Since these zinc-based plated steel sheets are insufficient in corrosion resistance and paintability as they are, they are usually subjected to a chromate treatment or a phosphate treatment. However, due to the diversification of applications of parts such as audio equipment and computers, and bottom plates of microwave ovens, etc., of zinc-plated steel plates, the required performance has become more sophisticated, and conventional chromate treatment and phosphate treatment are compatible. I can't.

60085, JP-A-58-153785,
As described in JP-A-58-177476 and the like, there is proposed a resin-coated steel sheet in which a resin film containing colloidal silica is formed on a chromate-treated film.
However, such a resin-coated steel sheet has a problem that the corrosion resistance is not sufficient because when a flaw occurs during press working or handling, corrosion progresses from the flaw portion.

It is characterized in that it is formed on the surface of the steel sheet at 0 to 2.50 g / m 2 . The water-based resin used as the film forming agent in the present invention can disperse powdery silica, which is an additive used as a corrosion resistance improver, alumina and titania, and further, if it can be applied to a steel sheet, in particular. , But is not limited to, usually polyolefin resin such as polyethylene resin, acrylic resin,

れる。The resin-coated steel sheet according to the present invention is prepared by adding powdery silica as an additive to the above water-based resin in a solid content, that is, in the range of 5 to 40% by weight after forming a coating film. A resin-coated steel sheet according to the present invention can be obtained by preparing a coating composition by applying the coating composition to a steel sheet and drying it. The resin-coated steel sheet according to the present invention is thus
It has excellent corrosion resistance because a resin coating containing powdered silica as an additive is formed on the surface. That is, it is considered that the silica particles promote formation of basic zinc chloride, which is a dense corrosion product, at the interface between the steel plate and the resin coating.

れる。Further, according to the present invention, in addition to the above silica, at least one selected from powdery alumina and titania can be used in combination as an additive. Thus, by containing at least one selected from alumina and titania in addition to silica in the resin coating, the corrosion resistance of the resin-coated steel sheet is further improved. It is considered that this is because alumina and titania suppress the permeation of water, which causes corrosion, and thus contribute to the improvement of corrosion resistance.

There is no particular improvement in corrosion resistance due to its addition, while 1
When it exceeds the weight part, the effect of silica on the corrosion resistance is weakened. In particular, in the present invention, the best effect of improving the corrosion resistance can be obtained by the combined use with silica in that the total content of alumina and / or titania is 0.2 parts with respect to 1 part by weight of silica. When it is in the range of 0.5 to 0.5 parts by weight.

When the content of the additive is less than 5% by weight in solid content, the effect of improving the corrosion resistance is not recognized, while when it exceeds 40% by weight, the resin coating has many defects and the resin-coated steel sheet. Corrosion resistance and paintability deteriorate. In particular, in the present invention, the additive content is preferably in the range of 5 to 20% by weight in terms of solid content.

きる。In the present invention, the smaller the particle size of the additive, the more effective it is in improving the corrosion resistance of the resin-coated steel sheet. However, silica, alumina, titania and the like having a particle diameter of 1 nm are very special and expensive, while when the particle diameter exceeds 40 nm, a dense resin film is not formed and the steel sheet Corrosion resistance is not improved.
Therefore, in the present invention, as the additive, those having a particle diameter in the range of 1 to 40 nm are usually preferably used, but in particular, silica having a particle diameter of 7 nm and a particle diameter of 10 to 30 nm are used. Certain alumina and titania are most preferably used. Examples of such additives include "Aerosil 1
Silica known as "00", alumina known as "aluminum oxide C", and titania known as "titanium oxide P25" (all manufactured by Nippon Aerosil Co., Ltd.) can be preferably used.

It can be obtained by forming at a ratio of g / m 2 . The paint is evenly applied to the steel plate, and the adhesion amount is 0.10 g.
It is difficult to form a resin coating of less than / m 2 , and such a resin coating has insufficient performance and cannot provide the steel sheet with the required corrosion resistance and paintability. However, when the coating amount of the resin coating exceeds 2.50 g / m 2 , although the obtained resin-coated steel sheet has excellent corrosion resistance, the production cost is high, and the resin coating during high-strength press working is high. However, the amount of peeling increases and adheres to the mold, causing various inconveniences in press working. Particularly, in the present invention, the amount of the resin coating adhered is 0.30 to
