Description of the Related Art Equipment made of metal materials is generally coated with a coating to prevent rust and improve its appearance, and the coating process includes a degreasing process as a pretreatment. In this degreasing step, alkaline degreasing, which is conventionally treated with a chlorinated organic solvent or chemicals, has been carried out, and sometimes chemical conversion treatment has been further carried out, and blasting, which is mechanical surface treatment, has been carried out. After that, hot-rolled steel plates (SPHC materials) are directly coated, but cold-rolled steel plates (SPCC materials), stainless steel materials, aluminum materials, copper and copper alloy materials are coated with adhesive strength. It is painted after applying an etching primer to improve the appearance.

If you paint SPCC materials, stainless steel materials, aluminum materials, copper, and copper alloys without applying this etching primer, the paint film will peel off. On the other hand, chlorinated organic solvents such as trichlorethylene and trichloroethane cannot be used because they are harmful to the human body, and blasting is time-consuming.

Not only that, but because it takes a long time (more than 5 hours) to dry, dirt and dust can adhere to it before it hardens, impairing its rust prevention and aesthetic appearance.

程でなる金属材の塗装方法である。[Means for Solving the Problems] One of the aspects of the present invention is a degreasing step in which fat on the surface of a metal material is removed by simple degreasing, and after this degreasing step, a short oil alkyd resin as a main component, a pigment, and an additive are removed. This is a coating method for metal materials that involves a coating process in which a paint is mixed with a desiccant and a solvent.

板（ＳＰＨＣ材）などのように、素材の表面のままでは
錆びやすい金属に対して有効である。[Action] Even if some oil remains on the painted surface, the fatty acids in the alkyd resin are compatible with the oil on the surface of the substrate, so the paint penetrates the remaining oil film and comes into contact with the substrate. However, sufficient adhesion can be obtained due to the effects of additives. In addition, since it is a short-oil alkyd and the oil and fat components are oxidized and polymerized with metal salts, drying becomes faster. The coating film formed in this manner is particularly effective on metals that easily rust on the surface of the material, such as cold-rolled steel plates (SPCC materials) and hot-rolled steel plates (SPHC materials).

に付着力を向上させていることによる。[0010] The reason why short oil alkyd resins have excellent corrosion resistance is that compared to long oil alkyd resins, the resin deteriorates less when water is present, rust preventive pigments prevent metal oxidation, and adhesion promoters are added. This is due to improved adhesion to metal materials. In addition, different types of paint can be applied as a top coat because they have excellent solvent resistance, so they do not shrink or peel, and the solid content of pigments/resins and the appropriate roughness of the surface of the paint film make it possible to apply a top coat. This is due to increasing the contact area with the painted paint and improving its physical adhesion.

First, ferrous materials such as hot-rolled steel sheets (SPHC materials) and stainless steel materials and nonferrous metal materials such as copper, copper alloys, and aluminum materials are degreased as a pretreatment. This degreasing method is a simple degreasing method in which a clean waste cloth is impregnated with lacquer thinner and 50% of the oil and fat content on the surface of the material to be coated is wiped off (note: wiping by hand is enough).

As shown in the figure, a short-oil alkyd resin coating 2 having a dry coating thickness of 30 to 40 μm is formed on a metal substrate 1 in which oil and fat remain. The components of the paint are shown in Table 1 (note: the tolerance for each value is ±5%).

By painting with a polyurethane resin paint, an epoxy resin paint, an acrylic resin paint, or an acinoalkyd resin paint, a different resin paint film 3 having strong adhesion can be formed, as shown in FIG.

を金属塩がレドックス反応で酸化重合を進める。[0018] In the above-mentioned paint, even if some oil and fat remain on the surface of the material to be coated, the fatty acids in the alkyd resin are compatible with the base surface and oil, and the silane cup agent is mixed as an additive. Because of this, it has strong adhesion. or,
The drying time after painting is short because the alkyd resin contained in the paint is a short-oil alkyd resin with a short oil length, and the oil and fat are converted into metal salts (cobalt naphthenate, calcium naphthenate, etc.).
This is because oxidative polymerization is performed using zirconium octylate, etc.). Fats and oils have double bonds, and metal salts promote oxidative polymerization of these bonds through redox reactions.
【００１９】防食性能が優れているのは、前述のように

きい。[0019] The excellent anti-corrosion performance is largely due to the excellent adhesion as mentioned above, but in addition, short-oil alkyd resins have less moisture in them than long-oil alkyd resins. Another important factor is that there is little resin deterioration in the case, and that the pigment contains a relatively large amount of anti-rust pigment (zinc phosphate).

The results of the coating film performance test of samples applied to CC material) and hot rolled steel plate (SPHC material) are as follows. First, as an initial adhesion test, a grid + sellotape test according to JIS K54001 was conducted on 100 samples each, and all samples were good without peeling. Next, as an accelerated durability test, a salt spray test according to JIS Z2371 was conducted for 500 hours, but all of the 100 samples showed signs of rust.
There was no blistering, and even in the adhesion test results of the grid+cellotape test according to JIS K54001, all the adhesives did not peel off and were good. Furthermore, different types of paints such as nitrified cotton resin paint, polyurethane resin paint,

Appropriate roughness of the pigment/resin solid content coating surface increases the contact area with the topcoat coating, making it possible to obtain a physically good adhesion surface.

。As described above, according to the method for coating metal materials and the paint for metal materials of the present invention, steel materials (SPCC materials, SPHC materials, stainless steel materials) from which oil and fat have not been completely removed can be used.
, Even after simple degreasing of aluminum materials, copper, and copper alloy metal materials, a coating film with good adhesion and high rust prevention ability can be formed even when directly applied.
It can be dried and hardened by leaving it for 30 minutes, so it can be used as an additional coating after assembling the product, and it can also be painted after the assembled product is installed at the installation site.

It can form a top coat on amino alkyd resin paints, etc., and exhibits good adhesion and high rust prevention. Furthermore, since it can be dried by leaving it at room temperature for a short time, it can be easily automated and the takt time of the painting line can be shortened, and since it is possible to form a topcoat film of different types of paint, it can also be used as an undercoat material.
