のが使用されていた。(Prior art and its problems) Conventionally, as a dust collecting electrode plate provided in an electric dust collector such as an air cleaner, a thin resin substrate is used from the viewpoint of compacting the dust collecting space and improving the dust collecting efficiency. The one coated with a conductive material such as carbon was used as a dust collecting electrode and a counter electrode, and a large number of these were alternately arranged at a minute interval.

ている。However, the electric dust collector-type air cleaner often uses a rental system in which only the filter unit equipped with the dust collecting electrode plate is replaced after several weeks of use. Take out the dust collecting electrode plate from the filter unit, clean the dust collecting electrode plate by dust, and reuse. For the dust collecting electrode plate,
Not only so-called normal dust, but also tars of cigarettes and fine oil droplets generated during cooking are often strongly adhered, and harsh cleaning conditions must be used for cleaning the dust collecting electrode plate. I don't get. Therefore, the conductive substance applied on the resin substrate is peeled off or thinned by washing again, which has an economical drawback that the dust collecting electrode plate has a short life.

しく延長することが可能になる。By using the lipophilic conductive coating as the undercoat layer, strong adhesion to the resin substrate can be obtained, and
By providing an oil-resistant conductive coating material containing a resin component having adhesiveness to the undercoat layer as a topcoat layer on the undercoat layer, the topcoat layer is a kind of protective coating film for the conductive coating film. It also acts as a permeation barrier, preventing the above-mentioned cigarette tar and fine oil droplets from invading or firmly adhering to the coating film. Prevents the film from swelling or softening. Thus, according to the invention,
Even if the cycle of use as an electrode plate and regeneration by washing is repeated many times, thinning due to abrasion of the conductive coating film and peeling of the coating film can be effectively prevented, and the life as an electrode plate can be remarkably extended. It will be possible.

付着保持作用が安定且つ確実に行われるものである。In addition, since both the undercoat layer and the topcoat layer are made of a conductive paint and the adhesion between both layers is remarkably good, a voltage can be easily applied to the entire surface of the electrode to be charged. The electrostatic trapping action and the dust holding action of dust and other air pollutant particles are stably and reliably performed.

至50:50の重量比にある。The lipophilic coating used for the undercoat layer preferably contains the same type of resin as the resin sheet from the viewpoint of adhesiveness, and from this point, an olefin resin is preferably used. Furthermore, although not the same type, acrylic resins can also be preferably used. A suitable lipophilic paint contains an olefin resin and an acrylic resin. In this case, the olefin resin component in the coating film is a lipophilic component and acts to enhance the adhesiveness to the olefin resin substrate, while the acrylic resin enhances the dispersibility of the conductive carbon in the paint. Acts like. As an olefin resin,
From the viewpoint of compatibility or dispersibility in coating materials, low molecular weight polypropylene and acid-modified polypropylene such as maleic anhydride grafted polypropylene and acrylic acid grafted polypropylene are used. On the other hand, as the acrylic resin, (meth) acrylic acid esters such as ethyl acrylate and methyl methacrylate are the main constituent components, and in addition, ethylenically unsaturated carboxylic acids such as acrylic acid, methacrylic acid and maleic anhydride; Hydroxyalkyl (meth) acrylates such as hydroxyethyl (meth) acrylate and hydroxypropyl (meth) acrylate; aminoethyl (meth) acrylate, (meth) acrylic acid-N
-Acrylic resins containing polar group-containing monomers of (meth) acrylic acid aminoalkyl esters such as aminoethylaminoethyl are used. The proportion of the olefin resin and the acrylic resin in the lipophilic paint is generally in the weight ratio of 2:98 to 50:50.

Are better. The top coat layer does not need to contain an ordinary olefin resin, but an amount smaller than the olefin resin content of the undercoat layer, for example, 1/2 or less, and particularly 1/3 or less, is used. There is no problem in including it.

When the amount of the conductive substance is more than the above range, the conductive substance is likely to be peeled off by frequent use and cleaning, and when the amount of the conductive substance is less than the above range, the electric resistance of the coating film is high, and the conductive air is contaminated. Adhesion of dust and dirt to the air will worsen and it will no longer function as an air cleaner. The electric resistance of the coating film is generally in the range of 0.1 to 10 KΩ.

On the other hand, by providing an oil-resistant conductive paint containing a resin component that exhibits adhesiveness as a top coat layer, this becomes a barrier, and even if the cycle of regeneration by use as an electrode plate and washing is restored many times, a conductive coating film is obtained. It is possible to effectively prevent thinning and peeling of the coating film due to wear of the electrode, and it is possible to significantly extend the life of the electrode plate.
