Faserverstärker elastischer Körper und damit hergestellter Treibriemen

摘要

In a V-ribbed belt A, cords 4 made of polyester fibers are embedded into an adhesion rubber layer 2 made of chlorosulfonated polyethylene rubber whose polymer ingredient is so compounded that the content of chlorine is 15 to 35 wt% and the content of sulfur is 0.5 to 2.5 wt%, thereby reinforcing the adhesion rubber layer 2. The cords 4 are treated with two kinds of adhesives. A first adhesive for first treatment is an adhesive having at least one of an isocyanate compound and an epoxy compound. A second adhesive for second treatment is an adhesive formed of a mixture having at least resorcine-formaldehyde resin and 2,3-dichlorobutadiene-contained polymer. A surfactant is added to the second adhesive so that the cords 4 and the adhesion rubber layer 2 are securely adhered, thereby enhancing dynamic adhesive strength of the V-ribbed belt A.
