Abstract

The invention discloses a no-cleaning flux for lead acid battery manufacturing. The flux is prepared by mixing the following components in percentage by mass: 40-50% of ethanol, 30-40% of rosin, 4.0-8.0% of castor oil, 0.3-1.0% of surface active agent, and the balance of ultrapure water. The prepared flux is enough in surface activity, and is suitable for welding various lead alloy components; andresidues are hardly remained on the surfaces of welding lines after welding, so that cleaning is not needed after welding. Even if few residues are on the surfaces of the welding lines, cleaning is not needed; and the residues are stable in property, so that corrosion cannot occur. As the flux has excellent characteristics, when the flux is applied to lead acid battery busbar and polar lug welding, the welding quality can be prominently improved, the auxiliary workhour is greatly reduced, and the environmental pollution problem is prevented.

Description

technical field [0001] The invention relates to a flux, in particular, the invention relates to a no-cleaning flux, especially a no-cleaning flux used in the manufacture of lead-acid batteries. Background technique [0002] The built-in bus bar of the lead-acid battery is equipped with tabs, and the protruding tabs are connected to the bus bar by welding. Both the bus bar and the lug are lead alloy components. The surface of this lead component is easy to produce oxide film in the natural environment, and the heat-resistant oxide film is not conducive to the formation of weld seam during welding. Therefore, appropriate flux must be added during the welding process of the busbar and tabs, and qualified welding quality can be obtained under the action of the flux. Soldering flux is a compound agent. In addition to evaluating the fluxing performance during configuration, environmental protection issues during the welding process must also be considered, especially whether the ...
