（産業上の利用分野）
本発明は主にクリーンルームやＯＡ事務室などに用途が
ある帯電防止用化粧板の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing an antistatic decorative board that is mainly used in clean rooms, office automation offices, and the like.
（従来の技術）
帯電防止化粧板は精密加工業、食品加工業等において、
損傷や衛生上チリやホコリを嫌うクリーンルーム等の作
業所の壁材等用、さらに近年になって、ＯＡ事務室等の
壁材や間仕切り用としての使用が一般化している。(Conventional technology) Antistatic decorative boards are used in the precision processing industry, food processing industry, etc.
It has become common to use it as wall material in workplaces such as clean rooms where dirt and dust are averse to damage and hygiene, and in recent years, it has become commonplace to use it as wall material and partitions in OA offices.
従来から、これらの用途に使用される帯電防止化粧板の
製造方法としては、硅酸カルシウム板等の不燃板に接着
剤を介して紙を貼着しその上に導電性塗料を塗布し、乾
燥せしめる方法がある。Traditionally, the manufacturing method for antistatic decorative boards used in these applications has been to attach paper to a noncombustible board such as a calcium silicate board using an adhesive, apply conductive paint on top of it, and then dry it. There is a way to force it.
導電性塗料とはカーボンブラック、グラファイト、銀メ
ツキ微粒子等の導電性フィラーを多量に添加した塗料で
ある。この場合、導電性は高いが色調が悪い導電性塗料
を下塗りし、その上に比較的導電性は劣るが化粧性の良
い色調に調合した塗料を上塗りすることが必要である。A conductive paint is a paint to which a large amount of conductive filler such as carbon black, graphite, silver plating fine particles, etc. is added. In this case, it is necessary to apply an undercoat with a conductive paint that has high conductivity but poor color tone, and then top coat it with a paint that has relatively poor conductivity but has a good cosmetic color tone.
即ち下塗り塗料を塗布しこれを乾燥せしめた後に、上塗
り塗料を塗布しこれを乾燥させるという塗装工程と乾燥
工程とを２度繰り返す必要があるので、製造工程が複雑
になるのである。また下塗り塗料が多量の導電フィラー
を含有しているため、色調が黒ないし褐色を呈しており
美観上化粧性に欠けることから、その色調を隠蔽するた
め、さらに化粧性のある上塗り塗料を多量に塗布して隠
蔽性を確保する方法がとられているのである。That is, the manufacturing process becomes complicated because it is necessary to repeat the painting process and drying process twice, in which the undercoat is applied and dried, and then the topcoat is applied and dried. In addition, since the undercoat paint contains a large amount of conductive filler, the color tone is black or brown and lacks cosmetic properties, so in order to hide the color tone, a large amount of top coat paint with cosmetic properties is applied. The method used is to apply it to ensure concealment.
（発明が解決しようとする課題）
しかし、これらの帯電防止化粧板はなお導電性が充分で
なく、塗装と乾燥を繰り返すため製造工程が煩雑となり
、かつ塗料コストが高くなるという問題点がある。(Problems to be Solved by the Invention) However, these antistatic decorative boards still do not have sufficient conductivity, and the manufacturing process is complicated due to repeated painting and drying, and there are problems in that the cost of paint is high.
本発明の目的は帯電防止性に優れた帯電防止化粧板を簡
易に製造しかつ安価に製造することである。An object of the present invention is to easily and inexpensively produce an antistatic decorative board with excellent antistatic properties.

ことにより導電性塗膜又は非導電性塗膜を形成させるこ
とを特徴とする帯電防止化粧板の製造方法である。That is, the present invention is characterized in that a carbon fiber mixed paper is attached to a base material via an adhesive, and a conductive paint is applied thereon to form a conductive coating film or a non-conductive coating film. This is a method for manufacturing an antistatic decorative board.
本発明において使用し得る基材としては合板、中密度繊
維板、パーチクルボード等の木質板か硅酸カルシュム板
（以下硅カル板と云う）、セメント板などの無機質板を
挙げることかできる。Examples of the base material that can be used in the present invention include wood boards such as plywood, medium density fiberboard, and particle board, and inorganic boards such as calcium silicate board (hereinafter referred to as silica board) and cement board.
本発明に使用する接着剤としては、とくに制限はないが
、尿素系又はポリ酢酸ビニル、ポリビニルアルコール等
のビニル系樹脂からなる接着剤が特に好ましい。The adhesive used in the present invention is not particularly limited, but adhesives made of urea or vinyl resins such as polyvinyl acetate and polyvinyl alcohol are particularly preferred.

性能を有するものである。Carbon fiber mixed paper usually refers to paper made of carbon fiber alone or mixed with pulp, and the surface electrical resistance value of this white paper body usually has a conductive property of about 10' to 106 ohms.
非導電性塗料としてはアクリル系またはウレタン系樹脂
を塗料化したものをいう。The non-conductive paint refers to a paint made from acrylic or urethane resin.
また導電性塗料としては、アクリル系またはウレタン系
樹脂にグラファイト、銀メツキ微粒子等導電性フィラー

塗り塗料として１０’〜１０１２オ一ム程度に調整され
ている。Further, examples of the conductive paint include a paint obtained by mixing an acrylic or urethane resin with a conductive filler such as graphite or silver plating fine particles. The surface electrical resistance value of a coating film formed only with this paint can be adjusted by the amount of conductive filler added, but from the viewpoint of cosmetic properties, it is adjusted to about 10' to 1012 ohms as a top coat.
また帯電防止化粧板の表面の意匠性に応じて導電性塗料
に代えて非導電性塗料を用いることが可能である。この
場合、カーボンファイバー混抄ペーパー上に形成される
塗膜の厚さは１００ミクロン以下が好ましい。Moreover, it is possible to use a non-conductive paint instead of a conductive paint depending on the design of the surface of the antistatic decorative board. In this case, the thickness of the coating film formed on the carbon fiber mixed paper is preferably 100 microns or less.
さらに意匠性を表現するため、塗料の代わりに印刷イン
キを使用することも可能である。この場合も導電性のイ
ンキまたは非導電性のインキを使用することができる。Furthermore, in order to express the design, it is also possible to use printing ink instead of paint. Again, conductive or non-conductive inks can be used.
インキの場合塗布量は微量であるから、いずれのインキ
を使用しても塗膜の厚さの制限はない。Since the amount of ink applied is very small, there is no limit to the thickness of the coating no matter which ink is used.
表面電気抵抗値が高い上塗り塗料であっても表面電気抵

性能を持っていることがわかる。Even if the top coat has a high surface electrical resistance value, by combining it with carbon fiber mixed paper, which has a low surface electrical resistance value, the surface electrical resistance value as a decorative board can be 10.
"~108 ohm, and this value has electrical properties that make it difficult for dirt and dust to adhere to it, and fully satisfies the performance as an antistatic decorative board.An antistatic decorative board that is coated twice with conventional paint. The electrical resistance value is usually about 10'' to 108, indicating that the charged decorative board of the present invention has very excellent antistatic performance.
