Rust prevention treatment methods for metal parts and rubber compositions

Abstract

This invention relates to a method for applying rust prevention treatment to metal parts using a rubber molded body obtained from a rubber composition with rust-preventive properties. In one embodiment, this invention relates to a method for rust prevention treatment of metal parts, which involves contacting a rubber molded body obtained from a rubber composition containing one or more additives selected from the group consisting of aliphatic amines, nonionic surfactants, and maleic acid ester compounds with metal; or a rubber composition used in the aforementioned method for rust prevention treatment of metal parts, containing one or more additives selected from the group consisting of aliphatic amines, nonionic surfactants, and maleic acid ester compounds.
