Abstract
(EN)
An anti-vibration rubber composition containing the following (C) and (D) components, and a polymer made from the following (A) and (B) components, wherein the ratio of the (A) and the (B) components, by weight, is in a range where (A)/(B)=9/1-2/8. The present invention thereby satisfies characteristics required for an anti-vibration rubber such as reducing dynamic magnification, while also improving workability of the rubber composition with respect to roll kneading, etc. (A) Natural rubber. (B) Polyisoprene rubber. (C) A filler agent. (D) A dihydrazide compound represented by general formula (1). (In general formula (1), R represents a C1-C30 alkylene group, a C3-C30 cycloalkylene group, or a phenylene group.)
(FR)
L'invention concerne une composition de caoutchouc anti-vibrations contenant les constituants (C) et (D) suivants, et un polymère obtenu à partir des constituants (A) et (B) suivants, le rapport des constituants (A) et (B), en poids, se situant dans une plage où (A)/(B) = 9/1 à 2/8. La présente invention satisfait ainsi les caractéristiques requises pour un caoutchouc anti-vibrations tel que la réduction de l'amplification dynamique, tout en améliorant également la maniabilité de la composition de caoutchouc par rapport au malaxage au rouleau, etc. (A) Caoutchouc naturel. (B) Caoutchouc polyisoprène. (C) Un agent de charge. (D) Un composé dihydrazide représenté par la formule générale (1). (Dans la formule (1), R représente un groupe alkylène en C1 à C30, un groupe cycloalkylène en C3 à C30, ou un groupe phénylène. )
(JA)
下記の(A)および(B)成分からなるポリマーとともに、下記の(C)および(D)成分を含有する防振ゴム組成物であって、(A)および(B)成分の割合が、重量比で、(A)/(B)=9/1~2/8の範囲であるものとする。これにより、低動倍率化等の防振ゴムに要求される特性を満足しつつ、ゴム組成物のロール混練等の加工性が改善される。 (A)天然ゴム。 (B)ポリイソプレンゴム。 (C)充填剤。 (D)下記の一般式(1)に示すジヒドラジド化合物。[上記一般式(1)において、Rは、炭素数1~30のアルキレン基、炭素数3~30のシクロアルキレン基、またはフェニレン基を示す。]
