Method of manufacture of composite seal metal - elastomer comprising at least one reinforcement as electrogalvanized steel sheet between two layers of elastomer.

摘要

Process in which it covers an electrogalvanized sheet (b) of a thin film polymer based on its two faces, and is shaped, the said sheet of steel, zinc-electroplated thus coated (b ') in order to serve as support for the seal to manufacture, it is of the two faces of said reinforcement by a layer of elastomer, in particular by coating a liquid elastomer not completely polymerized and a heat treatment is carried out of the baking of the elastomer. & br / electrogalvanized steel sheet coated on both its faces with a uniform film based on polymer containing more than 1% by weight of compounds phosphate (expressed in po4) and the use of this metal sheet for the manufacture of a composite seal metal -. & br / improve the corrosion resistance of the seal, in particular at the level of the reinforcement, and improvement of the environment during the manufacture of the gasket.
