Definitions

  • the invention relates to an optimized surface treatment agent that imparts both an excellent corrosion resistance and an excellent paint adherence to the surface of steel, especially steel sheet, plated with zinc or zinc-containing alloy (hereinafter abbreviated as zinciferous-plated steel).
  • zinciferous-plated steel The invention will be de ⁇ scribed below primarily with respect to use on steel sheet, but it is to be under ⁇ stood that any other shape of steel substrate may also be treated according to the invention.
  • Background Art Zinciferous-plated steel sheet utilizes the principle of sacrificial zinc corro ⁇ sion, which is a general method for preventing the corrosion of iron and steel. Zinciferous-plated steel sheet is used in a broad range of applications, extending over the automotive, building material, and household electrical appliance sect ⁇ ors.
  • One well-known non-chromate surface treatment method uses surface treatment agents based on tannic acid (tannic acid contains polyphenolic carbox ⁇ ylic acid).
  • tannic acid contains polyphenolic carbox ⁇ ylic acid.
  • zinc tannate produced by the reaction between tannic acid and zinc forms a protective coating. It is thought that the corrosion resistance of the zinciferous-plated steel sheet is improved through the action of this protective coating as a barrier to the infiltration of corrosive substances.
  • Japanese Patent Publication Number Sho 54-22781 [22,781/1979] teach- es a tannic acid-based surface treatment method comprising the treatment of zinciferous-plated steel sheet with an aqueous solution that contains at least tan ⁇ nic acid and silica sol. This method forms an ultrathin surface film that has a rust-inhibiting activity. The problem with this method is that this film still cannot deliver a satisfactory corrosion resistance. Otherwise, Japanese Patent Publication Number Sho 61 -33910 [33,910/
  • the present invention takes as its object the introduction of a chromium- free surface treatment agent that solves the problems described above for the prior art by simultaneously providing the excellent corrosion resistance and ex ⁇ cellent paint adherence required for zinciferous-plated steel sheet.
  • a coating having both a high corrosion resistance and a strong paint ad ⁇ herence can be produced by treating the surface of zinciferous-plated steel sheet with a surface treatment agent that contains a particular type of silane coupling agent and at least one selection from polyhydroxyaryl carboxylic acids and dep- sides of polyhydroxyaryl carboxylic acids.
  • the invention was achieved based on this finding.
  • the surface treatment agent according to the invention for zinciferous-plated steel sheet characteristically comprises, preferably consists essentially of, or more preferably consists of, water and the following essential components:
  • R denotes an alkyl group, which may be the same or different from one of the m YR and the n R moieties to another;
  • X denotes a meth- oxy or ethoxy moiety;
  • Y denotes a moiety selected from the group consist ⁇ ing of vinyl, amino, mercapto, glycidoxy, and methacryloxy moieties, which may be the same or different from one of the m YR moieties to an ⁇ other;
  • m is an integer with a value from 1 to 3; and
  • n is an integer with a value of 0 to (3-m); and optionally, one or more of: (C) water miscible monoalcohols;
  • (E) accelerator anions It is preferred, furthermore, that the total content of essential components (A) and (B) in the surface treatment agent according to the invention should be 1 to 50 weight %.
  • Zinciferous-plated steel which can be treated with the surface treatment agent of the invention encompasses steel coated with zinc or a zinc alloy, for ex ⁇ ample, Zn/Fe alloy, Zn/Ni alloy, Zn/AI alloy, and the like.
  • Polyhydroxyaryl carboxylic acids usable by the present invention must have at least two hydroxyl substituents and at least one carboxyl substituent on a single aromatic nucleus.
  • Such acids are exemplified by gallic acid, protocate- chuic acid, gallocarboxylic acid, and the like.
  • Suitable as the depsides of polyhy ⁇ droxyaryl carboxylic acids are, for example, meta-digallic acid, trigallic acid, diplo- schistesic acid, tannin, tannic acid, and so forth.
  • the tannin used in the present invention is a general term for substances extractable by hot water from the seeds, fruits, shells, leaves, roots, wood, and bark of plants and able to convert raw animal hides into leather.
  • Tannic acid is the tannin obtained from Chinese or Turkish nutgall, etc. The type and quantity of addition of these substances is not critical.
  • silane coupling agent that has a chemical structure with general form- ula (I) may be used in the present invention.
  • compounds from the following groups (a) - (c) can be used and are generally preferred.
  • amino-functional silane coupling agents e.g., N-(2-aminoethyl)-3-aminopropyl methyl dimethoxy silane N-(2-aminoethyl)-3-aminopropyl trimethoxy silane 3-aminopropyl triethoxy silane
  • mercapto-functional silane coupling agents e.g., 3-mercaptopropyl trimethoxy silane.
  • the surface treatment agent of the invention may in general be prepared by dissolving or dispersing the aforementioned essential components in water. While the total concentration of the essential components is not specifically re ⁇ stricted, the sum of the concentrations of the essential components, i.e., silane coupling agent + polyhydroxyaryl carboxylic acid(s) and/or depside(s) of polyhy ⁇ droxyaryl carboxylic acid(s) is preferably 1 to 50 weight %. When the total amount of these essential components falls below 1 weight %, the treated zincif- erous-plated steel sheet will not always exhibit the good corrosion resistance that is the goal of the present invention.
  • the surface treatment agent according to the invention may contain addi ⁇ tives in addition to the essential components already discussed above.
  • Metal ions may be added in order to improve the insolubility of the treated zinciferous- plated steel sheet.
  • Metal ions usable for this purpose are exemplified by iron, nickel, manganese, cobalt, zinc, aluminum, calcium, and magnesium ions, with zinc and magnesium ions being particularly preferred.
  • a reaction ac ⁇ celerator may be added in order to accelerate the reaction with the surface of the zinciferous-plated steel sheet.

  • Zinciferous-plated steel sheet treated with the surface treatment agent of the invention exhibits both an excellent corrosion resistance and an excellent paint adherence.
  • the polyhydrox ⁇ yaryl carboxylic acid or depside thereof in the treatment agent is believed to react with the zinc to form a protective coating on the surface of the zinciferous-plated steel sheet.
  • This protective coating then would prevent the infiltration of corros- ive substances, thus yielding the improved corrosion resistance.
  • the improved paint adherence is believed to occur as the result of adsorption of the functional groups in the silane coupling agent to the surface of the zinciferous-plated steel sheet.
  • a moderately alkaline degreaser (FINECLEANERTM 4336, commercially available from Nihon Parkerizing Company, Limited, Tokyo) was used a concen ⁇ tration of 20 g/L.
