Problems solved by technology

However, if the quality of the copper layer is poor or the humidity of the storage environment is high, it is easy to oxidize and rust the copper layer on the surface of the welding wire, so that the welding wire cannot be used and will be scrapped.
[0003] Existing copper-plated welding wire polishing liquid or anti-rust liquid is mainly composed of vegetable oil and mineral oil, and its preparation method is to boil a single oil or mixed oil. Poor performance, easy to rust, etc.

Abstract

The invention provides a copper-plated solid-core welding wire polishing solution and a preparation method thereof. The welding wire polishing solution is mainly prepared from 800-1200 parts of base oil, 2-5 parts of 1H-Benzotriazole, 2-6 parts of alcohol, 8-10 parts of potassium stearate, 5-8 parts of sodium dodecyl sulfate and 50-100 parts of copper powder. The preparation method comprises the following steps: firstly, dissolving the 1H-Benzotriazole in alcohol; then adding the sodium dodecyl sulfate, the potassium stearate and the copper powder to obtain a mixture; stirring the mixture for 4-6 minutes; adding the mixture in the base oil to obtain a mixed solution; fully and uniformly stirring the mixed solution; and standing for over 24 hours, wherein if no layering occurs, the obtained solution is the welding wire polishing solution. When in use, the polishing solution is placed in a polishing die box, and a copper-plated welding wire can be used after being polished through the die box. By virtue of the polishing solution, the problems of easily rusting surface and poor electrical conductivity of a copper-plated solid-core welding wire are solved.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a welding wire polishing liquid and a preparation method thereof. Background technique [0002] At present, the manufacturing technology of copper-plated solid wire in China is basically mature. A 0.2-0.3 micron-thick copper layer is plated on the surface of the wire by replacing copper plating. One of its main functions is to prevent the wire from rusting. conductivity. However, if the quality of the copper layer is poor or the humidity of the storage environment is high, it is easy to oxidize and rust the copper layer on the surface of the welding wire, so that the welding wire cannot be used and is scrapped. [0003] Existing copper-plated welding wire polishing liquid or anti-rust liquid is mainly composed of vegetable oil and mineral oil, and its preparation method is to boil a single oil or mixed oil. Poor performance, easy to rust, etc. Contents of the inv...
