Abstract
Official abstract text for this publication.
Provided is a modified rubber for a tire (A) obtained by modifying a natural rubber and/or a synthetic rubber with a compound represented by formula (1): wherein X is an acid to form a salt with a guanidine site.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition for a tire comprising: modified rubber for a tire (A) obtained by reacting a natural rubber and/or a synthetic rubber with a compound represented by formula (1) wherein X is an acid to form a salt with a guanidine site and the acid is selected from oxalic acid and inorganic acids; a filler containing an inorganic filler (B); and a silane coupling agent (C). 2. The rubber composition for the tire according to claim 1 , wherein the natural rubber and/or the synthetic rubber is mixed with the compound represented by the formula (1) and modified in the range of 20 to 180° C. 3. The rubber composition for the tire according to claim 1 , wherein the compound represented by the formula (1) is used at 0.01 to 10% by mass, based on an amount of the natural rubber and/or the synthetic rubber. 4. The rubber composition for the tire according to claim 1 , wherein the inorganic filler (B) is silica. 5. The rubber composition for the tire according to claim 1 , wherein the filler comprises carbon black. 6. The rubber composition for the tire according to claim 1 , wherein the rubber composition is obtained by mixing the compound represented by the formula (1), the natural rubber and/or the synthetic rubber, the filler containing an inorganic filler (B), and the silane coupling agent (C) together. 7. The rubber composition for the tire according to claim 6 , wherein a temperature in mixing is in a range of 20 to 180° C. 8. The rubber composition for the tire according to claim 6 , wherein a content of the compound represented by the formula (1) is 0.01 to 10% by mass, based on an amount of the natural rubber and/or the synthetic rubber. 9. A tire using the rubber composition according to claim 1 for a tread of a tire member.
