Abstract
Official abstract text for this publication.
A power transmission belt having a belt body, a tensile cord embedded in the belt body, and a jacket defining a pulley contact surface, where the jacket has been treated on at least the pulley contact surface with an aqueous fabric treatment or dip which includes an aqueous PEEK dispersion as part of the dip. The aqueous dip may further include an epoxy and a rubber latex. The aqueous dip may further include graphene or graphene oxide. The fabric may include aramid or nylon fibers. The jacket may cover the teeth of a toothed belt.
First claim
Opening claim text (preview).
What is claimed is: 1 . A power transmission belt comprising a belt body, a tensile cord embedded in the belt body, and a jacket defining a pulley contact surface; the jacket having been treated on at least the pulley contact surface with an aqueous dip comprising a dispersion of polyetheretherketone (“PEEK”) and dried. 2 . The power transmission belt of claim 1 , wherein the aqueous dip further comprises epoxy and a latex. 3 . The power transmission belt of claim 2 , wherein the aqueous dip further comprises graphene or graphene oxide. 4 . The power transmission belt of claim 1 , wherein the concentration of the PEEK in the aqueous dip is in the range of 1% to 5% on a wet weight basis. 5 . The power transmission belt of claim 1 , wherein the jacket comprises a fabric comprising aramid fibers. 6 . The power transmission belt of claim 1 , wherein the jacket comprises a fabric comprising nylon fibers. 7 . The power transmission belt of claim 1 in the form of a synchronous belt and further comprising teeth defining the pulley contact surface. 8 . A power transmission belt comprising a belt body, a tensile cord embedded in the belt body, and a jacket defining a pulley contact surface; the jacket having been treated on at least the pulley contact surface with an aqueous dip comprising a dispersion of polyetheretherketone (“PEEK”), an epoxy, and a rubber latex and dried; the jacket comprising a fabric comprising an aramid yarn. 9 . The power transmission belt of claim 8 in the form of a synchronous belt and further comprising teeth defining the pulley contact surface. 10 . An aqueous fabric treatment for a synchronous belt jacket comprising: an epoxy; a rubber latex; and an aqueous PEEK dispersion; wherein the PEEK concentration is in the range of from about 1% to about 5% on a wet weight basis. 11 . An aqueous fabric treatment of claim 10 further comprising graphene or graphene oxide at a concentration in the range of from 0.05% to about 6.0% on a dry weight basis.
