添加することによって、高い防錆防食性や耐滑性を具備
すると共に、導電性を保持して静電気事故に対する高い
安全性を有する、石油タンクの屋根用塗料等に用いられ
る導電性防食被覆組成物に関する。TECHNICAL FIELD The present invention relates to a conductive anticorrosion coating composition, and more specifically, by adding metallic zinc powder and a conductive powder having a certain particle size to a synthetic resin in a specific range, The present invention relates to a conductive anticorrosion coating composition used for a paint for roofs of petroleum tanks and the like, which has high rust prevention and anticorrosion properties and slip resistance, and which has high conductivity and high safety against electrostatic accidents.
［従来技術］ 石油タンクの屋根用被覆材としては、主に防錆防食を
目的として、各種の塗料が単独または数種を組合わせて
使用されている。[Prior Art] As coating materials for roofs of petroleum tanks, various paints are used individually or in combination of several kinds mainly for the purpose of rust prevention and corrosion prevention.
これらの塗料には、亜鉛末塗料が多く使用されている
が、ほとんどの場合は合成樹脂系上塗塗料との併用であ
る。Zinc dust paint is often used for these paints, but in most cases, it is used in combination with a synthetic resin-based topcoat paint.
また、特殊な場合として、部分的にステンレス板を溶
融で取り付けたり、金属亜鉛溶射により被覆をして防食
性、導電性を兼備させることも行なわれている。Further, as a special case, a stainless steel plate is partially attached by melting, or a metal zinc spray coating is performed so as to have both anticorrosion property and conductivity.
しかるに、石油タンクに使用される一般の塗料は防錆
防食機能面では問題はないが、本来、これらの被覆材は
絶縁被覆であるため、静電気が蓄積しやすく、石油タン
クの静電気火花による火災の危険性は改善されていな
い。However, although general paints used for oil tanks have no problem in terms of rust prevention and corrosion prevention, since these coating materials are originally insulation coatings, static electricity tends to accumulate, and fires caused by electrostatic sparks in oil tanks may occur. The risk has not improved.
また、亜鉛末塗料を単独で使用した場合、塗装初期の
被覆膜は静電気蓄積防止効果はあるが、長時間の暴露に

を付与するためケイ砂等を塗料に添加するが、このもの
には導電性がなく、やはり静電気による火災の危険性は
改善されない。In addition, when the zinc dust coating is used alone, the coating film at the initial stage of coating has the effect of preventing static electricity accumulation, but long-term exposure may cause the zinc dust coating surface to have insulative zinc corrosion products (white rust). If it occurs, its conductivity is impaired, and if it is applied to an oil tank, it will cause the same fire risk as above. If a large amount of this white rust is present on the surface of the coating film, if it contains a large amount of water due to rain or the like, it will be slippery when walking on it, and there is a risk of slipping accidents. Generally, silica sand or the like is added to the coating material in order to impart slip resistance, but this material has no electrical conductivity, and the risk of fire due to static electricity cannot be improved.
ステンレス板の溶接による取り付け等が既設石油タン
クの静電気防止策に実施されているが、火気を使用する
ため作業上の安全性が概念される。また金属亜鉛溶射等
も考えられるが、これらは亜鉛末塗料を単独で用いた上
記と同様な欠点を有しており、作業性、経済性の面でも
塗装と比較すると実用的とは言えない。Welding of stainless steel plates, etc. is carried out to prevent static electricity from existing oil tanks, but since fire is used, work safety is a concept. Although metal zinc spraying and the like are also conceivable, these have the same drawbacks as the above using zinc dust coating alone, and are not practical in comparison with coating in terms of workability and economy.

30 to 430 parts by weight of the conductive powder of 1. is added to the conductive anticorrosion coating composition.

レタン樹脂、アルキド樹脂等が特に好ましく用いられ
る。The synthetic resin used in the present invention is not particularly limited as long as it is a resin generally used in zinc dust paint, but from the viewpoint of durability, economy and coating workability, epoxy resin, urethane resin, alkyd Resin and the like are particularly preferably used.

鉛末濃度が高いため、導電性粉末の添加余地がなく、塗
膜強度も不充分であり本発明の目的は達成できない。The metallic zinc powder used in the present invention is one of the spherical powders and flake powders that have been conventionally used in paints.
Seeds or mixtures of these, and in small amounts
A zinc-based alloy powder containing Al, Mg, Ni, etc. may be used.
The amount of the zinc metal powder added is 450 to 900 parts by weight, preferably 600 to 850 parts by weight, based on 100 parts by weight of the solid content of the synthetic resin. If the amount of metallic zinc powder added is less than 450 parts by weight, the anticorrosive property will drop sharply, and if it exceeds 900 parts by weight, the concentration of metallic zinc powder will be high, so there is no room for addition of conductive powder and the coating strength will be insufficient. Therefore, the object of the present invention cannot be achieved.
本発明で用いられる導電性粉末としては、鉄粉、銅

が、本発明で用いる導電性材料とは粒径等の点で異なっ
たものである。When this conductive powder is used in combination with metallic zinc powder, anticorrosion, corrosion of iron and zinc, economy, when considering particle size, etc., ferroalloy-based powder is most suitable, but among them, ferrophosphorus hue, Optimal for handling.
This ferrophosphor is preferably at least one selected from Fe 3 P, Fe 2 P and FeP, and its composition is 60% by atom.
-80% Fe, 30-15% P, balance Si, Mn and inevitable impurities. It should be noted that the use of the powder of this ferrophosphole in the zinc dust coating for improving weldability, cost reduction, etc. is described in Japanese Patent Publication No. 52-15091, etc., but with a conductive material used in the present invention. Are different in terms of particle size and the like.
本発明に用いられる上記した導電性粉末の平均粒径は

塗膜から脱落しやすく防錆防食上好ましくない。The average particle size of the above-mentioned conductive powder used in the present invention is
It is 100 μm to 500 μm. Average particle size of conductive powder is 100
If it is less than μm, sufficient slip resistance cannot be obtained. Further, if the average particle size exceeds 500 μm, the size is too large, the coating workability is poor, and it is not evenly distributed in the coating film.
導電性粉末の添加量は、合成樹脂の固形分100重量部
に対して30〜430重量部、好ましくは70〜200重量部であ

性、長期の導電性が得られにくい。また、添加量が430
重量部を超えると亜粉末の含有量が少なくなるため防食
性が大きく低下する。The conductive powder is added in an amount of 30 to 430 parts by weight, preferably 70 to 200 parts by weight, based on 100 parts by weight of the solid content of the synthetic resin. If the amount of the conductive powder added is less than 30 parts by weight, it is difficult to obtain sufficient slip resistance and long-term conductivity. In addition, the addition amount is 430
If it exceeds the weight part, the content of the sub-powder becomes small and the anticorrosion property is greatly lowered.

It is also possible to further coat a coating composition of the present invention with a conductive coating material containing a large amount of stainless powder or the like to prevent accumulation of static electricity for a long period of time.
