POWER TRANSMISSION BELT COMPRISING A COATING TREATMENT OF THE FABRIC AND COATING TREATMENT THEREOF

摘要

Described herein is a belt (1) comprising a body (2) made of elastomeric material, embedded in which is a plurality of longitudinal filiform resistant inserts (3), and a working surface (4) covered with a covering fabric (5); advantageously the working surface is constituted by a toothing (4). The covering fabric (5) is treated with a coating treatment. The coating treatment comprises a fluorinated elastomer. Advantageously, the coating treatment moreover comprises an antifriction agent and an elastomer formed by at least one copolymer obtained starting from a diene monomer and a monomer containing nitrile groups, more advantageously modified with a salt of an unsaturated carboxylic acid.
