ゆえ、この樹脂を金属体に被覆すると、優れた耐熱水性
及び耐薬品性を有する樹脂被覆金属体が得られると期待
される。Polyaryletherketone resin is a crystalline resin with excellent heat resistance, chemical resistance, water resistance, processability, etc. Therefore, when a metal body is coated with this resin, it is expected that a resin-coated metal body having excellent hot water resistance and chemical resistance can be obtained.
実際に、このポリアリールエーテルケトン樹脂を金属体
に被覆する際には、耐熱水性や耐薬品性の向上のために
、樹脂被覆金属体の製造工程で樹脂の結晶化を行なう必
要がある。In fact, when coating a metal body with this polyaryletherketone resin, it is necessary to crystallize the resin during the manufacturing process of the resin-coated metal body in order to improve hot water resistance and chemical resistance.

晶化が進行する場合があり、被覆層の剥離や割れの原因
となる。However, when the crystallinity of this resin is increased, residual stress due to crystallization is generated, which tends to cause peeling and cracking of the coating layer. Furthermore, even if a crystallization step is not provided in the manufacturing process of the resin-coated metal body, crystallization may proceed naturally depending on the usage conditions (for example, when used at a temperature of 100°C or higher). , causing peeling and cracking of the coating layer.

。On the other hand, polyaryl ether sulfone resin has heat resistance,
It has excellent chemical resistance and processability, is chemically stable in the temperature range from room temperature to the glass transition point, and has excellent mechanical properties such as abrasion resistance and impact resistance. Furthermore, since it is a non-grade resin, it has the advantage that when a metal body is coated with this resin, no residual stress is generated due to crystallization of the coating layer.

は比較的ブリスター（ふ（れ）や剥離が発生しに（い。JP-A-54-34335 discloses a powder coating method using such a polyaryl ether sulfone resin. In this method, the resin coating layer is treated at a predetermined temperature and then baked, thereby improving the adhesion of the resin to the metal body. Therefore, in normal use, blistering and peeling are relatively unlikely to occur.

Mixed in a weight ratio of 20. When the amount of polyaryletherketone resin increases, the coating layer tends to crack or peel due to shrinkage due to crystallization of the resin coating layer. Conversely, when the amount of the polyaryl ether sulfone resin increases, the water absorbency of the coating layer increases, resulting in a decrease in water resistance and a tendency to form blisters.

ある。From the Examples and Comparative Examples shown in Table 1 and above, it is clear that in the resin-coated metal body of the present invention, the adhesion between the coating layer and the metal body is good, and the coating layer does not peel off, cause blistering, or crack due to hot water or steam.
It can be seen that cracks are less likely to occur. When the coating layer does not contain an inorganic filler, when an aluminum powder-ethylsilicate condensate-based undercoat layer is formed, or when the undercoat layer is formed by arc spraying, slight blisters or Although some peeling occurs, the water resistance at high temperatures is satisfactory.

抗性に優れる。(Effects of the Invention) As described above, the resin-coated metal body of the present invention contains a polyaryletherketone resin and a polyarylethersulfone resin on the surface of the metal base material that has been subjected to an undercoating treatment or a thermal spraying treatment. Since the coating layer is formed of a resin composition, the properties of both resins combine to make this resin-coated metal body less prone to peeling and cracking of the coating layer and cracking of the coating film, and is resistant to heat. Excellent resistance to water, steam, and chemical solutions.
