| titleOfInvention | Rubber composition and preparation method thereof |
| abstract | The rubber composition of the present invention finely disperses the polyolefin resin (B) in the ethylene / α-olefin / nonconjugated polyene copolymer rubber (A) of ethylene, α-olefin having 3 to 20 carbon atoms and nonconjugated polyene in the molten state. Vulcanizable formulations obtained by In the rubber composition, the average dispersed particle diameter of the polyolefin resin (B) is 2 µm or less, and the blending ratio [(B) / (A)] of the component (B) to the component (A) is in the range of 5/95 to 50/50. to be. By using this composition, when mixing this composition with additives, such as a reinforcing agent, a filler, a softener, a vulcanization accelerator, and a vulcanizing agent, the polyolefin resin (B) which is hard to disperse | distribute can be easily disperse | distributed with a kneading machine. Moreover, by using this composition, it is possible to reliably and sufficiently disperse the polyolefin resin (B) in a short time by a kneader conventionally used in the rubber industry, and as a result, it is possible to easily supply stable high quality rubber products at low cost. The method for producing a rubber composition of the present invention is a ethylene / α-olefin / nonconjugated polyene copolymer rubber (A) of ethylene, an α-olefin having 3 to 20 carbon atoms and a nonconjugated polyene to a multistage vent section extruder via a feed zone. A rubber mixture (E) consisting of 100 parts by weight and 3 to 10 parts by weight of an organic solvent (D) is supplied, and the polyolefin resin (B) is fed to the extruder through another supply zone under an inert gas atmosphere to provide a rubber mixture (E) and a polyolefin. Resin (B) is kneaded and desolvented. According to this method, it becomes an ethylene / alpha-olefin / nonconjugated polyene copolymer rubber (A), and a polyolefin resin (B), contains the polyolefin resin (B) fully disperse | distributed, and it is a vulcanizable ethylene type without blocking. Copolymer rubber composition pellets can be obtained easily. |
