AI Technical Summary
Technical Problem
Existing AMB slurries are prone to oxidation when prepared in an atmospheric environment, leading to poor solder joints or increased voids at the solder interface, which affects the soldering quality. In addition, the preparation process is complex and costly.
Method used
A multi-layered, multi-mechanism dense protective layer is formed by combining inorganic nano-antioxidants and organic composite antioxidants. Through the synergistic effect of physical shielding and chemical chelation, the oxidation of metal powder is inhibited, enabling reliable preparation under atmospheric conditions.
Benefits of technology
It significantly reduces production costs and process complexity, ensures welding quality, and improves welding reliability and oxidation resistance.

Abstract
本发明涉及一种金属钎焊浆料，原料组分按100％质量，包括：抗氧化金属粉体80‑90％、有机载体10‑20％；所述抗氧化金属粉体包含0.1‑3％的无机纳米抗氧化剂和0.5‑10％的复合抗氧化剂，余量为金属粉体；所述复合抗氧化剂由有机膦酸类化合物和聚羧酸类聚合物组成。由此，本发明通过无机纳米抗氧化剂与有机复合抗氧化剂的协同作用，能够在金属粉体表面形成多层次、多机制的致密保护层，从而有效抑制金属粉体的氧化，进而能够在无须真空或惰性气体保护的大气环境下实现活性金属钎焊浆料的可靠制备，显著降低了生产成本和工艺复杂性。
