  • Patent number: 11560641
    Abstract: The present disclosure provides a surface-treated aluminum material having excellent adhesiveness to resins, on the surface of which an oxide film is formed, the oxide film comprising a surface-side porous aluminum oxide film having a thickness of 20 to 500 nm and a base-side barrier aluminum oxide film having a thickness of 3 to 30 nm, wherein small pores each having a diameter of 5 to 30 nm are formed on the porous aluminum oxide film, and the length of cracks formed in a boundary between the porous aluminum oxide film and the barrier aluminum oxide film is not more than 50% of the length of the boundary, a method for manufacturing the surface-treated aluminum material, and a surface-treated aluminum material-resin bonded body, comprising the surface-treated aluminum material and a resin that covers the surface of the oxide film formed thereon.

  • Patent number: 8045321
    Abstract: A resin-coated aluminum alloy sheet material for an aluminum electrolytic capacitor case includes a resin layer that contains wax composed of at least one of polyethylene wax and carnauba wax, and has a thickness falling within a range from at least 2 ?m to at most 22 ?m. A total of lengths of wax particles, defined when the wax particles are cut along a straight line of 100 ?m optionally drawn on the surface of the resin layer, is at least 10 ?m. A number of the wax particles, featured by a cross-sectional shape having a size of at most 80% of the thickness of the resin layer and of at least 0.1 ?m, is from at least 3 to at most 50. A number of the wax particles, featured by a cross-sectional shape featured by a major axis extent having a size of more than 80% of the thickness of the resin layer is less than 10.

  • Patent number: 7722922
    Abstract: An coating apparatus, wherein the apparatus applies a coating, onto a surface of an aluminum alloy member for a heat exchanger to be assembled by brazing, with a top-feed-type roll transfer system having at least three rolls, the coating being obtained by mixing into an organic binder a metal powder, a flux powder, a powder mixture thereof, or a compound containing a metal component and a flux component, wherein rotation directions of transfer rolls of the apparatus arranged above a surface to be coated of an aluminum alloy extruded member that moves in a horizontal direction, satisfy a relationship in which a rotation direction of a coated-metal roll for coating, which rotates in a direction opposite to a moving direction of the extruded member, and a rotation direction of a metal roll for adjusting an adhesion amount of the coating by contacting with the above roll, are opposite to each other; and a method of producing an aluminum alloy heat exchanger member using the apparatus; and an aluminum alloy heat e

  • Publication number: 20090237864
    Abstract: A resin-coated aluminum alloy sheet material for an aluminum electrolytic capacitor case has a superior formability even when being formed into an aluminum electrolytic capacitor case having a large height/diameter ratio, using a volatile press oil. A resin layer contains wax composed of at least one of polyethylene wax and carnauba wax, and has a thickness falling within a range from at least 2 ?m to at most 22 ?m. A total of lengths of wax particles, defined when the wax particles are cut along a straight line of 100 ?m optionally drawn on the surface of the resin layer, is at least 10 ?m. A number of the wax particles, featured by a cross-sectional shape having a size of at most 80% of the thickness of the resin layer and of at least 0.1 ?m, is from at least 3 to at most 50. A number of the wax particles, featured by a cross-sectional shape featured by a major axis extent having a size of more than 80% of the thickness of the resin layer is less than 10.

  • Patent number: 5606152
    Abstract: Provided is a multilayer insulated wire comprising a conductor and three or more insulating layers covering the conductor, in which each of first and second insulating layers, as counted from the conductor side, is (a) an extrusion-coating layer of an intimate resin mixture compounded so that an ethylene-based copolymer, having a carboxylic acid or a metal salt of the carboxylic acid on the side chain thereof, accounts for 5 to 40 parts by weight compared to 100 parts by weight of a thermoplastic straight-chain polyester resin, (b) an extrusion-coating layer consisting mainly of a thermoplastic straight-chain polyester resin formed by combining an acid constituent and an alcoholic constituent the whole or a part of which is cyclohexanedimethanol, or (c) an extrusion-coating layer of an intimate resin mixture compounded so that the ethylene-based copolymer, having the carboxylic acid or the metal salt of the carboxylic acid on the side chain thereof, accounts for 50 parts or less by weight compared to 100 part
