ルバンなどに用いる複合制振鋼板の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a composite damping steel plate used for an electric product which is devised to suppress vibration noise and has low noise, for example, an electric washing machine body or an oil van of an automobile. Regarding improvement.
(従来の技術) 従来の複合制振鋼板は、第3図に示す如く鋼板1と鋼
板1′との間に振動音緩衝材2とプラスチックフィルム
等を装入し圧延加工して作られていた。(Prior Art) A conventional composite vibration damping steel sheet is made by loading a vibration damping material 2, a plastic film or the like between a steel sheet 1 and a steel sheet 1 'as shown in FIG. .
しかし、かかる複合制振鋼板3は、製品組立時通電性
の悪さから電気抵抗溶接がしにくく、十分な溶接強度が
得られない。However, the composite vibration damping steel plate 3 is hard to be subjected to electric resistance welding due to poor electrical conductivity at the time of product assembly, and cannot obtain sufficient welding strength.
この為複合制振鋼板3の振動音緩衝材2中に、第4図
に示す如くNi、Cu、Fe、Al、Agなどの通電性の良好な球
4を混合分散させ、電気抵抗溶接をし易くする試みがな
されている。Therefore, as shown in FIG. 4, spheres 4 having good electrical conductivity such as Ni, Cu, Fe, Al, and Ag are mixed and dispersed in the vibration damping material 2 of the composite vibration damping steel plate 3 and subjected to electric resistance welding. Attempts have been made to make it easier.
(発明が解決しようとする課題) ところで、Niは50〜150μmの球状にする為の加工に
おいて真球度が悪く且つ球径のばらつきが大きく、Cu、
Fe、Alは安価であるが球4の表面が酸化し易く、接触信
頼性に欠ける為十分な溶接強度が得られず、Agは高価で
経済性が悪い等の問題があった。(Problems to be Solved by the Invention) By the way, Ni has a poor sphericity and a large variation in sphere diameter in processing for forming a spherical shape of 50 to 150 μm, and Cu,
Fe and Al are inexpensive, but the surface of the sphere 4 is easily oxidized, so that sufficient contact strength is not obtained due to lack of contact reliability, and Ag is expensive and has poor economic efficiency.
そこで本発明は、製品組立時の電気抵抗溶接に於い
て、十分な溶接強度を得ることのできる複合制振鋼板を
提供しようとするものである。Accordingly, an object of the present invention is to provide a composite vibration damping steel sheet capable of obtaining a sufficient welding strength in electric resistance welding during product assembly.
(課題を解決するための手段) 上記課題を解決するための本発明の複合制振鋼板は、
鋼板と鋼板の間に装入された振動音緩衝材中に、Niを0.

る。(Means for Solving the Problems) The composite vibration-damping steel sheet of the present invention for solving the above-mentioned problems includes:
Ni is included in the vibration damping material inserted between the steel plates.
A steel sphere, a vibration-damping material, and a steel plate are rolled into a single body by disposing a copper sphere coated with 1 to 5 μm or a net woven from Ni or Ni alloy wire or Ni-coated wire.

されるCu球にNiを0.1〜5μm被覆する理由は、Cu球表
面の酸化を防止する為で、0.1μm未満ではその効果が
無く、5μmを超えると被覆作業に時間がかかって生産
性が悪くなるばかりで、酸化防止効果は変わりないもの
である。In the composite damping steel sheet of the present invention, the reason why Ni is coated on the Cu spheres disposed in the vibration sound absorbing material with 0.1 to 5 μm is to prevent oxidation of the Cu sphere surface, and the effect is less than 0.1 μm. When the thickness exceeds 5 μm, the coating operation takes a long time and the productivity is deteriorated, and the antioxidant effect remains unchanged.
Cu球にNiを被覆する手段としては、湿式めっき、環式
めっきの他にスパッタリング、蒸着でも良い。The means for coating the Cu spheres with Ni may be sputtering or vapor deposition in addition to wet plating and cyclic plating.

覆した複合線で編織したものであっても良い。また網状
体を編織する素線は丸線に限らず、角線でも良い。In the composite vibration-damping steel sheet of the present invention, the mesh arranged in the vibration-damping material is preferably woven with Ni or Ni alloy such as Cu-Ni alloy wire having good corrosion resistance and excellent electrical conductivity. However, the present invention is not limited to this, and may be woven with a composite wire in which a wire such as Cu or Fe is coated with Ni. Further, the element wire for weaving the net-like body is not limited to a round wire, but may be a square wire.
