Embodiment 1 to 10 and comparative example 1 to 7

[0084] A rubber composition for anti-vibration rubber to be used as each sample was prepared according to the component composition listed in Table 1.

[0085] The rubber composition for anti-vibration rubber of each sample was heated at 155° C. for 30 minutes to 90 minutes to perform a vulcanization treatment, thereby preparing a sample of a crosslinked rubber composition for anti-vibration rubber.

[0086] (evaluate)

[0087] Each sample of the crosslinked rubber composition for vibration-proof rubber was evaluated in terms of (1) hardness, (2) static spring constant, (3) loss, and (4) dynamic amplification.

[0088] (1) Hardness (Hd)

[0089] The hardness of each sample of the vulcanized rubber composition for anti-vibration rubber was measured according to JIS K 6253 (type A). The measurement results are listed in Table 1.

[0090] For the measured hardness, the larger the value, the higher the hardness.

[0091] (2) Static spring constant (Ks)

[0092] The static sprin...

Abstract

The present invention solves the problem of providing a rubber composition for anti-vibration rubber which has excellent high loss properties and maintains a good low dynamic amplification ratio. In order to solve this problem, the present invention is characterized by comprising: a rubber component containing a diene rubber; carbon black of greater than 0 parts by mass and 10 parts by mass or less with respect to 100 parts by mass of the rubber component; and with respect to 100 parts by mass of The rubber component is 50-70 parts by mass of oil.

Description

technical field [0001] The present invention relates to a rubber composition for anti-vibration rubber and an anti-vibration rubber for vehicles. Background technique [0002] Anti-vibration rubber is a material that is placed in various vehicles such as automobiles at locations that are sources of vibration and noise for the purpose of improving ride comfort. For example, in order to reduce vibration or noise entering the room, anti-vibration rubber is used for components such as torsional dampers, engine mounts, and muffler hangers, which are the main sources of vibration and noise. Thereby absorbing vibrations when the engine is driven and reducing vibrations entering the vehicle interior or both noise and diffusion of noise to the surrounding environment. [0003] As basic characteristics of such anti-vibration rubber, strength characteristics for supporting a heavy object such as an engine and anti-vibration performance for absorbing and suppressing the vibration there...
