- Japanese Patent Application Laid-Open No. 8-290520 discloses that one or more water-soluble and / or water-dispersible acrylic resins having a glass transition point of 10 ° C to 85 ° C, and 0.2% based on the solid content of the resin.
- a lubricated metal material having a film is disclosed.
- the acrylic resin is A water-soluble copolymer of len, a methacrylic acid ester and a monomer having a carboxyl group, wherein the methacrylic acid ester has a glass transition point of at least o ° c, and is an aliphatic having at least 2 carbon atoms with the methacrylic acid ester.
- a coating film-type paint made of a monohydric alcohol and a force, and a lubricated metal material.
- the glass transition point of the water-soluble copolymer disclosed in the alkali film-coating type paint is at most 92 ° C.
- JP-A-3-203996 discloses an esterified product obtained by at least partially esterifying a copolymer containing maleic anhydride and styrene as main monomers with one or more hydroxyl group-containing conjugates.
- thermosetting acryl-based resin whose glass transition point is adjusted to -10 to 25 ° C, 3 to 15 parts by weight of a resin, and 0.5 to 5 parts by weight of a surfactant
- the part and the rest are water-based liquids, wherein the weight ratio of the thermosetting acrylic resin / wax is adjusted to 2 to 12, by a metal cold working lubricant.
- EP 1 038 933 A1 styrene or substituted styrene, a methacrylic acid ester obtained from an alcohol having 2 or more carbon atoms and methacrylic acid, and an olefin compound containing at least one carboxyl group are respectively described as follows: (0.05 to 44.5):
- the press moldability is improved by a paint plastic containing a methacrylic resin copolymerized at a molar ratio of (0.12 to 13) and a lubricated metal plate coated with this. Suggestions have been made to improve it.
- none of the surface-treated metal plates described in JP-A-8-290520, JP-A-2000-38539, JP-A-8-291294 and JP-B-63-8489 have a sufficient glass transition point.
- the mold temperature is between 100 ° C and 200 ° C
- the driving force of a machine with a thickness reduction rate exceeding 50% When applied to transmission parts, mold galling and abrasion of the film occur, and press formability cannot be said to be sufficient. This is because, when severe ironing is performed, the mold temperature rises due to the resulting heat and the surface treatment film becomes soft, and the metal, which is the material, easily comes into contact with the mold. .
- EP 1 038 933 A1 also causes the glass transition point of the copolymer to not exceed 100 ° C, which in turn causes mold galling on the metal plate, significant reversal, and reduced sliding characteristics. .
- Japanese Patent Application Laid-Open No. 3-203996 discloses that, although the styrene-maleic acid copolymer itself has a high glass transition point, an esterified product or a salt thereof at least partially esterified by one or more hydroxyl group-containing compounds is an essential component. As a result, the glass transition point of the entire film is lowered, and there is a problem in lubricity during severe ironing because it does not contain a lubricant.
- the drive-transmitting components of a machine usually go through several stages of cylindrical forming, and finally have the most demanding toothing process. If the surface treatment film is worn or peeled off by the time of this toothing process, breakage and mold seizure will occur, so securing the wear resistance of the film is an important issue.
- press oil is applied to a mold and Z or a metal plate in order to mitigate an increase in mold temperature.
- the cooling effect of the press oil decreases with the increase in the number of times of press forming, which may cause breakage and mold seizure.
- mackerel may be generated even when a P-polishing agent is added. There was still room for improvement.
- the present invention is directed to an invention of a surface-treated metal sheet having excellent press moldability, especially excellent mold resistance, lubricity, and excellent heat resistance even under severe ironing.

- the metal stearate is Zn stearate.
- the thermoplastic resin preferably has a weight average molecular weight of 10,000 to 100,000 and is a water-soluble polymer.
- the anti-galling agent is at least one selected from the group consisting of a phosphoric acid, a zinc salt of molybdate molybdate and a molybdate, a magnesium salt, a calcium salt and an ammonium salt. It is preferred that
- any coating of the above is also 0.5 mass inhibitor galling the type 0 /.
- any of the above-mentioned paints further contain 0.5 to 10% by mass of an organic lubricant.
- any of the above-mentioned paints further contains a drying accelerator.
- the present invention is a paint containing a thermoplastic resin having a glass transition point of more than 100 ° C. and an acid value of 20 to 350 mg-KOH / g, metal stearate, and an anti-galling agent. It is also an invention of a surface-treated metal plate having the coating film.
- the thermoplastic resin constituting the paint of the present invention is made of glass so that the surface-treated metal sheet of the present invention can secure mold resistance and lubricity even under severe ironing and the accompanying high temperature environment.
- the transition point (also denoted as Tg) must be over 100 ° C. If the glass transition point of the thermoplastic resin is 100 ° C or less, the soft component will be separated from the metal plate or melted by the heat generated during sliding during processing.
- the preferred glass transition point of the thermoplastic resin is above 100 ° C to 250 ° C, more preferably above 100 ° C to 200 ° C.
- "severe ironing and the accompanying high temperature environment” means that the thickness reduction rate is about 50%, the mold temperature is 100 ° C or higher, and 200 ° C when continuous processing is performed. -It's a good environment.
- the acid value of the thermoplastic resin is 20 to 350 mg-KOH / g.
- the acid value is in this range, it is advantageous for the resin itself to be made water-soluble, and the metal surface-treated metal plate can also have a sufficient ability to remove the film. If the acid value is less than 20 mg-KOH / g, the adhesion of the coating to the film is reduced, and the press formability of the surface-treated metal plate is reduced. On the other hand, when the acid value is higher than 350 mg-KOH / g, the protection of the surface-treated metal sheet is extremely reduced.
- the acid value refers to the number of mg of potassium hydroxide required to neutralize lipoxyl groups contained in 1 g of the thermoplastic resin. In the present application, it is expressed in mg-KOH / g.
- the paint of the present invention may be aqueous or non-aqueous, but is preferably used in an aqueous form. Therefore, as the thermoplastic resin described above, a water-soluble resin is preferable. Resins can be broadly classified into water-soluble resins and water-dispersible resins. To obtain a water-soluble resin, the resin molecule Water solubility can be imparted by introducing a predetermined functional group such as a carboxyl group into the chain. Considering the film formation process when each resin is used, the water-soluble resin can be formed by entanglement of the resins by evaporating water as a solvent. Also, even if a small amount of water remains in the film, the mechanical properties unique to the resin are hardly impaired.
- water-dispersible resins are usually dispersed in water with a surfactant or the like in the form of particles, so fusion of the resin particles is essential for film formation, and heating above the glass transition point of the resin is required. It is.
- the water-dispersible resin itself generally has a very high molecular weight, but requires a surfactant, and in some cases, the film strength may be reduced. From the above, in order to form a film under low-temperature drying conditions of about 50 to 100 ° C and to bring out the properties of a resin with a high glass transition point, a water-soluble resin that can be formed only by solvent evaporation must be used. It is preferable to select.
- water-soluble resin it is preferable to use an acryl resin.

- Monomers of methacrylic acid esters include methacrylic acid such as methyl methacrylate, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, and iso-butyl methacrylate. And aliphatic monovalent alcohol. Since these methacrylates have a higher glass transition point than, for example, acrylates, the coating has excellent abrasion resistance during press molding. The reason why the ester is used is that when an organic acid such as atalylic acid or methacrylic acid is used as a monomer, the protective property is extremely lowered. This is because the amount of carboxyl groups in the resin is too large, and the interaction with water is too strong due to an increase in the acid value.
- the aliphatic monohydric alcohol preferably has 2 or more carbon atoms.
- Styrene has a high moisture resistance and a high glass transition point, so that the obtained surface-treated metal sheet exhibits an effect of achieving both the press moldability and the heat resistance.
- the monomer having a carboxyl group acrylic acid, methacrylic acid, maleic acid, ditaconic acid and the like are preferable.
- This carboxyl group imparts a suitable water solubility to the paint forming the lubricating film.

Further, the mixture is heated and stirred at the same temperature for 2 to 8 hours to complete the polymerization. Then, after cooling to 55 to 60 ° C., the mixture is neutralized with an alcohol such as ammonia or amine to make it water-soluble, thereby obtaining a predetermined water-soluble resin.
- an alcohol such as ammonia or amine
- adjustment of the glass transition point and acid value of the thermoplastic It can be realized by adjusting the polymerization ratio of the polymer.
- methacrylic acid ester has a higher glass transition point as the alkyl side chain of the monomer having a carboxyl group is shorter-the glass transition point of the copolymer can be increased by increasing the degree of polymerization of these monomers. it can.
