どが侵入し、発錆する原因ともなっている。However, in such a method, air bubbles remain in the spaces between the fibers of the fiber sheet, and it is difficult to completely remove them. In this state, if the weather resistant resin film is thermocompression-bonded, or the weather resistant paint is applied and cured, it will be blistered due to the expansion of the air that stays inside after mounting it as an exterior material. Occur,
Alternatively, pinholes cause moisture and water vapor to enter the voids and cause rusting.

化させることにより行われる。Therefore, the present invention relates to a method for producing a coated metal plate, wherein the coated metal sheet is produced by applying a thermoplastic sheet to the surface of a metal sheet which has been coated with an adhesive and dried, and then heat-melted the fiber into the thermoplastic sheet. It is carried out by immersing the sheet under pressure almost completely, and thereafter applying thermocompression bonding to the weather resistant resin film or applying and curing a weather resistant paint.

る。After laminating a thermoplastic sheet on a metal plate using such an adhesive, it is heated to a temperature not lower than the melting temperature of the thermoplastic resin or elastomer forming the sheet, and a fiber sheet using a heat roll or the like. Squeeze and bury it. Here, as the fiber sheet, a glass fiber sheet having a basis weight of about 10 to 20 g / m 2 , a carbon fiber sheet, a polyester fiber sheet, a polypropylene fiber sheet, a polyester non-woven sheet, a polypropylene non-woven sheet or the like is used.

布、硬化させる。In this way, the fibrous sheet is completely embedded in the thermoplastic sheet or press-fitted to such an extent that it is slightly exposed on the surface, and then a weather-resistant resin film is thermocompression-bonded thereto in the former case or the latter. In some cases, a weather resistant paint is applied and cured.

A resin-fluorine resin blend film (thickness: about 40 μ) or the like is used. As the weather resistant coating, for example, an aqueous emulsion-based or solvent-based acrylic resin coating, a solvent-based urethane resin coating, a solvent-based fluororubber coating, or the like is used.
