特性の向上、特に静動比の著しく低減されたゴム組成物
に関するものである。Description: BACKGROUND OF THE INVENTION The present invention relates to a rubber composition having improved dynamic characteristics useful for various rubber products for vibration damping, particularly having a significantly reduced static-dynamic ratio. is there.
［従来の技術］ 最近、防振ゴムに要求される特性が厳しくなってき
た。特に、動的特性の向上、すなわち静動比（動的弾性

ゆるこもり音等の原因になる。[Related Art] In recent years, characteristics required for vibration-proof rubber have become severe. In particular, improvement of dynamic characteristics, that is, reduction of the static-dynamic ratio (expressed as dynamic elastic modulus / static elastic modulus) is the most important issue. When the static-dynamic ratio is high, the effect of suppressing vibration in a high frequency region is reduced, and resonance occurs in the body of the automobile, which causes so-called muffled noise.

ち、この２つの特性を同時に満足する防振ゴム材の開発
が望まれている。In a rubber composition containing carbon black,
It is known that a change in the skeleton structure of carbon black, that is, a change in the particle diameter or the amount of the structure greatly affects the properties of the rubber compound. In general, the static-dynamic ratio can be reduced by using a carbon black having a large particle diameter or a structure having a short structure, or by further reducing the blending amount. However, in order to support a vibrating body such as an engine, it is essential to secure a certain degree of static elasticity (for example, 25% elongation stress in the same shape). However, in the conventional formulation, although the static-dynamic ratio is reduced, there is a problem that the static elastic modulus is reduced. That is, development of a vibration-proof rubber material that satisfies these two characteristics simultaneously is desired.
［発明が解決しようとする課題］ 本発明は、こもり音ような振動に効果のある静動比が

And arrived at the present invention. That is, the present invention has found that a rubber composition having remarkably excellent properties is provided by blending a carbon black subjected to a specific surface treatment of a natural rubber and / or an impregnated synthetic rubber.

The purpose of the present invention is easily achieved by adding 0 parts by weight. Hereinafter, the present invention will be described in detail.

ラックを用いれば良い。The carbon black used in the present invention is not particularly limited as long as it is generally used as a rubber filler, but the particle size is 15 to 100 nm, preferably 18 to 90 nm,

が出来る。In the present invention, a rubber composition having a low static-dynamic ratio and a high static elastic modulus can be obtained by using a carbon black obtained by impregnating a lower amine compound.

アミノブタン、1,3ジアミノプロパン、1,2ジアミノプロ
パン、エチレンジアミンなどである。Examples of the lower amine compound having a linear or side chain having 4 or less carbon atoms used in the present invention include 1,4 diaminobutane, 1,3 diaminopropane, 1,2 diaminopropane, ethylenediamine and the like.

ーボンブラックの表面の酸素コンプレックスとアミン化
合物とがかなり強固に反応している可能性が窮える。Analysis of the volatile component composition of carbon black treated with these compounds indicates that the relationship between the decrease in the amount of carbon dioxide and the increase in the amount of hydrogen gas and methane gas generated and the heat treatment in nitrogen at 200 to 300 ° C are Since they are the same, the possibility that the oxygen complex on the surface of the carbon black and the amine compound have reacted quite strongly is distressed.

果が得られない。Regarding the amount of the amine to be impregnated, the content of the lower amine compound is 0.1 to 5.0% by weight based on carbon black. If the amount is less than 0.1% by weight, a remarkable effect cannot be obtained. If the amount exceeds 5% by weight, no effect can be obtained as compared with the ratio of the amount of the adhesion.

Alternatively, carbon black is used as a water slurry, and an aqueous solution in which an amine compound is dissolved is added thereto.
この乾燥温度は不活性雰囲気ではカーボンブラックの

In the drying in an air atmosphere, the temperature is preferably 200 ° C. or less in consideration of the acidity of carbon black.
