Abstract
A soldering Sn-Zn wire is prepared from Sn (48-82 wt.%), Zn (rest) and impurities (0-0.05) through proportionally adding Sn and Zn, smelting, and drawing several times. It is used for spraying it on the end face of metallized film capacitor. Its advantages are no lead, and high strength and ductility of welded seam.
Description
Technical field
The present invention relates to a kind of Welding Sn-Zn material and preparation method thereof, belong to the red brass technical field of material that is used for the spraying of electrical equipment discrete device metallic film capacitor end face.
Background technology
The spray metal material of the metallic film capacitor end face that has been widely used, typical in five yuan of gold spraying materials of lead base, the composition of its each component is by weight percentage: Sn37-39%, Zn 3-6%, Sb 0.5-1.5%, Bi 0.1-0.5%, all the other are Pb, though five yuan of gold spraying materials of this lead base have good end face adhesive force, superior welding performance, fusing point is low, 1KH, 10KH high-frequency test loss angle is little, but its lead tolerance is up to 53-59.4%, and lead has strong toxicity to human body, in a single day plumbous being absorbed by the body just gathered and can not be excreted naturally in vivo, if the lead concentration in the blood of human body surpasses 10 μ g/dl, will to the people in desperately, in addition, plumbous gathering easily causes the children's intelligence decline, and leaded discarded object also can contaminated soil and water source.
Summary of the invention
The purpose of this invention is to provide a kind of Welding Sn-Zn material and preparation method thereof with more satisfactory welding performance and electricapparatus performance.
The present invention is a Welding Sn-Zn material, comprises tin, and zinc etc. is characterized in that the composition of each component is by weight percentage: tin (Sn) 48-82%, all the other are that zinc (Zn) and total amount are not more than 0.05% impurity.
The composition of described each component can be preferably by weight percentage: tin (Sn) 58-72%, all the other are that zinc (Zn) and total amount are not more than 0.05% impurity.
The composition of each component can be by weight percentage in the described impurity: iron (Fe)＜0.01%, silicon (Si)＜0.01%, plumbous (Pb)＜0.03%.
The preparation method of Welding Sn-Zn material of the present invention is: add metallic tin and zinc by proportioning earlier, uniform ingredients and satisfactory alloy liquid draw the outlet base continuously in being higher than 100 ℃ of scopes of liquidus temperature, the line base is dialled into the Welding Sn-Zn material filament through repeatedly drawing again.
The solidus temperature of described Welding Sn-Zn material can be 198 ℃, and liquidus temperature can be 270-355 ℃.
The present invention is used for metallic film capacitor end face spray metal material, every electricapparatus performances such as its weld strength, ductility all are better than five yuan of gold spraying materials of existing lead base, so it is and unleaded nontoxic because of it, five yuan of gold spraying materials of fusing point and existing lead base are high slightly, only need do the technology parameter adjustment slightly, the metal spraying machine that can adapt to five yuan of gold spraying materials of most former use low melting point lead base uses.
The specific embodiment
Embodiment 1: the composition of each component is respectively by weight percentage: Sn 79-81%, all the other are Zn.
Embodiment 2: the composition of each component is respectively by weight percentage: Sn 69-71%, all the other are Zn.
Embodiment 3: the composition of each component is respectively by weight percentage: Sn 59-61%, all the other are Zn.
Embodiment 4: the composition of each component is respectively by weight percentage: Sn 49-51%, all the other are Zn.
The preparation method of the various embodiments described above is: add metallic tin and zinc by above-mentioned each proportioning earlier, uniform ingredients and satisfactory alloy liquid draw the outlet base continuously in being higher than 100 ℃ of scopes of liquidus temperature, the line base is dialled into the confidential Welding Sn-Zn material filament of asking of metal spraying through repeatedly drawing again.Control total impurities＜0.05%, wherein Fe＜0.01%, Si＜0.01%, Pb＜0.03% during preparation.
