架橋させ、かつ、エポキシ樹脂エマルジョンをエポキシ
硬化剤の作用で硬化させる技術である。(A) One of them is to use an ethylene-vinyl acetate copolymer emulsion as a thermoplastic resin emulsion, an epoxy resin emulsion as a thermosetting resin emulsion, an iron oxide as a cross-linking agent, and an aromatic as a curing agent. A two-part or three-part coating composition using an epoxy curing agent such as an amine adduct is prepared before coating, and as the water content of the coating composition decreases after coating, an ethylene vinyl acetate copolymer is prepared. This is a technique in which the combined emulsion is crosslinked by the action of iron oxide and the epoxy resin emulsion is cured by the action of an epoxy curing agent.

報）。(B) Another one is that, in the prior art (a), the epoxy curing agent is dissolved by dissolving the epoxy curing agent with a lipophilic solvent such as a chlorine-based solvent, a fluorine-based solvent, or an aromatic solvent. A one-part coating composition was prepared to suppress the curing reaction caused by the agent, and the ethylene-vinyl acetate copolymer emulsion was changed to an iron oxide as the water content of the coating composition decreased after application. And epoxy resin emulsions are cured by the action of an epoxy curing agent as the solvent evaporates from the coating composition after application (for example, JP-A-62-270669).
ところが、前記従来技術によるときは次のような不都

化を招来し易い。On the other hand, in the case of the latter conventional technique (b), in addition to the epoxy curing agent, a solvent for dissolving it is required,
More expensive. In addition, since the curing reaction is started by the evaporation of the solvent, the solvent escapes to the surroundings. In addition, since the solvent is generally toxic or flammable, the working environment is likely to be deteriorated.
本発明の目的は、上記不都合を解消できる被覆方法
と、それに有用な被覆用組成物とを提供する点にある。An object of the present invention is to provide a coating method capable of solving the above-mentioned disadvantages and a coating composition useful for the method.

作用で硬化させる点にある。The feature of the coating method according to the present invention is that an iron oxide is used as the cross-linking agent and the curing agent, and as the water content of the coating composition decreases after application, an EVA emulsion as the thermoplastic resin emulsion is used. The cross-linking is carried out by the action of the iron oxide, and the urethane resin emulsion as the thermosetting resin emulsion is cured by the action of the iron oxide.

ましい。The coating composition preferably contains short carbon fibers, and the short carbon fibers are preferably treated in a wet state with an amphiphilic organic solvent.
本発明者は、研究、実験を重ねた結果、次の事実を知
見した。The present inventor has found the following facts as a result of repeated studies and experiments.
［１］ウスタイト（FeO）、マグネタイト（Fe3O4）、ヘ

ジョンを硬化反応させる。即ち、ウレタン樹脂エマルジ
ョン等が有する水酸基（−OH）どうしの間に鉄イオン
（Fe2+）がイオン結合して強固な重合体を形成すると考
えられる。[1] Iron oxides such as wustite (FeO), magnetite (Fe 3 O 4 ), and hematite (Fe 2 O 3 ) disperse in thermosetting resin emulsions such as urethane resin emulsions and epoxy resin emulsions. The thermosetting resin emulsion is cured. That is, it is considered that iron ions (Fe 2+ ) are ion-bonded between hydroxyl groups (—OH) of the urethane resin emulsion or the like to form a strong polymer.
［２］しかも、熱硬化性樹脂エマルジョンの鉄酸化物に
よる硬化反応は、熱硬化性樹脂エマルジョンの含水量が
多いと起らず、熱硬化性樹脂エマルジョンの含水量か少
なくなったときから開始する。このため、未使用の段階
では被覆組成物を密封状態に保持しておき、使用に際し
て開封すれば自然に水分が蒸発して効果を開始させるこ
とができる。よって、従来のごとく、使用に際して別途
硬化剤を混入するという手間を省略することができる。[2] Moreover, the curing reaction of the thermosetting resin emulsion with the iron oxide does not occur when the water content of the thermosetting resin emulsion is high, and starts when the water content of the thermosetting resin emulsion becomes low. . For this reason, when the coating composition is kept in a sealed state at an unused stage, and when opened at the time of use, moisture evaporates naturally and the effect can be started. Therefore, it is possible to omit the trouble of separately mixing a curing agent when using it as in the related art.
［３］又、ウレタン樹脂エマルジョンの含水量が少なく
なって一旦、硬化反応が開始されると、水中であっても
その硬化反応は継続されるから、硬化開始後の天候の変
化等に影響されることもない。[3] Also, once the water content of the urethane resin emulsion is reduced and the curing reaction is started, the curing reaction is continued even in water, so it is affected by changes in weather after the start of curing. Never even.
そして、炭素短繊維を加えたときは、それによる補強
作用に上り引っ張り強さ、引き裂き強さが向上する。When short carbon fibers are added, the reinforcing action of the short carbon fibers increases the upward tensile strength and tear strength.

り、含水量の低下が保証される。In particular, when the short carbon fiber is used in a wet state, such as by dipping in an amphiphilic organic solvent such as ethylene glycol or propylene glycol, the fluidity and leveling property of the coating composition are improved, and the coating is performed. The pores that reach the surface are formed by evaporation of the amphiphilic organic solvent along the short carbon fibers later, regardless of the formation of a film in which the surface hardens first, the evaporation of water from the coating composition, that is, In addition, a reduction in the water content is guaranteed.
