Title (EN) RUBBER/STEEL CORD COMPOSITE AND PNEUMATIC RADIAL TIRE
(FR) COMPOSITE DE FIL CÂBLÉ CAOUTCHOUC/ACIER ET PNEUMATIQUE À CARCASSE RADIALE
(JA) ゴム-スチールコード複合体および空気入りラジアルタイヤ
Abstract:
(EN) A rubber/steel cord composite which can be sufficiently reduced in the contents of an adhesion promoter and sulfur while retaining satisfactory adhesive properties; and a pneumatic radial tire made using the composite as a reinforcement layer. The rubber/steel cord composite is one obtained by: coating or filling the periphery of or the space between one or more core filaments or core strands with an adhesion-promoter-containing filling rubber (A) to form a core; twisting together a plurality of sheath filaments or sheath strands on the periphery of the core to form a layer-twisted steel cord or multi-twisted steel cord; and coating the outer surface of the layer-twisted steel cord or multi-twisted steel cord with a coating rubber (C). The rubber/steel cord composite is characterized in that the coating rubber (C) contains an adhesion promoter in an amount equal to or larger than the amount of the adhesion promoter contained in the filling rubber (A).
(FR) L'invention concerne un composite de fil câblé caoutchouc/acier dont la teneur en promoteur d'adhérence et en soufre peut être suffisamment réduite tout en conservant des propriétés adhésives satisfaisantes, et un pneumatique à carcasse radiale fabriqué au moyen du composite comme couche de renforcement. Le composite de câble caoutchouc/acier est obtenu par les étapes consistant à : revêtir ou remplir la périphérie d'un(e) ou plusieurs filaments d'âme ou torons d'âme ou l'espace situé entre ces derniers d'un remplissage contenant un promoteur d'adhérence (A) pour former une âme ; torsader ensemble une pluralité de filaments de gaine ou de torons de gaine sur la périphérie de l'âme pour former un câblé métallique à couche torsadée ou un câblé métallique multi-torsadé ; et revêtir la surface extérieure du câblé métallique à couche torsadée ou du câblé métallique multi-torsadé d'un caoutchouc de revêtement (C). Le composite de fil câblé caoutchouc/acier est caractérisé en ce que le caoutchouc de revêtement (C) contient un promoteur d'adhérence dans une quantité supérieure ou égale à la quantité de promoteur d'adhérence contenue dans le remplissage (A).
(JA)  良好な接着性を保持しつつ、接着プロモーターや硫黄の配合を充分に低減し得るゴム-スチールコード複合体およびそれを補強層として用いた空気入りラジアルタイヤを提供することを目的とする。 解決手段としては、本発明のゴム-スチールコード複合体は、1本または複数本のコアフィラメントまたはコアストランドの周囲および間隙に接着プロモーターを含有する充填ゴム(A)を被覆あるいは装填してなるコアの周囲に、複数本のシースフィラメントまたはシースストランドを撚り合わせて層撚りスチールコードまたは複撚りスチールコードを形成し、該層撚りスチールコードまたは複撚りスチールコードの外表面にコーティングゴム(C)を被覆してなるゴム-スチールコード複合体であって、前記コーティングゴム(C)における接着プロモーターの含有量が、前記充填ゴム(A)における接着プロモーターの含有量以上の量であることを特徴とする。
