【発明の詳細な説明】
［産業上の利用分野］
この発明は、導電性および割振性を有する塗料組成物に

磁波シールドと騒音防止を行なうことを目的とする塗料
組成物に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a coating composition having electrical conductivity and splitting properties. Specifically, the present invention relates to a coating composition that is applied to the inside of the housing of electrical equipment to provide electromagnetic shielding and noise prevention.
［従来の技術］
従来、電気機器の筺体に処理して、電磁波シールドと割
振を同時に行うには、導電性塗料と割振材の２種類の材
料を併用する以外に有効な方法はなかった。[Prior Art] Conventionally, there has been no effective method other than using two types of materials, a conductive paint and an allocation material, in combination to simultaneously shield and distribute electromagnetic waves by treating the housing of an electrical device.

成分を配合することにより、良好な割振性を有する塗料
もしくはシート状組成物である。A conductive paint is a paint that is made conductive by blending metal powder into the paint, and as a result has the function of blocking electromagnetic waves. The distribution material is a paint or a sheet-like composition that has good distribution properties by blending an active ingredient such as mica with a synthetic resin.

導電性を失うという問題があった。[Problems to be Solved by the Invention] The purpose of the present invention is to produce a coating composition that has both electrical conductivity and distribution properties. This method involves blending mica and metal powder at the same time. However, because mica has a high degree of insulating properties, it is adjacent. Insulate metal powder from each other,
There was a problem of loss of conductivity.
［問題を解決する為の手段］
本発明は、溶剤可溶性合成樹脂にニッケルコートマイ力
を配合することにより、前記問題を解決したものである
。[Means for Solving the Problems] The present invention solves the above problems by blending a nickel coat with a solvent-soluble synthetic resin.

チレンアクリル、ポリスチレン等の単独または共重合樹
脂は、比較的高い損失係数を有するので好ましい。エポ
キシ樹脂、ウレタン樹脂等の無溶剤系樹脂ペーストの場
合では、■粘度が高いために、スプレー塗工ができない
、へヶ塗りの場合にムラが生じる、■硬化時間が長い、
■可使用時間が短い等、硬化工程や塗工工程において作
業性に問題がある。また、水溶性合成樹脂の水溶液の場
合は、水がニッケルを酸化し、導電性を阻害する。The synthetic resin used in the present invention is preferably one that dissolves in an organic solvent. For example, single or copolymer resins such as acrylic resin, methacrylic resin, polyvinyl chloride, polyvinyl acetate, ethylene vinyl acetate, ethylene acrylic, and polystyrene are preferred because they have a relatively high loss coefficient. In the case of solvent-free resin pastes such as epoxy resins and urethane resins, ■Due to their high viscosity, spray coating is not possible; uneven coating occurs when applying; ■Curing time is long;
■There are problems with workability in the curing process and coating process, such as short pot life. Furthermore, in the case of an aqueous solution of a water-soluble synthetic resin, water oxidizes nickel and inhibits conductivity.
ニッケルコートマイカは、マイカにニッケルをコートし
たものであって、１０μｍから４００μｍの粒径を有す
るものが好ましい。１０μｍ未満では、制振性が低下し
、４００μｍ以上では、流動性が低く、ボッボッになる
ために均一に塗工できず、表面仕上も悪い。Nickel-coated mica is mica coated with nickel, and preferably has a particle size of 10 μm to 400 μm. If it is less than 10 μm, the vibration damping properties will deteriorate, and if it is more than 400 μm, the fluidity will be low and it will become lumpy, making it impossible to coat uniformly and giving a poor surface finish.
ニッケルコートマイカ中のニッケル分としては２０重量
％〜６０重量％の範囲が好ましい。２０重量％未満では
導電性を損ない、６０重量％以上では、制振性を損なう

料として使用できない。仮に塗工できたとしても、塗膜
がもろく割れやすくなるので、ニッケルコートマイカを
３００部以上配合することは、好ましくない。The nickel content in the nickel-coated mica is preferably in the range of 20% by weight to 60% by weight. If it is less than 20% by weight, conductivity will be impaired, and if it is more than 60% by weight, vibration damping properties will be impaired and dispersibility will also be poor. The blending amount of nickel coated mica is 50 to 30 parts per 100 parts of resin solid content.
It is preferably within the range of 0 parts. If it is less than this, allocability,
Both have low conductivity. If the amount is more than this, the viscosity decreases and it cannot be used as a paint. Even if coating is possible, it is not preferable to blend 300 parts or more of nickel-coated mica because the coating film will become brittle and easily cracked.

ことも可能である。Although other metals than nickel can be considered as the metal to be coated on mica, it is necessary to have high conductivity, and nickel is optimal. If you don't take cost into consideration, gold, silver,
Platinum and the like can also be used. Furthermore, it is also possible to improve electromagnetic shielding properties by treating the surface with humic acid.

カは割振性の向上に寄与する。[Function] - In the coating composition of the present invention, the surface of mica is covered with conductive nickel, so that mica, which originally acts as an insulating material, acts as a conductive material. Therefore, it has much higher conductivity than, for example, mixing mica and nickel powder in the same amount. Mica, which is the main component, contributes to improving the allocatability.

Furthermore, by suppressing the vibration of the casing, the generation of noise can be reduced.

の沈降も少ない。また、バインダーは溶剤性であるため
、乾燥性も良く、適当に希釈することにより、スプレー
による塗工も可能である。Furthermore, when comparing the true specific gravity of nickel and nickel-coated mica, nickel-coated mica is much lighter, so there is less metal powder settling, which is a problem with conductive paints mixed with metal powder. Furthermore, since the binder is solvent-based, it has good drying properties and can be applied by spraying if diluted appropriately.
