Definitions

  • the present invention relates to a metal sheet material that has at least one of superior corrosion resistance, paintability, fingerprint resistance, and workability and that is used in consumer electrical and electronic products, building materials, and the like.
  • Metal sheet materials such as steel sheets, aluminum-plated steel sheets, zinc-plated steel sheets, and aluminum sheets are commonly used in a wide range of fields related to automobiles, building materials, and consumer electrical and electronic products.
  • Zinc and aluminum corrode in the atmosphere and generate corrosion products (known as white rust), which mar the appearance of the metal material and also adversely affect the paintability of the material.
  • white rust corrosion products
  • the material is susceptible to fingerprints and other soiling when handled by workers in the course of the various steps of manufacturing the finished product at the user's plant; such soiling can markedly lower the commercial value of the product.
  • oils and the like are used as lubricants in pressing and other such working of the material, and this oil has to be removed after forming.
  • the surface of a metal sheet material has been subjected to a chromate treatment using a treatment solution composed primarily of chromic acid, dichromic acid, or a salt thereof, after which the upper layer is coated with a polyolefin resin having carboxyl groups and containing colloidal silica and a wax or the like, or with a coating agent comprising a resin containing a lubricating component such as a wax (rather than imparting workability with an oil or the like), and these metal sheet materials have been used in press molding and other such applications.
  • Another well-known surface treatment method other than using a chromate involves the use of tannic acid and/or another polyvalent phenol carboxylic acid.
  • tannic acid and/or another polyvalent phenol carboxylic acid.
  • the protective film formed by a reaction between the tannic acid and the metal material becomes a barrier to the infiltration of corrosive substances, so that the corrosion resistance of the metal material is believed to be improved.
  • a surface treatment method aimed at imparting corrosion resistance to a metal material by using a water-soluble resin composed of a hydroxypyrrone derivative and a method in which corrosion resistance is imparted by using a water- soluble or water-dispersible polymer of a hydroxystyrene compound have been disclosed in Japanese Patent Publication S57-44751 , Japanese Laid-Open Patent Application H1 -177380, and elsewhere.
  • the present invention is intended to solve the above problems encountered with prior art, and it is an object of the invention to provide a chromium-free surface treated metal material with at least one, more preferably more than one, or most preferably all, of superior corrosion resistance, paintability, fingerprint resistance, and workability.
  • a coating composition according to the invention comprises, preferably consists essentially of, or more preferably consists of, the following components:
  • silane coupling agent component comprised of at least one type of silane coupling compound having one or more reactive functional moieties selected from among active hydrogen-containing amino moieties, epoxy moieties, vinyl moieties, mercapto moieties, and methacryloxy moieties;
  • Y 1 represents a hydrogen atom or a "Z" moiety that conforms to one of the following General Formulas 3 or 4:
  • each of R 3 , R 4 , R 5 , R 6 , and R 7 independently represents a hydrogen atom, a Ci to C 10 alkyl moiety, or a Ci to C10 hydroxyalkyl moiety; and X represents a hydrogen atom, a hydroxyl moiety, a Ci to C5 alkyl moiety, a Ci to C 5 hydroxyalkyl moiety, a C 6 to C 12 aryl moiety, a benzyl moiety, a benzal moiety, an unsaturated hydrocarbon moiety forming a naphthalene ring by condensation with the benzene ring to which the general formula shows X is bonded, or a moiety conforming to the following General Formula 2:
  • each of R 1 and R 2 independently represents a hydrogen atom, a hydroxyl moiety, a Ci to C 5 alkyl moiety, or Ci to C10 hydroxyalkyl moiety (if these moieties have eleven or more carbons, there will be a drop in the film formability of the resulting coating composition, so that corrosion resistance, paintability, fingerprint resistance, and/or workability may be inadequate); and
  • Y 2 represents a hydrogen atom or a "Z" moiety as described above; has an average degree of polymerization (i.e., number of units as represented by General Formula 1 per molecule of the polymer; the degree of polymerization may hereinafter be designated as "n") of 2 to 50; and - has a number of Z moieties that has a ratio to the number of benzene rings that is from 0.2 to 1.0 (if this average number of Z moiety substitutions is less than 0.2, the resulting polymer may not adhere well to the metal material and paintability may be poor; while the resulting polymer will be more hydrophilic if this number is over 1.0, the resulting metal sheet material may have insufficient corrosion resistance); and
  • the weight ratio of the silane coupling agent component (A) to the polymer component (B) preferably is from 1 :10 to 10:1 , a range of 1 : 1 to 5:1 being more preferred. If this weight ratio is less than 1 :10, that is, if the proportion of the silane coupling agent component (A) is too low, there will be a decrease in adhesion with the substrate surface, so corrosion resistance and paintability may be inadequate. On the other hand, if this ratio is over 10:1 , that is, if the proportion of the silane coupling agent component (A) is too high, there will be a decrease in the film formability of the coating composition, and the resulting metal sheet material may have inadequate corrosion resistance and paintability.
  • the silane coupling agent component (A) preferably includes at least two subcomponents:

  • the ratio of the number of equivalents of the active hydrogen-containing amino moieties in subcomponent (A.1 ). to the number of epoxy moieties contained in subcomponent (A.2) preferably is from 3:1 to 1 :3 (if the equivalent ratio of the active hydrogen-containing amino moieties to the epoxy moieties is over 3:1 , the film formability of the coating composition often will be poor, and the resulting metal sheet material may not have adequate corrosion resistance, paintability, or workability; if this ratio is less than 1 :3, though, there is not likely to be further improvement in the corrosion resistance, paintability, fingerprint resistance, or workability of the coated metal sheet material, so that such ratios are uneconomical); and, independently, the weight ratio of the combined amounts of the subcomponent (A.1 ) and subcomponent (A.2) to the amount of polymer in component (B) preferably is from 1 :5 to 5:1.
  • the weight ratio of wax component (C) to the total of silane coupling agent component (A) and polymer component (B) to be from 1 :100 to 2:1 (fingerprint resistance and workability may be inadequate if the wax component (C) is present in a ratio of less than 1 :100, and the film formability of the coating composition will be reduced if this ratio is over 2:1 , so the resulting metal sheet material may have inadequate corrosion resistance and paintability); and - the wax in component (C) to have a melting point of 40 to 120 °C (workability may be unsatisfactory in a metal sheet material obtained using a wax component having a melting point outside this range).
