It is needed.

Generally, a rubber composition having a damping property is used.
Usually, in these rubber compounds, a large amount of carbon black is compounded, a large amount of a softening agent, a plasticizer, and a resin are compounded, or a polymer having a high glass transition point such as high styrene rubber is used. There is.

では安定した性能を示さなくなる。However, when a large amount of carbon black is blended,
This causes a problem that the kneadability and the moldability are deteriorated. Also, if a large amount of a softening agent or a plasticizer is added, the damping property is lowered.
Furthermore, when a large amount of resin is blended or a polymer having a high glass transition point is used, the elastic modulus largely changes with temperature, and stable performance is not exhibited in an actual environment.

ある。From the above situation, the emergence of a rubber compound capable of exhibiting a high damping property in a wide range and having a low temperature dependence of elastic modulus is urgently accompanied by relaxation of transmission of vibration energy and an increase in demand for an absorber. It is an important issue that is required for.

たりして、実配合に供するのが、困難であった。It has been known that when silica is compounded in a rubber composition, it has excellent high damping properties and elastic modulus with little temperature dependence. However, silica has a highly polar and hydrophilic surface due to silanol groups, and is poor in wettability and dispersion with rubber. Further, during kneading, a gel is formed between the rubber and the rubber, the viscosity becomes high, and the workability such as kneading property, extrusion property and calendering property is very poor. Further, the vulcanization accelerator is adsorbed on the silica surface, which delays or hinders vulcanization, making it difficult to use for actual compounding.

As a result, the silanol group disappears, the alkyl group bonds with the siloxane group, and is introduced onto the silica surface. As a result, the disadvantages of silica blending, such as large amount of gel formation, delay of vulcanization, inhibition, and poor dispersion, are solved.

Cost, storage requires a large tank for storage of silica, equipment costs are high, handling is poor, and silica itself is easily dispersed due to fine particles during kneading, which deteriorates the work environment and lengthens kneading. It had the drawback of taking time.

It is not suitable for practical use because it has poor processability such as calendering and extrusion molding, and delays vulcanization. On the other hand, in Examples 1 to 13, the torque value during non-crosslinking was low, kneading processability, extrusion processability, and calendering processability were all good.
Vulcanization is faster. Next, Tanδ, which is an index of damping, is as high as 0.08 to 0.47, and the temperature dependence of the elastic modulus is a low value of 1.2 to 1.7 in terms of the elastic modulus ratio between -10 ° C and 20 ° C. Is shown and is good. Specific surface area of 100 m 2 / g
Comparative Example 2 is shown as a comparative example of the following silica compounding, and Tan δ is as low as 0.03 and there is no damping effect. Further, in Comparative Example 3, when the amount of silica added is as small as 15 parts by weight, Tan δ is as low as 0.03 and there is no damping effect.
