Patent number: 6656582Abstract: A rubber product with a metallic structure formed from an aluminum material having a vulcanized rubber bonded thereto. The vulcanized rubber is formed from a composition in which a natural rubber and an acrylic rubber are mixed in a proportion of 90/10-60/40 by weight. The vulcanized rubber has an island-sea structure in which fine particles of said acrylic rubber having a size of 0.1-100 &mgr;m are dispersed in a matrix phase of the natural rubber. A method of producing the rubber product with the metallic structure is also disclosed.Type: GrantFiled: May 31, 2001Date of Patent: December 2, 2003Assignee: Tokai Rubber Industries, Ltd.Inventors: Takehiko Taguchi, Ako Yoshikawa, Shinji Iio

Publication number: 20030203220Abstract: A gasket material includes a steel plate, and a cured film made of a mixture of an unvulcanized rubber compound and a phenol-modified xylene resin and directly formed on one or each of opposite surfaces of the steel plate. Preferably, the unvulcanized rubber compound is constituted by a mixture of metallic oxide and NBR polymerized with a surface active agent. Further preferably, the cured film is made of a mixture of 88% by weight to 95% by weight of said unvulcanized rubber compound and 5% by weight to 12% by weight of said phenol-modified xylene resin.Type: ApplicationFiled: March 31, 2003Publication date: October 30, 2003Inventors: Hiroshi Saito, Kenichiro Ishikawa

Publication number: 20030188818Abstract: This invention relates to an unvulcanized rubber tire which has at least one wire reinforced rubber component which contains wire reinforcement encapsulated with an unvulcanized rubber composition comprised of natural cis 1,4-polyisoprene rubber, and liquid polyisoprene polymer. The said encapsulation rubber composition of the tire component is then sulfur cured together with the curing of the tire itself. Such tire component may be, for example, a carcass ply and/or belt ply.Type: ApplicationFiled: April 9, 2002Publication date: October 9, 2003Inventors: Charles Edward Drvol, Shahir Rafael Azer, Marc Jules Alexis Henoumont, Michael Brendan Rodgers

Patent number: 6589666Abstract: Load-bearing structure comprising at least two layers (10, 20, 155, 160, 300, 310) joined by a bond line having a thickness of t mm, a shear strength of T N/mm2, and comprising a sheet (30, 130, 320) made of an elastic material having a shear modulus of G N/mm2, whereby tT2/G is at least 5 N/mm. A method for producing such a load-bearing structure in which a sheet (30, 130, 320) of rubber is treated with an oxidant, excess oxidant is removed, whereafter the sheet is glued between the two layers (10, 20, 155, 160, 300, 310).Type: GrantFiled: September 26, 2001Date of Patent: July 8, 2003Assignee: Akzo Nobel N.V.Inventors: Peter Herder, Per Johan Gustafsson

Patent number: 6524698Abstract: A fluid impermeable foil for use in connection with the wrapping of foodstuffs, cosmetics and other products has a plastic substrate one side of which is coated with a film of metallic material, such as aluminum. The exposed surface of the metallic film is provided with a thin protective layer which contains a wax, a resin, a lubricant and/or another organic material and shields the metallic film from scuffing, corrosion and direct exposure to air and/or moisture. The metallic material of the film is vaporized onto the one side of the substrate, and the organic material of the protective layer is vaporized onto the exposed surface of the film in one or more stages as soon as the vaporization of metallic material upon the substrate is completed.Type: GrantFiled: March 25, 1998Date of Patent: February 25, 2003Inventor: Helmuth Schmoock

Publication number: 20030022005Abstract: There is provided a non-chromium treated material in which peeling resistance between a metal plate and a rubber layer via a primer layer and a bond layer, which is decreased by fretting and antifreeze liquid, can be improved, the rubber layer is less liable to peel from the metal plate, and the material has little effect on the environment and human body. In a metal gasket raw material plate 1 of a laminated form in which a rubber layer 5 is provided on a stainless steel plate 2 via a bonding layer 4, a primer layer 3 of a silica-alumina condensate is formed on the surface of the stainless steel plate 2.Type: ApplicationFiled: February 19, 2002Publication date: January 30, 2003Inventors: Masabumi Miyashita, Shingo Watanabe, Norifumi Misumi, Naomichi Mitsuyama

Patent number: 6503601Abstract: A deformable roof flashing material for use in connection with skylight windows and roof penetrating structures is provided. The roof flashing material includes a sandwich construction with two outer layers of metal foil and at least one intermediate layer positioned between the outer layers. The material has, in at least one direction, a continuous wave form. At least the intermediate layers adjacent to the outside layers are made from a non-adhesive resilient material. The wave form is formed in such a manner that it maintains the mutual positioning between the outer layers and the adjacent intermediate layers by friction.Type: GrantFiled: May 30, 2000Date of Patent: January 7, 2003Assignee: VKR Holding A/SInventor: Allan Edvardsen
