Abstract
Disclosed is a stainless steel soldering flux, which solves the problem that the former stainless steel can not make tin soldering. The invention is composed of phosphorous acid, zinc butter, ammonium chloride and water; use phosphorous acid as oxidant; the left viscous material after the phosphorous acid is evaporated at high temperature can adheres to the surface of the stainless steel to prevent the secondary oxidation; then add zinc butter and ammonium chloride, making tin and stainless steel to form alloy layer; and then the welding purpose is achieved. The invention not only can be used for tin soldering of the copper and iron, but also can be used for tin soldering of the stainless steel surface, the chromeplated surface and nickel-plated surface.
Description
Technical field
The present invention is a kind of scaling powder.
Background technology
The scaling powder that is used for the metal soldering at present has rosin, solder(ing) paste, hydrochloric acid etc., works the weldering effect that helps in the time of carrying out soldering to metals such as copper, iron.But stainless steel is because its molecular structure stabilized height is difficult for forming the alloy permeable formation with tin when heating and welding with it, and present various scaling powders can't be realized stainless soldering.
Summary of the invention
The object of the invention is to provide a kind of scaling powder that is used for the stainless steel soldering, connects to realize stainless soldering.
The present invention realizes goal of the invention like this: with middle strong acid phosphorus as the deoxidation agent, again because it at high temperature stays the surface of thick material after attached to the stainless steel acid treatment after the water evaporates, prevent secondary oxidation, add zinc chloride, ammonium chloride again, when welding, reach the purpose that makes tin and stainless steel form alloy-layer.The present invention is made up of phosphoric acid, zinc chloride, ammonium chloride, water, and its proportioning is (mass ratio):
Phosphoric acid 20%--30%
Zinc chloride 10%--15%
Ammonium chloride 10%--15%
Water 40%--60%
Advantage of the present invention is: can not only be used for the soldering of metals such as copper iron, also can be used for the soldering of stainless steel, plating, nickel, chrome-plated surface.
The specific embodiment
The invention will be further described according to embodiment below.
Embodiments of the invention adopt best proportioning to be (mass ratio):
Phosphoric acid 25%
Zinc chloride 12.5%
Ammonium chloride 12.5%
Water 50%
Wherein zinc chloride, ammonium chloride all adopt the solid state powder of chemical pure grade, and phosphoric acid adopts the chemical pure grade goods more than 95%.During preparation zinc chloride, ammonium chloride, phosphoric acid mixed and be stirred in the water fully that dissolving gets final product, be applied to object surface to be welded during use and carry out soldering, can obtain good welding effect.
