Abstract
An acrylic rubber-metal composite, which comprises an iron phosphate treated iron-based metal, and an adhesive layer comprising a phenol resin and a metal oxide, and preferably further a halogenated polymer, and an acrylic rubber layer, successively provided on the iron-based metal surface, has not only distinguished initial adhesiveness and water resistance, when the acrylic rubber is bonded to the metal owing to application of the iron phosphate treatment to the metal surface, but also can reduce the abrasion of the mating materials when brought into contact with rubber-unbaked parts of the sheet, because the surface roughness Ra[according to JIS 0601(1994)] of the surface treated steel sheet is 0.6 or less.
