing method The solvent according to the present invention can be made at a low cost by a simple manufacturing process, and excellent in non-corrosiveness and non-hygroscopicity do not need to clean the joint after brazing, easy melting point adjustment, wide application range, wet grinding Since it can be made into a particulate state, it is possible to reduce the amount of solvent used and to obtain a smooth joint.
