The frequency of applying tar epoxy resin paints is rapidly increasing. The reason for this is largely due to the excellent seawater resistance, water resistance, chemical resistance, and adhesion of tar epoxy resin paints. There are many cases where the process progressed without the occurrence of defects such as rust.

厚不足箇所の手直し塗装などに過大な労力と時間をかけ
なければならないという塗装上の問題点があった。With conventional tar epoxy resin paints, when the dry film thickness is less than 200 μm, seawater resistance and water resistance are insufficient, and blistering and rust are likely to occur. Therefore 200μ
In order to ensure the minimum dry coating thickness of the paint, it takes excessive effort and time to manage the wet coating thickness, dry coating thickness, time for painting, etc., and to repaint areas where the coating thickness is insufficient. There was a problem with the painting that had to be done.
本発明の目的は、乾燥塗膜厚が２００μｍ未満であって

に対してはポリイソシアネートなどがある。In the present invention, the same epoxy resins, curing agents, and bituminous materials used as coating film forming components can be used as those used in conventional tar epoxy resin paints. Epoxy resins include ordinary epoxy resins such as bisphenol-type epoxy resins whose main polymerization mode is polymerization by ring-opening of epoxy rings, as well as epoxy polyol resins having a large number of hydroxyl groups in one molecule. Examples of curing agents include polyamide resins and modified polyamines for ordinary epoxy resins, and polyisocyanates and the like for epoxy polyol resins.

があげられる。Examples include combinations of polyisocyanates such as Coronate L-45EB (trade name 1, manufactured by Nippon Polyurethane Industries, Ltd.) and Epiclon B-912 (trade name, manufactured by Dainippon Ink and Chemicals, Ltd.).
エポキシ樹脂中のエポキシ基または水酸基に対する硬化
剤中のアミンまたはイソシアネート基の当量比は０．１
５〜１．３の範囲であるのが好ましい。The equivalent ratio of the amine or isocyanate group in the curing agent to the epoxy group or hydroxyl group in the epoxy resin is 0.1
It is preferably in the range of 5 to 1.3.
０．６未満では硬化速度が遅く、１．３を越えると付着
性や防食性が不十分になる。If it is less than 0.6, the curing rate will be slow, and if it exceeds 1.3, the adhesion and anticorrosion properties will be insufficient.
本発明に用いられる瀝青質としては、コールタール、コ

。The bituminous material used in the present invention includes coal tar, coal tar pitch, swollen coal, and petroleum pitch, which can be selectively used depending on the performance required for the paint.

青質が有する撥水性が低下するため防食性が不十分とな

防食性が低下する。The amount of bituminous material used is the total amount of epoxy resin and curing agent 1
The amount is 40 to 400 parts by weight, more preferably 50 to 300 parts by weight. If it is less than 40 parts by weight, the water repellency of the bituminous substance will be reduced, resulting in insufficient corrosion resistance, and if it exceeds 400 parts by weight, the curing rate will be extremely slow and the corrosion resistance will be reduced.
本発明に用いるマイカフレークは特に限定されないが、
フレーク径２０〜２００μ腸、厚さ０．１〜１０μｍの

なって付着力が低下し、外部から衝撃を受けたときに剥
離し易くなる。Although the mica flakes used in the present invention are not particularly limited,
Preferably, the flakes have a diameter of 20 to 200 μm and a thickness of 0.1 to 10 μm. Examples of such mica flakes include muscovite mica, phlogovite mica, and biotite mica. The appropriate amount of mica flakes is 5 to 30% by volume in the dry coating film. 5
If it is less than 30% by volume, the lamination effect of the mica flakes is insufficient and corrosive substances easily permeate, making it impossible to exhibit sufficient anticorrosion properties, and if it exceeds 30% by volume, the fluidity of the paint is insufficient. As a result, it becomes difficult to wet the uneven surface to be coated, reducing adhesion and making it easier to peel off when subjected to external impact.
本発明の防食塗料組成物は上記成分のほかに、他の塗膜
形成成分、顔料、防食剤その他の添加剤、および溶剤な
どを含有していてもよい。In addition to the above-mentioned components, the anticorrosive coating composition of the present invention may contain other coating film-forming components, pigments, anticorrosive agents and other additives, and solvents.
本発明の防食塗料組成物は上記各成分を混合することに
より製造される。この場合、硬化剤以外の成分を含む主
剤と硬化剤とを別々に製造して２液型の塗料とし、塗装
時に混合して使用する。The anticorrosive coating composition of the present invention is produced by mixing the above components. In this case, the main component containing components other than the curing agent and the curing agent are manufactured separately to form a two-component paint, and used by mixing them at the time of painting.
本発明の防食塗料組成物はエアレススプレー塗装その他
の方法により塗装して使用される。塗装の対象となるの
は鉄鋼構造物その他腐食の発生する部分であるが、局部
的に腐食の発生する部分がある場合にも使用可能である
。The anticorrosive coating composition of the present invention is used after being applied by airless spray coating or other methods. The paint is applied to steel structures and other areas where corrosion occurs, but it can also be used when there are areas where corrosion occurs locally.
本発明の防食塗料組成物により形成される塗膜は、従来
のタールエポキシ樹脂塗料による塗膜に比較して、乾燥
塗膜厚を大幅に低下させても満足な防食性を発揮する。The coating film formed by the anticorrosive coating composition of the present invention exhibits satisfactory corrosion resistance even when the dry coating thickness is significantly reduced compared to coating films made from conventional tar epoxy resin coatings.
これはマイカフレークによる積層効果および高アスペク
ト比（径／厚み）により、腐蝕性成分の透過速度を大幅
に遅らせるとともに、塗膜の強度や素地への付着性を向
上させるためであると推測される。It is assumed that this is because the lamination effect and high aspect ratio (diameter/thickness) of mica flakes significantly slow down the permeation rate of corrosive components and improve the strength of the coating film and its adhesion to the substrate. .
前述のように従来のタールエポキシ樹脂塗料では防食性
を維持するのに最低２００μｍの乾燥塗膜厚が必要であ
ったが、本発明による防食塗料組成物では最低乾燥塗膜
厚を１００μｍまで低下させても従来のタールエポキシ
樹脂塗料に匹敵する防食性能が得られる。As mentioned above, conventional tar epoxy resin paints require a minimum dry film thickness of 200 μm to maintain corrosion resistance, but the anticorrosive paint composition of the present invention reduces the minimum dry film thickness to 100 μm. However, corrosion resistance comparable to that of conventional tar epoxy resin paints can be obtained.
・ 以上の通り１本発明によれば、タールエポキシ樹脂
塗料にマイカフレークを配合したので、従来のタールエ
ポキシ樹脂塗料よりも薄い塗膜厚でも優れた防食性能が
得られ、塗膜厚減少による資源の大幅な削減と省力化が
可能である。- As described above, according to the present invention, mica flakes are blended into the tar epoxy resin paint, so excellent anti-corrosion performance can be obtained even with a thinner coating than conventional tar epoxy resin paints, and resources can be saved by reducing the coating thickness. It is possible to significantly reduce costs and save labor.

とした。(Test method) A blind test piece was immersed in a 3w/v% saline solution adjusted to 40°C for 6 months, and then the appearance of the coating film and its adhesion to the substrate were observed. Regarding the appearance of the paint film, the presence or absence of blistering in the paint film was observed, and if no blistering was observed, it was scored as 0 (pass), and if any blistering was observed, it was scored as × (fail). 10+sm of the painted surface with a knife
After cutting base lines at 2 mm intervals in the loam range, a peel test was performed using cellophane tape, and 25/25 was passed.
