Description

一种无腐蚀性的铝焊粉
技术领域
本发明涉及一种焊粉，具体是涉及一种无腐蚀性的铝焊粉。
背景技术
焊粉，是一种利用放热熔剂化学反应作为热源，产生高温并通过熔模而达到焊接目的的焊接方式所用的材料。现有的一些焊粉存在轻微腐蚀性的问题需要解决。
发明内容
本发明要解决的技术问题是克服现有技术轻微腐蚀性的缺陷，提供一种无腐蚀性的铝焊粉。
为解决上述技术问题，本发明提供以下技术方案：一种无腐蚀性的铝焊粉，按照重量百分比数计算，包括以下原料制成：HF：10～15％，K2CO3：5～ 10％，V2O5：7～26％，SnO2：0.5～8％，CaF2：2～6.5％，NaNO3：1.5～6.5％， Ni:0.5～3.7％，其余为铝粉。
进一步的，按照重量百分比数计算，包括以下原料制成：HF：15％，K2CO3： 10％，V2O5：25％，SnO2：6.5％，CaF2：5％，NaNO3：4％，Ni:3％，其余为铝粉。
本发明与现有技术相比具有的有益效果是：一种无腐蚀性的铝焊粉，使得铝焊粉无腐蚀性，焊后无需清洗，焊接稳定性好、密封性好、接头牢固、流动性好。
具体实施方式
实施例1
生产原料内增加HF和K2CO3，同时增添微量元素，更改配比比例，进而使得铝焊粉无腐蚀性，焊后无需清洗，焊接稳定性好、密封性好、接头牢固、流动性好。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
