Studies of Low Friction Coatings for Vulcanized Elastomers

摘要

Studies have been initiated in low cost processes which produce low-friction surfaces on natural and synthetic vulcanized elastomers. Butyl rubber was chosen as the first saturated elastomer to be treated by photolytic graft polymerization of chlorinated monomer to the surface of the rubber. Ten specific treatments have demonstrated a five-fold increase in wear life on a high-speed rotary wear tester as a result of having low friction surfaces. Of the two chlorinated monomers tested as surface grafting agents, trichlorethylene appears to have less effect than perchlorethylene on the tensile properties of treated elastomers. (Author)
