Abstract
The invention is directed to a drive belt of rubber or rubber-like plastic having a surface protection (5) which includes polyamide-containing textile reinforcement and/or polyester-containing textile reinforcement. On the outer side, a surface coating (6) of a friction-reducing material in a matrix of at least one elastic addition polymer is provided. For improved heat resistance with good protection against wear, the elastic addition polymer has at least 2% by weight based on the polymer of structural components —O—CxRy—O— with x=1-3 and y=0-6. The R in a structural component can be the same or can be different and is selected from hydrogen and/or carbon-containing groups.
Claims14
Drive belt of rubber or rubber-like plastic having, at a surface thereof, protective textile reinforcement which contains polyamide and/or polyester, and, at the outer side of the textile reinforcement, a coating comprising friction-reducing material in a matrix of at least one elastic addition polymer, wherein the elastic addition polymer has less than 2% by weight, based on the polymer, of —O—CxRy—O— structural components wherein x=1-3, y=0-6 and R is selected from hydrogen and/or carbon-containing groups and can be the same or different in a structural component.
Drive belt of at least one of the above claims, wherein the friction-reducing material is a fluoropolymer powder.
Drive belt of at least one of the above claims, wherein the friction-reducing material is present in the matrix in quantities of 40 to 60% by weight.
Drive belt of at least one of the above claims, wherein the belt is a rubber toothed belt.
