Definitions
- the present invention relates to a rubber composition for an anti-vibration rubber that can be suitably used for an anti-vibration rubber used in a high temperature environment such as an automobile torsional damper, an engine mount, and a muffler hanger.
- the basic characteristics of such anti-vibration rubber are required to be strength characteristics that support heavy objects such as engines and vibration-proof performance that absorbs and suppresses the vibrations. Furthermore, the performance required for vibration-proof rubber used in a high-temperature environment such as an engine room is required to have high heat resistance and durability as well as low dynamic magnification and excellent vibration-proof performance. In particular, in recent years, the engine room temperature tends to rise as the engine output is increased and the space in the engine room is reduced due to the expansion of the indoor space, etc., and it is often used in more severe environments. Therefore, the requirements for heat resistance and the like of the vibration-proof rubber for automobiles are becoming more severe.
- Patent Document 1 Japanese Patent Application Laid-Open No. 2006-131871
- Patent Document 2 Japanese Patent Application Laid-Open No. 2006-143859 proposes a technique of blending a base rubber with a large particle size and high structure carbon in order to achieve both low dynamics and heat resistance.
- Patent Document 2 proposes a technique of blending a base rubber with a large particle size and high structure carbon in order to achieve both low dynamics and heat resistance.
- the relationship between low dynamics and heat resistance and the relationship between low dynamics and durability are trade-offs, and dynamic magnification is reduced and durability is further improved compared to the above-mentioned conventional technology. It is hoped that
- the present invention has been made in view of the above circumstances, and an object thereof is to provide an anti-vibration rubber composition that can achieve both low dynamic ratio and high durability, and an anti-vibration rubber obtained by curing the rubber composition. To do.
- the present inventor has mixed a diene rubber with a small particle size, carbon black and silica, thereby achieving a low dynamic magnification at a high dimension that could not be achieved conventionally. It has been found that it is possible to achieve both durability and durability, and the present invention has been made. That is, the anti-vibration rubber composition of the present invention uses a small particle size carbon, which was difficult to apply in the prior art, and partially replaced this with silica to achieve a reduction in dynamic magnification and high durability. It has been made.
- the present invention provides the following rubber composition for vibration-proof rubber and vibration-proof rubber.
- a diene rubber and carbon black and silica as fillers, and the blending ratio of carbon black (a) and silica (b) is (a) / (b) 80/20 to 20
- NR natural rubber
- butadiene rubber are used in combination as the diene rubber.
- the anti-vibration rubber composition of the present invention can achieve both high anti-vibration performance (low dynamic magnification) and high durability.
- a diene rubber is used as a rubber component.
- a known rubber can be used, and is not particularly limited. Specifically, known natural rubber, butadiene rubber, styrene-butadiene rubber (SBR), isoprene rubber, styrene.
- -Synthetic rubber such as isoprene copolymer, butyl rubber, halogenated butyl rubber, chloroprene rubber, isobutylene-isoprene rubber, acrylonitrile-butadiene rubber, epoxidized natural rubber, acrylate butadiene rubber, and the molecular chain ends of these natural rubber or synthetic rubber Modified ones can be used, and one of these can be used alone, or two or more can be used in combination.
- natural rubber, butadiene rubber, and styrene-butadiene rubber (SBR) can be preferably used.
- rubbers other than the diene rubber can be blended in the rubber component.
- examples of the rubber include acrylic rubber and ethylene-propylene-diene rubber (EPDM).
- the vulcanizing agent is not particularly limited, and examples thereof include sulfur and peroxides.
- sulfur the amount is 0.1 to 5 parts by weight, preferably 0.2 to 3.0 parts by weight, based on 100 parts by weight of the rubber component. If these blending amounts are deviated, the crosslink density of the rubber is increased, and there is a risk that basic physical properties such as vibration proofing performance and durability are deteriorated.
- a peroxide can also be used as a vulcanizing agent, and a commercially available product can be used singly or in combination of two or more.
- the compounding amount of these vulcanizing agents is usually 1 to 10 parts by mass, preferably 2 to 8 parts by mass with respect to 100 parts by mass of the rubber component.
- this amount exceeds 10 parts by mass, the rubber may be cured too much, leading to a decrease in elongation at break and a decrease in durability.

In the present invention, HAF can be preferably used. Moreover, these carbon blacks may be used individually by 1 type, and may use 2 or more types together. Further, it is preferable to use carbon black satisfying an iodine adsorption amount of 40 to 140 g / kg and a DBP oil absorption amount of 90 to 160 ml / 100 g.
- the durability could be improved with such a small particle size / carbon black, but the dynamic magnification increased and was not adopted.
- the dynamic magnification can be reduced.
- the blending amount of carbon black is preferably 10 to 80 parts by mass with respect to 100 parts by mass of the rubber component from the viewpoint of reducing the dynamic magnification.
- silica As a filler, and it is particularly preferable to use silica gel having a nitrogen adsorption specific surface area (BET method) in the range of 80 to 230 m 2 / g. If the BET specific surface area is less than 80 m 2 / g, it is difficult to ensure sufficient durability, and if it exceeds 230 m 2 / g, it is difficult to disperse the silica gel in the base rubber.
- the blending amount of silica is preferably 10 to 80 parts by mass with respect to 100 parts by mass of the rubber component from the viewpoint of reducing the dynamic magnification.
- a silane coupling agent can be contained in the silica.
- a 1 type, or 2 or more types can be used for a well-known commercial item.
- the amount of the silane coupling agent is 1 to 10% by mass, preferably 5 to 10% by mass, based on the amount of silica. If the blending amount is less than 1% by mass, the effect of improving the dispersibility and reinforcing properties may not be sufficiently exhibited. On the other hand, if the blending amount exceeds 10% by mass, the effect commensurate with the blending amount cannot be obtained. This is not preferable from an industrial and economic viewpoint.
- oils can be used, and are not particularly limited. Specifically, process oils such as aromatic oils, naphthenic oils, paraffin oils, vegetable oils such as palm oil, alkylbenzene oils, etc. Synthetic oil, castor oil, etc. can be used. These can be used individually by 1 type or in combination of 2 or more types.

- the fatty acid may be a saturated, unsaturated, linear or branched fatty acid, and the number of carbon atoms of the fatty acid is not particularly limited, but for example, 1 to 30 carbon atoms, preferably 15 to 15 carbon atoms.
- fatty acids more specifically, cyclohexane acid (cyclohexanecarboxylic acid), naphthenic acid such as alkylcyclopentane having a side chain, hexanoic acid, octanoic acid, decanoic acid (including branched carboxylic acid such as neodecanoic acid), Saturated fatty acids such as dodecanoic acid, tetradecanoic acid, hexadecanoic acid, octadecanoic acid (stearic acid), unsaturated fatty acids such as methacrylic acid, oleic acid, linoleic acid, linolenic acid, resin acids such as rosin, tall oil acid, abietic acid, etc.
- cyclohexane acid cyclohexanecarboxylic acid
- naphthenic acid such as alkylcyclopentane having a side chain
- hexanoic acid octa
- zinc white and stearic acid can be preferably used.
- the amount of these vulcanization accelerating aids is preferably 1 to 15 parts by mass, more preferably 2 to 10 parts by mass with respect to 100 parts by mass of the rubber component.
