    摘要: An aqueous aluminum brazing composition containing an organic binder and zinc-based flux which prevents precipitation of the zinc-based flux having a large specific gravity while securing excellent brazeability. The thixotropic index of the brazing composition is adjusted to 1.01-1.20 by adding (meth)acrylic acid/(meth)acrylate copolymer emulsion to the brazing composition as a precipitation inhibitor in an amount of 0.03-1.50 wt % of 100 wt % of the brazing composition. Since the (meth)acrylic acid/(meth)acrylate copolymer emulsion is used as the precipitation inhibitor in a specific amount instead of other types of compounds used for powder-containing paint such as ultrafine particle silica, poly(meth)acrylate, or polyvinyl alcohol, precipitation of the zinc-based flux can be prevented without impairing brazeability.

    摘要: The present invention is a water-based binder used when manufacturing aluminum brazed products such as engine radiators, condensers for car air conditioners, and the like. The water-based binder is obtained by saponifying an ester methacrylate polymer that has an acid value and a glass transition temperature within specified ranges. In the presence of an alcohol that is water soluble and volatile and has a flash point higher than a specified temperature, the brazing composition, in which this binder and flux and the like are mixed, does not have the risk of catching on fire or exploding and also has excellent wettability and can be uniformly coated onto an aluminum material. Furthermore, when a binder in which polyoxirane or polyoxazoline is added as a sub component to this ester methacrylate polymer, which is the main component, the room temperature adhesion of the brazing composition onto the aluminum materials is further improved, and thickening of this composition during coating or storage is also prevented.
