Abstract
Official abstract text for this publication.
The present invention provides a rubber composition comprising: a guanidine fatty acid salt (A), which is a salt of guanidine and a fatty acid; natural rubber and/or synthetic rubber (B); and an inorganic filler (C).
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition comprising: a guanidine fatty acid salt (A), which is a salt of guanidine and a fatty acid; a natural rubber and/or synthetic rubber (B); and an inorganic filler (C), wherein the fatty acid in the guanidine fatty acid salt (A) has 3 or more carbon atoms. 2. The rubber composition according to claim 1 , wherein the fatty acid in the guanidine fatty acid salt (A) comprises a fatty acid having 6 to 22 carbon atoms. 3. The rubber composition according to claim 1 , wherein a content of the guanidine fatty acid salt (A) is 0.2 to 5.0 parts by mass based on 100 parts by mass of the natural rubber and/or synthetic rubber (B). 4. The rubber composition according to claim 3 , wherein the content of the guanidine fatty acid salt (A) is 0.5 to 3.0 parts by mass based on 100 parts by mass of the natural rubber and/or synthetic rubber (B). 5. The rubber composition according to claim 1 , wherein the inorganic filler (C) comprises silica. 6. The rubber composition according to claim 1 , further comprising a silane coupling agent (D). 7. The rubber composition according to claim 1 , further comprising a vulcanizing agent (E). 8. A tire comprising the rubber composition according to claim 1 .
