JP6209320B2 - Rubber composition for tread and pneumatic tire - Google Patents

Description

The present invention relates to a rubber composition for a tread and a pneumatic tire using the same.

As a rubber composition for an automobile tire, a rubber composition containing a conjugated diene polymer such as polybutadiene or butadiene-styrene copolymer and a filler such as carbon black or silica is used. In recent years, due to increasing interest in environmental issues, there has been a strong demand for lower fuel consumption for automobiles, and rubber compositions used for automobile tires are also required to have excellent fuel efficiency. .

As a method for improving fuel economy, for example, Patent Document 1 proposes a method using a diene rubber (modified rubber) modified with an organosilicon compound containing an amino group and an alkoxy group. However, in recent years, further improvement in fuel economy has been demanded due to an increase in interest in environmental problems. In addition, the performance required for rubber compositions for automobile tires includes wet grip performance and wear resistance, but these performances are generally in contradiction to low fuel consumption. It was difficult to obtain a high dimension and good balance.

<Examples and Comparative Examples>
According to the blending content shown in Table 2, materials other than sulfur and vulcanization accelerator were kneaded for 5 minutes at 150 ° C. using a 1.7 L Banbury mixer manufactured by Kobe Steel Co., Ltd. Obtained. Next, sulfur and a vulcanization accelerator were added to the obtained kneaded product, and kneaded for 5 minutes under the condition of 80 ° C. using an open roll to obtain an unvulcanized rubber composition. The obtained unvulcanized rubber composition was press vulcanized with a 0.5 mm thick mold at 170 ° C. for 20 minutes to obtain a vulcanized rubber composition.
Further, the obtained unvulcanized rubber composition is molded into a tread shape and bonded together with other tire members on a tire molding machine to form an unvulcanized tire, which is vulcanized at 170 ° C. for 12 minutes, and tested. Tires (size: 195 / 65R15) were manufactured.

The following evaluation was performed about the obtained vulcanized rubber composition and the tire for a test. The results are shown in Table 2.

(Rolling resistance)
Using a rolling resistance tester, the rolling resistance when a test tire was run at a rim (15 × 6JJ), internal pressure (230 kPa), load (3.43 kN), speed (80 km / h) was measured and compared. It was displayed as an index when Example 1 was taken as 100. A larger index is better (low fuel consumption).

(Wet grip performance)
Each test tire was mounted on all wheels of a vehicle (domestic FF2000cc), and a braking distance from an initial speed of 100 km / h was determined on a wet asphalt road surface. The result is expressed as an index. The larger the number, the better the wet skid performance (wet grip performance). The index was calculated by the following formula.
Wet skid performance = (braking distance of comparative example 1) / (braking distance of each formulation) × 100

(Abrasion resistance)
Using a LAT tester (Laboratory Abrasion and Skid Tester), the volume loss of each vulcanized rubber composition was measured under the conditions of a load of 50 N, a speed of 20 km / h, and a slip angle of 5 °. The numerical value (LAT index) in Table 2 is a relative value when the volume loss amount of Comparative Example 1 is 100. The larger the value, the better the wear resistance.

By combining the specific modified conjugated diene polymer rubber in the present invention with a silica mixture having a low specific surface area and a high specific surface area, the performance balance of low fuel consumption, wet grip performance and wear resistance can be remarkably improved. It was. In particular, from the evaluation results of Comparative Examples 1, 2, 4 and Example 1, it became clear that the performance balance can be improved synergistically by the combined use.
