Abstract
Official abstract text for this publication.
The present technology provides a rubber composition wherein from 1 to 100 parts by mass of carbon black and/or from 10 to 150 parts by mass of inorganic filler, from 1 to 30 parts by mass of sulfur-containing compounding agent, and from 0.1 to 20 parts by mass of tin oxide compound, are blended per 100 parts by mass of sulfur-crosslinkable diene rubber; and a pneumatic tire that uses this rubber composition in a cap tread.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition wherein from 1 to 100 parts by mass of carbon black, from 10 to 150 parts by mass of inorganic filler, from 1 to 30 parts by mass of sulfur-containing compounding agent, and from 0.1 to 20 parts by mass of tin oxide compound, are blended per 100 parts by mass of sulfur-crosslinkable diene rubber, wherein the tin oxide compound contains at least a compound represented by formula (1) below: (in the formula (1), n is 1 or 2, and R 1 is a hydrocarbon group having from 1 to 20 carbon atoms, and R 2 is at least one selected from the group consisting of a hydroxy group, —NH 2 , a halogen and hydrogen. 2. The rubber composition according to claim 1 , wherein the sulfur-containing compounding agent is at least one type selected from the group consisting of sulfur, sulfur-containing silane coupling agents, and sulfur-containing vulcanization accelerators. 3. The rubber composition according to claim 1 , wherein the inorganic filler is silica, the sulfur-containing compounding agent contains at least a sulfur-containing silane coupling agent, and an amount of the sulfur-containing silane coupling agent is from 1 to 15 parts by mass per 100 parts by mass of the diene rubber. 4. A pneumatic tire that uses the rubber composition described in claim 1 in a cap tread.
