いる。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an anti-corrosion coating material for metal materials, which is low cost and does not contain bituminous substances harmful to the human body, and is particularly suitable for medium-sized diameter pipes for water supply. It is suitable as an inner surface coating material 6. [Prior Art] In general, tar epoxy resin coating, polyethylene powder coating, vinyl chloride lining, etc. are used for anticorrosion coating on the inner surface of steel pipes for water service. Among these, cool epoxy resin coating has the durability of epoxy resin and excellent corrosion resistance due to the water resistance of bituminous tar, and is low cost, so it has traditionally been used mainly for medium-sized diameter steel pipes for water supply. .
しかしながら、タールエポキシ樹脂は、必須成分として
瀝青質のタールを含んでおり、そのタール中には発ガン
物質であるペンツピレン等人体に有害な物質が含まれて

んど溶出しないが、極微量は溶出していくと考えられ、
人体への影響が問題視されている。However, tar epoxy resin contains bituminous tar as an essential component, and the tar contains substances harmful to the human body, such as pentsupyrene, which is a carcinogen. Because this tar is water-repellent, it hardly dissolves into water, but it is thought that a very small amount will elute.
The effect on the human body is considered a problem.
本発明者らはこのような問題を解決すべくタール等の瀝
青質を全く含まない被覆組成物について鋭意研究を重ね
た結果、次のような事実を見出した。In order to solve these problems, the present inventors have conducted extensive research on coating compositions that do not contain any bituminous substances such as tar, and have discovered the following facts.
瀝青質の代わりにノンタール系樹脂（石油樹脂、クマロ
ンインデン樹脂、キシレン樹脂、ケトン樹脂など）を使
用したものは、瀝青質に比べると金属素地に対する透水
性が大きいため、耐水性に劣る。この透水性を改善する
には、一般に透水性の小さな樹脂の選定とともに鱗片（
フレーク）状顔料を配合する事による迷走効果が有効と
されている。しかし、石油樹脂等のノンタール系樹脂に
単に鱗片状顔料を配合しただけでは顔料と樹脂との界面
の濡れ性があまり良くない事から、界面を通じて水の浸
透が生じ易く、透水性を大幅に改善することは望めない
。Products using non-tal resins (petroleum resin, coumaron indene resin, xylene resin, ketone resin, etc.) instead of bituminous material have greater water permeability through metal substrates than bituminous material, so they are inferior in water resistance. In order to improve this water permeability, it is generally necessary to select a resin with low water permeability and scales (
It is said that the stray effect created by blending flake pigments is effective. However, simply adding a scale-like pigment to a non-tar-based resin such as petroleum resin does not provide very good wettability at the interface between the pigment and the resin, so water tends to penetrate through the interface, significantly improving water permeability. I can't hope to.
しかるに、鱗片状顔料の表面にシランカップリング処理
を施してノンタール系樹脂に配合した場合には、樹脂と
鱗片状顔料との界面接着性が著しく向上し、透水性が大
幅に改善されるのである。However, when the surface of a scaly pigment is subjected to silane coupling treatment and blended with a non-tar resin, the interfacial adhesion between the resin and the scaly pigment is significantly improved, and water permeability is greatly improved. .
こうして得られた無瀝青質のノンタール系樹脂液ｌｉｔ
組成物は、種々の実験の結果、従来のタール系樹脂被覆
材と同等もしくはそれ以上の耐久性と防食性を存してい
ることが判明した。The thus obtained non-bituminous, non-tar based resin liquid lit
As a result of various experiments, the composition was found to have durability and anticorrosion properties equal to or greater than those of conventional tar-based resin coating materials.
すなわち、本発明は、熱硬化性樹脂と石油樹脂の混合物

食被覆組成物を要旨とする。That is, in the present invention, for 100 parts by weight of the total amount of resin including the mixture of thermosetting resin and petroleum resin and its curing agent,
The gist of the present invention is an anticorrosive coating composition comprising 50 to 100 parts by weight of flaky magnesium silicate surface-treated with a silane coupling agent.
本発明において、熱硬化性樹脂にはエポキシ樹脂、フェ
ノール樹脂、ウレタン樹脂、ポリエステル樹脂等を用い
る事ができる。In the present invention, epoxy resin, phenol resin, urethane resin, polyester resin, etc. can be used as the thermosetting resin.
石油樹脂を混合するのは、耐湿性の改善のためであり、

５０重瞳部を超えた場合は、金属素地に対する密着性が
劣化して（るからである。The purpose of mixing petroleum resin is to improve moisture resistance.
40 to 1 part of petroleum resin per 100 parts by weight of thermosetting resin
It is recommended to mix in a proportion of 50 parts by weight. If the amount of petroleum resin is less than 40 parts by weight, water resistance will deteriorate and
This is because if it exceeds the 50-fold pupil area, the adhesion to the metal base deteriorates.
鱗片状顔料としてケイ酸マグネシウム（以下タルクとい
う）を選定したのは、マイカやガラスフレークに比べ安
価なこと、化学的にも安定していること等の理由による
。Magnesium silicate (hereinafter referred to as talc) was selected as the flaky pigment because it is cheaper than mica or glass flakes, and is chemically stable.
タルクの混合量を樹脂総Ｎ１００重量部に対して５０〜
１００重量部に決定したのは、５０重量部に満たない場
合は、耐水性が劣化し、１００重量部を超えると、樹脂
不足による顔料間の接触が生じて水分が透過し易くなる
からである。The mixing amount of talc is 50 to 100 parts by weight of total resin N.
The reason for deciding on 100 parts by weight is that if it is less than 50 parts by weight, water resistance will deteriorate, and if it exceeds 100 parts by weight, contact between pigments will occur due to lack of resin, making it easier for water to permeate. .
