RUBBER COMPOSITION AND MANUFACTURING METHOD THEREFOR, AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To overcome a problem that scorch property is deteriorated by using a polyamide elastomer, where various technologies are proposed in this field for increasing requests of achieving high performance of a tire, for example a rubber composition containing 0.1 to 50 pts.wt. of the polyamide elastomer having the melting point of 100 to 180°C and 1 to 100 pts.wt. of an inorganic reinforcement agent based on 100 pts.wt. of a vulcanizable rubber for improving elasticity, tensile strength, heat generation property and fatigue property.SOLUTION: The above described problem is solved by a rubber composition by blending 100 pts.mass of a diene rubber and 1 to 90 pts.mass of a mixture obtained by mixing carbon black and a polyamide elastomer in advance.SELECTED DRAWING: Figure 1
