成樹脂で被覆する方法を提供することである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a transparent synthetic resin-coated copper plate, and its main purpose is to coat the copper surface with a durable transparent synthetic resin without causing oxidative discoloration. The goal is to provide the following.

できないという問題がある。 In general, transparent synthetic resin paints that do not require baking, such as acrylic resin paints that coat the copper surface, have poor weather resistance compared to baked paints that are coated with baking paint, and the copper surface will deteriorate over a long period of time. There is a problem of discoloration, and when a baking paint is used, the copper surface becomes oxidized and discolored due to heat oxidation during baking, making it impossible to maintain the beautiful color of the copper itself.

ものであつて、後加工が容易となるものである。 The present invention has been made in view of the above points, and will be described in detail below based on Examples. In this example, the surface of a copper plate or copper-plated plate is sulfur-colored, then a scratch pattern is applied to give it an oxidized copper-like appearance, and then this is coated with a transparent synthetic resin baking paint such as alkyd, melamine, or polyester. is shown. That is, after sulfide coloring and drying the surface, a scratch pattern is applied, and then the above-mentioned transparent synthetic resin baking paint is applied, and this is introduced into a heating furnace filled with an inert gas such as nitrogen or carbon dioxide gas. The transparent synthetic resin baking paint is then baked in an inert gas atmosphere. Therefore, the copper surface does not undergo heat oxidation and discoloration during baking, and
The copper surface can be protected with a highly weather-resistant transparent synthetic resin baking paint without damaging the oxidized copper tone of the copper surface. Further, as shown in the figure, after applying a transparent synthetic resin baking paint C to the surface of the copper plate A, it is sent onto a heating plate H whose upper surface is convexly curved.
By baking while supplying an inert gas between the shielding plate S placed above and the transparent synthetic resin baking paint C, it is possible to prevent oxidation discoloration of the copper surface during baking, and also prevent bending. By using a durable transparent synthetic resin baking paint, the transparent synthetic resin baking paint C, which is stretched during baking and adheres to the copper plate A, covers the copper plate A in a compressed state after passing through the heating plate H. Even when the obtained transparent synthetic resin-coated copper plate is processed into rain gutters or roofing materials, for example, the transparent synthetic resin baking paint C does not cause cracking and post-processing is easy.
