（利用分野）
本発明は、防振ゴム用ゴム組成物に関し、耐熱性、低動
倍率で、かつ接着性の良好な主としてエンジンマウント
に用いられるゴム組成物である。DETAILED DESCRIPTION OF THE INVENTION (Field of Application) The present invention relates to a rubber composition for anti-vibration rubber, and is a rubber composition that is heat resistant, has a low dynamic ratio, and has good adhesive properties and is mainly used for engine mounts.
（従来技術）
自動車のエンジンの振動を車体へ伝わるのを防ぐために
防振ゴムの一種であるいわゆるエンジンマウントが広く
使用されている。(Prior Art) A so-called engine mount, which is a type of anti-vibration rubber, is widely used to prevent vibrations from an automobile engine from being transmitted to the vehicle body.
このエンジンマウントはエンジンと接触してこれを直接
支持するものであり、近頃のエンジンの高出力化等に伴
ない、エンジンマウントが使用される雰囲気が高温域と
なるケースが多く、場合によっては１２０’Ｃにも達す
ることがある。This engine mount directly supports the engine by coming into contact with it, and with the recent increase in the output of engines, the atmosphere in which the engine mount is used is often in the high temperature range, and in some cases It can even reach 'C'.
従って、エンジンマウントそのものについて耐熱性が要
求されるようになってきている。Therefore, the engine mount itself is required to have heat resistance.
このような要求に対してはエンジンマウント用のゴム組
成物−中のイオウの量を減らし、加硫促進剤を多く用い
た配合系が多用されている。In response to such demands, compounding systems that reduce the amount of sulfur in rubber compositions for engine mounts and use a large amount of vulcanization accelerator are often used.
しかしながら、基本的にイオウ架橋であるがためにゴム

くならず要求レベルを満たすことができないケースが出
ている。However, because it is basically sulfur crosslinked, the heat resistance of the rubber, such as heat aging resistance and heat fading resistance, is not so good, and there are cases where the required level cannot be met.
またこの系においては静的弾性率Ｅｓの割りには動的弾

約１．４辺りが使用の限度とされる。In addition, in this system, the dynamic modulus of elasticity Ed becomes high compared to the static modulus of elasticity Es, and as a result, the so-called dynamic magnification E d / E s becomes high, and as a result, engine vibration is absorbed by the vehicle body. The original function of the anti-vibration rubber, which is to prevent vibrations from being transmitted, may also deteriorate. The limit of use of such a dynamic magnification is approximately 1.4.
更にこの系では金属とゴムとの接着性が悪くなるため両
者間で剥離が生じやすく、これは重大な事故にもつなが

すると良いが、このケースではゴムと金属との接着性が
十分でなく改良が求められている。In general, in order to lower the dynamic magnification ratio E d / E s , it is better to use carbon black with a relatively large particle size in the rubber compounding system, but in this case, the adhesion between the rubber and metal was insufficient and improvement was required. ing.
（目的）

提供することを目的としている。(Purpose) As a result of efforts to solve such antinomic problems, the present invention has found that a blended system that uses sulfur and bismaleimide together as a crosslinking agent has a dynamic This was based on two new findings: the increase in elastic modulus is small and the adhesion of rubber to metals is improved. The object of the present invention is to provide a rubber composition for anti-vibration rubber.

なる式で示す範囲の配合量としたことを特徴とするもの
である。(Structure) The present invention aims to achieve the above object by using a specific vulcanization system and carbon black with a specific particle size and filling amount, and uses natural rubber or carbon black. This product provides a rubber composition for anti-vibration rubber that is mainly composed of natural rubber and diene-based synthetic rubber and has heat resistance, low dynamic magnification characteristics, and good adhesion to metals. If sulfur and bismaleimir are used as the sulfur agent, and the particle size of carbon black is X (mμ) as a rubber reinforcing agent, the blending amount Y (PHR) is 0.8X+15≧Y (however, if the calculated value is 80 (If Y exceeds 80, Y=80).
ここでイオウと共に用いられるビスマレイミドは次のよ

そして、その使用量は０．５〜５部（ＰＨＲ）であり、
併用されるイオウとの関係においては、対イオウ比０．
５〜１０程度が用いられる。0 0 0 0 (R: alkylene group, cycloalkylene group, oxydimethylene group, phenylene group, sulfone group, other divalent organic group) and the amount used is 0.5 to 5 parts (PHR),
In relation to sulfur used in combination, the sulfur ratio is 0.
About 5 to 10 is used.
なお、イオウはビスマレイミドの活性剤として作用する
ので、若干の併用は必須であるが、量が多い（２ＰＨＲ
以上）とゴム材料の耐熱性が低下してしまうので限界が
ある。Note that sulfur acts as an activator for bismaleimide, so a small amount of sulfur must be used in combination, but in large amounts (2PHR
(above), the heat resistance of the rubber material decreases, so there is a limit.
一方、ビスマレイミドは５部を越えると極端に加硫が遅
くなり、ゴム中への分散が難しくなる欠点かあｔＪ、
０．５部以下になると耐熱性向上の効果が認められない
。On the other hand, if the amount of bismaleimide exceeds 5 parts, vulcanization becomes extremely slow and dispersion into the rubber becomes difficult.
If the amount is less than 0.5 part, no effect of improving heat resistance will be observed.

弾性率Ｅｓと１００Ｈｚでの動的弾性率Ｅｄの比（Ｅ

る場合が多い。On the other hand, the anti-vibration rubber material for engine mounts preferably has a dynamic elastic modulus as low as possible in order to prevent engine vibrations from being transmitted to the vehicle body. Specifically, the static elastic modulus Es of the rubber material is Ratio of dynamic elastic modulus Ed at 100 Hz (E
Rubber having a d/E s ) of about 1.4 or less is often used.

見出したのである。In order to keep this dynamic magnification low, FEF, 5RFFT
It has been found that it is preferable to use carbon black having a relatively large particle size (35 mμ or more) within the range shown above.
そして、その使用ｊｌｕ８０部（ＰＨＲ）を限度とする

加量が少ない方が好ましく、二つには粒径の大きい低補
強カーボンブラックであっても、添加量が８０ＰＨＲを
越えると練り作、業性が悪くなるからである。The usage limit is 80 copies (PHR). The reason why this amount is so popular is that, in order to basically keep the dynamic magnification low, it is preferable to add a small amount of carbon black, and the second reason is that it is preferable to use a small amount of carbon black with a large particle size. Also, if the amount added exceeds 80 PHR, kneading and workability will deteriorate.
なお、カーボンブラックを２種以上併用する場合もある
が、この場合にはカーボンブラックの粒径Ｘは各カーボ

である。Note that two or more types of carbon black may be used in combination, but in this case, the particle size X of carbon black is an average value depending on the use Njl of each carbon black particle size.

... When carbon black having a particle size of X is used together with alPHR, Y4m is calculated using the average particle size X expressed by the following formula.

しかるに加硫剤としてイオウと共にビスマレイミドを用

となることが分かった。However, it has been found that when bismaleimide is used together with sulfur as a vulcanizing agent, a compound for anti-vibration rubber has excellent vulcanization adhesion to metals.
ここで第３表の配合によりゴムと金属との接着性の試験
を行ない、その結果を第４表に示す。Here, an adhesion test between rubber and metal was conducted using the formulations shown in Table 3, and the results are shown in Table 4.

通りである。具体的には動倍率を１．４以下程度にする
のが望まれることは前記した通りである。Table 3 Table 4 Experiment 3 As mentioned above, it is preferable to use a material with a dynamic elastic modulus as low as possible as a vibration-proof rubber material for engine mounts in order to prevent the transmission of engine vibrations to the vehicle body *7: Mainly chlorinated rubber Adhesive 11 (Load Far East Incorporated) *8: Chlorosulfonated polyethylene-based adhesive (Load Far East Incorporated). Specifically, as described above, it is desirable to keep the dynamic magnification to about 1.4 or less.

However, if the rubber does not have a specified particle size and a specified compounding amount, the dynamic magnification, which is the mission of vibration-proof rubber, increases to 1.4 or more, making it unusable. Those within the scope of the invention can maintain dynamic magnification at 1.4 or less, and can be said to be good rubber compositions for use in vibration-proof rubber.
