Abstract
Official abstract text for this publication.
A rubber composition capable of improving all of processability, abrasion resistance, rolling resistance property and wet skid performance and a pneumatic tire using the same are provided. A rubber composition comprising 25 to 100 parts by weight of a surface-treated silica based on 100 parts by weight of a rubber component comprising a natural rubber and/or a diene synthetic rubber, the surface-treated silica being obtainable by mixing a silica and a sulfur-containing organic silicon compound represented by the general formula (1): or the general formula (2): in an amount of 1 to 20 parts by weight of the sulfur-containing organic silicon compound on the basis of 100 parts by weight of the silica under a temperature of 130° to 180° C.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for producing a rubber composition, which process comprises: heat-treating silica at 105 to 130° C. to adjust the water content of silica before the silica is mixed with a sulfur-containing organic silicon compound; providing a sulfur-containing organic silicon compound represented by the general formula (2): wherein in formula (2) ea…
