従って、導電性物質の種類や使用量はプラスチック成形
品に導電性塗料を下塗り後、目的の塗料を上塗りして、
その表面固有抵抗が１０１２Ω以下になることを基準と
して選択し設計される。Therefore, the type and amount of conductive material to be used is determined by first coating the plastic molded product with conductive paint, then topcoating it with the desired paint.
It is selected and designed on the basis that its surface resistivity is 1012Ω or less.

の少量を使用する。The vehicle component used in the conductive paint is used to form the coating film necessary to fix the conductive substance to the surface of the plastic molded product, but a small amount is used so as not to reduce the conductivity.
ビヒクル成分及び溶剤の種類は、主として対象成形品の
素材および上塗り塗料の種類によって選択される。The type of vehicle component and solvent are selected mainly depending on the material of the target molded article and the type of top coat.
ビヒクル成分としては塗料用樹脂特にアクリル樹脂が一
般的であるが、塗膜を形成すれば油脂、繊維素などでも
よい。The vehicle component is generally a coating resin, especially an acrylic resin, but oils, fats, cellulose, etc. may also be used if a coating film is formed.
溶剤としては酢酸ブチル、イソプロピルアルコールなど
が一般的である。Common solvents include butyl acetate and isopropyl alcohol.
導電性塗料は溶剤形が一般的であるが、場合によっては
水溶性塗料、エマルジョン形塗料、無溶剤形塗料、粉体
塗料、溶着形塗料などにして使用してもよい。The conductive paint is generally in the form of a solvent, but in some cases it may be used in the form of a water-soluble paint, an emulsion paint, a solvent-free paint, a powder paint, a weldable paint, or the like.
水性塗料の場合は、有機溶剤は全く或いは少量しか使用
せず、水が溶剤的役割を果す。In the case of water-based paints, no or only a small amount of organic solvent is used, and water plays the role of a solvent.
又無溶剤形塗料、粉体塗料、溶着形塗料の場合は溶剤を
必要としない。Also, solvent-free paints, powder paints, and weldable paints do not require solvents.
導電性塗料中には必要に応じ前記以外の成分を加えても

ラスチック成形品に散布、被覆した後、塗料を塗装する
ことも考えられるが、微粉末の均一な被覆や付着が困難
であるので適当ではない。Instead of using conductive paint, it may be possible to spray and coat the above-mentioned conductive substance fine powder directly onto the glass molded product and then apply the paint, but it is difficult to uniformly coat or adhere the fine powder. It's not appropriate.
本発明はプラスチック成形品に導電性塗料を塗装した後

。Although the basic painting process of the present invention is to apply a conductive paint to a plastic molded product and then apply a top coat, the coating may vary depending on the type of raw material resin of the molded product, coating conditions, product type, etc. The process may be changed appropriately.
例えば付着性の悪い成形品に対して用いる付着性改良の
ための表面処理剤中に導電性物質を添加して、表面処理

Regarding the modified polyolefin resin described in the specification of No. 878, the patent application No. 1987-1987 related to the invention of the present inventors et al.
After treatment with the surface treatment agent described in the specification of No. 236, a conductive paint is applied. Fine powder of the conductive substance is dispersed in the surface treatment agent, and surface treatment to improve adhesion and conductivity are performed. It is also possible to perform the feeding at the same time, which is preferable because the step is omitted.

An electrically conductive substance may be added and dispersed in the composite polyolefin surface coating material for molded articles described in the specification, and this may be used as an electrically conductive paint.
導電性塗料の塗装方法は、刷毛塗り、スプレー塗り、浸
漬塗り、流し塗り、その他の何れでもよい。The conductive paint may be applied by brushing, spraying, dipping, flow coating, or any other method.
塗装は約３〜５μの膜厚に外観的にむらなく塗装するこ
とを標準とし、この状態になれば上塗り塗装後の製品の
表面固有抵抗を概して１０１２Ω以下にし得る。The standard is to apply the coating to a film thickness of about 3 to 5 .mu.m evenly in appearance, and under this condition, the surface resistivity of the product after the top coat can be generally reduced to 10@12 Ω or less.
導電性塗料を塗装して乾燥後、目的とする塗料を塗装す
る。After applying the conductive paint and drying it, apply the desired paint.
導電性塗料塗装塗膜の帯電防止性は長期間永久的に維持
されるので、乾燥後直ぐに上塗りしないで、経時後上塗
りしても製品の帯電防止効果が得られる。Since the antistatic property of the conductive paint film is maintained permanently for a long period of time, the antistatic effect of the product can be obtained even if the product is not overcoated immediately after drying but is overcoated after a period of time.
塗装製品の帯電防止は、塗膜の表向固有抵抗と膜厚によ
って影響される。The antistatic properties of painted products are affected by the surface resistivity and film thickness of the paint film.
表面固有抵抗が高いとき、或いは塗膜が厚いときは効果
が少ない。It is less effective when the surface resistivity is high or when the coating film is thick.
従って帯電防止性に関しては、表面固有抵抗の低い塗膜
を形成する塗料を選択し、又出来るならば塗膜厚を薄く
することが望ましい。Therefore, with regard to antistatic properties, it is desirable to select a coating material that forms a coating film with low surface resistivity, and to reduce the coating thickness if possible.
上塗りする塗料の塗装方法は追ｊ毛塗り、スプレー塗り
、浸漬塗り、流し塗り、後記の電気的塗装法、その他の
何れでもよい。The coating method for the top coat may be any of the following methods: additional coating, spray coating, dipping coating, flow coating, electrical coating method described later.
塗装時は成形品が帯電防止されているので埃りが着かず
作業が容易で仕上りは極めて良好である。During painting, the molded product is anti-static, so no dust will stick to it, making the work easy and the finish extremely good.
上塗り塗装後得られた塗装製品は、上塗り前の素地に埃
りが着いていないので外観が非常に美しく、又表面は永

塗装プラスチック製品に比し、非常に埃りが着きにくく
、又たとえ埃りがついても、はたきまたは空気による払
い落し、あるいは掃除器による吸い取りなど乾式の除去
方法により容易に除き得るので、商品価値が高い。The coated product obtained after the topcoat has a very beautiful appearance because there is no dust on the base before the topcoat, and the surface is permanently antistatic, so even if it is left for a long time, it will not be as good as conventional coated plastics. Compared to other products, it is extremely difficult for dust to adhere to it, and even if it does get dusty, it can be easily removed by dry removal methods such as dusting or blowing it off with air, or sucking it up with a vacuum cleaner, so it has a high commercial value.
帯電防止効果をしらべるために、塗装製品の表面を毛織
布で摩擦後、煙草の灰に接近させて灰の附着により表面
の帯電性を調べる煙草の灰附着試験でも灰の吸引付着が
無い。In order to examine the antistatic effect, a cigarette ash adhesion test was conducted in which the surface of a coated product was rubbed with a woolen cloth and then brought close to cigarette ash to determine the electrification properties of the surface by the adhesion of ash, and there was no ash adhesion.

ことが可能である。Molded products coated with conductive paint or overcoated have a lower surface resistivity and are conductive, so they can be coated with electrostatic coating or electrodeposition, which is difficult to do with general untreated plastic molded products. It is possible to perform electrical coating such as painting or electrostatic powder coating.

欠点がなく有用である。Conventionally, liquid surface treatment agents have been used in electrostatic painting to impart conductivity to plastic molded products, but these treatment agents generally have a dry or dry surface.
However, it was inconvenient to handle, as it had poor adhesion and durability, and for example, if it touched the treated surface, the attached treatment liquid would fall off and become ineffective, and it would have to be painted immediately after treatment. Molded articles endowed with electrical conductivity are useful without these drawbacks.
従って本発明にはこれらの電気的塗装を行なうために、
本発明の製造方法を利用し得るという効果がある。Therefore, in order to perform these electrical coatings, the present invention includes:
