- Elastomer and cross-linking agent were mixed at 100 ° C for 2 minutes in a closed Banbury mixer (Kobe Steel Works) to produce a compound, and then pelletized with a rubber pelletizer (Moriyama Seisakusho). processed.
- the mold pellets and resin pellets were kneaded with a twin-screw kneader (Nippon Steel Works). Some of the rubber ratios were too high, so the phases were reversed and kneading was impossible.
- the prepared pellets were formed into a sheet with a T-one die forming machine to obtain a sheet of a thermoplastic elastomer composition. The physical properties of the obtained sheet were measured as described above, and the results are shown in Table II.
- Elastomer and cross-linking agent were mixed at 100 ° C for 2 minutes in a sealed pan-parry mixer (Kobe Steel) to produce a compound, and then pelleted with a rubber pelletizer (Moriyama Seisakusho). Processed into a shape.
- a plasticizer for resin buterbenzenesulfonamide, BM-4, manufactured by Daihachi Chemical Industry Co., Ltd.
- the plasticizer-containing resin and the rubber pellets were kneaded again with a twin-screw kneader (manufactured by Nippon Steel) to produce a plasticized elastomer composition pellet.
- the prepared pellets were molded into a sheet using a T-one die molding machine to obtain a sheet of a thermoplastic elastomer composition. The physical properties of the obtained sheet were measured as described above, and the results are shown in Table II. Table m
- Air leak test Using the materials described in each example (thickness 0.15 mm) as the inner liner, tires of 1 9 5/6 5 / R 15 size were manufactured and the air pressure 2 5 0 KPa, 2 5 Measure the change in internal pressure for 3 months under an atmosphere of ° C. Pass the equivalent or higher internal pressure retention rate compared to a tire using a butyl rubber Z natural rubber 80/20% standard inner liner. Anything less than that was rejected.
- a flexible elastic body can be obtained while taking advantage of the properties of a thermoplastic resin.
- an inner liner having both heat resistance, low gas permeability, chemical resistance, and high dynamic durability can be obtained. Because of the same characteristics, it can be used for other parts of pneumatic tires, pipes in hoses, and packing.
