Abstract
Official abstract text for this publication.
Provided are a rubber composition that is environmentally friendly and achieves both excellent breaking properties and low energy loss, and a tire that includes a component prepared using the same and is environmentally friendly and excellent in rolling resistance properties and durability. The present invention provides a rubber composition containing a rubber component, a specific chemically modified microfibrillated cellulose, and carbon black.
First claim
Opening claim text (preview).
The invention claimed is: 1. A rubber composition, comprising a rubber component, a chemically modified microfibrillated cellulose, and carbon black, the chemically modified microfibrillated cellulose having a structure in which part of the hydroxyl hydrogen atoms of microfibrillated cellulose is replaced with a substituent represented by the following formula (1): -A-R 1 (1) wherein R 1 represents a C3-C30 hydrocarbon group having at least one unsaturated bond, and A represents a carbonyl group (—CO—),and wherein an amount of the carbon black is 5 to 200 parts by mass per 100 parts by mass of the rubber component. 2. The rubber composition according to claim 1 , wherein the chemically modified microfibrillated cellulose has a degree of substitution of 0.05 to 2.0. 3. The rubber composition according to claim 1 , wherein an amount of the chemically modified microfibrillated cellulose is 0.5 to 10 parts by mass per 100 parts by mass of the rubber component. 4. The rubber composition according to claim 1 , wherein the chemically modified microfibrillated cellulose has an average fiber diameter of 2 to 100 nm. 5. A tire, comprising a component prepared using the rubber composition according to claim 1 .
