【発明の詳細な説明】 ［産業上の利用分野］ 本発明は導電性塗料組成物に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to conductive coating compositions.

電性を付与させたのち、このものに上塗り塗料組成物を
静電塗装することが、一般に行なわれている。[Prior art and its problems] Conventionally, a conductive coating composition is applied to a non-conductive coating material such as an inorganic material or plastic to impart conductivity to the surface of the non-conductive coating material. It is common practice to electrostatically apply a top coat composition to a surface.
該導電性塗料組成物としては、例えばアミノアルキド系

ラーに金属を被覆した導電性フィラー等の導電性顔料を
混合分散したものが知られている。The conductive coating composition includes resins such as aminoalkyd resins and aminoacrylic resins; metal powders such as stainless steel, tin, copper, and aluminum; metal oxides such as zinc oxide, mica, silica, etc. It is known to mix and disperse a conductive pigment such as a conductive filler in which a non-conductive filler is coated with a metal.

も使用量を少なくして導電性に優れた塗膜を得ることは
困難である。However, since metal powders themselves have low electrical resistance, they can be used in small amounts, but their high prices make them impractical.Also, their high specific gravity makes it difficult to use resin during paint storage. It separates from the components and settles and aggregates at the bottom of the container. Furthermore, during long-term storage, this material causes hard caking, making it difficult to redisperse it to its original state even with stirring, and as a result, the metal powder content decreases. The disadvantage is that a coating film with a small amount of carbon is formed and the electrical conductivity of the coating film is poor. On the other hand, when metal oxides are used, they themselves have higher electrical resistance than metal powders, so if you try to obtain a coating film with the same electrical conductivity as metal powders, you will need to use a large amount, which results in stable paint storage. It has the disadvantage that the properties of the conductive filler and the physical properties of the coating film are deteriorated, and it is also difficult to obtain a coating film with excellent conductivity by reducing the amount of conductive filler used.

塗膜との付着性に劣るという欠点がある。Furthermore, conductive pigments such as conductive carbon and flaky graphite are also known to enhance conductivity. The conductive carbon is usually mixed and dispersed in the paint using a dispersion mill such as a ball mill or sand mill.During this dispersion, if the conductive carbon is dispersed close to the primary particles, the conductive carbon particles will be mixed and dispersed. There is a disadvantage that a coating film is formed with little contact between the layers, resulting in poor conductivity of the coating film, and if the amount of the conductive carbon is increased to increase the conductivity, the physical properties of the coating film are inferior. be. On the other hand, if the conductive carbon particles are not sufficiently dispersed and a large number of agglomerated conductive carbon particles are allowed to exist, there is a drawback that the paint storage property is poor and the finished appearance of the paint film is also poor. In addition, scaly graphite can form a coating film with excellent conductivity even when used in a small amount compared to conductive carbon, but it has particularly poor adhesion to plastic objects and adhesion to top coats. It has the disadvantage of being inferior to

A coating composition containing a conductive pigment in combination with scaly gelaphite has excellent storage stability and forms a coating film with excellent adhesion to objects to be coated and topcoat coatings and excellent conductivity.

The content of conductive carbon black is less than 40% by weight, and the content of conductive carbon black is less than 40% by weight.
If the blending ratio of scaly graphite exceeds 60% by weight, it is undesirable because the adhesion to the object to be coated and the top coat will decrease.On the other hand, if the blending ratio of conductive carbon black exceeds 60% by weight, the scale-like graphite If the blending ratio is less than 40% by weight, the physical properties of the coating film will deteriorate, which is not preferable.

好ましくない。In addition, the conductive carbon black powder has a DBP oil absorption of 70 to 250 cc/100 g, preferably 10
Within the range of 0 to 200cc/100g, electrical resistivity is 1Ω
- Cm or less, preferably 0. It is preferable to use one within the range of 1Ω·Cm or less. DBP oil absorption is 70cc/
If the DBP oil absorption amount is less than 100 g, a large amount of conductive carbon black is required to increase the conductivity of the coating film, which may deteriorate the physical properties of the coating film, which is undesirable. On the other hand, if the DBP oil absorption amount is greater than 250 cc/100 g, This is undesirable because it tends to reduce the storage stability of the paint and the finished appearance of the topcoat film.Also, if the electrical resistivity is larger than Ωcm, the amount used will be large and the paint will not be stored properly. This is not preferable because the stability and physical properties of the coating film tend to deteriorate.

い合うように配向させる働きによるものと推察される。[Operations and Effects of the Invention] In the present invention, when conductive carbon black and scale-like graphite are used together and are blended in a certain proportion, scale-like graphite is added to the chain structure of the conductive carbon black or a strafture having a chain-like structure. Since these conductive pigments are present in the paint composition in an aggregated form, there is no fear that these conductive pigments will separate or settle from the resin component, resulting in excellent long-term paint storage stability. The conductive carbon black and flaky graphite in the paint film formed from this material have the same structure as above, and since these things are interconnected, the conductivity of the paint film is improved. It is possible to efficiently express the enhancing effect. Although the action of the cellulose derivative is not clear, it is presumed that it serves to orient the scale-like graphite so that the scale-like plane faces the surface of the object to be coated during the drying process of the coating film.
このことによって鱗片状同志の接触も多く行なわれる様
