摘要

"Composition based on rubber and pneumatic component of the composition of elastu00c8mero based on diene with dispersion of gru00e1nulo in the format of an ear of corn".This invention relates to a rubber composition and pneumatic possessing at least one component of a rubber composition comprised of at least one based on diene elastomer.With the exception of butyl elastomer type, which contains an internal dispersion of granules in the form of an ear of corn.This rubber component can be, for example, a tread of pneumatic and / or canvas rubber reinforced with rope and / or belt.A tread of the tyre used to run during the winter, although not necessarily limited to the act of driving during the winter.It is composed of a rubber composition containing at least a sulphur vulcanisable elastomer based on diene having a Tg below - 30 198 C and an internal dispersion in this point of gru00e2nulThe shape of an ear of corn.The running surface of the tread of the tyre is configured with a combination of micro protrusions of granules in the format of the cob of the internal dispersion of granule in the foRmato of maize ear and micro cavities that point created by a release of a portion of the protruding granules in the form of ear of corn during the wear or use of the running surfaceThe tread of the tyre as the tyre is running.At least a portion of those micro granular protrusions shaped ear of corn may be covered by a relatively thin rubber membrane to the tread.The granules in the form of ear of corn may be colored with a suitable dye of a color that is not black to contrast with the tread color to better visualize their presenceT in the running surface of the tread.The composition of rubber from the tread may contain optionally also a composite of starch / plasticizer ester sorbitan monoleate, methylene donor compound.Receiver of methylene compound or combination of compound methylene donor and recipient, and can be enhanced with smoke black, aggregates of synthetic amorphous silica or their combination.
