Definitions

  • the present invention relates to a stainless steel plate having pest repellent properties and a method for producing the same.
  • the stainless steel sheet can have a high-grade appearance utilizing the beautiful metallic luster unique to stainless steel (see, for example, Patent Documents 1 and 2). For this reason, it is widely used for housings, interior materials, and cover materials of electrical appliances regardless of household or business use. Stainless steel sheets are widely used not only for their high-grade appearance but also for their corrosion resistance, so they are widely used in household or commercial kitchens and appliances installed in kitchens. Incidentally, pests such as cockroaches tend to come close to places around the water such as kitchens and kitchens, and therefore pest control is required. In particular, many household appliances such as refrigerators and rice cookers generate heat due to their mechanism. Since household appliances that have generated heat tend to be a hotbed for insects such as cockroaches, materials used for household appliances are required to have insect repellent properties.
  • the contact repellent-type pest repellent concentrates and is unevenly distributed on the surface layer portion of the coating film, thereby exhibiting a repellent effect when directly in contact with pests. Since the contact repellent pest repellent itself does not change in quality, a long-term sustained effect can be expected. However, when the contact repellent pest repellent is not unevenly distributed in the surface layer portion of the coating film, the effect becomes low. Volatilization-repellent pest repellents gradually volatilize themselves, so that they do not attract pests, and have the advantage of widening the range for repelling pests.
