BELT HAVING EMBEDDED TENSION MEMBERS

摘要

In a force transmission belt or a conveyor belt in particular a toothed belt having a main belt body or a cord embedding zone made of a customary belt elastomer (20) in particular of polyurethane and having at least one tension member of carbon cord (10; 1 2) embedded in the elastomer (20) a material (30) is provided which is enclosed between the strands (1) of the cord (10) and which could have been introduced by applying coatings onto strands (1) of the cord (10) for example. Said filler material (30) which is different from the elastomer (20) in which the carbon cord is embedded consists of a composition of hydroxyaromates and aldehydes without any addition of rubber or rubber latex a hydroxyaromates aldehyde resin that does not contain rubber reaction products from hydroxyaromates or hydroxyaromates aldehyde compositions with isocyanates or isocyanate prepolymers and/or aromatically or polyaromatically cross linked polyurethanes or contains these substances. The elasticity of the carbon cord (10; 1 2) is thus successfully maintained good integration in the belt elastomer (20) is ensured and the service time of the belt is substantially increased.
