活用品まで使用されている。2. Description of the Related Art Steel sheets are generally painted and used. The purpose of painting is largely to protect the base steel sheet while at the same time increasing durability and beautifying it. Painted steel sheets are used for large items such as buildings, ships and bridges, as well as various machinery and automobiles, furniture, small electrical appliances and daily necessities.

用されている。The coating of these steel sheets is generally called post-coating and is performed after processing and assembly. However,
In recent years, particularly in the field of home appliances, etc., there is a shift to a method of directly processing and assembling prepainted steel sheets that have already been painted. Pre-coated steel sheets are required to have workability in addition to conventional functions such as anticorrosion. In order to satisfy the above function, an organic polymer such as polyester resin is used as a paint.

方法を提供することを目的とする。Since the coating process of the precoated steel sheet can be omitted from the processing / assembly line, precoating can be applied to the fields such as high hardness, high weather resistance and high heat resistance, which are currently dependent on postcoating. It has come to be requested. However, since the conventional precoated steel sheet is basically coated with an organic polymer, there is a limit in surface hardness, weather resistance, heat resistance and the like. On the other hand, a method of coating glass or ceramics to improve the surface hardness and heat resistance of the steel sheet can be considered, but the workability is impaired and it cannot be used as a precoated steel sheet. For example, enamel cannot be processed, and if it is processed by bending or the like, the coated glass will be easily peeled off. Therefore, an object of the present invention is to provide a weather-resistant and heat-resistant steel sheet which is excellent in workability and has a coating of high hardness and a method for producing the steel sheet, in order to solve the above problems.
