Definitions

  • This invention relates to a surface preparation agent and a surface preparation method. More particularly, this invention relates to a chromium compound-free dry-in-place rust preventive surface preparation agent that can form an organic-inorganic composite coating on the aluminum sheet and aluminum alloy sheet used in the automotive sector and for household electrical appliances, construction materials, and food containers.
  • This organic-inorganic composite coating can function as an underpaint base coating or as a base coating for bonded films and improves the antirusting performance and is highly adherent for top coats and films.
  • the invention additionally relates to a rust preventive surface preparation method that uses said surface preparation agent.
  • Chromate treatments that use a treatment agent containing chromic acid, dichromic acid, or a chromate salt are known as a rust preventive surface preparation method for the aluminum and aluminum alloy (also referred to hereinafter simply as aluminum alloy) sheet that is widely used, for example, for household electrical appliances, construction materials, and food containers. Chromate treatment is carried out in order to improve the rust preventive performance of aluminum alloy surfaces and in order to improve the adherence of aluminum alloy surfaces for top coats and bonded films.
  • the chromate treatment of aluminum alloy surfaces is characterized by a high productivity and an excellent uniformity of surface treatment and has been widely practiced as a postprocessing surface treatment method.
  • Chromate treatments can be broadly divided into the following 3 categories: reactive chromate treatments, dry-in-place chromate treatments, and electrolytic chromate treatments.
  • dry-in-place chromate treatment wastes less treatment bath than the reactive and electrolytic varieties and, because it also does not require a post-treatment water rinse, it imposes a lighter load on wastewater treatment and affords a better productivity.
  • the coating produced by dry-in-place chromate treatment contains hexavalent chromium, which acts on exposed regions of the substrate metal (treatment defect regions and damaged areas that are produced post-treatment) to form a passivating coating, i.e., dry-in-place coatings have a self-repairing activity.
  • the human-toxic hexavalent chromium present in the treatment bath is eluted by contact with water, and as a result dry-in-place chromate treatment suffers from problems with regard to environmental pollution and toxic effects for the human body.
  • trivalent chromium is the main component of the coatings formed by reactive chromate and electrolytic chromate treatments.
  • the coatings formed by reactive chromate or electrolytic chromate treatment do not, however, have the self-repairing function described above and may exhibit an inadequate corrosion resistance depending on the particular service.
  • the conversion treatment bath disclosed in Japanese Laid Open (Kokai or Unexamined) Patent Application Number Sho 56-136978 (136,978/1981 ) is typical of nonchromate-type (chromium-free) surface treatment technologies.
  • This bath characteristically comprises an aqueous solution containing a vanadium compound and at least one compound selected from the group consisting of titanium salts, zirconium salts, and zinc salts.
  • This treatment bath cannot be considered a fully rationalized surface treatment for metal sheet because it is used in a treatment methodology that entails the immersion of aluminum alloy in the bath for 1 to 20 minutes and preferably 3 to 5 minutes.
  • Japanese Laid Open (Kokai or Unexamined) Patent Application Number Hei 1-246370 discloses a conversion treatment method that employs degreasing with a particular degreasing agent followed by conversion treatment with a particular conversion treatment agent.
  • the degreasing agent has a pH adjusted to 11 to 13 using alkali metal hydroxide and contains PO ion, aluminum chelating agent, and surfactant.
  • the conversion treatment agent has a pH adjusted to 1.5 to 4.0 and contains V ion, Zr ion, PO ion, and effective F ion.
  • the advantages of this method are that it does not employ chromium and that it can carry out degreasing, rinsing, and conversion treatment at high speeds while maintaining the quality level.
  • this since this is a conversion treatment method, it requires a post-treatment water rinse, there are limitations on the weight of the obtained coating, and the corrosion resistance may be unsatisfactory depending on the particular application.
  • Japanese Laid Open (Kokai or Unexamined) Patent Application Number Hei 1-131281 discloses a highly corrosion-resistant rustproof ing pigment that has both the oxidizer and deposition functions of the chromate ion.
  • a chromium-free dry-in-place rust preventive treatment is made possible through the use of 0.1 to 50 parts of this pigment per 100 parts total paint solids. This is not, however, a technology contemplated for use for surface preparation prior to painting or film lamination, and its application within this sphere has been highly problematic.
  • this invention seeks to provide a technology that can form a strongly rust preventive base coating that is highly adherent for top coats and bonded films.
  • Water is generally used as a solvent or carrier for the components of the surface preparation agent of the invention, although water-soluble or water- miscible organic solvents such as certain alcohols, ethers, glycol ethers, ketones, esters and the like could be present as co-solvents.
  • Inorganic and organic compounds containing vanadium with any available valence can be used as the water-soluble vanadium compound (A) employed by this invention.
  • Compounds that form water-soluble V-containing ions in the presence of water are particularly preferred.
  • Preferred examples of (A) are metavanadic acid and vanadic acid and salts thereof (for example, the sodium, potassium, and ammonium salts), vanadium oxides such as vanadium pentoxide, vanadium halides such as vanadium pentachloride and vanadium pentafluoride, vanadyl sulfate, vanadium sulfate, vanadium nitrate, vanadium phosphate, vanadium biphosphate, vanadium acetate, and organovanadium compounds such as vanadium acetylacetonate and vanadyl acetylacetonate.
  • the vanadium compound can be introduced into the inventive surface preparation agent by using a reducing agent in combination with a vanadium compound as described above in order to introduce the partially or completely reduced vanadium compound.
  • the reducing agent used to reduce the vanadium compound in such instances is not critical.
  • the titanium- or zirconium-containing water-soluble complex fluoride (B) used by this invention is particularly preferably a complex in which the number of bonded F atoms exceeds the valence of the titanium or zirconium.
  • This compound should also be capable of releasing protons in the presence of water or should be capable of producing hydrofluoric acid in the presence of water. Fluozirconic acid, fluotitanic acid, and salts of these compounds are typical examples of component (B).
  • the resin (C) used by this invention is particularly preferably selected from the group consisting of polyacrylic acid resins (including copolymers of acrylic acid with other monomers), polyacrylamide resins (including copolymers of acrylamide with other monomers), polyamide resins, polyurethane resins, polyester resins, phenolic resins, or epoxy resins, and should be soluble or dispersible in water (waterborne).
  • component (C) should be stable in the bath with (A) and (B) and preferably is capable of uniformly wetting the surface of the sheet, e.g., aluminum alloy, when applied thereto.
  • component (C) is preferably at least one water-soluble resin selected from polyacrylic acids, polyacrylamides, polyurethanes, polyesters, and phenolic resins.
  • the resin loses its water solubility upon evaporation of the water fraction or baking/drying.
  • the proportions of the water-soluble vanadium compound (A), titanium- containing or zirconium-containing water-soluble complex fluoride (B), and resin (C) preferably provide the following weight ratios for the vanadium (V) in the vanadium compound (A), titanium (Ti) and/or zirconium (Zr) in the complex fluoride (B), and resin (C):
  • V : (Zr + Ti) 1 : 5000 to 5000 : 1 (more preferred, 1 :100 to 100:1)
  • V + (Zr + Ti) ⁇ : (C) 10 : 1 to 1 : 100 (more preferred, 10:1 to 1 :10).
  • At ⁇ V + (Zr + Ti) ⁇ : (C) 10: (less than 1) there is a tendency for coating defects to occur when the surface preparation agent is applied and/or for the adherence of the ultimately obtained base coating for aluminum alloy surfaces to deteriorate.

  • the inventive surface preparation agent is used in particular as a rust preventive surface preparation agent for aluminum and aluminum alloys.
  • titanium-containing or zirconium-containing water- soluble complex fluoride With regard to the titanium-containing or zirconium-containing water- soluble complex fluoride, it is thought that in aqueous solution this component liberates small quantities of fluoride ion, which etches the surface of the aluminum alloy substrate and thereby secures adhesion between the substrate and the rust preventive base coating through an anchoring effect.
  • the complex fluoride upon treatment and drying, the complex fluoride is believed to precipitate metal salts on the aluminum surface, in addition to zirconium oxide or titanium oxide, and this phenomenon is thought to function as a rust preventive coating that inhibits aluminum corrosion.
  • the coating formed by the resin upon treatment and drying is thought to exercise a barrier effect against corrosive factors, such as oxygen and water, that can infiltrate from corrosive environments.
  • an organic-inorganic composite coating is formed from the inorganic solids (e.g., oxides and fluorides of Zr, Ti) and the waterborne organic polymer, and the presence of this composite coating improves the barrier performance of the coating against corrosive conditions.
  • the aluminum alloy substrate surface exposed in such regions is successively oxidized and stabilized, with the formation of nonconducting material, by the action of the water-soluble V-containing ion (e.g., vanadyl ion) produced by the vanadium compound. This again results in the manifestation of a corrosion inhibiting activity.

  • a total deposition in excess of 100 mg/m 2 accrues no additional enhancements in rust prevention and for this reason is uneconomical.
  • the adherence between the ultimately obtained base coating and the aluminum alloy surface — or the top coat or bonded film — begins to deteriorate at a total deposition in excess of 100 mg/m 2 .
  • the coating is formed by applying and drying the inventive surface preparation agent on the workpiece surface after the surface has been cleaned with a solvent-based cleaner or an alkaline or acidic water-based cleaner.
