この発明は、建築内外装材、家電製品、器物、自動車内

レコート鋼板に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a prepainted steel sheet that can be suitably used for interior and exterior materials of buildings, home appliances, utensils, automobile interior materials, etc. The present invention relates to a matte pre-coated steel sheet having a soft feel.
近年、建築内外装材、家電製品、器物、自動車内装材等
の製品を製造する業界において、より高級感のある艶消
し性プレコート鋼板についての要望が強くなっている。In recent years, in industries that manufacture products such as interior and exterior materials for buildings, home appliances, utensils, and interior materials for automobiles, there has been a strong demand for more luxurious matte precoated steel sheets.
このような要望に対して、いくつかの艶消し性プレコー

、外観が単に艶消し状になっているにすぎない。質感に
おいては、通常の塗装鋼板と同様であり、鋼板の持つひ
やり感があり、装飾性の点で充分ではない。In response to such demands, several matte precoated steel sheets have been developed. Examples of such steel plates include coatings containing inorganic powder such as silica and alumina with a particle size of 5 to 20 μm applied to the steel plate, or coatings containing thermoplastic resin powder such as nylon and polypropylene with a particle size of 5 to 20 μm. There is a method that applies this to steel plates. Among these, pre-coated steel sheets coated with paint containing inorganic powder have a merely matte appearance. In terms of texture, it is similar to ordinary painted steel sheets, and has the cool feeling that steel sheets have, and is not sufficient in terms of decorativeness.

艶消し性の点で不充分である。On the other hand, pre-coated steel sheets coated with paints containing thermoplastic resin powder have a semi-matte appearance with a matte texture and are slightly superior to pre-coated steel sheets coated with paints containing inorganic powders. Show your feelings. However, this pre-coated steel sheet also has a cool feeling peculiar to steel sheets, and is insufficient in terms of matte properties.

と、クロス調のソフトな感触を与える。By the way, a paint containing colored elastic polymer beads (crosslinked colored spherical resin powder) and an elastic resin binder is known as a decorative paint for concrete walls or plastic substrates. This paint gives the substrate a multicolored matte appearance and a cloth-like soft feel.
そこで、本発明者らは、上記着色弾性ポリマービーズと

プレコート銅板を得ることは困難であることが見出され
た。Therefore, the present inventors thought that an excellent high-grade precoated steel sheet with high decorativeness could be obtained by applying a paint containing the colored elastic polymer beads and an elastic resin binder to a steel sheet. However, even if this paint is applied directly to a steel plate, it is difficult to obtain a pre-coated copper plate that has a satisfactory matte appearance, reduces the cool feeling characteristic of iron, and has a soft cross-like feel. Something was discovered.
したがって、この発明の目的は、艶消し外観およびクロ

装飾性が充分なプレコート鋼板を提供することにある。Therefore, an object of the present invention is to provide a precoated steel sheet that has a matte appearance and a cross-like feel, and has sufficient decorative properties without exhibiting the cool feeling peculiar to steel sheets.

It has also been found that it is optimal to use a coating composition in which the total amount of the colored spherical resin powder and the inorganic powder is 80% by volume or less of the solid content of the coating film.

した不均質な塗膜となり装飾性が悪くなる傾向にある。In the precoated steel sheet of the present invention, the coating composition forming the coating film on the uppermost layer contains a crosslinked colored spherical resin powder and an inorganic powder. Among these, the average particle diameter of the crosslinked colored spherical resin powder is 20 to 150μ,
The blending ratio thereof is 30% by volume or more of the solid content of the coating film. If the average particle size is less than 20 trm, it is difficult to obtain a coating film with a soft cross-like feel;
If it exceeds 0 m, the coating film will be rough and non-uniform, and its decorative properties will tend to deteriorate. If the blending ratio is less than 30% by volume, it becomes difficult to obtain a coating film with a matte appearance, which tends to become glossy and lose its cloth-like soft feel. On the other hand, the average particle diameter of the inorganic powder is 5 to 150 μs, and its blending ratio is 5% by volume or more of the solid content of the coating film. If the average particle size is less than 5μ, it will be difficult to improve the matting properties, scratch resistance, texture, etc. by adjusting the surface roughness of the coating, and if it exceeds 150x, it will be rough and uneven. This tends to result in a rough coating and poor decorative properties.

にある。On the other hand, if the blending ratio is less than 5% by volume, it will be difficult to obtain a coating film with a super matte appearance and also difficult to obtain a coating film with excellent scratch resistance. Further, the total amount of the colored spherical resin powder and the inorganic powder is 80% by volume or less of the solid coating film. The blending ratio of these is 8
If it exceeds 0% by volume, the coating film becomes brittle and porous, and the coating film tends to crack or peel during bending of the pre-coated steel sheet, and its corrosion resistance tends to deteriorate.
