RUBBER COMPOSITION FOR CLINCH, ITS MANUFACTURING METHOD, AND TIRE HAVING CLINCH USING RUBBER COMPOSITION FOR CLINCH

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition for a clinch reduced in petroleum dependency of a raw material and improved in rubber strength and wear resistance, its manufacturing method and a tire having the clinch using the rubber composition for the clinch. SOLUTION: This tire has the rubber composition for the clinch containing silica 15 to 90 pts.wt. in relation to rubber component 100 pts.wt. containing natural rubber 30 to 90 pts.wt. and epoxidized natural rubber 10 to 70 pts.wt. and the clinch using the rubber composition. As for the manufacturing method for the rubber composition for the clinch, it is desirable that (1) a process for kneading natural rubber and silica and (2) a process for kneading the kneaded material discharged in the process (1) and the epoxidized natural rubber are included.
