Problems solved by technology

This not only affects the use, but also causes a waste of tin; secondly, the alloy structure is not meticulous, the solder joints have no luster after welding, the weld seam is not smooth enough, and the surfacing layer is easy to crack, which affects the appearance of solder joints
Finally, the fluidity is poor, and it is easy to cause cusps and bridging after welding, which affects the welding quality

preparation Embodiment 1

[0021] Weigh 30g of Sb, 13.5g of Cu, 60g of Bi, 300g of nickel-tin alloy, 150g of tin-gallium, phosphorus and tin alloy, and 2386.5g of tin. Then put the tin into a steel container, move the steel container on an electric furnace, and heat it to 360°C to melt the tin into a liquid state. Add the weighed Sb, Cu, and Bi and stir for 30 minutes to melt the Sb, Cu, and Bi. Add the nickel-tin alloy and stir for 8 minutes. Add gallium, phosphorus, tin alloy and stir for 8 minutes. Pour the above stirred solder into the mold to get the finished product.

preparation Embodiment 2

[0023] Repeat Example 1 with the following differences: move the steel container on the electric furnace and heat it to 250° C. to melt the tin into a liquid state. Add the weighed Sb, Cu, and Bi and stir for 60 minutes to melt the Sb, Cu, and Bi. Add the nickel-tin alloy and stir for 12 minutes. Add gallium, phosphorus, tin alloy and stir for 12 minutes.

preparation Embodiment 3

[0025] Repeat Example 1, with the following differences: move the steel container on the electric furnace and heat it to 310°C to melt the tin into a liquid state. Add the weighed Sb, Cu, and Bi and stir for 45 minutes to melt the Sb, Cu, and Bi. Add nickel-tin alloy and stir for 10 minutes. Add gallium, phosphorus and tin alloy and stir for 10 minutes.

Abstract

The invention discloses an environmental protective high-temperature oxidation resistance welding material, which comprises the following parts: 0.1-2% Cu, 0.01-2% Sb, 0.01-1% Ni, 0.01-0.5% P, 0.01-0.5% Ga and Sn.

Description

Technical field: [0001] The invention relates to the field of welding technology, in particular to an environment-friendly high-temperature anti-oxidation solder, which has good anti-oxidation ability under high-temperature welding conditions. technical background: [0002] The traditional solder is Sn-pb alloy solder, which has superior physical and mechanical properties and is widely used in the soldering of electronic components. However, traditional solder contains a large amount of lead, which is a toxic metal element. Accumulate in the human body but cannot be excreted, and have serious harmful effects on the human body. Studies have pointed out that lead can strongly combine with protein in the human body to inhibit the normal function of the human body, causing neurological and metabolic dysfunction, and can cause hemoglobin reduction, anemia, hypertension and other diseases. During the production and use of lead-tin solder, the human body will inevitably ingest exc...
