- the rubber composition of the present invention and the compounded rubber for vulcanization using the same are suitably used for tire applications such as treads, side walls and carcasses, and belts, hoses, anti-vibration rubbers, footwear It can also be suitably used for other industrial products. Among these, it can be particularly suitably used for the tread of a tire.
- Mooney viscosity (ML, 100 ° C.): L rotor according to JIS K6300, preheating 1 minute, mouth
- Scorch property The change in torque is measured by curastometer at 160 ° C. for 40 minutes, and the time to reach 10% of the maximum torque value (t (10)) and the time to become 90% (t It asked for (90).
- Abrasion resistance Measured according to JIS K 6264 using a DIN abrasion tester. The measured value is indexed, and the larger the value, the better the wear resistance.
- tan 5 at 50 ° C. was measured at a dynamic strain of 1%, a frequency of 10 Hz, and 50 ° C. using a dynamic analyzer (RDA) manufactured by Rheometrics, USA. The smaller the value, the smaller the rolling resistance (low rolling resistance), and the better.
- the tan ⁇ at 0 ° C was measured using the same instrument under the condition of a dynamic distortion of 0.5%, a frequency of 10 Hz, and 0 ° C. The larger the value is, the larger the wet skid property (high wet skid resistance), and the better.
- cyclohexane 2,750 g, 40.3 g of tetrahydrofuran, 125 g of styrene and 365 g of 1,3-butadiene were charged.
- the temperature of the reactor contents was adjusted to 20 ° C., and 3.92 mmol of n_butyllithium was added to initiate polymerization.
- the polymerization was carried out under adiabatic conditions and the maximum temperature reached 85.degree.
- Coupling agent Degussa, trade name "Si69"
- Carbon black made by Mitsubishi Chemical Co., Ltd., trade name "Diablack H” Extension oil: made by Fuji Kosan, trade name "Fuccor's Aromax # 3"
- Example 1 SBR-1 for 2 s, (C) component stearic acid 2 phr (2 9 parts by mass with respect to 100 parts by mass of silica) (comparative example 3) power 5 phr (for 100 parts by mass with silica) 1 part by mass) (Example 1), the wet skid resistance (tan 5 at 0 ° C.), rolling resistance (tan ⁇ at 70 ° C.) Both improved.
- the rubber composition of Example 1 also exhibited good scorchability.
- an amino group an alkoxysilyl group
- an epoxy group an epoxy group
- a hydroxyl group a carboxyl group
- a functional group capable of causing an interaction with the surface of silica as a ( ⁇ ) rubber component.
- the rubber composition of the present invention is excellent in scorch property, rolling resistance and wet skid property, and is a rubber composition useful as a material for a low fuel consumption tire, a large tire, and a high performance tire tread.
- the tire, which is used for the tread has high grip and low rolling resistance, and is very useful in the field such as automobiles.
