Definitions
- the present invention relates to a novel treatment ag ⁇ ent that forms a strongly corrosion-resistant film on the surface of metals such as iron, zinc, aluminum, and the like. This film is also an excellent paint undercoat.
- SUBSTITUTESHEET tion materials In the case of automobile bodies, a zinc phosphate film is formed on the metal surface, which is then immersed in aqueous paint for electrodeposition coat ⁇ ing.
- This coating operation is a type of primer coating, and its purpose is to increase the corrosion resistance of the painted surface and to secure corrosion resistance for the interior surfaces of the automobile body, which can be difficult to finish coat.
- a primer coating is similarly applied on construction materials prior to finish coating in order to increase the corrosion resistance.
- the present invention takes as its object the introduction of a metal-surface-treatment agent that can impart a high corrosion resistance and paint adherence to metals that are suitable for phosphate film treatment, such as iron, zinc, aluminum, and the like (hereinafter briefly denoted simply as "metal") .
- metal a metal-surface-treatment agent that permits the omission of primer coating while at the same time retaining the level of corrosion resistance currently available.
- a film that exhibits the highly desirable properties specified above can be formed by treating the metal surface with a treatment agent for the formation of a film on metal surfaces, wherein said treatment agent characteristically comprises a phosphate surface treatment bath j hich contains a cationic organic polymeric compound (or salt thereof) that contains at least 1 cationic nitro ⁇ gen atom and has a molecular weight of 1,000 to 1,000,000.
- the film according to the present invention preferably is a composite film in which the resin composed of the cation ⁇ ic organic compound (or salt thereof) has penetrated into the grain boundaries between phosphate crystals with an accompanying formation of a phosphate crystal/resin com ⁇ posite.
- the surface treatment agent according to the present invention comprises the solution or stable dispersion of a cationic organic polymeric compound (or salt thereof) in a phosphate treatment bath.
- Said phosphate treatment bath comprises any surface-treatment bath that is capable of forming a phosphate film on the surface of a metal such as iron, zinc, aluminum, etc. , either for a single species of metal alone or simultaneously on the surfaces of two or more species of the preceding metals.
- its es ⁇ sential components are zinc ions and phosphate ions, but it may optionally contain nitrate ions, other metal ions (nickel, manganese, calcium, and the like), fluoride, and various types of oxidants.
- the phosphate treat ⁇ ment bath is not specifically restricted within the context of the present invention, and the present invention encom- passes all known phosphate treatment baths.
- the cationic organic polymeric compound should contain at least 1 cationic nitrogen atom and should have a molecu ⁇ lar weight of 1,000 to 1,000,000.
- organic polymers are particularly preferred that have a resin skeleton comprising at least one selection from epoxy resins, urethane resins, polybutadiene resins, acryl ⁇ ic resins, and maleic anhydride resins, wherein these resins contain a cationic nitrogen-containing group.
- the salts of the cationic organic polymeric compound encompass its inorganic salts and organic salts.
- the inor ⁇ ganic salts are exemplified by phosphate, nitrate, sulfate, and the like, and the organic salts are exemplified by ace- tate, propionate, glyconate, and the like.
- a single spe ⁇ cies or two or more species of this cationic organic poly ⁇ meric compound (or salt thereof) can be employed. Only a weak improvement in corrosion resistance is obtained at molecular weights below 1,000, while it is very difficult to obtain dissolution or stable dispersion in zinc phos ⁇ phate baths at molecular weights in excess of 1,000,000.
- paint additives such as pigment and the like
- other types of resins, activators, and the like may be added on an optional basis.
- the present invention can employ conversion treat ⁇ ment by spray or immersion as well as electrolytic metho ⁇ dologies, and the treatment agent according to the present invention is not limited to a particular treatment method. Examples
- T x salt-spray test (JIS Z 2371) : 24 hours
- T 2 wetting test (50° C, 70 % RH) : 216 hours
- Tables 2, 3, and 4 report the paint adherence and cor- rosion resistance of the films obtained by surface treat ⁇ ment, respectively, of cold-rolled steel sheet, electrogal- vanized steel sheet, and aluminum sheet. These tables also include the results for the comparison examples.
- the results confirm a remarkable im ⁇ provement in corrosion resistance and paint adherence over phosphate treatment.
- the present invention exhibits a perform- ance approximately equivalent to the application of a pri ⁇ mer coat on phosphate film.
- the metal surface treatment agent for composite film formation in accordance with the invention increases the corrosion resistance and paint ad ⁇ herence and makes possible the omission of primer coating.
