  A chain component part has a first coating film formed on an iron base material using a water-based rust preventive paint containing a water-based rust preventive pigment containing a nitrate and having good storing stability. Since zinc is eluted earlier, generation of red rust caused by iron is suppressed, and thus durability is improved. A roller chain 10 includes a zinc-iron alloy ground layer 24 formed on an iron base material 22 by impact zinc plating, a first coating film 26 formed using the water-based rust preventive paint, and a second coating film 28 formed using a water-based top coat paint containing a water-based pigment and a water-soluble or hydrolyzable silane coupling agent containing an amino group.

  一种链条部件使用水性防锈漆在铁基材料上形成第一层涂膜，该水性防锈漆含有含硝酸盐的水性防锈颜料，具有良好的储存稳定性。由于锌较早被洗脱，由铁引起的红锈的生成受到抑制，从而提高了耐久性。滚子链 10 包括通过冲击镀锌在铁基材 22 上形成的锌铁合金底层 24、使用水性防锈漆形成的第一层涂膜 26 和使用水性面漆形成的第二层涂膜 28，水性面漆含有水性颜料和含氨基的水溶性或可水解硅烷偶联剂。

  Provided are a top coat paint having good rust resistance and good adhesion, and a corrosion resistant surface-treated chain and a corrosion resistant surface-treated sprocket, on which a coating film is formed by using the top coat paint so as to prevent the occurrence of coating film powder and to exhibit good corrosion resistance. The roller chain 10 comprises inner link plates 11, a bush 12, outer link plates 13, a connecting pin 14, and a roller 15. Each of the chain components has a zinc-iron alloy ground film formed on an iron-based base material by impact zinc plating and a first coating film formed by using a water-based rust preventive paint including zinc, nitrate, and an organic compound having a mercapto group other than a mercapto group-containing silane coupling agent. Then a second coating film is formed on the first coating film by using the top coat paint comprising a pigment, sodium silicate, and an acrylic emulsion or a polyurethane water-based composition.
