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. The coating of these steel sheets was generally performed after processing / assembly, but in recent years, pre-coating for coating before processing / assembly has become popular. This has the advantage that the painting process can be omitted on the processing / assembly line. Since the precoated steel sheet is used for processing and assembly, it is required to have workability in addition to conventional functions such as anticorrosion. Therefore, organic polymers such as polyester resins have been used as paints.

Therefore, the present inventors have made the skeleton of an inorganic polymer composed of an OM bond (M is a metal) a -O-Si.
Inorganic substituted with (R) 2 -O- group (R is an alkyl group)
An organic fusion material was developed as a coating material for precoating (Japanese Patent Application No. 6-32003).

て必要であった。The synthesis of the above-mentioned inorganic / organic fusion product is obtained by hydrolysis of a metal alkoxide or a metal alkoxide derivative or a hydrolyzed metal alkoxide derivative and a dialkylalkoxysilane. The reactivity was low, and it was necessary to use an acid such as hydrochloric acid or acetic acid as a catalyst during the synthesis. Since the acid used for synthesis remains in the sol, the plating metal and iron are dissolved by the acid in the steps from coating to heat treatment, and remain in the film as ions. If the film is a clear film, the film becomes dark due to the remaining metal ions,
If a colored film containing a pigment is used, the color becomes uneven and spoils the beauty. Therefore, it has been necessary to develop an acid-free inorganic-organic fusion material, that is, an inorganic-organic fusion material that can be synthesized without using an acid catalyst, and to apply a steel sheet coated with it as a pre-coated steel sheet.

る。従って、酸触媒を用いずに無機・有機融合体を合成
するには、出発原料が適度な反応性を持つ必要がある。A catalyst was required because the starting material was too low in reactivity, but conversely, when the reactivity was too high, the reaction could not be controlled and a copolymer or the like was formed, so that the catalyst was fused with other components. (That is, the fusion of inorganic and organic components) is impossible. Therefore, in order to synthesize an inorganic / organic fusion product without using an acid catalyst, it is necessary that the starting materials have appropriate reactivity.

酸基ポリシロキサンを用いることにより、無機・有機融
合体の合成に適する反応性が得られることが分かった。As a reaction end, a hydroxyl group is more reactive than an alkoxy group, and as the molecular weight is increased, the stability is increased and the reactivity is lowered. Then, in order to increase the reactivity of the dialkylalkoxysilane, the terminal was substituted with an alkoxy group for a hydroxyl group, but the reactivity was too high and a copolymer such as a tetramer was formed, resulting in low reactivity. Therefore, it was found that by using a terminal hydroxyl group polysiloxane having a large molecular weight, a reactivity suitable for the synthesis of an inorganic / organic fusion material can be obtained.

It becomes possible to obtain a body-coated steel sheet, which solves the above problems.

It is characterized by being manufactured by applying a solution to a steel sheet and then heat treating it.

It is represented by b × n. It is preferable that this a is in the range of 0.5 or more and less than 1000. If it is less than 0.5, the workability is impaired, so that the coating peels off or cracks occur during processing. On the other hand, when it exceeds 1000, there is no problem in workability, but the surface hardness and heat resistance are remarkably reduced.
