Problems solved by technology

In the existing soldering process, the fluxes used are mostly lead-containing or halogen-containing, which not only brings safety hazards to operators, but also endangers the surrounding environment and is not environmentally friendly; in addition, ordinary fluxes have no antibacterial effect. Ideal, long-term use will have some adverse effects on the fluxing effect

Description

technical field [0001] The invention belongs to the field of flux, in particular to an environment-friendly and antibacterial flux and a preparation method thereof. Background technique [0002] Welding process is one of the more common processes in machining. In the welding process, solder is often used, so that the two parts to be welded are connected together under the action of solder, and the quality of the solder will directly affect the quality of the entire welding performance. Welding processes include arc welding, oxygen welding, and tin welding. In the existing soldering process, the fluxes used are mostly lead-containing or halogen-containing, which not only brings safety hazards to operators, but also endangers the surrounding environment and is not environmentally friendly; in addition, ordinary fluxes have no antibacterial effect. Ideally, long-term use will have some adverse effects on the fluxing effect. Contents of the invention [0003] The technical ...
