Embodiment 1

[0111] Prepared acrylic silicone resin (weight-average molecular weight: about 20,000, alkoxysilyl content: 40% by mass) 10% by mass, bisphenol A type epoxy resin 10% by mass, and propylene glycol monoethyl ether 80% by mass % of the mixture. Next, 3 parts by mass of water and 2 parts by mass of aluminum monoacetylacetonate diethylacetoacetate were added to 100 parts by mass of the mixed liquid to prepare a treatment liquid for film formation.

[0112] On the other hand, phosphorylation treatment was performed by immersing a metal material (magnesium alloy AZ91 substrate (size: 100×60×0.3 mm)) in 50 g / L of a sodium phosphate aqueous solution adjusted to 60° C. for 3 minutes.

[0113] The obtained metal material having a phosphating-treated coating was sprayed with the above-prepared coating-forming treatment solution, and heat-treated at 200° C. for 30 minutes using a drier to form a coating.

Embodiment 2

[0115] It carried out similarly to Example 1 except having performed the zirconium conversion process instead of the phosphorylation process on the metal material. The zirconium conversion treatment was carried out by immersing the metal material in 100 g / L of an aqueous ammonium zirconium nitrate solution whose temperature was adjusted to 60° C. for 1 minute.

Embodiment 3

[0117] It carried out similarly to Example 1 except having performed trivalent chromium conversion process instead of phosphoric acid conversion process with respect to a metal material. The trivalent chromium conversion treatment was carried out by immersing the metal material in 100 g / L of a trivalent chromium nitrate aqueous solution whose temperature was adjusted to 40° C. for 1 minute.

Abstract

Provided are a treatment solution and a treatment method which are capable of further improving the corrosion resistance of a metal material. According to the present invention, a chemically convertedfilm is formed on the surface of a metal material, and then a film is formed by using a treatment solution which is for film formation and contains: a silicon compound having at least one selected from the group consisting of an alkoxysilyl group, an alkoxysilylene group, and a siloxane bond; an organometallic compound; and water.

Description

technical field [0001] The present invention relates to a treatment solution for forming a coating on a metal material having a chemical conversion treatment coating, a method for forming a coating, a metal material containing a coating, and the like. Background technique [0002] As a method of imparting corrosion resistance to various metal materials such as zinc, aluminum, magnesium, cobalt, nickel, iron, copper, tin, gold, and their alloys, chemical conversion treatment by chromium, anodic oxidation treatment, top coating, etc. Surface treatment (Patent Documents 1 to 6). However, the demand for the corrosion resistance of the said metal material is increasing gradually, and there exists a problem that the required corrosion resistance cannot be satisfied by the said method.
