JP5996941B2 - Rubber composition for pneumatic tread and pneumatic tire - Google Patents

Description

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

Conventionally, a method of blending silica as a filler is known as a technique for reducing rolling resistance of a tire (reducing fuel consumption of a vehicle). For example, rolling resistance can be reduced by blending silica in a tread. At the same time, the WET traction performance can be improved at the same time. Patent Documents 1 to 3 disclose a method of improving fuel efficiency by blending two types of silica having different nitrogen adsorption specific surface areas and particle diameters into a tread. However, there is a limit to the improvement in fuel efficiency when only the tread is improved, and the base tread is also required to have excellent low heat generation.

Unlike the tread, carbon black having a large particle size has been used for the base tread in order to improve fuel efficiency. Therefore, even if part or all of the carbon black is replaced with silica, the effect of reducing rolling resistance is not so great. Moreover, there is also a problem that the fracture strength and workability are reduced by the replacement. As another technique capable of reducing the rolling resistance, a method of reducing the content of the filler is also known, but this method also has a problem that the fracture resistance is lowered. Therefore, there is a demand for a method for improving fuel economy, fracture resistance and workability in a well-balanced manner.
