Beschreibung
Zusammenfassung:	A belt with a tensile cord embedded in an elastomeric body, having an adhesive composition impregnating the cord and coating the fibers. The adhesive composition is the reaction product of a polyisocyanate and a polyol, or a polyurethane prepolymer derived therefrom, and a polyamine curative and optionally additional polyol, and with optionally added plasticizer. At least one of the polyisocyanate, the prepolymer, and the polyamine are blocked with a blocking agent. The belt body may be of cast polyurethane, vulcanized rubber, or thermoplastic elastomer. The cord may have an adhesive overcoat. 一种具有包埋在弹性体主体中的张力帘线的带，其具有粘合剂组合物，该组合物浸渍所述帘线和涂覆所述纤维。该粘合剂组合物是多异氰酸酯和多元醇，或者是衍生自它们的聚氨酯预聚物，和多胺固化剂以及任选的另外的多元醇的反应产物，并且具有任选加入的增塑剂。该多异氰酸酯、预聚物和多胺中的至少一种是用封闭剂封闭的。该带主体可以是流延聚氨酯、硫化橡胶或者热塑性弹性体。该帘线可以具有粘合剂外涂层。
