Description
Technical field
The present invention relates to a kind of metallic film capacitor end face metal spraying no-lead gold spraying material, is a kind of zinc alloy specifically, relates to Alloy Materials field.
Background technology
Metallic film capacitor (calling electrical condenser in the following text) is the important component part of electronic devices and components, and relies on its good electrician's performance to become multiple industries such as high-speed railway, hybrid vehicle, wind-power electricity generation, solar electrical energy generation indispensable electronic component that updates.Once the capacitor end surface metal spraying material being widely used is five yuan of lead base gold spraying materials, in the unleaded upsurge in the whole world, by no-lead gold spraying material, is substituted.Existing no-lead gold spraying material is generally take red brass as main.Consider the factors such as the finiteness of resource and production cost, electrical condenser gold spraying material field is along with the development of technology, and progressively adopting pure zinc to substitute tin red brass is main gold spraying material.But pure zinc in use exists the phenomenons such as end face gilding layer particle is thick, tissue distribution is inhomogeneous, cause the loss angle of electrical condenser large, electrical condenser yield rate is not high.
Zinc is inferior to iron, aluminium and copper, the metal of the 4th " common ", aboundresources, low price and the element that can not work the mischief to environment and human body etc.In recent years, people for reduce electrical condenser production cost, zinc-base material has been carried out to very many-sided research in the application in this field, and obtained a lot of achievements.The Chinese patent of number of patent application 02111556.7 discloses a kind of Zn-Al alloy wire and preparation method thereof, solved the leaded problem of material, improve intensity, end face sticking power, electrical and thermal conductivity, weldability and the qualification rate of material, and provide metal spraying base mateiral for the electrical condenser of hot operation.The Chinese patent of number of patent application 02160539.4 discloses a kind of Zn-Al alloy wire and uses thereof, this zinc-aluminium silk is by the rare earth of interpolation 0.01%～0.05% and 0.05%～0.15% copper, for thermal spraying apparatus surface, there is better corrosion resistance nature compared with pure zinc silk, fine aluminium silk.The Chinese patent of number of patent application 200310105106.X discloses a kind of thermospray Zinc-aluminum alloy wire and preparation method thereof, by adding any or its combination in 0.006%～1.5% mishmetal, magnesium, titanium or boron, improve corrosion resistance nature, increase the service life.But some problems that above-mentioned patent documentation all fails to exist while solving capacitor end surface metal spraying completely: the phenomenon that particle is thick, tissue odds is even, the yield rate of electrical condenser still has the potentiality of further raising simultaneously.Along with the growing interest of electrical condenser production to production cost and product performance, industry wishes to have the better zinc alloy material of a kind of cost performance to emerge.
Summary of the invention
The object of this invention is to provide a kind of a kind of zinc alloy no-lead gold spraying material that can effectively improve capacitor end surface gilding layer quality, to improve the electrical contact performance of gilding layer and plastics film metal plating, reduce condenser loss angle, improve electrical condenser yield rate.
The technical solution used in the present invention is: a kind of zinc alloy, it is characterized in that each component composition is respectively by weight percentage: copper 0.005～1.0%, and/or titanium 0.01～0.08%, and/or manganese 0.001～0.01%, and/or praseodymium 0.005～0.1%, and impurity lead≤0.01%, cadmium≤0.002%, content of impurities≤0.02%, surplus is zinc.
The present invention is as further improvement, and the component of described alloy also comprises aluminium 0.01～0.1% by weight percentage.
Copper in the present invention's composition, research shows, in pure zinc, adds copper, can effectively improve the yield rate of electrical condenser, it adds weight percentage and is preferably 0.02～0.5%;
Titanium elements in the present invention's composition, research shows, in pure zinc, adds titanium elements, can effectively improve the yield rate of electrical condenser, titanium adds mass percent and is preferably 0.02～0.06% in pure zinc;
Manganese element in the present invention composition, research shows, when the copper content that adds in pure zinc is higher, adds micro-manganese element and also can obviously improve the yield rate of electrical condenser, in zinc alloy, the interpolation mass percent of manganese is preferably 0.003～0.007%;
The present invention forms further interpolation aluminium element, and research shows, adds micro-manganese element simultaneously, add again micro-aluminium element, both actings in conjunction, can further improve the yield rate of electrical condenser, and in zinc alloy, the interpolation mass percent of aluminium is preferably 0.01～0.1%;
Praseodymium element in the present invention's composition, research shows, adds praseodymium element in zinc alloy, can effectively improve the yield rate of electrical condenser, but along with improving the addition of praseodymium element, its DeGrain, therefore the interpolation weight percentage of praseodymium is preferably 0.005～0.08%;
The present invention improves the combinations of element more in pure zinc by adding micro-copper or copper, titanium, manganese, aluminium and praseodymium etc., through multi-party verification, show, can refinement gilding layer particle, effectively eliminate particle thick, improve the shortcomings such as tissue odds is even, improved the yield rate of electrical condenser.
Research shows, the trace element that the present invention adds, in scope of design of the present invention, can not produce detrimentally affect to metallic film capacitor.
