Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An acrylic rubber-metal composite, which comprises an iron phosphate treated iron-based metal, and an adhesive layer comprising 45-75 wt. % of a phenol resin and 10-30 wt. % of titanium oxide, a divalent metal oxide, or a mixture thereof, and 0-25 wt. % of a halogenated polymer, on the basis of total solids matters, and an acrylic rubber layer, successively provided on the iron-based metal surface wherein the phenol resin in the adhesive is a mixture of 50-90 wt., % of novolak type phenol resin and 50-10 wt. % of resol type phenol resin and the iron phosphate treated iron-based metal has a surface roughness Ra (according to JIS B 0601(1994)) of up to 0.6 μm inclusively. 2. An acrylic rubber-metal composite according to claim 1 , wherein the halogenated polymer in the adhesive is a dichlorobutadiene polymer, a brominated dichlorobutadiene polymer, a chlorinated polychloroprene or a chlorinated rubber. 3. An oil seal made of an acrylic rubber-metal composite according to claim 1 .
