Problems solved by technology

However, the chemical conversion film formed by this chemical conversion treatment is usually light-colored or colorless and transparent, so it is difficult to confirm whether the chemical conversion treatment (film formation) has been performed.
In this regard, there is room for improvement in production management

Embodiment 1

[0045] [Aluminum Metal Products]

[0046] A flat plate [25.4 mm×60 mm×3 mm (thickness)] made of aluminum alloy A6063 was prepared.

[0047] [Treatment agent for chemical film formation]

[0048] Mix 5.0 g of 2% by weight potassium permanganate aqueous solution and 5.0 g of 1% by weight zirconium fluoride hydrogen fluoride aqueous solution (by weight, zirconium fluoride: hydrogen fluoride = 1:1), and dilute the obtained mixed solution so that the Potassium manganate is 0.1 g / liter, and zirconium hydrofluoric acid·hydrogen fluoride is 0.05 g / liter. Its pH is 3.2. In this way, a treatment agent for chemical film formation was prepared.

[0049] [Formation of chemical film]

[0050] First, the entire surface of the above-mentioned aluminum-based metal product (flat plate) was immersed in an alkaline degreasing solution heated to 60° C. for degreasing. Then, the whole surface after this degreasing was blasted and roughened (the ten-point average roughness (Rz) was 20 μm). Nex...

Embodiment 2

[0053] [Treatment agent for chemical film formation]

[0054] Mix 5.0 g of 2% by weight potassium permanganate aqueous solution and 10.0 g of 1% by weight zirconium fluoride hydrogen fluoride aqueous solution (by weight, zirconium fluoride: hydrogen fluoride = 1: 1), and dilute the obtained mixed solution so that the Potassium manganate is 0.1 g / liter, and zirconium hydrofluoric acid·hydrogen fluoride is 0.1 g / liter. Its pH is 2.7. In this way, a treatment agent for chemical film formation was prepared.

[0055] [Formation of chemical film]

[0056] In the above-mentioned Example 1, the immersion into the treatment agent for forming the chemical conversion film was set at 40° C. for 3 minutes to form the chemical conversion film. Other than that, it is the same as the above-mentioned Example 1.

[0057] The manganese content derived from the manganese oxide in the formed above-mentioned chemical conversion film is 12.5 mg / m in terms of manganese atomic weight 2 , the cont...

Embodiment 3

[0059] [Treatment agent for chemical film formation]

[0060] Mix 5.0 g of 2% by weight potassium permanganate aqueous solution and 10.0 g of 1% by weight zirconium fluoride hydrogen fluoride aqueous solution (by weight, zirconium fluoride: hydrogen fluoride = 1: 1), and dilute the obtained mixed solution so that the Potassium manganate is 0.1 g / liter, and zirconium hydrofluoric acid·hydrogen fluoride is 0.1 g / liter. Furthermore, pH was adjusted to 4.0 by adding 28% ammonia water. In this way, a treatment agent for chemical film formation was prepared.

[0061] [Formation of chemical film]

[0062] In the above-mentioned Example 1, the immersion into the treatment agent for forming the chemical conversion film was set at 40° C. for 1.5 minutes to form the chemical conversion film. Other than that, it is the same as the above-mentioned Example 1.

[0063] The manganese content derived from the manganese oxide in the formed above-mentioned chemical conversion film is 12.2 mg...

Abstract

A rubber member is provided which includes an aluminum-based inner metal tube (2) (aluminum-based metal component), a film (A) chemically formed on an outer peripheral surface of the inner metal tube (2), an adhesive layer (C) provided on an outer surface of the film (A), and a vibration damping rubber (1) provided on an outer surface of the adhesive layer (C). The film (A) contains manganese oxide and zirconium oxide. In the film (A), manganese from the manganese oxide is present in a content of 10 to 30 mg / m 2 on a manganese atom weight basis, and zirconium from the zirconium oxide is present in a content of 5 to 40 mg / m 2 on a zirconium atom weight basis. The film (A) is free from deterioration in, adhesion to the aluminum-base metal component which may otherwise occur due to heat applied for vulcanization of a rubber material, and is excellent in followability to deformation of the aluminum-based metal component. Further, it is easy to visually check the presence of the film (A) on the surface of the aluminum-based metal component.

Description

technical field [0001] The present invention relates to a method for manufacturing a rubber member with an aluminum-based metal product such as a bushing for an automobile, an engine mount, and an anti-vibration member for an industrial machine, and the rubber member with an aluminum-based metal product obtained therefrom. Background technique [0002] In recent years, bushings for automobiles, engine mounts, anti-vibration members for industrial machinery, etc., are rubber members with aluminum-based metal products that are formed by integrating aluminum-based metal products and rubber members, and are used as various components such as frames and engines. It is used as a connecting member between products. [0003] In rubber members with aluminum-based metal products such as the above-mentioned anti-vibration members, at the interface between the aluminum-based metal product and the rubber, when the surface of the aluminum-based metal product corrodes, the rubber material ...
