Title (EN) VIBRATION DAMPING RUBBER COMPOSITION AND VIBRATION DAMPING RUBBER
(FR) COMPOSITION DE CAOUTCHOUC AMORTISSANT LES VIBRATIONS ET CAOUTCHOUC AMORTISSANT LES VIBRATIONS
(JA) 防振ゴム組成物および防振ゴム
Abstract:
(EN) According to the present invention, a vibration damping rubber composition is configured to contain the components (A)-(D) described below so that the proportion of the component (B) relative to the total content of the components (A) and (B) is 5-20% by weight. Consequently, the present invention is able to provide a vibration damping rubber composition and a vibration damping rubber, which have a good balance between high damping capacity and low dynamic magnification, while exhibiting excellent heat resistance. (A) a natural rubber, or a rubber blend of a natural rubber and a butadiene rubber (B) a hydrogenated styrene-butadiene block copolymer (C) a sulfur-based vulcanizing agent (D) zinc monomethacrylate
(FR) La présente invention concerne une composition de caoutchouc amortissant les vibrations qui est conçue pour contenir les composants (A) à (D) décrits ci-dessous de telle sorte que la proportion du composant (B) par rapport à la teneur totale des composants (A) et (B) est de 5 à 20 % en poids. Par conséquent, la présente invention est capable de fournir une composition de caoutchouc amortissant les vibrations et un caoutchouc amortissant les vibrations, qui ont un bon équilibre entre une capacité d'amortissement élevée et un faible grossissement dynamique, tout en présentant une excellente résistance thermique. (A) un caoutchouc naturel, ou un mélange de caoutchouc d'un caoutchouc naturel et d'un caoutchouc butadiène (B) un copolymère séquencé de styrène-butadiène hydrogéné (C) un agent de vulcanisation à base de soufre (D) un monométhacrylate de zinc.
(JA) 下記の(A)~(D)成分を含有し、下記の(A)および(B)成分の合計含有量に対する(B)成分の割合が5~20重量%である防振ゴム組成物とする。これにより、耐熱性に優れるとともに、高減衰性と低動倍率との両立がなされた、防振ゴム組成物および防振ゴムを提供することができる。 (A)天然ゴム、または天然ゴムとブタジエンゴムとのブレンドゴム。 (B)水添スチレン-ブタジエンブロック共重合体。 (C)硫黄系加硫剤。 (D)モノメタクリル酸亜鉛。
