Example

[0087] In Comparative Example 8 in which the amount of lubricant is less than the lower limit of the specified range of the present invention, the friction coefficient becomes large (0.77), and after the bending test, obvious cracks (peeling) in the resin film can be seen, that is, the moldability is deteriorated. On the other hand, in Comparative Example 9 in which the amount of lubricant exceeds the upper limit, scratch resistance deteriorates. (The influence of the amount of colloidal silica added)

[0088] In Comparative Example 10 in which the addition amount of colloidal silica exceeded the upper limit of the specified range of the present invention, the bending workability deteriorated, and therefore, very slight cracks were seen in the resin film.

[0089] On the other hand, it was confirmed that the surface roughness (center line average roughness Ra) of the aluminum sheet, the adhesion amount of the corrosion-resistant coating, the type and thickness of the resin coating...

Abstract

An aluminum plate (1) with a film, wherein a corrosion-resistant film ( 3) and a resin film (4); the above-mentioned corrosion-resistant film (3) contains Cr or Zr, and the adhesion amount is 10 to 50 mg/m2 in terms of Cr or Zr; the average film thickness of the above-mentioned resin film (4) is 0.05 to 0.3 μm, containing 1 to 25% by mass of lubricant relative to the total amount of the resin film; the above-mentioned aluminum plate (2) or the fine protruding part of the surface on which the above-mentioned corrosion-resistant film (3) is formed is exposed on the On the surface of the above-mentioned resin film (4); on the surface on which the above-mentioned resin film (4) is formed, when a ball-shaped terminal with a radius of 10 mm is placed at the tip and pressed with a load of 0.4 N, the above-mentioned ball-shaped terminal and the above-mentioned aluminum The surface resistance value between the material plates (2) is 1Ω or less.

Description

technical field [0001] The present invention relates to an aluminum plate having a film. The aluminum plate with a film of the present invention is particularly excellent in conductivity, heat dissipation, formability, fingerprint resistance and scratch resistance, and is suitable for use as boxes and chassis of various external recording devices, and liquid crystal panels (panels). Cases on the back, frames for fixing, etc. are used as raw materials for electronic equipment frames or structural parts. In addition, the present invention also relates to electronic device components manufactured using the aluminum plate having the film. Background technique [0002] For materials used in electronic equipment, it is often required to have electrical conductivity. For example, in order to prevent erroneous operation of a magnetic disk drive unit, its housing is required to have the necessary conductivity for grounding (grounding). In addition, the liquid crystal control panel...
