VIBRATION-DAMPING RUBBER MEMBER AND MANUFACTURING METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2013/002209

Kind Code:

A1

Abstract:

Provided are a vibration-damping rubber member which has a reduced frictional resistance between itself and a mating member and in which a coating film does not easily peel off from a rubber elastic body even at a high temperature, and a manufacturing method therefor. The vibration-damping rubber member (3R) comprises: a rubber elastic body (32R) made of a self-lubricating rubber comprising an elastomer (321R) and a bleeding lubricant (322R); a coating film (33R) which covers at least part of a sliding inner surface, which is a part of the surface of the rubber elastic body (32R) that is located on the inner side of the sliding surface, contains a resin (330R) that has a mercapto group, is deformable in accordance with deformations of the rubber elastic body (32R), and has multiple micropores (332R) formed so as to be capable of storing the bleeding lubricant (322R) that has oozed from the rubber elastic body (32R); and a lubricating film (34R) which covers at least part of the surface of the coating film (33R), is formed to contain the bleeding lubricant (322R) that has oozed from the rubber elastic body (32R) and migrated through the coating film (33R) onto the surface of the coating film (33R), and forms at least part of the sliding surface.
